Automatic Change detection in Synthetic Aperture Radar satellite images

Source

Source summary

Build a Google Earth Engine tool detecting human-made changes between Sentinel-1 GRD SAR images while filtering natural changes such as flooding, snow and vegetation. Use co-registered images, preferably matching viewing geometry, with user-defined area and adjustable filtering thresholds. Scale to large areas, generate alerts and export georeferenced polygons as shapefile/GeoJSON. Minimising false alarms for human-made change is the stated assessment priority.
