Here are some key features of "PCI Geomatica":
Automation
Geomatica 2012 delivers intelligent automatic mosaicking that includes automatic detection and removal of image brightness variations, radiometric color balancing between images, and automatic cutline determination to minimize visibility of seams in the mosaic.
The streamlined Manual Mosaicking workflow allows users to manually visualize their mosaic prior to actually running the process.

PCI Modeler
PCI Modeler provides an interactive methodology for the development of both simple and complex workflows.
PCI Modeler provides access to a number of standard operations such as data import and export, as well as most EASI/PACE processing programs.
The batching capabilities of PCI Modeler enables import files, export files, and parameter variations through multiple runs of a model making modeler a much more powerful visual scripting environment.

Advanced Synthetic Aperture Radar (SAR) Analysis
Geomatica 2012 also adds SAR Coherent Change Detection giving users the ability to detect changes using remote sensing.
SAR is a particularly attractive tool for this application, because of its ability to collect fine resolution imagery in all illumination and weather conditions.

DEM Extraction
The Automatic DEM Extraction module allows you to create Digital Elevation Models (DEMs) from stereo airphotos, stereo images and RADAR data.
Image correlation is used to extract matching pixels in two overlapping images and then use the sensor geometry from a computed math model to calculate x, y, and z positions.

support for 150+ formats
Geomatica 2012 utilizes Generic Database (GDB) Technology to directly read and write raster, vector and other information from an extensive list of supported file formats allowing quick and direct access to data.
The list of GDB supported formats is constantly being expanded. As new geospatial formats appear, the GDB is updated by the PCI Geomatics development team.
Many popular formats such as those used by Arc/INFO, ArcGIS, AutoCAD and MicroStation are fully supported.

Functionality Improvements
Geomatica 2012 offers many improvements to basic functionality, which will reduce the number of clicks for common operations and save you time.
These include using the mousewheel for panning and zooming, drag and drop functionality for EASI and Focus, as well as on the fly Image Enhancements.
