Already Christmas seems not too far away and with it the deadline of 1st Jan 2019 approaches, by which time maps used for all levels of event should be drawn to ISOM 2017.
Many clubs are well on their way to updating their maps to the new specification. You may like to check that the maps that will be used in the New Year have been, or are in the process of being, revised to ISOM 2017. Further details, including some guidance documents, are available on the Mapping Resources page of the BOF website under the heading ISOM 2017. Scroll further down to the British Orienteering Symbol Sets section for details of the ISOM 2017 symbol sets and links to download Symbol Set files.
