Basic operation
Basic operation
Do not turn off the machine during startup, as this may
damage the Olex installation!
Olex is a complete system for seabed mapping, plotting and
navigation. By using GPS and echo sounder, position- and
depth data are measured and saved to the system. These data
are continuously recalculated and added to previous
measurements. The result is visualized as a realistic 3-D
image of the seabed.
After a few seconds the machine will halt, and a blue screen
with an overview of available screen configurations is
displayed.
The system has advanced features for navigation, with the
possibility of software extensions for Sonar, ARPA, ITI, AIS,
wind - and oceanic currents measurements.
The most widely used installation is on the M1- machine, but
Olex can also be installed on a laptop or a desktop PC.
On initial startup or when changing monitor, select screen
configuration by using the arrow keys to move the marker up
or down. The recent screen settings will be suggested next
time the system is started.

HARDWARE: Echo sounder
INTERFACE: Serial port or ethernet (ES60)
SOFTWARE: Olex normal installation
HARDWARE: GPS receiver
INTERFACE: serial port/USB
The depth panel displays the depth of the last sounding.
The depth values may be provided by a single beam echo
sounder, or a multibeam echo sounder. If there are more then
30 seconds from the last received depth message, the
numbers will turn gray. This time may vary, depending on the
type of echo sounder.
Position, course and speed is displayed in the GPS panel.
These data are usually provided by the GPS receiver, but can
also come from other sources such as AIS, radar or a multibeam echo sounder. If multiple sources are available, signals
from the GPS receiver are given priority. If positioning
messages from the GPS is not available, the system uses
messages in order of priority from the AIS, multi-beam echo
sounder or radar.
If Settings → Show calculation progress is turned on, a green
dot flashes in the panel for each registered depth echo. If the
echo sounder detects hardness, this dot may appear in
different colours.
-both depth and hardness are registrated.
- depth values are registrated, no hardness.
- no depts nor hardness values are registrated.
The view can be changed by clicking repeatedly inside the
window.
By clicking inside the depth panel, an echogram displaying
the last measured depths, opens.
The bottom line shows the number of satellites and quality of
the position. Low HDOP - horizontal dilution of precision,
means good position accuracy. Numbers below 4 is
considered as good positioning accuracy. If the quality of the
GSP signal is poor, the numbers will turn red and the seabed

Seafloor mapping
Seafloor mapping
When Olex receivs signals from GPS and echo sounder, the
system will automatically start calculation of seafloor maps.
Position, bottom- and possibly hardness data, if available, are
stored in boxes that are either measured or calculated. Depth
data may come from various sources, such as single-beam
echo sounder, echo sounders with hardness - ES60 , and
multi-beam echo sounders.
See “Seafloor hardness - ES60” on page 65, “MBES MultiBean Echo Sounder” on page 59 and “WASSP” on
page 61.
Data can be imported and exported, via backup, data export,
raw-data files and depth databases. The seafloor map can be
displayed in different ways, with contours, relief, bottom
hardness, bottom zoom and 3D. Any errors that occurs during
the surveying can afterwards be removed in different ways.
The earth surface is divided into small squares, called depth
boxes. Each box is 5x5 metres, unless a different resolution is
chosen. This resolution is chosen to match the position
accuracy of a conventional GPS. If a more accurate GPS is
connected, the resolution can be changed.
A depth box can contain either a measured or a calculated
value. When the echo sounder receives a value, the value is
stored in a deep box, and the system will calculate the depth
values in a given radius around this.
By zooming in, one depth value is displayed in each depth
box. Measured values are red and calculated values are dark
gray.
By activating Boxes in the main menu, it is possible to see
the values of the vertical soundings, which will be either red
or yellow. Depth boxes with red numbers contains data from
the Olex shared database, and yellow numbers are self-measured depth values.
If Settings → Show calculation progress is turned off, all
numbers will be red.
The quality of the seafloor map depends on how many depths
that are measured. The more depths measurements in the
same area, the better the serafloor map.
If the same depth box is measured several times, the most
shallowe value is used.
www.olex.no

