Application of Remote Sensing Technique and Geographic Information Science for Flood Risk Mapping-A Case Study of the Offinso District, Kumasi-Ghana

Emmanuel Oduro Amoako and Lin Sun

Flood disasters have become a menace affecting the socio-economic, environmental, health and safety of the people living within the offinso district of Ghana-Kumasi. Monitoring and mapping out flood prone areas, assessing the extent of coverage is thus not in existence and this has been a problem for the government and the entire emergency agencies.

However, this literature uses remote sensing and GIS as an emerging tool within the African Region to address and improve the efficiency of flood monitoring, and mapping with reference to offinso District.

A Landsat ETM+ Remote Sensing Data of 2015 acquired through the GLOVIS website at the time of flooding to make a flood risk map with the help of GIS analysis tools and a generated DEM which shows the topography and elevation of the district.
