View Pane
The view pane displays the actual loaded data. In this area, you can place the cross-hair
pointer within the loaded data to obtain the position, image values, or vector ID in the
message bar at the bottom of the pane. Information that is displayed depends on the
selected layer in the Maps tree. If a vector layer is selected with the selection tool
enabled, the vector layer name, entity ID, and length is displayed.
For some toolbar functions, the pointer location in the view area controls the image that
is affected. If you have two or more images loaded in the view pane, the top-most
image is affected by any enhancements. Also, if you want to zoom to 1:1 resolution, it is
done based on the visible image and where the pointer is located.
View Modes
In Focus, there are two view modes: Area View Mode and Map View Mode.
The Area View Mode shows data in the full extents of the view pane. In this mode,
no cartographic elements are shown; only the loaded geospatial data is shown.
The Map View Mode shows data as it can be printed. The paper size is controlled by
selecting the map layer in the tree and accessing its properties.
Added cartographic surround elements (for example, scale bars, legends, and north
arrows) are available in Map View Mode only. You can access the Area View Mode at
any time to view data for a particular area rather than the entire map. The
cartographic elements are not available in this mode, but are still active in the
project.
The different view modes let you perform processing and analysis work and create
cartographic output in the same interface.

Secondary View Windows
In Focus, there are two types of secondary viewing windows: Zoom and Clone View.
Zoom Window – creates a second viewer that can show different views of the same
data sets. For example, if you want to zoom in one window and leave the second at
overview zoom level.
Clone View – creates a second viewer in which you can create a completely
different layer.
When the Clone View window is open, a copy of the entire map allows you to reorder
layers and create a different data set.
You can link the pointer in the two windows by clicking the Link Windows button on
the toolbar.
Overview Window
The Overview window is located to the left of the view pane and below the control pane,
and displays a complete overview of the Focus view pane.
The Overview Window shows a smaller version of the image in the Focus view pane with
a bounding outline that you can use to control what is displayed in the view pane. You
can resize the bounding outline and zoom the image.
Status Bar
The status bar at the bottom of the Focus window displays particular values based on
the location of the pointer, including:

Location coordinates – can be any of the following units:
o Paper (mm)

information includes three values for an RGB layer or one value for a grayscale or
pseudo-color layer.
Vector ID –if you use a vector selection mode and select a single vector, the
following information is displayed about that line: layer name, ID number, and line
length. If you select multiple entries, the number of selected lines displays.
Zoom factor – displays the magnification value for the current layer
Approximate Scale Factor – displays a value that is calculated from an assumed
screen size
Hint text – displays information about a button on a toolbar when you point to it
Progress Monitor – displays the progress of long-running processes
These options can be turned on or off by clicking the first arrow in the status bar and

Data Access Tools
Loading Data
Geomatica uses generic database (GDB) technology for reading raster, vector, and
other information directly from an extensive list of supported file formats. Because
no conversion is needed, this technology offers the advantage of quick and direct
access to data and eliminates the need to reproduce files. Data of any bit depth,
size, and resolution can be read into a single window.
Remote Data Wizard
The Remote Data Wizard provides access to any compatible data from an Oracle
database, a Web service (Web Feature Server or Web Map Server), a URL, and
through Open Database Connectivity (ODBC)
The Remote Data Wizard includes a connection manager that saves the connection
information after you have successfully obtained data from the external data source.
It functions like an address book for your established connections
Import ASCII Tables/Points Wizard
You can use the Import ASCII Table/Points Wizard to import and convert tabular
ASCII data. You can format ASCII data the same way as you would with a spread
sheet application. In the wizard, selecting the Delimited option from the Data Format
area lets you specify a formatting character for the table columns. You can either
select a delimiter or specify another delimiter by enabling the Other check box and
identifying the character in the Other box.
The Data Preview area displays an updated version of the information. The wizard
detects delimiters and file formats when you open a text file. When you select the

Fixed Width data format and click the Next button, you can identify the number of
characters in a column of a fixed width formatted file.
Import/Link
The Import utility lets you import GDB-supported formats into a PCIDSK format.
The Link utility protects source data by creating an empty PCIDSK database and
allowing indirect access to imagery on both GDB-supported and PCIDSK files.
Project Files
Focus uses project files, which are a collection of links to data files that refer to how
data from those files is currently viewed, including the order in which the layers
display and any enhancements that have been applied. Project files also save

