New Map StandardsISOM 2017 Mapping info
Check out what’s new in mapping standards for 2018.
Includes new symbols to improve map clarity and improve route choice decisions.
Fancy a new map?
The International Orienteering Federation IOF has published new mapping standards. The document is titled ISOM 2017 International Specification for Orienteering Maps. These new specifications will apply to all IOF events from 1st January 2018 and are optional for IOF events from 1st May 2017. Whilst we are not immediately affected, all future PFO maps and updates to maps will be drawn using the new standards and symbol sets.
Most symbols remain unchanged, though some of the rules for their use have. There are a number of new symbols which will help clarify certain features. All dimensions given are for a 1:15000 scale map, therefore at 1:10000 the dimensions are 150% greater and at 1:7500 (non-IOF standard, but commonplace for small areas and young or old age groups) dimensions are 200% greater.
To appraise yourself of what to expect in future, or if you are keen on knowing more about mapping, please download the IOF document linked to above. Read all the intro sections to understand what you should expect from your competition maps.
