Abstract
Mapping Wastelands through Remote Sensing and GIS Techniques: An empty area of land, especially in or near a city, which is not used to grow crops or built on, or used in any way and/or a place, time or situation containing nothing positive or productive, or completely without a particular quality or activity. Different authors have defined wastelands as: Land which is lying unproductive or which is not being utilized to its potential; Land which is incapable of producing material or services of value (Ameri¬can Society of Soil Science);Land which has been abandoned and for which there is no further use (e.g. abandoned quarries or mine spoils); Land which produces less than 20% of economic potential; Land where no greenery can be sustained; Lands which are ecologically unstable, badly eroded and degraded; Land which is neither under forest cover or agricultural cover, or assigned for specific purposes such as national parks or national hydel projects.Over a certain period, both geological and geomorphological processes resulted in the formation of a variety of land systems, such as mountains, hills, valleys, plateaus and plains. This reserach carries out that how the Remote Sensing application activates to identify and mapping the wastelands through GIS over the Vellore district which have high temperature over Tamil Nadu, which leads us to manage our natural resources to derive optimum benefit and create higher awrenwss through a highly reliable information system