Selecting the Clipping/Subsetting option lets you create a new subset database from
selected layers and other information sampled from an existing source file.
There are four subset option areas:



Input file selection area – lets you select the subset input file
Available layers area – lets you select the input file layer that you want subset
to the output file. Any number of layers can be subset at once.
Define clip region – lets you select the clip or subset area that you want to use.
You can do this visually by displaying a overview and dragging out a clip size
definition box. You can also type the coordinates in the provided text boxes.
Other clip definition methods include:





Subset-defined coordinates
Subsets based on the extents of a selected file
Subsets based on the extents of a selected layer
Subsets based on a named region
Script subset files
You can also create a script that adds a single file subset to a group of smaller files,
the size of which is determined by the script.
Different reference systems can be used to select a subset area, including:





Raster extents
Geocoded extents
Longitude and latitude extents
Raster offset and size

destination file has to be in a PCIDSK format.
The Translate window consists of three sections:


Source and Destination File selection area – lets you choose the input and
output files by browsing your file system
Format selection – lets you choose from any of the GDB-supported formats. For
a list of supported formats, see the GDB technology technical specification sheet.
Some formats have different options; for example, a TIFF file can be compressed
using any one of five different methods. You can see the available options for the
selected format by clicking the ? button.

Selectable Layers area – lets you select the layers from the input file that you
want in the output file. You can translate any number of layers at once. When a
particular format is selected, only the layers that are applicable to that format are
available from the input list. For example, if you translate from a PCIDSK format
to a Shapefile format, only vector layers are available for the selection.

Charting
Charting is a great way to visualize your data. A chart is a table of attributes
displayed as a graphic where the values of selected records and fields are compared.
It displays quantitative data so you can see how the numbers relate to each other,
which helps you to interpret the information more easily. Trends or anomalies may
become evident when displayed using the right chart type. For example, it may be
difficult to identify trends by looking at a table filled with population statistics, but
with the right chart the pattern become easily discernable.
The Charting functionality in Geomatica Focus includes a wide variety of chart types.






Column charts display the selected data as vertical stripes of different colors or
patterns. The categories are organized along the x-axis (horizontally) and the
values are measured along the y-axis (vertically). Types include:
o Clustered Columns
o Stacked Columns
o 100% Stacked Columns
Bar charts display the selected data as horizontal stripes of different colors or
patterns. In contrast with the column chart type, the values are organized along
the x-axis (horizontally) and the categories are measured along the y-axis
(vertically). Types include:
o Clustered Bar
o Stacked Bar
o 100% Stacked Bar
Line charts display the selected data as lines of different colors or patterns
connecting points at equal intervals. The categories are organized along the xaxis (horizontally) and the values are measured along the y-axis (vertically).
Varieties of Line charts include:
o Basic Line type
o Stacked Line
o 100% Stacked Line
Area charts display the selected data as polygons of different colors or patterns
connecting points at equal intervals. Area types include:
o Basic Area type
o Stacked Area
o 100% Stacked Area
Pie charts are circular graphics which display the data as wedges representing
their portion of the whole. Pie chart varieties include:
o Standard Pie type
o Exploded Pie
Scatter charts are graphs of points comparing two sets of data. One set is
plotted along the x-axis and the other along the y-axis. It is used to uncover a
possible correlation between the data sets, representing their portion of the
whole

ORTHOENGINE
Geomatica Core includes simple geometric correction and mosaicking capabilities
through OrthoEngine. For more advanced orthocorrection and automation, you will need
to purchase additional functionality through PCI’s Geomatica add-on modules.
Polynomial and Thin Plate Spline Math Models
The Polynomial and Thin Plate Spline math models are used to perform geometric
correction on your data. The Polynomial Math Model is a simple math model that uses a
first-through-fifth-order polynomial transformation, which is calculated on twodimensional ground control points and mathematically produces the best fit set of twodimensional GCPs on an image. The Thin Plate Spline Math Model is a simple math
model in which all collected ground control points are used simultaneously to compute a
transformation. The warping is distributed throughout the image with minimum
curvature between the GCPs becoming almost linear away from the GCPs.
Importing Images
You can import GDB-supported satellite images from a CD or digital distribution format
(See the GDB technical specification sheet for more details about supported formats)
Ground Control
OrthoEngine satellite models support GCP and tie-point ground controls.
GCP Collection
