The IOF has agreed a new mapping specification for standard orienteering events. Over the next few years you will run on a mixture of old (ISOM 2000) and new (ISOM 2017) mapping. The organisers will make it clear what you are going to get at an event. Sprints are covered by a different set of symbols.
Of particular note is the change for a water trough (to a blue asterisk) and a water tank (to a hollow blue square). Also, mappers may use a green dashed line for a vegetation boundary, or the original black dots, but not both on the same map. Other changes are more subtle.

Orienteering Taranaki does not have any changed maps at this stage, but those going to away events may come upon the changes.
