| Abstract/Description: | Digital Elevation Model (DEM) is used to display terrestrial information on map. Moreover, DEMs are often used in geographic information systems (GIS), and serve as a basis for generation of relief map. The present study was conducted to evaluate the google earth (GE) derived DEM with three established open source DEMs such as, shuttle radar topographic mission (SRTM) DEM, advanced space borne thermal emission and reflection radiometer (ASTER) DEM and advanced land observing satellite phased array type l−band synthetic aperture radar (ALOS PALSAR) DEM. The study area of present research is experimental farm, Hawalbagh of the ICAR− Vivekananda Parvatiya Krishi Anusandhan Sansthan (VPKAS), Almora, India which lies in middle Himalayas using online tool (GPS visualizer). The accuracy statistics were evaluated using 100 points in the study area having varying topography with three DEMs such as, SRTM DEM, ASTER DEM and ALOS PALSAR DEM. The result showed that google earth data was positively correlated with all established 2 DEM with r value of 0.88 for SRTM, 0.92 for ALOS PALSAR Dem and 0.83 for ASTER DEM. The result showed that the accuracies for the google earth derived DEM is suitable for hydrological and other water resources modelling. |
