PCI Geomatics - Version GXL - GeoImaging Accelerator
From Other
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 Features
Purpose-built to process mountains of geospatial imagery, GXL ‘s proprietary algorithms result in a substantial improvement in speed over traditional image-processing techniques.
GXL’s Job Processing System (JPS) give you complete control over your high-volume processing tasks. Add or remove processing nodes when necessary, in real time, as you monitor progress. QA tools offer the flexibility for multiple users allowing you to obtain desired output quality while managing you resources effectively.
Create flawless mosaics from terabytes of data and thousands of images with ease with GXL. Make pixel-perfect output a reality without sacrifice.
Through the use of a building model, PCI's aerial processing software can produce True Ortho imagery – ideal for use in urban areas to eliminate building lean and feature obstruction. Automated methods are applied to the imagery pairs to determine the best possible viewing geometry and inclusion in the final mosaic.
High-quality DEMs are necessary to generate high-quality orthos. GXL includes sophisticated algorithms to create high-quality elevation models on which to build your orthos. Hybrid editing is efficient, fast, and gives an instant preview that allows operators to easily see errors in the underlying DEM, edit them quickly, while updating the ortho on the fly before committing to the full processing.
What is GXL?
Accelerate Your Production
GXL is specifically designed to address industry needs for high levels of automation and production capacity. Proprietary algorithms that harness the power and precision of modern computing hardware deliver enhanced data handling with the accuracy and expedience of automated workflows. The result is a substantial improvement in speed and efficiency over traditional image-processing techniques.

- Pansharp Test Results
Built-in Scalability
The GXL system grows with you, making full use of the computing resources available. Processing nodes can be added and removed as needed, allowing your system to be optimized to your production requirements.
Incredible Results
With GXL, high quality output can be obtained in record time for a variety of satellite and aerial image formats. Production throughput will increase exponentially while maintaining pixel-perfect accuracy and stunning image quality. GXL's QA tools allow you to inspect products at chosen processing breakpoints, allowing you to ensure you're getting the desired output quality.
Detail and Efficiency
GXL 2017 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.
