I. INTRODUCTION
WeatherView™ is a low cost electronic weather information system utilizing the new Weather
Module specified by C-MAP Marine Forecast in order to meet the market demand for a marine information
system regarding weather and weather related services. The main purpose of WeatherView™ is effective
downloading, presentation and easy distribution of various types of geo-referenced weather information as
overlay of global coverage of electronic navigational charts provided by the world-wide Electronic Chart
Database CM-93 Edition 3.0 from C-MAP. WeatherView™ can access the Z and A scale (“overview charts”).
For detailed chart combined with the Weather Module, we recommend OceanView.
WeatherView™ is primarily aimed for on board purposes, but it also covers the need of organizations
and commercial companies involved with the management of the shipping business and marine environment
protection. Many other potential users such as marine universities, navy, public libraries, research centers
should find it useful for their purposes as well.
WeatherView™ is a powerful tool for creation and distribution of geo-referenced weather information.
This is part of the C-MAP contribution to safety of navigation and the environmental protection of our
Oceans.
II. GENERAL INFORMATION
1.0 Electronic charts
CM-93/3 is a specially compiled database of electronic charts comprised of objects and their attributes as
defined by the IHO S-57 Edition 3.0 standard. CM-93/3 is fully compliant with the S-57/3 data format, and in
addition the CM-93/3 distribution conventions allow the mariner to immediately use the required chart
coverage, including automatic updating.
The CM-93/3 Worldwide Chart Database contains over 20,000 electronic charts grouped into the
following scale layers:
Scale name
Letter symbol
Scale range
Background, small scale
Z
1:5,000,001 – UNLIMITED
Background, medium scale
A
1:1,500,000 – 1,5,000,000

2.0 The combination of seamless coverage and bookmarks
The CM-93/3 database provides seamless cartographic coverage. In addition to this, the user can save
the current view as a geo-referenced bookmark. There are two types of bookmarks implemented in the
system. Personal bookmarks allow saving views within the current window and providing fast panning to any
point of interest. Shared bookmarks can be saved as a file with the users own defined name and contain all
current chart settings such as database version, data set name, coordinates of screen, presentation model,
display mode, scale, zoom factor, and references to all user objects that were displayed on the screen. The
bookmark files can be managed as any standard Windows files: placed in the chosen directory, saved on
diskette, forwarded to another computer in the office network or sent as a binary attachment to an e-mail.
Such a unique combination of seamless coverage combined with the bookmark feature gives the user
both freedom of easy navigation in the worldwide electronic chart database and quick restoration of all chart
settings that were made during the previous working session.
This feature allows a fast and easy way of exchanging geo-referenced information between the members
of a working group within the office network or by Internet, and even via direct communication channels such
as GSM or Inmarsat.

IV. GETTING STARTED
1.0 About this Manual
This Manual is written under the assumption that the user is familiar with the main principles of the MS
Windows environment and its applications.
All dialog names, their fields and environment terms are written in bold.
Any program messages are italicized (e.g.: “Please enter the necessary value”).
In order to improve the visual information in this user’s manual, the following logical simplifications will be
used:
File Æ Open
i
!
for example, instead of using the expression “select Open in the File menu”, we will rather
use; “File Æ Open.”
When you see this sign it means that a topic contains additional information. This
information is unnecessary for WeatherView™ operation, but it may be useful for
completely understanding of its functions.
Important information is marked with this sign.
2.0 System Requirements
WeatherView™ is a PC based Windows application. The program will run on almost any IBM compatible
PC with an Intel Pentium™ processor. However, we recommend at least a 500 MHz processor with 128MB
RAM. The system must also contain a CD-ROM drive.
Please note that WeatherView™ is designed to run under Microsoft Windows 98 (Second Edition), NT™,
Windows 2000 or Windows XP. If the PC does not have either of these, it must be upgraded before the
installation of WeatherView™.
In order to download weather information (see chapter VII 1.0), internet connection (either by http or
email) is needed (but only when downloading the dataset or when system updates are required).

