From inventory management to underground utility locating, accurate geospatial data has never been more important. AccuEarth has the GIS tools to ensure the accuracy of field data as well as verify the accuracy of any pre-existing geospatial data sets. AccuEarth has access to more Ground Control Points (GCPs) than any other commercial outlet in the world, therefore, we have a unique master database to help facilitate our independent QA/QC.
For verification of the spatial accuracy of aerial and satellite data, GIS layers, or elevation data (such as LiDAR, DEM, etc.), AccuEarth utilizes CompassAA™ and CompassTA™ map accuracy software, developed by our affiliate company CompassData. These verification tools are content enhancement solutions that automate map accuracy verification and eliminate manual processing, ensuring consistent quality control of geospatial products. In addition, AccuEarth is a provider of ground control survey of calibration targets used by satellite imagery providers.
