Suitable Site Selection for Solid Waste Disposal Points in Tiruchirappalli District Using Remote Sensing and GIS
Authors
Abstract
In India the solid waste generation are 65 million tones in every year. In Tamil Nadu the solid
waste generation are 13422 tonnes per day and Tiruchirappalli district the solid waste generation are 435
MT per day. All the solid wastes are dumped on the land surface which will causes air pollution, water and
soil contamination. In this study on suitable site selection for waste disposal in Tiruchirappalli district.
Application of Geospatial technology (Remote Sensing and GIS) for the selection of suitable site for waste
disposal is based on the overlaying various thematic layers. The thematic layers include drainage, LU/LC
(land use/land cover) geomorphology, geology, lineament, Digital Terrain Model (DTM) and road networks
etc. The various thematic layers are created using ArcGIS software. New thematic map (new site selection)
created based on the various thematic layaers overlayed in the ArcGIS software. ArcGIS software is an
efficient tool for spatial relationship principles of connectivity, contiguity and overlay methods. The results
from this study identified potential sites suitable for wastes disposal.
