I built GeoSafe as a prototype for the PhilSA Space Business Innovation Challenge in 2025. It uses satellite imagery and terrain data to flag possible landslide risk hotspots.

Trying satellite data for landslide mapping
The calculation combines vegetation change, a moisture indicator called NDWI, and slope. Google Earth Engine handles the satellite data. You can change the weights, compare time periods, and export the map layers.
A few details matter when looking at the results. NDWI doesn’t directly measure soil moisture. The sensor monitoring and AI hybrid display are simulated. This is a prototype for exploring risk indicators, so the map shouldn’t be read as a validated landslide forecast.
