摘要：This study focused on the application of GIS as a basis for project planning at a municipal (master plan) level by facilitating an Environmental Planning and Management process in locating permissible areas suitable for natural sewerage pond systems within Shinyanga municipality. The research advances the GIS based method and discusses the basics of Environmental Impact Assessment, including the principles of site selection procedure such as the factors and criteria to be considered in identifying and locating suitable sites for sewerage pond systems. The environmental attributes identified as necessary for the intended application were topography, environmentally protected sensitive areas, existing land uses, and infrastructures. The concerned variables (geographical features) were extracted from several datasets; such as Digital Terrain Model (DTM), topographic maps, control points, land use maps, and high resolution remote sensing images and aerial photographs. The methodology applied involved the designing and implementation of geospatial database for handling environmental data - a GIS based decision support system that facilitated the modeling to identify permissible areas and locate the suitable ones for natural sewerage pond systems.