¾ To insert a point before the first one – Move the mouse pointer over the first point. The thin red line will
be linked to it instead of the last point. Now, move the mouse to the position you want and a new point
will be added before the first one. In the same way you can move the mouse pointer over the last point to
keep on adding points from the last one.
¾ Delete point – In order to delete a point, move the mouse pointer over it. The thin red line
will be absent but a special symbol will be displayed. Press the RIGHT mouse button to
delete the point.
¾ Move point – In order to move a point, locate the mouse pointer over it and press the LEFT
mouse button. A special symbol will be displayed. Choose the new point position and press
the LEFT mouse button again. The point will be moved. Press ESC to cancel the operation.
¾ Insert point between two existing points – In order to insert a point between two existing
points move the mouse pointer over the line between them. A special symbol will be
displayed. Press the LEFT mouse button, choose the new point position and press the LEFT
mouse button again to insert a point. Press ESC to cancel the operation.
If you want to change the Measurement tool settings, select: Tools Æ Options Æ
Measurement:
!
You can edit the following settings:
¾ measurement units: meters or nautical miles
¾ display directions or not (Show bearing option)
¾ compute legs as great circle or lines (Great circle option).
Last update: 27 June 2006
Page 20
WeatherView™ User’s Manual
In the great circle mode, a leg always consists of a number of rhumb lines with limited length.
The value of that limit is set so as to get negligible errors. Therefore, in this mode, you will see
several values of direction along the line when the Show bearing option is on.
i
!
Besides that, when you move the cursor along the great circle line you can notice the
appearance of the “Delete point” symbol which should be displayed above the point only. It
means that the “separation” point is actually under the cursor but just hidden. This feature with
“separation” point affects the appearance of this symbol only, and does not affect any other
measurement functions.
When you work with several windows and you would like to unify these setting for all windows
switch on the option Tools Æ Options Æ General Æ Apply settings to all Map Windows. If
this is not checked then these settings are applied for the active window only.
5.2 ERBL (Electronic Range Bearing Line) tool
Select Tools Æ ERBL. The ERBL is displayed on the screen.
Choose the ERBL center position and fix it with the RIGHT mouse button. After that, a range circle and a
bearing line will show the range and the bearing from the
center point to the mouse pointer position. In the lower left corner of the Chart window, the range values are
in nautical miles (Rng), the bearing from the center point to the cursor (Brg to) and back (Brg from) are
displayed.
Press the RIGHT mouse button again to release the ERBL.

The plotting principles are the same as for the Measurement tool (see chapter V 6.0). They are listed
here once again.
!
The term “waypoint” means the geographic position where a vessel’s course should be altered.
The term “leg” means a line between two adjacent waypoints and the vessel’s track between
them accordingly.
¾ Add waypoint. Click with the LEFT mouse button on the chart. A waypoint number (1) in a blue circle will
appear. Move the cursor and a thin red line linking the point and the mouse pointer is displayed. It can be
useful for checking the leg and the second waypoint position. Click with the LEFT mouse button in new
position on the chart. The second waypoint (2) will appear. The next LEFT click will plot the next
waypoint and so on.
¾ Checking waypoint position. Pressing and holding down the LEFT mouse button while adding waypoints
allows controlling the waypoint position. Release the mouse button to plot the waypoint.
¾ Pan the Chart window or zoom it with a boundary box press and hold down the CTRL key. While the
CTRL key is held down you can pan and zoom with a boundary box the same as in ordinary chart
view mode (for zoom out press and hold down the CTRL and SHIFT key simultaneously)
¾ Insert waypoint before the first one. Move the mouse pointer over the first waypoint. The thin red line will
be linked to it instead of the last waypoint. Click with the LEFT mouse button. A new point will be inserted
before the first one. In the same way you can move the mouse pointer over the last waypoint and resume
adding waypoints from the last one.
¾ Delete waypoint. In order to delete a waypoint move the mouse pointer over it. The thin red
line will be absent but a special symbol will be displayed. Press the RIGHT mouse button to
delete the waypoint.
¾ Move waypoint. In order to move a waypoint, locate the mouse pointer upon it and press the
LEFT mouse button. A special symbol will be displayed. Choose the waypoint position and
press the LEFT mouse button again. The waypoint will now be moved. Press ESC to cancel
operation.
¾ Insert waypoint between two existing waypoints. In order to insert a waypoint between two
existing waypoints move the mouse pointer over the leg between them and a special symbol
will be displayed. Press the LEFT mouse button, choose the waypoint position and press the
LEFT mouse button again to insert a waypoint. Press ESC to cancel operation.
i
Please note that while you are plotting or checking the waypoints, you can use the ERBL tool
(Tools – ERBL, see chapter V.6.2). Click with the RIGHT mouse button on a land feature to fix
the ERBL and move the mouse pointer to the position where you are going to plot a waypoint.
The ERBL will display the distance and the bearing to that land feature.

