We are a dedicated group of professionals who have been in the forefront of the Geospatial industry since 1994. We have long been recognized in the geospatial community as a leading provider of global Ground Control data, able to collect precise ground control information in remote and difficult to access areas to support required image or mapping requirements.
We provide accuracy, standardized deliverables, speed, a global network and excellent customer service!
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.
