Dataset
MODIS Geolocation Data Set from the Terra Satellite (MOD03)
Abstract
The MODIS Geolocation Data Set is a Level 1B product which contains geodetic coordinates, ground elevation, and solar and satellite zenith, and azimuth angle for each MODIS 1 km sample. These are determined from spacecraft attitude and orbit, instrument telemetry, and a digital elevation model. The primary purpose of this product is to help further processing the Level 1B calibrated radiances and the Level 2 data sets.
