PCI Geomatics Releases GXL 2013
RICHMOND HILL, Ontario, Canada—March 26, 2013: PCI Geomatics, a world-leading developer of remote sensing and photogrammetric software and systems, announced today the release of its GeoImaging Accelerator (GXL) 2013 - the latest version of the company’s proven, high-performance, and scalable image processing solution.
“With this year’s release, we have focused on key areas that will improve the overall workflow and quality of output imagery,” said David Piekny, Product Manager at PCI Geomatics. “GXL 2013 provides new tools that allow users to generate Digital Surface Models from large data sets of hundreds to thousands of stereo pairs, and apply new, innovative 2.5D hybrid editing techniques – users can make changes to their elevation models and inspect the resulting quality of orthos at full resolution, in real time. This approach will greatly reduce the manual adjustments and editing, which are typically required in post-production steps, since errors can be spotted instantly and addressed.”
Other key development areas include a redesigned true-ortho capability, as well as improved automated cutline generation methods that model the presence of features in overlapping imagery (such as buildings, trees, vehicles, etc.) to avoid them, resulting in cleaner, nicer-looking ortho-mosaics.
“We believe ortho-mosaicked products generated by GXL 2013 will significantly reduce overall production timelines and provide substantial cost savings over more traditional methods,” said Brad Schmidt, VP, Sales and Marketing at PCI Geomatics. “GXL 2013 continues our legacy of providing cutting-edge geoimaging technology for both the satellite and aerial image processing markets.”
About GeoImaging Accelerator (GXL)
GXL technology combines high-performance computing with PCI Geomatics expertise to provide significant improvements in automation, speed and efficiency. By optimizing and distributing automated workflows, traditional image-processing is elevated to industrial-strength production.

PCI Geomatics Partners with IAVO to Distribute 3D Feature Extraction Software
RICHMOND HILL, Ontario, Canada—June 27, 2013:PCI Geomatics, a world leading developer of remote sensing and photogrammetric software and systems, is pleased to announce that it has entered into a partnership with IAVO to distribute its 3D Feature Extract (3DFE) software.
3DFE provides users the ability to model 3D features in a 2D environment, by calculating feature heights and outlines through the use of overlapping satellite or aerial imagery. The software has been developed by leading scientists at IAVO (International Association of Virtual Organizations), a research and development company based in Durham, North Carolina.
“3DFE provides users the ability to extract highly accurate textured buildings and other features from stereo imagery, with minimum training”, said Peter Hazlett, Desktop Product Manager at PCI Geomatics. “We are pleased to be working with IAVO, and to provide this 3D mapping technology to the global marketplace.”
“We believe 3DFE offers capabilities aligned tightly with emerging trends in 3D geospatial and feature modeling, and we anticipate the software being enthusiastically embraced by PCI’s various user communities”, added Dr. Matthew Heric, Chief Executive Officer at IAVO.
“Building models are expensive to generate or purchase from traditional sources”, said David Piekny, Solutions Product Manager at PCI Geomatics. “Using 3DFE, our customers can easily produce building footprints, extrude 3D buildings, and also derive building texture information, all through the use of their existing stereo data collections. The software provides highly accurate results, is intuitive and simple to use, and will provide increased production speeds for true ortho projects”.
PCI Geomatics will act as the global distributor for the software, with additional distribution to be implemented through its international reseller network. For sales related inquiries or any additional information regarding 3DFE, please contact us at: info@pcigeomatics.comAbout PCI Geomatics
