16-20: Pink lines, dashed buildings, two shades of brown? I have literally no idea what it means!
They did try and explain it beforehand: http://bristolorienteering.org.uk/sites/default/fi...
but it was still very confusing as there was unmapped stuff under the flyovers.
No idea why they used the drak brown instead of grey
Using single magenta lines rather than cross-hatching makes sense - as long as you can distinguish them from the course markings...
OK. I guess if there was a standard for this we'd soon understand it.
On early Edinburgh maps I used grey/canopy for what they used dark brown. I was told it was wrong because, it was alleged, you're not allowed to run on top of grey.
Agreed that more purple wouldn't help!
On canopies, ISSOM says: "Small passable parts of buildings which can not easily be crossed by competitors, shall not be represented on the map and shall be closed during the competition." (me neither)
bottom line: 3-D isn't mapable on a single sheet of paper
