This study examines the application of Geographic Information Systems (GIS) in determining the spatial location and distribution of solid waste dumpsites in Abuja Municipal Area Council (AMAC). This present study applied the Techniques of Geographic Information System (GIS) and Remote Sensing (RS) to dumpsites and selection in the emerging City of AMAC. Spatial data such as land use cover types; road, river and settlement of theCity were extracted from a georeferenced high medium resolution satellite image through on-screen classification using remote sensing software. The existing dumpsites were geo-located and added as a layer to the map of AMAC. The land use cover, settlement, river and roads were buffered at 1000, 1000 and 2000 meters respectively using preset criteria such as distance of dumpsites from a settlement at 1000 m, surface water at 1000 m, roads at 2000 m and absence of important economic or Ecological features; to determine candidate dumpsites from the land-cover types.Majority of dumpsites do not meet criteria for location of dumpsite and many of them are cluster. For the purpose of this work, 6 standard dumpsites were selected for Abuja Municipal Area Council, which is 1000 meter away from settlement to avoid environmental challenge from dumpsite. Remote Sensing and Geographic Information System help in distributing facilities in a real world for spatial phenomena. Therefore, GIS play a significant role in Solid Waste Management System.

Keywords : Land use cover, dumpsite, buffer, remote sensing and GIS.
