OSGeo map symbol set

Motivation
The OSGeo Cartographic Library and all software projects obviously need a free map symbol set.

Available Material

 * GRASS GUI icons: visual dictionary
 * Free map symbol sets from GFOSS.it: Simboli cartografici: trees, geology, meteorology and north arrows


 * Cartography symbols from GRASS


 * QGIS's symbols


 * GpsDrive and OpenStreetMap maintain a repository of c. hundreds of Point Of Interest (POI) rasterized and SVG symbol icons under a permissive OSS license. Things like "banks" and "hospitals" are very well covered.
