CompassData Inc. Solutions for the Public Sector

If your project requires Ground Control, look no further. CompassData provides complete global coverage, with more than 40,000 photo identifiable Ground Control Points available right now, and more GCPs being collected all the time.

Orthoimagery or orthorectified imagery is aerial or satellite imagery which has been geometrically corrected. Geometric correction, or orthorectification, is necessary to adjust for topographic relief, camera tilt and lens distortion. An orthorectified image is a very accurate representation of the Earth’s surface and allows for the measurement of true distance, exact placement of geographic symbols and precise digitization.

Terrain modeling is a critical foundation to many geospatial applications such as orthoimagery generation and site modeling. CompassData generates high quality terrain models in a variety of formats and from a variety of sources. Our DEMs may be used for orthorectification of satellite imagery, volumetric calculations and relief map generation.

CompassAA™ is a simple, fast, and complete workflow solution to verify the accuracy and quality of orthophotos. This software’s consistent methods and readily understood capabilities benefit the planner, producer, customer, or end user of orthophotos. With → CompassAA™ you can prove you are creating, delivering, buying, or using the ‘best available data’ within minutes.

CompassTA™ automatically tests and verifies the accuracy of elevation data products. CompassTA™ lets you test LiDAR point cloud data, DEM data products, and other raster elevation data. With CompassTA™ you can make sure you are creating, buying, or using elevation data that meet your specifications and mapping needs.

With GeoExpress® compression technology, managing this data can become less problematic. GeoExpress® is the industry-standard geospatial compression software package for creating, viewing and publishing geospatial imagery.
