Welcome to the CompassTA Inc. Software and demo data download portal

CompassData V&V licenses and distributes two data verification and validation software tools: CompassAA™ and CompassTA™. CompassAA compares the image derived coordinates in a geo-referenced image with collected ground control data coordinates of the same location. This simple and easily mastered tool verifies and validates the horizontal accuracy of orthophoto images and its associated data. CompassTA performs a similar process for DEM products and LiDAR data. It compares collected ground control derived heights with the elevations in the DEM at the same location. Both programs easily produce consistent, standardized and professional reports. These data verification and validation reports can be customized for any data quality requirements. The software can produce different types of error statistics (RMSE, CE90, CE95, NSSDA), a circular error plot, histograms for points in CompassTA and can include photos and diagrams of each point used in the analysis.