Seafloor mapping
Create seafloor maps
Echo sounder with bottom hardness
Depth data is the basis for the seafloor maps, and may come
from various sources.
On the basis of raw data from the echo sounder, Olex
calculates the seabed topography and hardness. This is done
based on the seabeds ability to reflect sound, adjusted for
factors that may affect the measurements.
Without HT-software, the data will be treated as data from a
csingle beam sounder, where only the depths are transferred
via serial cable.
The hardness is displayed with colors. Each color
representing a hardness value. Turn on the hardness view by
clicking Hardness in the main menu.
Single beam echo sounder
To get the best possible result of the seafloor mapping, it is
important to set the correct parametres for the sonar depth,
sound velocity and location of the depth sounder. In addition,
values for the GPS and the boat's geometry must be set. Click
Settings → Edit and use the arrow keys to change the values.
Different parameters can can be set to optimize the
calculation.
The hardness is expressed in percentage, where 0 % is completely soft and 100 % is maximum hard. The hardness of the
last recorded sounding appears in a separate panel to the
right. The hardness value is also displayed in the depth flag
that appears when the mouse pointer moves around the in the
screen. See also“Seafloor hardness - ES60” on page 65.
Multi beam echo sounder
Seafloor calculation
• Optimal - performs a quality check before the values are
used in the calculation.
Multibeam echo sounders are used primarily for surveys and
seafloor mapping, providing a significantly better accuracy
than conventional single-beam echo sounders. On the basis
of incoming position- and depth data ,Olex can calculate the
seafloor map. Measured and calculated dept data are added
continuously to a depth database
More information see “MBES - MultiBean Echo Sounder”
on page 59, “WASSP” on page 61 and “Databases” on
page 37.
• Always - uses all depth values.
• Stopped - turns off the calculation.
Seafloor calculation should normally be set to “Optimal” for
a best result.
Calculation limit
Sets the upper limit of depth values to be used for calculation.
This should normally be set somewhere between 5 metres
and 100metres.
Appropriate recommendations may be 5m or 10m.

By clicking this, the numerical values of the depth of the
boxes will be visible on the screen instead of contours.
Depths and contours can not be displayed simultaneously.
Contour lines
In traditional presentation, the seafloor map, with contours or
depth numbers, is displayed on the screen. The seafloor map
is displayed in blue tones, ranging from bright blue that
means shallow areas, to dark blue that means deeper areas.
The colors are allocated from the surface down to a certain
depth value, which can be set in the menu bar. All seafloor
deeper than this value gets the darkest shade of blue.
The map will still have the same colors for the depth areas.
Relief
This function is activated by clicking Relief on the top menu.
Depth countours are displayed and visualized by the use of
light and shadow. This displays edges and countours, and the
detail becomes more visible. A good relief view, depends on
if the area has a well-measured seafloor map.
The depth range is set by clicking the arrow buttons on the
main menu, minimum depth is 5 meters and maximum depth
is 9000 meters.
Equidistance - the depth difference between each contour
line, automatically adjusts the selected depth range.
The equidistance can also be set manually by clicking on the
value in the depth contour panel at the bottom of the screen.
When Relief is activated, a control panel opens in the lower
left corner.
If the map is zoomed in enough, a new button, Depths, is
added to the depth contour panel.
Greyscale displays the Olex map in gray colour, with only
light and shadow.
By clicking Left or Right, you can select the light falling onto

Bottom zoom
The Bottom zoom function is used to view certain areas in
greater details. By activating Bottom in the top menu, the
seabed where the depth falls within a certain range, is
displayed in details.
This presupposes that there are already seafloor maps in the
area. Areas without seafloor maps are shown as white .
Special colors are used to distinguish the bottom zoom range
from the rest of seafloor map. Bottom zoom depth range has
an upper and a lower depth limit, centered around a center
depth. The center depth is either the depth beneath the
vessel, the depth below a mark or it can be set manually.
The depth range between each color is adjusted by using the
the arrow keys in the bottom zoom panel.
By changing the color range, the bottom zoom depth range
changes correspondingly.

The settings for the bottom zoom range is defined at the top
of the panel. A higher color separation, means a broader
zoom range.
By clicking on the arrows that change the color separation,
one will see that the bottom zoom range depends on the color
separation.
The centre depth is changed by clicking the arrows, << and
>> changes the depth by 10 meters for each click, while <
and > changes the distance by 1 meter.
When the bottom zoom depth range is set, the parameters can
be stored for later by clicking Lock.
When Bottom is activated later, the previous settings are
recalled.
If Lock is activated when the panel opens, it means that
manual mode was used the last time the bottom zoom feature
was used.
No other depth data turns off and on all other colors than the
bottom zoom colors.
Hot colors change the color spectrum from cool blue tones to
warm colors.

Seafloor mapping
Color separation
Setting the zoom depth manually
15 colors are distributed evenly in the bottom zoom depth
range. Each depth range is assigned to one specific color. If
the color separation is set to 1 meter, this means that depth
areas that have less than 1 m depth difference will have the
same color. Bottom zoom range will be 15 meters.If the color
separation is increased to 5 meters, the depth areas that varies
by less than 5 meters, will have the same color. And the
bottom zoom range will be 75 meters.
The color distance is adjustable from 0.1 to 500 meters.
An other way to set the zoom depth, is to adjust it manually
by clicking the adjustment buttons on the panel. Notice that
the Lock button will be activated automatically when
adjusting the settings. The button must be pressed again to
return to zoom depths determined by the ship's position, or a
mark.
Zoom depth below vessel
Instead of using a mark to determine the zoom depth, and the
zoom depth has not been set manually, the depth below the
ship at any time determines the zoom depth. This is indicated
by that the zoom depth changes constantly, as the ship sails
ahead.
No other depth data
This function turns off the the seafloor map view, displaying
only areas with bottom zoom colors.
No zoom bottom point
On the first picture is the color space set to 1 meter, on the
other photo the color separation is increased to 5 meters.
If a mark is placed somewhere outside the measured seafloor
map, the zoom depth cannot be determined, and the message
“No bottom zoom point” will be displayed.
Zoom depth
The zoom depth can be specified in several different ways.
Profile
A mark determines the zoom depth
Select an existing mark, or place a new mark. Click the
Bottom button in the main menu. The depth below this mark
now determines the zoom depth.
If the mark is moved to a deeper or shallower water, the zoom
depth changes, and hence the bottom zoom range.
After the zoom range is selected, click Lock to keep the
setting. The selected mark can then be closed for editing by
clicking Finish on the chosen mark panel.

