Abstract

The proposed TOPSAT global topography mission, currently under consideration by NASA and the Italian Space Agency, combines InSAR and laser altimeter instruments in order to produce a high-resolution, digital topographic database for the Earth´s land surfaces (1). The results presented demonstrate significant potential for altimeter-calibrated InSAR measurement of elevations and canopy heights over vegetated landscapes, as could be provided by the TOPSAT mission
