ASIAN INSTITUTE OF TECHNOLOGY AT76.9034: GEOSPATIAL DATA PROCESSING HOMEWORK 1 Name of the Instructor: Dr. Apichon Witayangkurn Name of Student: Armaan Jain ID No: st116963 Date of Submission: 19 Jun 2015 GIS APPLICATIONS IN SOLID WASTE MANAGEMENT Background of Study: Solid waste is an unwanted useless solid materials generated from residential, industrial and commercial activities in an area. It may be categorised according to the contents (organic material, glass, metal, plastic, paper); or according to hazard potential (toxic, non-toxic, flammable, radioactive, infectious etc.). It is a wrong substance in a wrong quantity at a wrong place and in a wrong time. Solid waste management became an important issue because of…show more content…
The process of selecting an optimum disposal site in somewhat a complicated process as it involves several parameters such as distance to roads, habitation, infrastructure elements and properties of soil present over there. GIS has found to play a significant role in the process of siting an optimum disposal site for MSW. GIS is a system designed to allow user to collect, manage, analyse, and retrieve large volume of spatially referenced data and associated attribute data collected from a variety of sources. The role of GIS in MSWM is large as many aspects of planning and operations of disposal of waste are highly dependent on the spatial data. GIS can analyse the optimal locations of transfer stations, it can also assist in planning the routes for vehicles transporting the waste to the landfills. By the application of GIS in solid waste management system we can reduce the time and cost of site selection. Many factors must be considered for selecting a disposal site but GIS is known for its ability to manage large volumes of spatial data from different sources. GIS is a good decision support tool for planning waste management. Manual methods used for analysis of many factors are lengthy and tedious work and in some problems it will be difficult to solve them without the aid of computer software, e.g. optimization software,…show more content…
The MSWM is done on the basis of many operations like analysis and many literature reviews of past situations. The proposed system must be suitable for increasing growth in population so, the proposed suggestions for developing the system through GIS based model would reduce the waste management workload to some extent. To select a suitable site for disposal analysis must be done and this analysis requires information in the form of topological map, Land use/ Land cover map, soil cover, water table map and Satellite images of the particular city. The information from all these mediums has to be linked together. As the information is based on the same location, they can be correlated and synced. This will form a complete set of data including both spatial and non-spatial information. So now, suitable sites are to be selected for waste management and data from the existing sites must be studied to select the best suitable site for
