PCI Geomatics Updates Historical Airphoto Processing Workflow

PCI Geomatics, a world leading developer of remote sensing and photogrammetric software and systems, announced that it has updated its Historical Airphoto Processing (HAP) workflow.

The HAP workflow, released to the public in March of 2013, provides a semi-automated means to align, orthorectify, and mosaic digitally scanned airphotos. The system can greatly reduce manual labor, increase throughput, and achieve high accuracy. This update adds a functional and intuitive Graphical User Interface (GUI) to the workflow.

“The strong demand for historical airphoto processing drove the decision to add a user-friendly interface to the HAP system,” said David Piekny, Product Marketing Manager at PCI Geomatics. “The GUI further simplifies the process, allowing more users to take advantage of this technology and unlock their historical archives.”
The HAP workflow uses multi-pass processing and automated ground control and tie point collection.  This  produces an accurate math model that can be used to generate individual orthos or seamless ortho-mosaics from hundreds or thousands of airphotos without camera calibration files. The system is built with PCI’s proven Geomatica technology and can be scaled to meet all requirements for historical airphoto correction.

The HAP workflow corrects imagery to make it usable in GIS and image processing software environments so users can benefit from multi-year image analysis, tracking changes that have occurred across the landscape.

“For decades, access to historical imagery was typically restricted to archives and difficult to access – requiring onsite consultations that consume valuable time and resources,” explained Piekny. “Even in cases where the photos were scanned and cataloged digitally, use in GIS applications was severely limited due to misalignment and scale. HAP changes that, and the update makes it even easier to modernize a complete collection.”
