Introduction

This is the tutorial about adding a shaded relief to your map in Geoserver.

 

Step 0: add your DEM map as GeoTIFF to GeoServer, see this tutorial.

 

Step 1: create a shaded relief

  • Open OSGeo4W Shell
  • Set your path to the directory your DEM map is in. You do this by typing 'cd D:\test' for instance. Now this appears: D:\test>
  • Make use of the gdal library (which comes also together with QGis installation) to generate a DEM. The utility to analyze and visualize DEMs is called gdaldem. Type in the shell:
    gdaldem hillshade input_dem.tif output_hillshade.tif


Step 2: open GeoSever

  • Click on your windows start button. Open your GeoServer folder. There should be four options: Start GeoServer, Stop GeoServer, GeoServer Homepage Geoserver Admin Page. Click on ‘Start Geoserver’.
  • Now go to your GeoServer folder again and click on the ‘Geoserver Admin Page’ and log in.

 

Step 3: create new layer style

  • Go to 'Styles' and 'Add a new style'
  • Name your style, e.g. Hillshade, select the workspace you created for the DEM layer and type this:

  • It is important that the opacity is 0.3 so you can still see your original map underneath your hillshade.
  • Click 'Validate' and 'Submit'.

 

Step 4: create new store and save layer

  • Go to 'Stores' and 'Add a new store'
  • Select 'GeoTIFF' under 'Raster Data Sources'
  • Select your workspace, fill in 'Data Source Name' and for 'URL' select your output_hillshade.tif. Now click 'save' and 'publish' your layer.

 

Step 5: style your layer

  • Go to 'Layers', click on the layer you just created and in the Edit Layer screen click 'Publishing'.
  • Scroll down to 'WMS Settings' and set the 'Default Style' to the hillshade file you just created. 
  • Click 'Save'

 

Step 6: create layer group

  • Go to 'Layer Groups' in the left and 'Add new layer group'
  • Write down the Bounds or 'Generate Bounds' automatically
  • Click 'Add Layer' and select first your DEM layer and then the Hillshade layer, so the hillshade is on top of the DEM layer.
  • Click 'Save'

 

Step 7: view your layer group

  • Go to 'Layer Preview' and press on 'OpenLayers' for you layer group. Now both the hillshade and the DEM should be visible.
