Abstract


The Shuttle Radar Topographic mission (SRTM) was carried out in the year 2000 producing a global digital elevation model (DEM). This data is useful for the production of up to date large scale topographic maps save for presence of noise which include buildings and vegetation. This research deals with the removal of this noise and involves processes such as survey field work, and comparison of the corrected SRTM with the existing topographic map of the study area. The study found out that the topographic map produced from the SRTM after the removal of noise did not completely correlate with the reference topographic map obtained from the Ministry of Lands and Survey, Awka. The study recommends that SRTM should not be used for large scale topographic mapping.
