📣📰 Paper alert: Classifying types of gully changes with unoccupied aircraft vehicles 3D multitemporal point clouds for training of satellite data analysis in Northwest Namibia By our former #3DGeo PhD student and #gullydoi.org/10.1002/esp....

Image shows the conceptual explanation for the proposed approach. Types of changes are identified by a humans on the original and on already analysed multitemporal UAV point clouds and tranferred to Sentinel-1 pixel scale to apply pixe-based classification.

By combining the complementary benefits of UAV-based and satellite-based solutions, this work opens a line of research for the study and #classification of surface land dynamics and geomorphological feature extraction in regional extents.
