Generation of High Resolution Topographic Maps of the Galapagos Islands Using TOPSAR Data

Data collected over the Galapagos Islands using the JPL/NASA TOPSAR airborne interferometric radar covered an area in excess of 5000 km(sup 2). This paper presents the algorithms used to mosaic the data into a high resolution (10X10 m ground spacing) topographic map of the islands. Also described are the correlation and height maps which are generated as ancillary products to the topographic maps.
