Geomatica
Segmentation, Classification and Feature Extraction.
Easy-to-learn and easy-to-use, the Object Analyst add-on guides you through image segmentation, training site creation, classification (including creating custom rules) and feature extraction. By segmenting images into discrete shapes, boundaries and relationships can be more easily seen and analyzed, leading to new insights and discoveries. Shape manipulation and accuracy assessment are also included, allowing quick image processing and results.
End-to-end interferometric radar processing is in the new InSAR add-on. Each step in the process is designed to be flexible, intuitive, and run independently or in sequence through the Geomatica Python API, with default values to aid automation. Using RadarSat-2 and TerraSar-X, InSAR is suitable for any land subsidence or uplift application and allows time-series analysis for measuring change and rate of change across stacks of images. Interferograms can also be generated from Kompsat-5, Cosmo-Skymed and other sensors.
Fast, Accurate, Model Calculation
With features like automated GCP and tie-point collection, multi-way point selection and the ability to calculate absolute, relative or combined models, Geomatica provides everything you need for fast, accurate results. Image thumbnails and background reference layers make project set-up simple, and our efficient editing tools, image deactivation feature and detailed reporting let you spend less time checking your orthophotos, so you can start your next project sooner.
High Resolution DEM Extraction
Extracting high quality, high resolution Digital Elevation Models from the latest sensors is easier and faster than ever. Work with 100’s or 1,000s of stereo pairs, ingest billions of Lidar points, contour lines and other elevation data to create seamless elevation models at full resolution. Effective smoothing and interpolation removes holes, giving you the complete coverage you need for your orthos and mosaics.
Better Looking Mosaics
Along with automatic color balancing and cutline placement, all the editing tools you need can be found in Geomatica. Get consistently pleasing results thanks to global and local exposure correction, contrast adjustment (sigma), as well as dodging points along cutlines or within images. Our overall workflow and interfaces eliminate the need for post-mosaic editing in other software.
Advanced SAR Capabilities
PCI has a long and rich tradition of developing tools for SAR Sensors, including compact SAR, specific sensor models, polarimetry and now InSAR as well. SAR is a particularly attractive tool for many applications because of its ability to collect fine resolution imagery in all illumination and weather conditions.
Geomatica supports all major commercial sensors and many others as well. We work closely with data providers so you can rely on timely support for any new commercial platforms. Recent additions and improvements include PlanetScope, TelEOS-1 and ZY-3, with atmospheric correction support for Sentinel-2, CBERS-4, THEOS and more than thirty others.
Geomatica Developer Edition
The Geomatica Developer Edition is built on our powerful, modular platform designed to exist at the core of your geospatial business. GDE provides developers with full access to hundreds of processing functions, optimized for performance and accuracy, so you can design geospatial applications for yourself, your team and your world.

GXL
Flight Simulation Mosaics

Producing professional, seamless and realistic looking 3D landscapes using commercially available imagery is important for flight training and simulation. Several commercial satellite sensors such as WorldView, Pleaides, and SPOT can provide stereo imagery for high resolution Digital Surface Model (DSM) extraction and very high quality ortho production. Using GXL, large blocks of images can be processed to produce DSMs and seamless colour balanced mosaics that can be draped over elevation models covering large areas. GXL also supports processing for high resolution aerial imagery. L3 Link Simulation & Training uses GXL on a regular basis for their flight simulator scenery creation, training pilots for the F-22, F-16, F-18 and other fixed and rotary wing aircraft.
GXL Flight SimulationDigital Surface Model and High Resolution imagery drape over the Alps, produced using a high volume GXL production system.
GXL now includes two state-of-the-art DEM Extraction algorithms with the addition of semi-global matching (SGM). The new method provides substantial improvement in detail, especially buildings, collected using high-resolution, sub-meter satellites and aerial systems. SGM provides better results in difficult extraction areas, reducing the needs for follow-on editing and quality control.
ADS Processing
ADS 40/80/100 processing is available in GXL, including model calculation, multi-band orthorectification and automatic mosaicking. ADS owners can now take advantage of GXL speed, productivity and editing benefits or integrate ADS into their current frame-based processes.
Massive Country Mosaics
Creating a country mosaic from over 50,000 available images over the country of Mexico presented many challenges to a Mexican Environmental Organization known as CONABIO. That is, until they were able to leverage the power of the GXL Production system to narrow the choice down to the best 4,500 images based on seasonality and cloud coverage, and iterative processing to arrive at the best possible result. This 12.5 terabyte mosaic of Mexico is composed of the best RapidEye images from 2011-2014, and was processed using GXL on a production system in Mexico City.
AerialMosaic mex
One Computer, One Weekend
GXL accelerates proven methods and pushes the envelope of possibilities. Learn how, on a single laptop computer, 4,000 large format airphotos were used to create an elevation model and mosaic over the course of only a weekend.
Aerial Mosaic
Multi-Sensor Orthorectification
GXL is multi-sensor capable, including aerial, optical and radar data processing. Learn how the GXL SAR package was used to create a RADARSAT-2 mosaic to identify a wide range of sea states and wind speeds. The resulting mosaic contains five layers of radar results, including total power and calibrated ?0 intensities for various polarizations (i.e. HH, HV, VH and VV).
SAR Ortho
Better Mosaics
GXL's color balancing and cutline methods produce stunning results quickly and automatically, reducing the need for touch-ups and reprocessing. Live DEM and Smart GeoFill tools make any manual editing fast, simple and effective thanks to live previews and automatic blending.
Higher Accuracy
Sophisticated aerial and satellite workflows provide bundle adjustment methods, multi-view GCP collection, DEM extraction and filters, all of which lead to pixel-perfect results. GXL's QA tools allow you to inspect products at chosen processing breakpoints, ensuring you're getting the quality you need.
Greater Productivity
With a web-interface for job management, you can set up custom workflows and monitor them remotely and through email notifications. Automatic load-balancing distributes work across any number of connected nodes, which can be added, removed or paused depending on your current production requirements.

STAX
Image Alignment and Analytics Software

Collecting UAV imagery over the same location can require costly ground control point setting and surveying, and still result in imagery stacks that are slightly misaligned once processed. Ensuring your imagery is accurately aligned is the first and most critical step in performing multi-temporal analytics. With STAX, the alignment process is easy and fully automated. You have the option to supply a reference image of similar resolution with overlapping coverage to align a deep stack of data, or to use one of the images in your stack as a reference. Once you’ve aligned your images, you’ll be able to perform vegetation analysis, produce reports, and accurately measure changes over time.STAX is a simple to use and intuitive workflow based software tool that will guide you through the processing steps required to create imagery stacks. The following are the typical steps in a workflow.
