Global Digital Topographic Mapping With Spaceborne Radar Sensor

Abstract

Global land topography is an essential data base required in a wide spectrum of geoscientific studies. Medium resolution (few hundred meters spatial, 10 meters height) data is needed in geophysical studies and topographic corrections of gravity measurements. High resolution (few tens of meters spatial and few meters height) data is an essential element in research and application areas such as geologic mapping, hydrologic modeling, engineering project planning and correction (radiometric and cartographic) of images acquired with multispectral and radar imagers.
