How high is your home?
Tap the map or use your location. See how high it is compared with sea level, and what happens when the water rises. Everything is calculated in your own browser; we store nothing.
First choose a place on the map.
Simple estimate from satellite measurements (Copernicus DEM, about ±2 m). Dikes, pumps and how water flows are not included. Check your government's flood maps for the real risk.
Always with you, even offline
In PrepperApp you see this for any place on the map, together with warnings, drinking water, AEDs and your own emergency plan.
And on Our map you add your own meeting point and safe places, readable only by the people you choose.