3.2 Control buttons
When you go into the edit mode, a new control buttons appears on the right side of the
Functional panel.
¾ The Save button allows you to save the edited route. It will actually save all of the changes
made since the editing start. Once the route is saved, you may exit from the Edit mode (the
route is deactivated) and the standard Route Planning panel appears. The route will still be
loaded and shown.
¾ Save as will save the route with a different name. The Save route as… window will appear
where you can type another route name. After you exit from the edit mode, your initial route is
unloaded (hidden) and a new (renamed) route is loaded and shown.
¾ The Show button changes the scale and screen position in order to view the whole route in
the Chart window.
¾ The Parameters button shows a dialog box for editing the Route parameters. It consists of
two panels: Change Settings and Default settings.
i
Š
Default settings – sets default route parameters. These are applied for new legs only.
Š
Show speed – When it is switched on, the speed is displayed on the legs. Please note that when
one of the leg waypoints is outside of the Chart window limits, the speed is shown above the visible
waypoint.
Š
Show bearing – Like the speed setting, when it is switched on, the courses are displayed on legs.
Š
Schedule Named WP only (Schedule) – When it is on, only the named waypoints are displayed on
the Schedule panel.
Š
Change settings – allows the unification of Common settings for several legs of the route. When you
reset a setting, it will be the same for all legs in an interval defined by WP (Waypoints) diapason.
A route is logically divided and consists of three sections: Outward (Berth to Pilot station), Sea
passage (Pilot station to Pilot station) and Inward (Pilot station to Berth). Select waypoints for
outward section (for example, 1 to 9), set Voyage part Type for them (Outward accordingly) and
set (change) all parameters (Speed, Deviation, etc.) for that Type. Press Apply button. (See also
chapter VII.4.3)
Note: only highlighted parameters will be changed. On the picture above the legs will not
become Rhumb lines!
The idea is during Maneuvering these parameters are usually completely different to Sea
passage parameters. By means of Type selection for a route Section (with defining waypoints
forming it) you can easily change those parameters.

¾ Charts button – displays all WeatherView™ charts in the limits of which the route is plotted. Be aware
that only background chart is supported in WeatherView™.
¾ Cancel button – allows exiting from the edit mode canceling all changes made. Once the route is
canceled, you may exit from the Edit mode and the standard Route Planning panel appears. The route
is unloaded.
¾ Export Table function – is represented by the
icon. This important tool exports to MS Word the
current table in view (Waypoints or Schedule).
After export you can print your
table.
3.3 Waypoints panel
This is the list of waypoints. The table consists of the following parameters for each waypoint:
¾ WP – Waypoint number
¾ LAT – Waypoint latitude
¾ LON – Waypoint longitude
¾ Radius – Estimated turning radius at the waypoint expressed in meters. The default value is set in the
Route parameters dialog box (see chapter VII.4.2).
i
This parameter is supposed to be used in high accuracy navigation. WeatherView™ draws an
arc at the waypoint depending on the turning radius value. If you expect turning at some
waypoint with a different radius you can change the value (this radius depends on vessel’s
speed, rudder angle, etc). If you do not want to use this parameter you may set it to zero.
If WeatherView™ is unable to calculate a maneuver correctly (when angle between legs is too
acute) it does not draw an arc.
Last update: 27 June 2006
Page 27
WeatherView™ User’s Manual
¾ Dev – Deviation or Cross Track Error (XTE) along the leg from this waypoint to the next. It is expressed
in meters each side of the leg. The deviation is an analog of accuracy and it is used for determining
dangers and cautions along the route (see chapter VII.4.6). The default value is set in the Route
parameters dialog box but it can be changed in the table.
¾ Speed – Estimated speed on the leg from this waypoint to the next expressed in knots. The default value
is set in the Route parameters dialog box (Economic Speed).
¾ Rhumb L (Rhumb Line) – A choice of whether Rhumb Line (
) or Great Circle (
) sailing will be
applied from the waypoint to the next one. When you activate the Great Circle checkbox in the Route
parameters dialog, all of the new legs will be calculated as Great Circle lines.
!
These four parameters (Radius, Deviation, Speed and Rhumb Line) may be reset in the Route
parameters dialog box. You should set the appropriate values in the Common settings section,
activate the checkboxes and press OK button. The parameters will be set the same for all
waypoints.
¾ Distance(Nm) – It is the leg distance from the waypoint to the next one expressed in Nautical Miles. The
Distance is calculated automatically.
¾ DTA – Distance to Arrival or Distance to Go – the distance from this waypoint to the last one of the route
(destination) expressed in Nautical Miles.
¾ Time – Estimated time that will be spent for sailing from this waypoint to the next. It is calculated
automatically.
¾ Name – The name of waypoint. You are not obliged to type any waypoint name but it is advisable.
¾ In port – Voyage Part Type or Mode of Voyage. The value in this column can be “Sea passage”,
“Inward” or “Outward”. “Inward” means that the route starts from Pilot station to Berth, “Outward” from the
Berth to Pilot station and “Sea Passage” – from Pilot station to Pilot station.
By default all legs are marked as “Sea Passages”. You can change the value by double clicking
on the cell. However a more convenient possibility is by using the Change settings dialog box of
the Route parameters window (see chapter VII.4.2).
It is strongly recommended to set this parameter properly in order to get the correct speed, ETA
and fuel consumption calculation and reflect it in the report.
i
In order to change any of the above mentioned parameters (except Distances, Time and In Port)
click with the LEFT mouse button in the chosen cell of the table, type in desired value and press
ENTER.
By using the keyboard only, you can “navigate” around the table with the ARROW keys and start
editing by pressing any key.
In this way you have an important possibility to type in waypoint positions. You may need this if
you copy a route from a paper source for example.
The last row in the table is empty. If you start editing any cell in that empty row a new waypoint is
added. This feature allows you to enter new waypoints without reference to the chart.
In order to delete a waypoint using the keyboard only, press the DELETE key while any cell
(except LAT, LON and Name) in the waypoint row is selected.

