Photogrammetrics

Photogrammetry is the art, science, and technology of obtaining reliable information about physical objects, the environment and terrain, through processes of recording, measuring and interpreting stereoscopic aerial images. Remote sensing is a set of techniques and tools used to gather and process information about an area of land or object without direct physical contact. Photogrammetry and remote sensing in transportation have long been recognized as an efficient and effective method for increasing engineering production at all levels.
