Simulation of Spatial Concentration of Urban Built-up Lands through GIS and Remote Sensing Techniques: A Study of Mysore City, Karnataka, India

Abstract

The present study is conducted to simulate the spatial concentration of urban built up lands in Mysore City. In order to model the urban concentration, the method of Shannon entropy were utilized which gives degree of compactness or degree of dispersion. The formulae have brought to the Geographical Information System environment. Study used 3 set of remote sensing Landsat data with 11 years temporal resolution such as 1992, 2003 and 2014. The Urban built up land were extracted using the visual image interpretation and supervised classification scheme with set of sample signature file. Then 150m fishnet have created to define an equidistant zones. After all, Landscape metrics of Shannon entropy have computed and the Shannon entropy for the year 1992, 2003 and 2014 showed the value 0.99880, 0.96945 and 0.9437 respectively, which indicates the concentration of Urban built up lands is compacting year to year.
