Description
A3 Digital Mapping Camera System: Dual CCDs. Two 300mm lenses. Fast compression and storage unit. Dual frequency GPS. Weight 38 kilograms. Dimensions 50cm x 60cm x 60 cm. Frames are exposed in a cross-track direction, providing a FOV of up to 106 degrees. High resolution vertical and oblique images are captured simultaneously. A3 LightSpeed Processing System: PC server. A3 LightSpeed Software. The system solves the Aerial Triangulation and bundle adjustment automatically. Manual geo-referencing may be carried out. Automatic processing of DSM, DTM and orthophoto. A3 Image Processing Workflow: Flight planning. Aerial image acquisition. Download imagery and metadata from the storage unit onto the processing system. Inspection of captured imagery. Combine and index the imagery with post-processed GPS. Aerial triangulation and adjustment to ground control. Preparation of a DTM. Editing or validation of the DTM. Orthophoto creation. Image Tiling. Colour profiling. Quality Assurance. Editing of imagery to produce a homogeneous product.
