EarthData Holdings, Inc. (Washington, DC, USA), and its affiliate, Horizons, Inc. (Rapid City, South Dakota, USA), the airborne imaging, mapping, and GIS industries, each purchased a Leica ADS40 Airborne Digital Sensor from Leica Geosystems provider of GIS & Mapping. With the purchase of the Leica ADS40, EarthData and Horizons will be propelled into the digital imaging industry. The ADS40 is an all-digital aerial sensor that requires no chemical film processing or scanning. Users can simply collect aerial imagery and return from a flight mission ready to process and archive their digital data. Its innovative three-line scanner principle (capturing imagery looking forwards, backwards and downwards from an aircraft) provides wide area coverage and, aided by four multispectral lines, simultaneously captures multispectral data. The ADS40’s advanced features and design deliver superior photogrammetric accuracy and coverage.
EarthData has achieved successful results with the ADS40 in its pilot-mapping project in White County, Tennessee. The ADS40 was used to obtain aerial photographs to create 1:400 scale maps the state will use for its statewide parcel-mapping program. Horizons anticipate the installation of the ADS40 in their Conquest aircraft in April and plan to begin acquiring digital imagery during the 2003 spring flying season.
