Live from the Ötztal Alps (#2): Exploring high mountain 3D geoinformation

Today was the second day of field work in the Rotmoos valley in the Ötztal Alps for our 16 students. The hot sun challenged the data acquisition but the impressive landscape makes up for every effort.

The terrestrial laser scanning group climbed up the valley flanks to acquire a high resolution point cloud from an end moraine of the Rotmoos glacier from the year 1850.
The electrical resistivity tomography (ERT) group measured a profile along the transition from the valley flank to the valley floor next to the end moraine. The measurement profile was aimed to track the bedrock and to determine the thickness of valley backfilling sediments.
The photogrammetry group took multiple photos from different landforms (e.g. rôches moutonnées and debris cones) in order to perform a 3D reconstruction of these objects. Moreover, the students learned how to set up a real time kinematic global navigation satellite system (RTK GNSS) which is used to survey global coordinates (e.g. of the ERT profile).

For more information about this practical field course read our blog post from yesterday.

We will keep you updated with daily posts – stay tuned.
