Mapping and Reclamation of Wastelands through Geomatics Technique in Precambrian Terrain of Mysuru District, Karnataka, India

Wastelands are low-quality land from the agricultural point of view, often referred as degraded lands. The development of vast stretches of wastelands is caused by unscientific handling of land resources which causes ecological imbalance. The present work is undertaken to reclaim the wastelands of the study area through hi-tech tools of geomatics. This study aims to map and record the waste and unutilized lands using Survey of India (SoI) toposheets of 1: 50, 000 scale, IRS-1D PAN+LISS-III satellite and Google Earth images through GIS software's with limited Ground Truth Check (GTC). The database provides spatial baseline information in distribution, extent and temporal behavior of wastelands in planning and implementation of developmental reclamation strategies. The final results highlight the specific wasteland categories in Mysuru district using geomatics technique considering the environmental, biophysical and socio-economical factors.