Double click on the waypoint number (or by pressing ENTER on the keyboard while that field is
selected) to center the Chart window on the selected waypoint.
3.4 Schedule panel
The Schedule panel defines your route schedule
The following parameters are included in the table:
¾ WP – Waypoint number. The list of waypoints is taken from the Waypoints table;
¾ Name – The waypoint name;
¾ Arrival – Date and time of arrival from the waypoint;
¾ Departure – Date and time of departure from the waypoint;
¾ Stop dur. – Stop duration at the waypoint. It can be applied for waypoints representing pilot stations and
ports, as in WeatherView™ a route can include a number of intermediate ports of call;
¾ Speed – Estimated speed in knots on the leg from this waypoint to the next. It is taken from the
Waypoints table and can not be changed here;
¾ Distance - The leg distance from the waypoint to the next one expressed in Nautical Miles. The Distance
is taken from the Waypoints table;
¾ Time to Next – Time that will be spent to reach the next waypoint. It is calculated as Speed divided by
Distance;
Last update: 27 June 2006

WeatherView™ User’s Manual
The Arrival, Departure and Stop duration parameters can be changed. In order to do this, click
with the LEFT mouse button in the chosen cell of the table, type in desired value and press
ENTER. Using the keyboard you can “navigate” around the table with the ARROW keys and start
edit by pressing any key.
The last edited cell is highlighted with a red font color. By default the departure time from the first
waypoint is highlighted.
The initial value of departure time from the first waypoint (Port) is the time and date when the
route was created.
i
When you change any of editable parameters, WeatherView™ calculates new values of
corresponding parameters because they are linked with arithmetic formulas. For example, you
set an arrival time at some waypoint. It means that you would like to arrive to that waypoint (Port
or Pilot Station) at a certain time. But it is impossible, as this arrival time depends on the
departure time from the previous waypoint and speed during leg passage. Theoretically, any of
those parameters could be changed for conformity. However, in this case, WeatherView™ will
change the departure from the initial waypoint thus shifting the whole schedule. The following
table clarifies what is changed while you edit a parameter.
You edit…
Is changed…
Arrival
Departure time from the initial waypoint.
Departure from initial waypoint
All schedule.
Departure from any other
point
Stop duration
Stop duration at the same waypoint. However, if you
decrease Departure time and the Stop duration is less than
the value of your decrease (in fact get a Departure time less
than Arrival time) this operation is blocked. If the Stop
duration is zero (no waiting) you are not able to reduce
Departure time at all.
Arrival time at the next waypoint and the whole schedule
after.
Bear in mind that the program does not realize the full reality of your schedule. It allows setting
Stop duration at open sea, instant speed increasing and decreasing and so on. The operator will
only check its schedule.

