  1. It’s a Wide World Reflections on IS(S)OM from a non-European perspective Rob Plowright

  2. Description vs proscription • Grammars and dictionaries • Runnability example • ISOM should reflect the practice of the best mappers rather than try to direct it • The best mappers are reacting to the market • Otherwise it quickly loses relevance eg:Speed limits

  3. Scale • Considerable debate over this issue • 2000 ISOM allowed 10000 maps without 150% enlargement for ‘special’ terrain • In ISSOM 2000 10000 and 15000 maps are by definition identical • Contrary to the obvious trend towards smaller areas and greater detail

  4. Better suited for long legs Keeps map size reasonable tradition In many terrains long legs are impossible In Japan large maps are very rare and not necessary Many countries have no such tradition. Better suited to very steep or detailed terrain (ie Japan) Perhaps 125% enlargement 15000 10000 See Tashiro map Conclusion: I want to continue to see 15000 maps, but in some areas or countries 15000 is almost irrelevant. It is time to allow use of 10000 for long races in some circumstances

  5. 20% rule • Before ISOM 2000 • Supposedly to cater for ink drawing variations. • Still relevant given the variations in printing • Useful for allowing better representation of a variety of terrains and features • If used wisely the runner does not notice • Can help improve legibilty

  6. ISSOM • Excellent work developing standards for urban terrain. • Originally sprint seemed to be mostly parks and towns but recently more and more forest • The urban symbols don’t work well in forest terrain

  7. Roads and paths • Too hard to see. • ISSOM has increased contours to .20 but left small paths the same • Major paths very hard to see in steep/green terrain • Unacceptable as it make the competition unfair.

  8. Solution? • Already have a good map standard for forest: ISOM • Already accept the principle of different symbols for urban/nonurban. • So use ISOM symbols (enlarged) in forest terrain

  9. Other points • Different shades/screens of brown for gravel asphalt etc?? • Encourage use of tags on walls in urban terrain to help with slope perception

  10. Conclusions I like the fact that orienteering takes place in diverse terrains AND cultures I like the fact that there are different styles of mapping That is why we have training camps and model events I would like to see a little more flexibility in the application/enforcement of IS(S)OM and respect for different cultures If IS(S)OM is a compromise then it makes sense to allow some compromises in its interpretation
