Geomatica Focus - Quick Start

PCI Geomatics -


The purpose of this tutorial is to familiarize you with the Geomatica Toolbar, along with visualization of data while using Geomatica Focus.

All of the data utilized within this tutorial is available for download on our website at:

Once the data installation is complete the default location will be C:\PCI Geomatics\Geomatica Banff\demo.

Starting Geomatica

To start Geomatica, you may select either of the following steps:

  • Double-click the Geomatica desktop icon
  • Launch Geomatica from the Start Menu (Start > All Programs > PCI Geomatics > Geomatica 20XX/Banff > Geomatica)

When you start Geomatica using the desktop icon, the Geomatica Toolbar opens and Focus starts automatically.  All Geomatica applications can either be started from the Geomatica Toolbar itself, or through the Start Menu.

The Geomatica Toolbar

The Geomatica Toolbar provides access to all Geomatica programs.


Each icon (button) on the Geomatica Toolbar will provide access to a specific Geomatica program. These can also be run separately through the Start menu. Below is a breakdown of the specific programs that are accessed through each button:

Focus is the main data visualization environment in Geomatica. Focus includes geospatial processing algorithms, data capture functionality, and information extraction and analysis tools.



OrthoEngine is a complete photogrammetry environment, offering geometric correction, orthorectification, and DEM extraction functionality, as well as 3-D visualization and data extraction environments.

Mosaic Tool


In Geomatica 2018, mosaicking changed from being incorporated in OrthoEngine to being a standalone tool on the Geomatica toolbar. The Mosaic Tool allows the user flexibility to prepare, edit and create a seamless mosaic.



Modeler is a visual scripting environment that provides an interactive methodology for developing, automating, and batch-processing both simple and complex workflows.



EASI is a command-line-based scripting environment that provides workflow development as well as customization functionality.

Chip Manager


The Chip Manager lets you create and manage image chip libraries that are used as ground controls in orthorectification workflows.



FLY! is a visualization tool that renders perspective scenes and interactive ‘fly throughs’ by using imagery and elevation information.



SAR Polarimetry Target Analysis lets you load a polarimetric SAR data set, choose a target selection mode, apply coherent decomposition, and display and save information about a data set in numerical and graphical order.

License Utility (only available when Geomatica is installed as a standalone configuration)


The License Manager provides Geomatica licensing and installation information and options. Standalone dongle-based or dongle-less license files can be applied here.

PCI Geomatics Web Page


Allows user’s access to the PCI Geomatics Web Page where you may learn additional
information about various offerings from PCI.



By selecting the button the Geomatica Toolbar switches from Landscape to Portrait.

Geomatica Focus is designed to work with geospatial data in more than 100 data formats through PCI Geomatics Generic Database (GDB) technology. This format flexibility, combined with a suite of easy-to-use viewing tools, makes Geomatica Focus the perfect environment for viewing spatial data.

A major strength of Focus is its ability to easily view and navigate databases. This section will show you how to open and view image layers, vectors, and attribute data in Focus.


Viewing Image Data in Geomatica Focus

With Geomatica Focus started, you are ready to add data.

To open an image file in Focus:

  1. In the Focus File menu, click Open.  The File Selector window opens.
  2. In the Geomatica program files, locate and open the demo folder.
  3. In the demo folder, select Irvine.pix. Click Open. A Landsat multispectral image of Irvine, California opens in the Focus view area.
  4. Alternately the file can be dragged and dropped from the folder into the Focus work area.

Viewing Vector Data in Geomatica Focus

When a file is loaded into Focus, a default layer is presented in the viewer and listed in the Maps tree. All other layers contained in the same file are listed in the Files tree. It is possible to load any of these layers into the viewer and Maps tree.

To add a layer to the Maps tree:

  1. Click the Files tab. A list of available files and layers are displayed from irvine.pix.
  2. Expand the vector layer list of pix by clicking + icon next to it.
  3. Right-click the Transportation layer and click View on the shortcut menu. The Transportation layer displays in the Map tree as well as in the viewer.

Adjusting Layers in the Current View

In Focus, the Maps tree displays all data layers contained in the View area. You can show or hide the items from the View area by clicking or clearing the check box in the Maps tree next to the item. You can also change the display priority of a layer by dragging it up or down the Maps tree.

To move a layer in the Maps tree:

  1. Click the Maps
  2. Drag the Transportation layer to the bottom of the Maps tree. The transportation vectors move below the imagery and do not display in the View area.
  3. Drag the Transportation layer to the top of the Maps tree. The transportation vectors display in the View area.

Viewing Data Attributes

Attributes are characteristics of geographic features typically stored in tabular format. In Focus, attributes can be viewed and edited using the Attribute Manager.

To open the Attribute Manager:

  1. In the Maps tree, right-click the Transportation layer.
  2. From the shortcut menu, click Attribute Manager. The Attribute Manager opens.

Two attributes are included in the transportation layer. ShapeID is a shape identifier and Attribute is a code indicating road class for each vector segment.

Zoom and Pan Tools


When viewing data in Focus, it is important to be able to navigate the data effectively. The zoom and pan tools allow you to do this quickly and easily.

There are several ways to zoom an image in the Focus viewer. The following zoom tools are located on the Focus toolbar:

  • Zoom to Overview mceclip14.png
  • Zoom Interactive mceclip15.png
  • Zoom Inmceclip16.png
  • Zoom Out mceclip17.png
  • Zoom 1:1 Image Resolution mceclip18.png

To zoom in on an image feature:

  1. Click on an area of interest in the Focus View area.
  2. On the Focus toolbar, click the Zoom to 1:1 Image Resolution button. The image changes to a 1:1 resolution.

The Pan tool mceclip20.png is available when the View area is not at an overview magnification.

To pan across an image:

  1. On the Focus toolbar, click the Pan button.
  2. Drag the image manually to view the desired location.


Image Enhancement in Focus

The Focus toolbar includes commands for quickly enhancing and adjusting the appearance of your images. These enhancements include contrast and brightness adjustments.


The Focus image Enhancements, Contrast and Brightness buttons.
Applying Image Enhancements

The standard Focus image enhancements are Linear, Root, Adaptive, Equalization, and Infrequency. Image enhancements can be automatically applied using the Enhancements menu.

To apply an enhancement to an image layer:

  1. On the Focus toolbar, click the arrow next to the Enhancements button.
  2. Select an enhancement from the Enhancements menu.
  3. Alternately you can click on the Advanced Contrast and Brightness icon and get even finer adjustments for the red, blue and green bands.

Adjusting the Image Contrast and Brightness

Interpreting image data is often made easier by adjusting the image contrast and brightness.

To increase or decrease the image contrast or brightness:

  1. On the Focus toolbar, click the arrow next to the Contrast or Brightness button,
  2. Select Decrease or Increase from the menu, depending on how you want to adjust the image.
  3. Alternately you can click on the Advanced Contrast and Brightness icon and get even finer adjustments for contrast and brightness.
