Terrain or elevation data is useful for many GIS Analysis and it is often used in maps. QGIS has good terrain processing capabilities built-in. In this tutorial, we will work through the steps to generate various products from elevation data such as contours, hillshade etc. Overview of the taskThe task is to create contours and hillshade map for area around Mt. Everest. Other skills you will learn
Get the dataWe will be working with GMTED2010 dataset from USGS. This data can be downloaded from the USGS Earthexplorer site. is a global terrain dataset that is the newer version of GTOPO30 dataset. Here is how to search and download the revelant data from USGS Earthexplorer.
You will now have a file named GMTED2010N10E060_300.zip. Elevation data is distributed in various raster formats such as ASC, BIL, GeoTiff etc. QGIS supports a wide variety of raster formats via the GDAL library. The GMTED data comes as GeoTiff files which are contained in this zip archive. For convenience, you can download a copy of the data directly from below. GMTED2010N10E060_300.zip Data Source: Procedure
Note The Raster menu in QGIS comes from a core plugin called GdalTools. If you do not see the Raster menu, enable the GdalTools plugin from Plugins ‣ Manage and install plugins ‣ Installed. See Using Plugins for more details.