3.5 Charts
!
Note: WeatherView™ supports scales A and Z only, and this option is therefore of limited
interest. For both combined weather and chart, we recommend the OceanView software.
When you press the Charts button on the Control box of the Route planning panel all charts in the limits
of which the route is plotted are displayed in the Chart window and listed in the created Charts panel.
In the Chart window you can see Chart borders and names of appropriate Datasets (electronic chart
names). When you move the mouse pointer to a chart border the Dataset name is displayed as a Tooltip.
In the Charts table you can see some additional Chart information, such as Scale, Edition Number, Issue
Date, etc.
If you click on the chart border with the LEFT mouse button this chart is selected in the table. Double
click on the any field of the chart in the table and that chart will be highlighted in the Chart window.
You can sort charts in the table. Select the field that you want to use as criterion for chart sorting. Press
(Ascending order) or
(Descending order) button located in the upper right corner of the Charts
the
panel. The charts will be sorted appropriately.

4.0 Routes management
4.1 Working with several routes
After completing the route creation, checking it and pressing the Save, Save as or Cancel buttons you
exit from the Route Planning Æ Edit mode. The ordinary Route Planning panel appears. It consists of the
list of available routes and control buttons in the right part:
Available routes are the routes registered by WeatherView™. They are your own created routes with
Route Planning (see chapters VI.2.0) as well as imported routes. Route name, Port of departure and Port of
destination set in the Add new route window are displayed here.
With a LEFT mouse click, you can select any routes. While holding down CTRL key you select all routes
you click and with the SHIFT key you select all routes in the list between two last clicked. This is a standard
feature for many programs and is applied in most WeatherView™ lists.
The control buttons are applied for selected route(s) and they mean the following:
¾ New – A new route will be created;
¾ Edit – The selected route is loaded and activated. You enter the edit mode. At the same time chart scale
and position are arranged to display the whole route on the screen. You can edit only one route at a time;
¾ Rename – A Modify-route-info window appears. It looks exactly as the Add-new-route window. The
Route, Port of departure and Port of destination names may be changed here. You can rename only one
route at a time.

¾ Delete – The route will be deleted (unregistered);
¾ Show – The route will be loaded and shown. The chart scale and position are arranged accordingly to
display the whole route on the screen;
¾ Hide – The route will be hidden and unloaded;
¾ Close – The Voyage planning tool will be closed. You have the possibility of doing the same by releasing
the
i
button on the Toolbar or pressing by the
button;
Please note that when you close the Voyage report tool, a route is activated (in the Edit mode).
This route is not deactivated (you can continue editing on the chart). Besides that, all loaded
routes are not unloaded and the Route monitor will still be presented on the screen. Thus,
closing the Voyage planning tool just gives you more space in the Chart window, but it does not
affect any route operation.
On the left side of the route name, in the Available routes list, you will notice a checkbox. When
you switch it on the route is loaded and shown, but the scale and screen position are not
changed as they are with the Show button. When you switch it off, the route is hidden and
unloaded.
All loaded routes are marked in the checkboxes.
The Routes monitor is displayed in the upper left corner of the Chart window. Move the mouse pointer
upon it and the list of all loaded routes will be displayed.

On the picture above you can see three loaded routes in the Routes monitor box. They are marked also
in the Available routes list and they are shown on the chart.
The Route monitor also allows the management of loaded routes. Three buttons are provided for this
purpose:
(Hide) button is equal to Hide button on the Route planning panel. The route will be hidden and
unloaded.
(Show) button is equal to Show button on the Route planning panel. The route will be shown, scale and
screen position changed in order to display the entire route on the screen. This feature may be useful even
when the route is shown already but not on the entire screen.

