Feasibility study for small hydroelectric, power plant projects in Rwanda, Ostafrika
For stereoscopic photogrammetry, aerial image data was processed. With this aerial image data, reliable and highly accurate topographical planning data was created for a feasibility study for small-scale hydropower projects. The resulting digital terrain models and orthophotos form the basis of the planning study. The aerial images have a geometric resolution of approx. 20 cm and a multispectral radiometric resolution (RGB+IR). Compared to conventional measurement procedures, the use of photogrammetry based on aerial images saves both time and money.
