Developing land-use information system for detecting disturbed land-use in part of Akure, Ondo State, Nigeria

Land-use dynamics in Akure South, Ondo State, Nigeria was analyzed using land-use based map of the area with ArcGIS 9.2 software. The land-use map was classified as industrial, commercial, agricultural, residential land-uses, and open space. The selection of land use period covers 10years to identify land use changes over the years. Global Positioning System (GPS) was used for taking the spatial reference points of the study area. Land-Use Information System (LUIS) were created through the generated coordinate data. The results attributes past land-use with higher proportion of 65.2% for agricultural, 3.8 percent for industrial, 1 percent for commercial, while residential and open space have 15 percent respectively. Contrarily, the present land-use situation depicts 3.51% for agricultural activities and 48.79%, 45.6% and 2.1% land areas were occupied by industrial, residential and open space respectively. Generally, the Geo-database created reflects agricultural land-use as rapidly disturbed in expense of industrial, commercial, and residential activities in the study area. It is therefore recommended that; the geo-database created should be regularly up-dated to know what is obtainable in a particular space through a link between geometric and attribute data. This will enable the decision-making bodies to have access to information on each feature under consideration and at the same time improve upon them.
