Orienteering maps should been drawn according to the International Specification for Orienteering Maps (ISOM). This ensures that different types of terrain around the world are mapped with the same symbols that every orienteer understands.
These specifications are updated from time to time. For example, the specifications for Forest Maps (ISOM 2017) and Sprint Maps (ISSprOM 2019) have recently been revised. Orienteering maps, which were still drawn with symbols of an old specification, can be easily updated to the current specifications in OCAD.
Sometimes it’s tricky to find out which symbol set is the current one or with which symbol set a map was drawn. The wiki page Symbol Set Overview was created for this purpose.
A demonstration how to update a Sprint Map from ISSOM 2007 to ISSprOM 2019 can be seen here.
For many years, a vision of OCAD has been to create a usable orienteering map with just one click.
With the latest OCAD Update we have come a step closer to our vision.
Thanks to freely accessible geodata, excellent maps for Switzerland and Finland can be created with the New Map Wizard. The trend towards freely available geodata can also be observed in other countries and we hope to be able to include these countries in the function as well in near future.
