Step 1: Download Aster data from USGS-Earth Explorer website  Step 2: Open Arc GIS – add downloaded Aster contours file – Merge all the contour shp files into single contour file – Click Geoprocessing tool – use Merge option – add all contour file and save it in the desired place – click ok. Step 3: Set projection to the contour file: Open Arc toolbox – Data management tool – Projections and transformations – Project – Give the input file of contour – set output coordinate system as Projection coordinate system – and click ok. Step 4: Open Arc toolbox – Spatial Analyst Tool – Interpolation tool– Topo to raster – add projection contour file - change field as elevation and set output cell size as 200 and click ok.

Open Arc toolbox – Spatial Ana...

·     Step 1:    Download SRTM data from Open DEM website – Download SRTM contours as Shapefile. ·     Step 2:  Open Arc GIS – add downloaded SRTM contours file – Merge all the contour shp files into single contour file – Click Geoprocessing tool – use Merge option – add all contour file and save it in the desired place – click ok. ·     Step 3:  Set projection to the contour file: Open Arc toolbox – Data management tool – Projections and transformations – Project – Give the input file of contour – set output coordinate system as projected coordinate system – UTM  and click ok.        Step 4:  Open Arc toolbox – Spatial Analyst Tool – Interpolation tool– Topo to raster – add projection contour file - change field as elevation and set output cell size as 200 and click ok.             Step 5:  Export the resulted data and save in the desired...

Watershed Delineation - Any Study Area Water is important life-source of living things and plays an essential role in economic development and augmenting growth of agricultural sector and industrial activities especially in the angle of rapidly increasing population and urbanization. Thus analysis must be carried out on a watershed basis because all these processes are taking place within individual micro-watersheds. Watershed is not simply the hydrological unit but also socio-political-ecological entity which plays crucial role in determining food, social, and economical security and provides life support services to rural people. The above video provides step by step assistance to delineate watershed for any region of interest. Geographic Information System (GIS) is a computer-based tool that analyses and manages spatial data & Digital Elevation Model (DEM) can be used successfully to extract several watershed parameters. Delineat...
