GIS Based Appraisal of Waste Disposal for Environmental Assessment and Management in Mainland Area of Lagos State, NG

Abstract

An appraisal of Waste disposal for environmental assessment and management in Lagos Mainland of Lagos state using the GIS has been carried out. GIS has been a veritable tool for analyzing, storing, querying, capturing, displaying and managing of Geographic information or data. This paper addressed the usefulness of Geographic information system applications in Waste disposal distribution and in management. The coordinates of the existing waste dump were collected through field survey and a Garmin 78Sc hand held Global positioning system (GPS) receiver was used in the coordinate acquisition. The result of the field observations and analysis showed that the GIS can be used to efficiently monitor waste disposal location, Scheduling of Waste-Bin and this can invariably be used for proper planning in environmental sanitation, assessment and management holistically. This study shows that the use of Geographic Information system cannot be overemphasized in the spatial mapping of solid waste disposal for environmental management and sanitation assessment.
