Description
A3 Edge is VisionMap’s all-in-one large-format mapping and oblique camera system that completes your projects in a fraction of the time. Well-known for its incredible productivity, A3 Edge covers vast areas at record speed - collecting up to 1,000 km2 of high resolution imagery per hour. The camera utilizes a unique “sweep” mechanism that provides a wide FOV of up to 106° and a 78,000 x 9,600 pixel footprint - enabling wide flight line spacing, rapid coverage and simultaneous collection of vertical and oblique imagery. Its ability to capture high resolution imagery of rooftops and facades in the same flight makes the A3 Edge ideal for 3D city modeling. The camera’s dual 300 mm focal length telescopes, high resolution sensors and 7.4 um pixel size provide extremely high resolution per altitude, collecting, for example, 10 cm GSD imagery at 11,000 ft. (3,350 m). With a high dynamic range, A3 Edge provides colorful, sharp, high quality imagery. The A3 Edge camera is compact (42 kg) and easy to install on existing manned aircraft. Coupled with the fully-automatic LightSpeed Ground Processing System, A3 Edge provides final photogrammetric products at sub-pixel accuracy, up to five times faster than other commercial systems.
