Snow cover mapping is often carried out using optical satellite imagery. In this paper we address the problem of snow mapping of small basins with areas only 10 times the spatial resolution of the sensor using subpixel analysis. This technique is currently being used in several basins in the Spanish Pyrenees and has been developed as part of a snow cover mapping and snowmelt runoff forecasting system which uses snow cover as an input for the Snowmelt Runoff hlodel (SRM).