Seafloor mapping
Area and volume calculations
In areas with seafloor maps, Olex can calculate the volume of
water- and seafloor mass within a limited area.
Start by creating an area, then set the upper and lower limits
for the volume to be calculated.
If some of the area is going to cover landareas only "wet"
area twill be calculated.
Start by creating an area.
IIf the numbers are numbers stand unchanged, ie, 0 as the
upper value and 9999 as lower depth, only the water volume
will be calculated.
Terrain volume is calculated only if the lower value is no
deeper than 100 meters below the deepest seabed in the area.
Then click Volume.
The following values are calculated:
• Wet area - projected area of seabed within the selected
area.
• Water volume - volume of water within the given area,
bounded by the upper and lower depth limit.
• Mean Depth - The average depth in the area.
Set the upper and lower depth values, by clicking on the
numbers and then change the depth values.
• Terrain Volume - Volume of terrain mass between the
upper and lower depth.
The accuracy of volume calculation depends on the
resolution of the seafloor map. To calculate a small area
accurately, the seafloor map must have a higher resolution
than usual.
Enter the new value and click Ok.

Seafloor mapping
Remove depth errors
Depth values that creates unwanted and abnormal formations
in the seafloor map, are usually considered as depth errors.
These may appear as peaks or holes in the bottom map, or
longitudinal edges or scars. Depth errors can occur for
various reasons. The most common reason incorrect sonar,
settings, noise or variations in the sound velocity which is
caused by the temperature and salinity. By studying the
seafloor maps using relief, 3-D view, and bottom zoom, it is
easy to locate depth errors and delete them. When one or
more depth errors is deleted, the machine will start the
recalculation of the seafloor map. Note that this may take
some time depending on the complexity of the seafloor map.
1.
First, select Boxes to see the vertical soundings.

Raw data from the sonar are sent to Olex, and the system can
calculate the seabed topography and hardness.
The calculation is done based on the seabed’s ability to
reflect sound signals, adjusted for factors that can affect the
measurements.
Without the HT-software, data from the Simrad echo sounder
will be treated as data from a common echo sounder, where
only the depth values are transferred via serial cable.
The hardness is displayed in colors, each color representing a
hardness value. Click Hardness in the main manu to turn on
the view.
Adjusting the hardness colors
The panel at the lower left shows the hardness colors spread
on a scale from 0% to 100%.

separate panel to the right. The hardness value is also shown
in the depth flag that appears when the mouse cursor is
moved around.
The buttons at the bottom of the window are used to change
the color spread.
The colors are spread linearly from 0%
to 100%. Each color will always have the
same hardness.
The colors are spread evenly from the
lowest to the highest value.

Auto pilot
The time of arrival will be changed
Under correction - for short term correction on autopilot. The
ship turns too late and the price becomes unstable.
Over correction - for long-term correction on autopilot - the
ship turns before it should.
Correction of autopilot lag
To keep the best possible course when the ship navigates
along a line object with several waypoints, it is important to
add the correction of autopilot lag.
Olex navigates towards the last waypoint of each line. When
the pointis passed, starts navigation towards the next
waypoint.
By adding the correction of autopilot lag, Olex will calculate
the ship's probable position in x seconds.
If it is estimated that the waypoint is passed, Olex starts
navigation towards the next way point immediately, so that
the course line is as straight as possible.
The correct path - make time added on correction for delayed
autopilot.
Without correction, the autopilot will calculate the new
course first after the waypoint is passed.
It takes some time to maneuver the ship, and the number of
seconds of correction varies from ship to ship and must be
tested.

Current map
The moon's position relative to earth is considered to be the
main source of tidal currents.
The Olex system calculates ocean currents in relation to the
“lunar half day”, having a duration equivalent to the tidal
rhythm.
The lunar half day is divided into 12 lunar hours, and by
observing the current in the individual lunar hours, Olex can
calculate future ocean currents.
The ocean is divided into a grid, similar to the depth boxes,
but with a slightly coarser resolution.
Each square - current box, contains a set of observations
related to the timing of the lunar half day.
In addition to the measured currents at the moment, the
measurements are stored in the current boxes and builds up a
detailed map.
The yellow arrows in the current map shows how the
