ABSTRACT

This paper goes to provide an overview of various techniques used for change detection of landcover with conventional and object based techniques. Now days, progression in remote sensing technologies has become a great encouragement for the researchers to analyze various changes in landcover to maintain the environmental balance on the earth surface but due to some addressable issues, it is relatively difficult for researchers to choose one most effective technique.Change detection techniques are having various limitations of extent of defining changes, correctness of classification maps to point out the variations and so on. Therefore several methods have been modeled to prove their effectiveness and accurateness in context of change detection. This paper starts with illustration of prime issues in change detection procedure; review the elementary techniques of change detection followed by the recent object oriented methods for change analysis. Study highlighted the technical soundness of the demonstrated approaches.
