Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena
Aerial photogrammetry is technically a subset of remote sensing that primarily involves visible light waves in the electromagnetic spectrum. There are some excellent uses in the near-infrared applications as well. Aerial photography is perhaps the most widely used method for creating geographic databases in forestry and natural resource management.
A 3D mesh is the structural build of a 3D model consisting of polygons. 3D meshes use reference points in X, Y and Z axes to define shapes with height, width and depth.
