Abstract :
Cartographic mapping of the western arm of the great African rift valley near Lake Albert in Northern Uganda using ERS SAR tandem data was performed. Elevation information were generated from the interferometric SAR (InSAR) data and height values in the range of 540 m to 610 m deep were measured along the 42 km long depression region identified in the SAR image. The results do quite agree with reported data in the geographic literature