5.0 Tidal predictions
All tidal information is accessed via the
button, or Tools Æ Tides command. Once this icon is
pressed, small blue diamonds appear on the chart. These represent the tidal prediction points (locations)
around the world. In total, there are about 4000 of the tidal diamonds.
Click with the RIGHT mouse button on any of these diamonds to see the tidal height prediction.
By default, the tidal diagram is calculated for the current date (today). This date is displayed in the Date
indicator.
Tidal height is dependent of Time and is graphically expressed on the diagram.
Heights are in meters above the Chart Datum.
Time is the Standard Time of the country concerned.
The diagram background consists of three color zones. These zones graphically show night time
(grey), daytime (green) and twilights (blue).
i
In addition to this, there is a very useful feature within this diagram. When you move the mouse
pointer over the diagram area, it becomes a cross. When you move the cross-pointer position,
the time and the corresponding tidal heights are shown allowing you to obtain detailed tidal
information.
Please note that you do not need to move the cross-cursor precisely over the line. Only the
horizontal movement (time) affects the tidal height figure.
The time and tidal height for maximum high water and minimum low water are given on the left
part of the panel in the Locations box.
You can see several entries in the Locations list if you have clicked on a small scale chart and

1.0 Downloading weather data
When installing WeatherView™ , a dedicated download software, named C-MAP Terminal, is installed as
an integrated part of WeatherView™ . The download function can be activated in three modes: one
EasyMode mode (see 1.1 below), one DirectView (see 1.2 below) mode and one Customized mode (see
1.3 below). The EasyMode is the most user friendly, while Customized gives you most options.
i
The EasyMode mode is the fastest and easiest way to download and view weather, and we
recommend this option for daily inspections especially when connected to the internet.
The Customized mode will allow you to customize the scheduled weather data (get weather
data from server) and where to save downloaded information (e.g. on local disk, on CD, on USB
pen, etc).
1.1 Downloading Weather with “EasyMode”
EasyMode is the most recent feature in the WeatherView™ software. It was incorportated in version 2.0.
It simplifies the communication between WeatherView™ and the C-MAP Terminal (See the next subsections
for information on how to download Weather dataset in other ways). When opening WeatherView™ it will
always be in EasyMode.
In order to activate EasyMode when using other functions, one needs to select the
icon in the Weather Presentation Panel, as shown below:
Last update: 27 June 2006
Page 38
WeatherView™ User’s Manual
The EasyMode toolbar consists of 6 buttons:
1)
Download – by clicking on this button, the user will be directed to a map window. From this
window, the user can select and define the region of interested for the downloading of weather
dataset:
By clicking on the map, the user can move the center position of the map. The plus (+) and
minus (-) buttons are used for zooming in or out, respectively.
i
For selecting a new region, click on the button “New Area”. After that, draw a rectangle around
the region of your interest.
After selecting the region, click on the “OK” button. The C-MAP Terminal will then download the
dataset for you.
!
2)
Pressure – The pressure dataset is plotted on the map (for the region selected);
3)
Wind – The wind dataset is plotted;
4)
Precipitation – The precipitation data is plotted. When this button is activated, the “Waves” button
is deactivated and vice-versa. This is because the plotting of waves and precipitation is done
through filled contours. If both variables would be plotted together, it would be difficult to
read/interpret the results.
5)
Waves – The wave dataset will be plotted;
6)
Cyclones – The cyclone information will be plotted. This button is only activated when there are
cyclone warnings.
All of the buttons from the EasyMode toolbar are pre-defined. The objective is to make the task
of downloading weather dataset easier and faster.
For customized options, see the next subsections.

WeatherView™ User’s Manual
Full Weather Panel: to adjust the presentation according to your request.
Reduced Weather Panel: Used to show only time information when inspecting data in full screen mode. The
small up/down arrow to the bottom right is used to toggle.
In the “Time slider/information” window you can adjust the time for presentation either
by editing the “Date-box”, by dragging the slider or by clicking the animation buttons:
Buttons are: First step, one step Backward, Play/Stop animation, one step Forward and
Last step respectively. Time step in presentation can be set to 1, 3, 6 or 12 hours.
The Time interpolation is used if you choose a time step less then the least time step available in the
originating weather data. To distinguish interpolated time step from original time step, the interpolated
parameters will turn cursive in the “Meteo Parameters” window:
!
Last update: 27 June 2006
Page 43
WeatherView™ User’s Manual
In the “Meteo Parameter” window you can:
• Turn on/off parameters by marking in the left column (example: Total waves in figure below)
• Choose presentation modus for each Meteo Parameter:
o Area: Filled contour according to legend
o Cont: Contoured lines (e.g. isobars for air pressure)
o Symb: Vector parameters (e.g. wind) are shown with strength and direction,
Scalar parameters (e.g. air pressure) are shown with a “ X –symbol “ only
o Text: Numeric value is shown in each single grid point, e.g. for waves; each text box
showing wave height [m], period [s] and direction [deg] (in addition “Area” and “Cont” is
turned on) :
Linear interpolation in space and time is used to smoothly display the weather data. No special
procedure is applied close to land. When the parameter names are not cursive (like in the
above example), the “Text” option will give you non-interpolated values in the original Grib-file
only.
.
Measurement Units: In this column you may state your preferred units. By left-double-clicking
on a unit box, you will have a scroll list in which to choose preferred unit, e.g. for wind four units
are possible:
i
In the “Weather legend” box the Meteo parameter in question, i.e. the one marked blue in the
“Meteo Parameter”- column, has its corresponding legend.
Short key: When in chart window, you can step forward and backward in time by holding down
ctrl key + cursor arrow:
<Ctrl-key> + <right arrow -key> : one time step forward
<Ctrl-key> + <left arrow -key>
: one time step backward
<Ctrl-key> + <up arrow -key>
: increase time step to next step (e.g. from 3 to 6)
<Ctrl-key> + <down arrow -key> : decrease time step to next step

