1. What is Photogrammetry
Photogrammetry is the technique of measuring objects (2D or 3D)
from photo-grammes. We say commonly photographs, but it may be also
imagery stored electronically on tape or disk taken by video or CCD
cameras or radiation sensors such as scanners.
The results can be:
- coordinates of the required object-points
- topographical and thematical maps
- and rectified photographs (orthophoto).
