Abstract :
Data collected over the Galapagos Islands using the JPL/NASA TOPSAR airborne interferometric radar covered an area in excess of 5000 km2. This paper presents the algorithms used to mosaic the data into a high resolution (10×10 m ground spacing) topographic map of the islands. Also described are the correlation and height error maps which are generated as ancillary products to the topographic map.
