dc.description.abstractDigital Elevation Model (DEM) describes the physical and topographic information of earth’s surface. Today, DEM produced by different methods is successfully utilized in many geospatial applications such as gravimetric geoid determination in geodesy, morphology analysis in geology, topographic map production in cartography etc. As known, every year, the new satellites are launched to space and provide the most current information about the earth’s surface with different working principles and different image taking configurations and offer this information to end users from large variety disciplines. SRTM (Shuttle Radar Topography Mission) and ASTER (Advanced Space-based Thermal Emission and Reflection Radiometer) are among these methods. ASTER has high resolution and superimposed image with Terra platform. SRTM aims to create a high resolution DEM of 80% of the Earth surface from radar images taken by Space Shuttle Endeavour. In this study, SRTM and ASTER DEM at one-arc second resolution are compared with local heights obtained from GPS-levelling data and accuracies of both DEMs are investigated in the territory of Turkey. The numerical results show that SRTM DEM gives better statics than ASTER DEM with respect to the local height data. © SGEM 2017. All Rights Reserved.en_US

dc.description.sponsorshipShuttle Radar Topography mission (SRTM) is a joint project between US National Geographic Intelligence Agency (NGIA), German and Italian Space agencies under the leadership of the American National Aeronautics and Space Administration (NASA). The aim of the project is to create a high-resolution Digital Elevation Model of 80% of the world's surface (area between 60 degrees north and 50 degrees south latitudes) from radar images taken with the aid of a space shuttle.en_US
