Estimation of Land Surface Temperature of Chilika Lagoon Watershed and its Dependence on Terrain Properties

Abstract

Land Surface Temperature (LST) is very important thing to understand terrestrial thermal behavior, the regional environmental change, and land atmosphere energy balance of a specific geographic area. Landsat Thematic Mapper Thermal Band has high spatial resolution, for this it has significant potency for many applications related to Land Surface Temperature. The rate of evapo-transpiration, rainfall distribution, rate of geomorphic change and distribution of biotic community is directly influenced by land surface temperature. The Chilika lagoon watershed has a unique setup of bare land, Vegetated land and water. Vegetated land and Water cover ratio is 24:62:14 significantly controlling the Distribution of LST of this Lake Watershed. Various land composition reply various response at LST. Using various software and method to build a Basic model, Land Surface Temperature is extracted from the Landsat Thematic Mapper Image. Then the land surface temperatures are compared with in situ Measurements of field survey. Then the result compare with various results of remote sensed data. Land surface temperature image also compared with various terrain types.
