For national cartography, is there an international standard for symbology?
Mapping Center Answer:
For INTERNATIONAL standards, ISO TC211, the committee developing international standards for geographic information, does not have any symbol standards. The only international standards for symbols are for specific information communities – not national agencies – Examples are International Hydrographic Organization's S-100 for nautical navigation charts or the NATO military symbols standards, etc.
For NATIONAL standards, it would be more accurate to say that there are standards for particular types of maps from particular agencies -- like a USGS topographic quadrangle at at a scale of 1:24,000 or an OSGB topographic map at a scale of 1:50,000. And there are also some standards that relate to the data that is used on maps, such as the U.S. National Map Accuracy standards or the Canadian Provincial Government standards. But the agencies in each country will have their own definitions of what those standards are.
