Abstract
Photographic images are remotely sensed information of the Earth obtained from above and have been recorded since the late 19th century, initially by cameras attached to balloons, kites, or pigeons. This remotely sensed information has been used for economic analysis since at least the 1930s. It is accepted and proven that Earth observation information gathered from spacecraft provides substantial benefits supporting economic development and supports informed policy and decision making. This paper focuses on the use of satellite data sets (such as satellite images and Shuttle Radar Topographic Mission SRTM data) as a decision support tool in environmental management in the Federal polytechnic Ilaro (FPI). A digital map of the school was obtained from the Surveying and Geoinformatics department. A 20m resolution Landsat 8 satellite image was used as an overlay to vectorize and update the existing topographic details of the school. Shuttle Radar Topographic Mission (SRTM 30m resolution) data was used in Surfer 10 and ArcScene to delineate the topographic configuration of the school. The updated digital map and the produced surface topography will support engineering design, hydrological analysis (such as run off water, flow direction etc.), drainage as well as physical environmental planning for the school. The results shows that manipulation of SRTM data and map update from satellite data using ArcGIS ArcScene and Golden Surfer surface modelling software cannot be over-emphasized as decision support tools in the physical planning processes of a built environment.