4.0 Alarms
In the Weather Alarm Area panel, one can manage alarm thresholds for wind, waves, etc. Enter the
Weather Alarm Area panel by left click
, or from the menu: Weather Æ Alarm Area Settings:
How to define an alarm:
1) Left click on button [Add condition], a blue line will appear – double click this to edit:
2) Choose “Met parameter”, and then type (“Value of”):
3) Choose alarm interval (“Value from” and/or “Value to”):
4) Choose an operator if you have two or more parameters defined. The operator might be AND or OR.
- AND: the alarm will be made for areas where both thresholds are true
- OR: the alarm will be made for areas where at least one of the thresholds are true
In this case the alarm is true if the wind is above 35 knots AND the temperature is below 2˚C, i.e. icing
conditions.
5) You might also load predefined or user defined alarms by using the Save and Load buttons:

The weather alarm criteria are calculated for every point of GRIB’s space/time grid based on
condition entered by user in the Weather Alarm Area panel.
5.0 Tropical Cyclone Warnings (TCW)
For downloading Tropical Cyclone Warnings, see VII. 1.4 Download Tropical cyclone files.
The presentation of Tropical Cyclone Warnings (issued by the World Meteorological Organization, WMO) is
activated from in the Weather Presentation Panel or by choosing the Tropical cyclone icon:
Observations and prognoses have different symbols according to the legend provided on the screen. By
moving the cursor over a point, you can inspect details for wind speed and wind gust.
If a route is passing close to an already downloaded cyclone warning, an alarm will be indicated by a purple
line (both in chart and in timeseries). The alarm zone around the cyclone has a form of broadening
from 100 NM to 500 NM lane built on the cyclone track, starting from the last known observation.

(“never cross the track” rule plus error area on both side of track depending on validity of
prediction: 0(obs): 50NM, 24h: 100, 48h: 150, 72h: 200, 96-above: 250NM)
The alarm zone is applied to the route part starting from the last observation time:
1) for the route part preceding the last observation time no alarm is issued;
2) if the route crosses the above mentioned alarm zone after the last observation time, then
those legs are considered dangerous regardless of its schedule times.
!
Alarm concerning Tropical Cyclones close to route: If a route is passing close to an already
downloaded cyclone warning, an alarm will be indicated by purple line. This is based on the
above described calculation regarding distance from cyclone track. When in cyclone areas we
always recommend you to update cyclone files regular and inspect them manually. For detailed
information you are requested to ask your nearest WMO Cyclone Warning Center.

6.0 Ice Coverage
For downloading of Ice Coverage information, see VII 1.5 Download Ice Concentration.
The presentation of the Ice Concentration / Ice Coverage follows the guidelines issued by World
Meteorological Organization (see color legend in below figure). The Ice Concentration is activated in the
Weather Presentation Panel or by choosing the Ice Concentration icon:
!
The Ice Coverage is an observation based on yesterday’s satellite observation of the ice edge.
This should be used as a guild line for today’s ice coverage. It should under any circumstances
NOT be used for navigation close to or into the ice!
i
To toggle the ice, you should first move the time stamp to yesterday’s date at 12:00 UTC. This
is due to all yesterday’s satellite information has to be integrated into one time stamp.

