To measure spatially continuous snow depth and to validate
these measurements, we used independent state-of-theart
technologies. It is a difficult task to measure multiple,
spatially widely distributed snow depths in high-alpine areas
within a short time span. Several teams were deployed in the
field on the day of the ADS80 data acquisition, guaranteeing
a small temporal offset to the ADS80 imagery because snow
depth can change very quickly under spring conditions.
