Elevation Contour Analysis and Water body Extraction for Finding Water   Scarcity Locations using DEM
  The present study was aimed to create new methods for extraction and analysis of land elevation contour lines, automatic extraction of water bodies (river basins and lakes), from the digital elevation models (DEM) of a test area. And extraction of villages which are fell under critical water scarcity regions for agriculture and drinking water with respect to their elevation data and available natural water resources.
