Five HGI-CGS members of GeoTwinn Work Package 3 attended training course in remote sensing methods from 20^th to 24^th January 2020. HGI-CGS scientists already have some experience in analysing data acquired by remote sensing techniques, such as LiDAR and stereo-photogrammetry, but this was an exceptional opportunity for HGI-CGS scientists to try out the latest technology utilised in the identification and analysis of landslides.

BGS-UKRI has an expertise in a diverse set of remote sensing such as INSAR interferometry and satellite detection of small-scale moves, as well as manipulation of digital elevation models (DEM) and 3D geological models. The trainees were presented with, and had an opportunity to gain first-hand experience in usage and interpretation of data gathered by Optical Satellite Remote Sensing, which entails usage of Sentinel-2 data, received introduction lessons to Radar Remote Sensing (InSAR), as well as application of GeoVisionary in interpretation of landslides and erosional landforms.

The trainees processed Sentinel-2 data and tried out GeoVisionary in order to identify erosional landforms. They gained basic knowledge on Radar Remote Sensing (InSAR) concepts, participated in field training with the usage of landslide pro-forma in SIGMA, which included field verification of landslides identified in previous GeoVisionary session. After receiving an introduction to database structure, they jointly reviewed GeoTwinn Croatian pilot areas data, applied all gained knowledge and interpreted the data in GeoVisionary.

Many thanks to our hosting partners, especially to our trainers: Luke Bateson, Dr Claire Dashwood and Dr Allessandro Novellino for their dedicated guidance and cordial welcome.
