Conversions available

Two step conversions
Some conversions such as OSM to MTBO do not have ready made crt files. Using a plain text editor you could create your own crt file perhaps using one of the existing ones as a base.
OSM to MTBO
If using the New Map Wizard to create an MTBO base map, you need to use a 2 stage process as there is no OSM to MTBO crt file.
Create the base map with ISOM 2017 as the target. Then use the Symbol set conversion process to get the base map to ISMTBOM 2017 symbols.
See my post on using the New Map Wizard to create base maps.
International Conference on Orienteering Mapping 2018
Presentations by OCAD Inc Staff
There were two presentations by OCAD Inc staff.
Hubert Klauser’s presentation covered two topics;
- generalising orienteering maps with TPI contours
- using the Check Legibility tool
Gian-Reto Schaad’s presentation was on Semi-automatic Extraction of Near-ground Vegetation from Lidar Data
School map symbols

The IOF Mapping Commission presented their proposals for school orienteering map symbols.
It is interesting to see the variety of symbols currently in use for typical school objects.
Colours for the colour vision impaired
Adrian Uppill was a co-developer of a presentation on Solutions for orienteers with colour vision defects. If the Eureka Orienteers’ permanent orienteering course in Daylesford, VIC completes its funding, Adrian’s work on this topic will be put into practice.