7.0 Route comparison
By testing alternative routes, one will easily pick the best route depending on the user’s defined weather
alarms. When using the “drag and drop” functionality of ship symbols on routes, the program recalculates the
time and redraws the weather and positions of other ships. If you have some number of alternative routes,
this feature provides a good overview. Weather information is available for ten days ahead. In the “Edit”
mode one can print a word document of the route including arrival and departure to/from all waypoints.
By activating the “Weather Timeseries” panel, one obtains all detail of weather along the defined route:

VIII. Ship Response: Simple Harmonic Motion (Roll, Pitch and
Heave)
The response element of WeatherViewTM is related to the sea state condition during the vessel’s
voyage along a planned route. It helps the user get information about swell and total waves, as well as
information on the roll, pitch and heave.
i
Before reading on, the first step to be able to take advantage of the response feature is to create
a route. For more information on how to create and plan your route, refer to chapter VI (Route
Planning).
1.0 Features of the Ship
After planning your route, you should inform the features of the ship. This may be done by selecting:
Weather Æ Ship Response Æ Ship Response Options. The following window will appear:
SHIP DATA:
Length
Length at waterline (LWL) of the vessel, m.
LWL is the length of the vessel as measured from the bow ending of the waterline to the stern ending.
Width
Beam, the widest width, of the vessel, m.
Draft
Draft of the vessel, m.
Displacement
Displacement of the vessel, tons.
ADDITIONAL DATA (if known):
Angle of vanishing stability
Sets angle of vanishing stability (AVS) of the boat, degrees.
AVS is the angle the boat can heel and still right itself.
Waterline area coefficient
Waterline area coefficient, non-dimensional quantity.
Effective waterline area
Effective waterline area, m².
Transverse metacentric height
Transverse metacentric height of the boat, m.
Transverse metacentric height is the vertical separation of the center of gravity and the transverse metacenter

By saving the ship dataset, the user may load this information for further use.
2.0 Inspect the Ship Position
Now, click on Weather Æ Ship Response Æ Inspect Ship Position, to obtain the information
related to the sea state and response by each timestep of a planned route. A window called “Inspect Ship
Position” will appear. After that, click on the desired ship symbol along a plotted route. WeatherViewTM will
mark the position of your vessel with a red color. This is shown in the figure below informing the user about
the sea state and response for this specific position (Note that the route is crossing the path of a the cyclone
ALBERTO-06):
Last update: 27 June 2006
Page 55
WeatherView™ User’s Manual
The Inspect Ship Position window will inform you about
the Roll, Pitch and Heave information on the bottom left.
On the bottom right, you can see the weather
information for the position of the vessel, for example,
Pressure, Temperature, Wind, Cyclone, etc, according to
your selections (See Figure on the left, Cyclone:
ALBERTO-06).
!
The upper dark blue arrow represent the direction and
period of the total sea. The lower blue arrow represent
the direction and period of the swell.
Wind arrow in upper right corner
The ship is plotted in the middle. The arrow pointing
outwards shows the direction and velocity of the
vessel.
“Red Shadow” zone indicates the danger of having a sudden increase in roll amplitude (and in worst
case capsizing) of the vessel having given combination of speed and bearing. The conclusion is
made from comparison of ship's natural roll period with relative wave period: if the difference
between values is less than 30% then resonance can occur. This combination can in some cases be
dangerous. An alarm for a given threshold of roll amplitude can be made in the Alarm Panel.
IX. PREPARATION OF PRESENTATIONS
1.0 OVB Bookmarks
OVB means OceanView Bookmark. These bookmarks are an external WeatherView™ bookmarking
system. The principal difference of the external bookmarks from the internal ones is the following: External
bookmarks are saved as standard MS Windows files (with .ovb extension) in a user predefined folder. You
can work with these bookmark files just like any other MS Windows files. For example, you may send and
receive them from other WeatherView™ users.
When you double click on a file with an .ovb extension in the MS Windows environment, it will
automatically run WeatherView™ with the saved view at the startup instead of world map.
Press the
button and the standard Save As window appears.

accessed in the File menu. Deleting and renaming can be performed as usual in the Open and
Save windows.
A default folder for external bookmarks can be set up in the Tools Æ Options Æ File locations
dialog box.
2.0 Sending OVB Bookmarks by E-Mail
It is also possible to send OVB Bookmarks by E-Mail directly from WeatherView™ ™.
Select the File Æ Send Æ Bookmark command.
Your default E-mail program will be run. The OVB
bookmark will be attached to the auto-generated
E-Mail.
Select a Recipient and send the E-Mail.
