  10. 10. Raster styling FOSS4G 2011, Denver12th-16th September 2011
  11. 11. A DEM and a color map SRTM from USGS Standard color map Just avoid the nodata values with opacity=0 A bit dull… FOSS4G 2011, Denver 12th-16th September 2011
  12. 12. Add hillshade GeoServer cannot do hillshade on its own now gdaldem to the rescue: gdaldem hillshade -z 5 -s 111120 srtm_boulder.tiff srtm_boulder_hs.tiff -co tiled=yes Partially transparent FOSS4G 2011, Denver 12th-16th September 2011

  14. 14. Scale dependent rules FOSS4G 2011, Denver 12th-16th September 2011
  15. 15. Scale dependent rules Too often forgotten or little used, yet very important:  Hide layers when too zoomed in (raster/vector example)  Progressively show details  Add more expensive rendering when there are less features Key to any high performance / good looking map FOSS4G 2011, Denver 12th-16th September 2011
  16. 16. Example FOSS4G 2011, Denver12th-16th September 2011
  17. 17. Hide as you zoom in Add a MinScaleDenominator to the rule This will make the layer disappear at 1:75000 (towards 1:1) FOSS4G 2011, Denver 12th-16th September 2011
  18. 18. Alternative rendering Simple rendering at low scale (up to 1:2000) More complex rendering when zoomed in (1:1999 and above) FOSS4G 2011, Denver 12th-16th September 2011
  19. 19. Alternative rendering FOSS4G 2011, Denver 12th-16th September 2011
