GeoSilk is a set of icons designed for open source web-based geospatial software. The set is an extension of Mark James's Silk icons—probably the most widely used set of icons on the web—that incorporates metaphors for spatial constructs defined by Jody Garnett's uDig icons. Take a gander at the full set or download it from the SVN repository. GeoSilk is available under a Creative Commons Attribution 3.0 License, meaning anyone may use it for any purpose and make any changes they like.

Metaphors of Spatial Constructs
Common Spatial Tools
GeoSilk provides icons for points, markers, lines, and polygons that expand on the vector and shape icons provided by Silk:
|web processing service||geosilk/server_gear.png|
These elements are used in the construction of new icons and usually represent an verb (i.e., action) or adjective (i.e., additional description). To be consistent with Silk, modifier imagery should be 'harvested' from within the Silk set whenever possible, sized at approx. 9px by 9px, and placed in the lower-right corner of a parent icon. New icons should be placed in the /geosilk directory (/silk should never be modified) and named according to Silk's 'parent_modifier.png' pattern.
