Mapping Training in 2010

[Red Adder]

I'm with Mharkey on this, though you might find it hard to get map group to agree to any changes to IOF symbols. You could also try playing with the size of the symbol to see if you can get the tags in (again not an approved approach).

The French are very good at this.

When I was down near Millau on the limestone terrain I ran on some of the best maps I have every run on. The accuracy was amazing. They were no where near ISOM, but better for it. Rock and vegetation detail had infinite symbols which represented what you found when you got there. Must have taken a very very very long time to make the maps though.

1/ Some early maps had contour interval "about 5m".

I thought this was because they had been based on the pre-metric contours (25ft?) which were about 7.5m (I think). So if you kept every other contour and added two in between (to replace one) you got to "about 5m".

Thinking about contour interval reminds me of Devilla - the map states 5m contours, its actually 4m - to help show the detail, but has anyone ever noticed?

Yet elsewhere you claim that maps that aren't produced exactly to specification are by definition C**P.

I suspect most mappers tweak the specifications to some extent in an attempt to overcome specific problems.

Thanks for the clarification on the Woolbeeding map Graeme - I never did spot the place where you had previously claimed that there was a contour junction.

In ancient times - long before the coming of the great OCAD, when an 5 colour map was a thing of wonder and a bit of a treat, HOC had an event with novelty controls - Clent IIRC
One of the descriptions was: Contour, End.

Note the dodgy cartography ------->

I had a control on a contour junction at VWC (former name of WMOC) in Sweden Mind you the dscription was "boulder".

ISSOM and ISOM are different things, hence why they are different things, Neil

Of course but there are still instances where the mapper has to do what he/she feels is best for the competitor and so alters the specifications. Orienteers are more familiar with ISOM so is it such a sin to use an ISOM symbol in ISSOM? Furthermore ISSOM is far from perfect.

As an example was it really intended in ISSOM that competitors would ever run on top of a canopy? The specs certainly give no indication that running on top of a building or canopy should ever happen. Yet many mappers are now using the canopy symbol as a higher level walkway - most notably Ollie's inspired mapping of the Barbican. Incidently the London map also includes the black striped OOB symbol.

I think that there are ocassions where it would be helpful for the competitor to see what was under a permanent OOB screen. Admittedly in most cases this would be because there was a dangerous feature underneath in which case the purple hash could be used as GG pointed out in his very constructive and civil reply.
