Abstract :

The present study analyzes the dynamics of land use / land cover using modern geospatial techniques of Remote Sensing and GIS Yeldurthy Mandal, Medak District, Telangana. The seasonal data of High-resolution satellite data from IRS-P6, LISS-IV –MX Resolution of 5.8m satellite has been used and data collected from field visits were used to analyze the dynamics of land use / land cover of the above area. Erdas and Arc-GIS Softwares were used for classification of land use/land cover. The land use / land cover system is developed based on topomaps and satellite imagery of two seasons (Kharif & Rabi). This classification is of Level-I and Level-II grouped into 6 types based on the classification system. The major land use is Kharif Crop 47.46 Sq.Kms (26.2%), Two Season Crop area 44.83 Sq.Kms (24.7%), Fallow Land 3.31 Sq.Kms (1.8%), Built Up 2.81 Sq.Kms(1.6%), Mine 0.51 Sq.Kms(0.3%), Forest Deciduous 7.41 Sq.Kms(4.1%), Scrub Forest 36.72 Sq.Kms(20.3%), Stony waste 2.29 Sq.Kms(1.3%), Scrub Land Dense 0.88 Sq.Kms (0.5%), Scrub land open 22.06 Sq.Kms(12.2%), Waterbodies 12.96 Sq.Kms(7.1%). The study helps in identifying land use and land cover classes, and the data can be used for future environmental monitoring studies.
