Abstract :
Because of the uncertainties of orbit parameters and baseline, the accuracy of the DEM derived from SIR-C/XSAR interferometric data is limited. The authors describe the use of SLA (Shuttle Laser Altimeter) data as tie-points to construct a DEM from SIR-C interferometry data. The methods and results using preliminary SLA are reported and discussed
