This article is part of the QGIS tutorial 2013/14.
In this article you will learn how to pre-process and enhance digital elevation model (DEM) data, as well as how to create a 3D-Model

Loading, merging and reprojection of DEM data

  1. Add the raster layers N51E009.hgt and N51E010.hgt to a new QGIS project (from geodata\raster\DEM, see Course data). Arrange the first above the latter layer.
  2. Merging layers
    • Select Raster --> Miscellaneous --> Merge. In the appearing menu, click the Select in beside the Input files field. Browse for the maps N51E009.hgt and N51E010.hgt and select both (by clicking with pressed Ctrl key).
    • Select an output directory and file name (e.g. N510_merged) under Output file. Confirm with OK.
