Semester Offering: August
 

The course aims at providing basic photogrammetry concept, procedure, processing task and its result through project work. Error analysis is also considered and explained with various methods. Students will be trained through the software given in the lab.

 

Photogrammetry, Digital Photogrammetry, Accuracy and Error Analysis.
