Site suitability analysis for urban development using GIS based multicriteria evaluation technique: a case study in Chikodi Taluk, Belagavi District, Karnataka, India

摘要

Determination of appropriate site location for urban development is critical issue in hilly areas. The present study aims the Geographic Information System (GIS) and Multicriteria Evaluation Technique (MCE) based site selection for urban development in Chikodi taluk, Belagavi district, Karnataka. In this study six thematic layers were considered such as slope, land use/land cover, road proximity, land value, lineaments and aspect, the generated thematic maps of these criteria were standardized using pair wise comparison matrix known as Analytical Hierarchy Process (AHP). A weight for each criterion was given by comparing them with each other according to their importance and all the six maps were converted into raster. Finally with the help of these weights all the six maps were integrated and overlaid for the preparation of site suitability map for the urban development. The final site suitability map was divided into five different suitability categories. The area under very low, low, moderate, high and very high lands stand at 1.81 km ~2, 12.71 km~2, 37.94 km~2, 66.88 km~2, and 22.44 km~2 respectively. The present study allows the local people as well as planners for the appropriate plans of land use planning in sustainable urban development.
