Photogrammetry is used in different fields, such as topographic mapping, architecture, engineering, manufacturing, quality control, police investigation, and geology. This technique is employed to combine live action with computer generated imagery in movie post-production.
Orthorectification transforms the central projection of the photograph into an orthogonal view of the ground, thereby removing the distorting effects of tilt and terrain relief. The by-product of orthorectification process is orthoimage or orthophotos. Photogrammetry is the science of making measurements from photographs.The output of photogrammetry is typically a map, drawing or a 3d model of some real-world object or scene. SBLGEOMATICS assures solutions for all standard tasks in a digital photogrammetry and remote sensing services that range from aerial triangulation, DEM/DTM generation and stereo compilation to classification and change detection studies.
