SINMAP (Stability Index MAPping) is an ArcView extension that implements the computation and mapping of a slope stability index based upon geographic information, primarily digital elevation data.

SINMAP has its theoretical basis in the infinite plane slope stability model with wetness (pore pressures) obtained from a topographically based steady state model of hydrology. Digital elevation model (DEM) methods are used to obtain the necessary input information (slope and specific catchment area).

Parameters are allowed to be uncertain following uniform distributions between specified limits. These may be adjusted (and calibrated) for geographic 'calibration regions' based upon soil, vegetation or geologic data.

The methodology includes an interactive visual calibration that adjusts parameters while referring to observed landslides.
