Retrieving the photo-archive to reconstruct Svalbard in 1936
In 1936, the Norwegian government conducted a photographic campaign over Svalbard.
A total of 3300 photos were taken out of a plane, covering roughly 2/3 of Svalbard.
Processing these imagery was labor intensive, hence only a small amount was processed in an analogue fashion. However, we are now at a point where we are able to process extensive collections of images on a single workstation. The student will use a state-of-the-art photogrammetric suite (MicMac). This suite is partly developed at our institute, hence there is a possibility to implement own improvements.
The project covers the digital preparation of the archive, as the imagery is scanned but not calibrated. A first pilot study might consist of the processing of a single flight line, over Brøggerhalvøya, for example. This sensitivity study is needed, because the geometry of the photogrammetric flight is weak, and conditioning might be needed. After this optimization, the quality of the products can be assessed with detailed newer datasets over this peninsula.
Dependent on the interest of the candidate, the subject can go into different directions.
The full campaign can be processed, finally resulting in an island-wide geometric change assessment. Or interpretation of glacier change or other cryospheric landforms can be conducted.
