Abstract

In this study, we compare ALOS World 3D 30m mesh (AW3D30) which is provided free by Japan Aerospace Exploration Agency (JAXA), European Digital Elevation Model (EUDEM) which is provided free by European Environment Agency (EEA) and the DEM created from digitized contours from the 1/50.000 topographic maps of Hellenic Military Geographic Service (HMGS). The vegetation height of a forest environment affects the elevation data of AW3D30 and EU-DEM, with that in mind, we choose to compare the elevation data in forest fire break lines. The two DSMs, AW3D30 and EU-DEM v1.1 published in 2016 and the spatial resolution is 30m for AW3D30 and 25m for EU-DEM. For the DEM we created from the topographic maps we used 20m-pixel size. The statistical parameters of the three DEMs have examined in 149 forest fire break lines of total length 187,955.8 km. The study area is located in Chalkidiki a part of the Region of Central Macedonia in Northern Greece.
