In the history of Airport GIS and aviation mapping services, CompassData is only the second company to be granted a FAA Letter of Acceptance (LOA0006DE, April 1, 2014) from the Denver ACO. The LOA is based on our ability to provide highly accurate airport GNSS survey and to verify the accuracy of airport orthoimagery that is used for Airport Mapping Databases (AMDB). This LOA is a statement of confidence in our ability to meet AC 20-153A and RTCA / DO-200A standards for production of aeronautical databases. Please see the Press Releases: FAA DO-200A Certification PR V7 and ISO 9001 2015 Certification PR
Crucial Airport and Aviation GNSS/GIS to Meet Compliance Standards

CompassData meets stringent standards developed by the FAA to assure the quality of data used in the preparation of aeronautical mapping, navigation, and situational awareness products and systems. Prior to certification, CompassData completed a rigorous examination procedure in which the FAA reviewed every step in the firm’s methodologies for collecting, processing, and managing GNSS-surveyed ground control to ensure the data is accurate, timely, complete, and traceable. The data provided (GCPs, orthoimagery, and orthoimage accuracy reports) gives the producers of aviation maps such as Airport Mapping Databases (AMDB) assurance that their processes are built on a firm foundation of accurate imagery, increasing their ability to meet regulatory compliance.

What is the foundation of AMDB map generation? A good AMDB starts with a highly accurate digital “orthophoto”. For example, the imagery CompassData typically verifies will meet an accuracy of 0.85 meters RMSE or better; using this imagery, a skilled operator can capture the AMDB features in a GIS system to an accuracy of 1 meter.
It takes very accurate GCPs, an accurate DEM, and industry best practices and software to create the foundation ortho image. These are all processes CompassData is highly versed in, and can tailor to your airport mapping needs. We currently have a growing archive of 325 airport foundation images ready for resale. CompassData is also a DigitalGlobe reseller; we can purchase at discount images from DGs five different sensors and pass the savings on to you.
