Field campaign at Trollstigen Pilot

A field campaign to Trollstigen was conducted in early July, with the purpose to collect detailed data sets for further work at the Trollstigen pilot.  The Trollstigen Pilot field work campaign was performed by James Strout (NGI), Karlee Isfeld (NGI/NTNU), and Sean Salazar (NGI).

The campaign focused on remote sensing methods, specifically terrestrial LIDAR scanning and the use of GigaPixel photography.   These data sets provide detailed topographical information needed for high-resolution terrain models, and for applications in change detection for monitoring mass movements.  Karlee will continue with post-processing and analysis using the LIDAR data in her autumn project and subsequent Masters thesis.

GigaPixel photography is essentially a composite photograph made of many (100+) high quality SLR photos taken in a matrix format.  The composite image can be used for safe, cost effective mitigation performance follow-up as well as for studying geological features and planning mitigation measures.  For an example image of Trollstigen, please visit Trollstigen, station 2 full panorama (gigapan.com). Pan and zoom in the image to see the level of detail possible using this technique.

SVV is planning additional survey activities using drone-based LIDAR in connection with other research projects, hopefully this drone-based data will also be made available within Klima2050.
