31-Hydrological land use Vegetal cover mapping and change detection through Landsat MSS imageries - A case study of Saharanpur district.

Abstract

For an optimum and better planning and management of 'natural resources one of the first requirements is the Land Use/Vegetal cover map of the concerned area. Most obviously the hydrological land use map at an unit of dis- trict level is the pre-requisite for water resources manage- ment. As the area into consideration for such theme maps is ,usually of an order of several hundred square kilometers, the space technology of polar orbiting solar synchronous satellite-vi-z. Remote Sensing Satellites- plays a significant and vital role. Due to their capability of temporal, repe- titive, multi-spectral synoptic coverage, the Image acquired by various sensors on-board these satellites become very good inputs for Land Use/Vegetal cover and change detection theme-maps. The present paper describes the theme maps of hydrological Land Use/Vegetal cover and change detection in such cover over a period of five years between 1972 and 1977, in the Saharanpur district of Western Uttar Pradesh The Multispectral Imageries of LANDSAT satellite of December 1972 and November 1977 have been used to prepare these theme-maps. Together with these theme-maps paper presents the percentage change in various classes of land cover over the period of study.
