We are going to let our users add points, polylines and polygons to a map. Are there any international standards for map symbology?

For example for emergency symbols?

The INSPIRE data specifications define some standard styles for portrayal of topographic data (transport network, hydrography, administrative units, etc.). See for example the section "11.Portrayal" of this document for hydrography.

If you are looking for standards for the representation of style, see SLD and GSS.

Dear downvoter. It is good practice to leave a comment to explain why you believe the answer is wrong. (I would say that is because INSPIRE is not an international standard, but an European initiative.) – relet Oct 29 '10 at 8:37
+1 for adding a resources that helpful. the reason I asked is because as a developer I'm used to standards but I have very little knowledge of cartographic standards. – MathiasWestin Oct 29 '10 at 9:07
Yes, INSPIRE is an international standard. It is not a world-wide-universal-OGC-ISO standard, but it is one :-) – julien Oct 29 '10 at 9:47

I recently noticed this project by the GeoVista group that is attempting to standardize map symbology for critical incidents (sponsored by the Department of Homeland Security). They have a few conference papers that should be helpful for standardized emergency symbols.

Note this also is not an international standard, but I would check out the references for the papers as they may have some citations that could suggest a source for international standards.

+1 for a good resource, Mayby there aren't any true international standards? Should change the question to ask for "De facto" standards? – MathiasWestin Oct 29 '10 at 15:28
I'm not knowledgeable enough to know for sure but I don't think I would hold my breath for international standards. But that doesn't mean standards in various forms don't exist. Maybe looking at professional organizations (do any international ones for cartographers exist?) would be a good start. – Andy W Oct 29 '10 at 15:44

On a comical stance... 'emergency symbol library'

links to the map..

Tip: Try an guess the symbols

I agree. That one is exceptionally bad. Build a map with them and you get a nice, cluttered mess, too. – Bill Dollins Oct 29 '10 at 14:35

Work has recently been completed in Canada to create a national standard for emergency mapping point symbologies. In many cases the base symbols were inspired by the Homeland Security Working Group (HSWG) symbols but made more usable with today's technology. The Canadian symbols are in PNG format and in an ESRI symbol palette. For further information refer to:

Thanks for sharing the information with us. – MathiasWestin Jan 11 '11 at 9:44

Yes, I'm currently working on this. (GoogleDocs Spreadsheet) I am directly comparing various international dataset map features Including *Garmin Map Features


*CanVec (Natural Resources Canada)

*GeoScience Australia

*Land Information New Zealand

*Ordnance Survey UK



(and now the Infrastructures Symbology Reference)

*OpenStreetMap (current standard features)
