Using the final accepted AT results, the stereo image pairs will be oriented to allow further processing for feature extraction. The whole set of image pairs will be allotted to two separate teams. Our advanced photogrammetry suite enables us to capture data from small, medium and large scale stereo models and prepare digital topographic maps (topo maps) with high quality and efficiency. SBL provides accurate digital planimetric feature extraction for cartography mapping and 3D topo mapping in industry accepted standard formats. SBL relies on a project specific process designed to deliver high quality output at competitive prices and quick turnaround time.
