#6 Multi-epoch historical image processing in MicMac (half day – afternoon)

Historical images are a valuable source of information in analyzing the evolution of landscapes. To be able to fully exploit their potential, the images should be precisely calibrated. However, due to drastic scene changes and poor radiometric quality of the images (1) finding corresponding points between historical images taken at different times remains challenging, and (2) manual ground control point measurements are laboursome or impossible. Consequently, resulting digital surface models are impacted by unmodelled camera systematic errors. 

In this tutorial, we will introduce you to tie-points extraction in multi-epoch historical images in MicMac. We consider historical images as images acquired with analog cameras, however, the pipeline is not limited to historical images. Modern frame cameras, satellite push-broom sensors, or a mix of different cameras can be processed by our pipeline.
