Abstract

In this research a topography indicator map was produced to show slope and landforms. The process involved the use of appropriate software in the Geographic Information System (GIS) environment.
Different data was collected basically from Shuttle Radar Topography Mission (SRTM) and Global Positioning System(GPS) of the study area, these was integrated in the GIS environment using appropriate software.
The Digital Elevation Model(DEMs) from STRM was preprocessed, data analyzed and then colors were assigned to relevant features to make the map readable. These type of maps produced can be used in Environmental Management, Urban planning, Agriculture and Hydrology.
