CCD MAP™ Automated CCD Mosaic System

Vexcel’s CCD Map™ is a fully operational and highly automated system integrated in Vexcel’s Apex™ environment that provides coherent change detection (CCD) from data collected by commercial spaceborne SAR sensors that include Radarsat-1, ERS-1/2, Envisat and JERS.

The system automatically ingests and processes (image formation, interferometry and orthorectification) SAR data. The resulting CCD and two-color multi-view (2CMV) mosaic products are automatically archived in standard GIS formats (GeoTIFF and Shape file), available for quick and easy retrieval.

The reference (left) and secondary (center) SAR images show barely perceptible change in surface backscatter, however the coherence image (right) shows a distinct line of change along a political boundary line.
