About FloodMap

FloodMap shows areas below a user-set water level in meters to illustrate possible flooding, sea-level rise effects, and elevation. It provides color flood and elevation views, a current flood forecast map, 3D flood map and simulation, place search and map-click to get or set elevation, multiple base map styles, and negative values for coastal depth and bathymetry study.

The application does not show current or historic flood levels, only areas below the set elevation, and is stated as not sufficient on its own for flood-risk analysis. Complete and larger views require a FloodMap Pro subscription, and the application is not guaranteed free of bugs or inaccuracies.
