Learning outcome

The students should have knowledge, understanding and some practical skills related to the orientation of images (taken from airplanes and satellites). This includes knowledge and understanding of the mathematical, optical and photographical basis of photogrammetry, the perspective projection, 3D-transformations and model deformations. Further, knowledge of and an understanding of various types of photogrammetric measurement and digital mapping, through both manual and automated methods, as well as the processing of data for presentation. In addition, practical skills in the use of relevant software. Introductory knowledge of airborne laser scanning is also included.
