ISOM, ISSOM, ISMTBOM, ISSkiOM symbols & colours
The release of ISOM 2017 symbol templates and colour tables by OCAD Inc has engendered a fair amount of discussion. Mostly to do with why the IOF Mapping Commission decided this or that. However, there have been some queries on the implementation by OCAD Inc.
A few of these resulted in changes that should appear in the next OCAD 12 service update. If you need to be on song now or if you use earlier versions of OCAD, then here are some of those changes. You can thank Michael Wood for his attention to detail and persistence in checking aspects of ISOM 2017 implementation and OCAD inc for their prompt responses.
Note that these changes may well apply to some or all of ISSOM, ISMTBOM, ISSkiOM.
107 Blue colour – earlier ISOMs
In OCAD’s ISOM 2000 colour table, this colour had the overprint ticked which causes it to appear green when overlaid on yellow. ISOM 2017 and other new O ISMs have overprint unticked for the equivalent Blue such as 14 Blue in ISOM 2017. If you have an earlier version of OCAD and are fairly new to orienteering mapping then it may be advisable to check that overprint is unticked for 107 Blue or whatever Blue was used for water line features if you are unsatisfied with how it looks in use.
19 Black colour, ISSOM
This black for passable walls and tramways will change to have overprint turned off. This means it will remain distinct regardless of the colour underneath.
Fence symbol – tags, old OCAD versions
In some much older OCAD versions, the fence symbol tags are the other way. So if converting maps from those older OCAD conversions, it is advisable to check whether the re-orientation of the tags affects clarity of the map in some situations.
301.004 symbol, ISOM 2017
This symbol which has a border will now have an accompanying symbol without border. Michael Wood found that there are occasions where a symbol without border is required;
- where the symbol adjoins an impassable marsh.
- when exporting part of a map, if the edge of a partial area cuts a lake, it creates an artificial border.
- converting lakes without border lines to lakes with border lines may end up with two border lines.

And a reminder about my recent post on converting to ISOM 2017.
