This document is a presentation about advanced cartographic map rendering in GeoServer. It discusses GeoSolutions, an example map, raster styling techniques like hillshading, scale dependent rules, hatches and patterns, point symbology, labeling, transformations, and cross-layer filtering. It provides code examples and links to demonstration maps and data.

- 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. 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. Scale dependent rules FOSS4G 2011, Denver 12th-16th September 2011
- 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. Example FOSS4G 2011, Denver 12th-16th September 2011
- 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. 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
