One of L3Harris Geospatial’s key customers of the TrueTerrain™ airport operations bundle stack is SLC Associates, a leading provider of aeronautical data and aerodome surveys in over 34 countries. They use the dataset for a variety of activities including internal quality assurance. L3Harris’ products are bundled along with SLC-created surveys and delivered to airport authorities, allowing airports to fulfill their obligations to provide Electronic Terrain and Obstacle Data (eTOD) and ensure safe and efficient operations within the aerodrome.
The creation of TrueTerrain™ airport operations bundle stack products begins with a search for high-resolution optical stereo data over the defined area of interest (AOI). Timeliness of source imagery is essential for providing a current representation of the airport, and when archive data is not recent enough to meet requirements, we work with multiple imagery vendors to task and collect new stereo imagery.
Stereo scenes are triangulated using survey-quality ground control points through triangulation software. The resulting precise registration of the stereo data becomes the basis for geolocation of the TrueTerrain™ airport operations bundle stack.
