Installation

Installation from last year is being used. Basically the install is sandboxed into /opt/mapnik to avoid conflicts with other applications. Details can be seen at: http://svn.osgeo.org/osgeo/foss4g/benchmarking/mapnik/scripts/install_mapnik_rhel_5.5.sh

Indexing shapefiles

I simply used the default depth of 8 (which is what is used if no options are specified) to the mapnik `shapeindex` tool.

   sudo chmod -R g+w /benchmarking/wms/2011/data/vector/osm_base_data/data/
   rm /benchmarking/wms/2011/data/vector/osm_base_data/data/*index
   shapeindex /benchmarking/wms/2011/data/vector/osm_base_data/data/*shp
