Is there a difference in the symbol used for a building overhang or pass through and a shelter (like a bus stop or gazebo)?
If the bus stop or the gazebo aren't really big they are usually signed as particular object with a X or a round. For bigger passable building the symbol is the grey color.
Actually, the ISSOM standard specifically calls out covered bus stops as objects that should be mapped using symbol 526.2 (Canopy). On a 1:5000 sprint map, even small stops can be legibly mapped to scale (or very slightly exaggerated). Also note that it's important to use the proper bounding line. The building symbol uses a .14mm bounding line to indicate uncrossable. Canopy uses the 0.07mm width used for other crossable features.
Thanks, that's what I have been doing but I figured I had better make sure.
Presumably if the shelter has solid wall on 3 sides and is open on one, it should use the 0.14 on the three solid sides, and the 0.07 only on the open side, correct?
I would have said solid wall should be mapped as solid wall, so if there is no building on the other side it would need thick black line. Whether you map one wall or three walls would depend on the size...
if you use the 0.40mm impassable wall symbol for the average bus shelter you will just get a big black blob with a tiny grey area next to it - a misleading representation. Mike's idea is probably better - if technically incorrect.
True. I probably wouldn't bother with walls then, if it's so small you're not going to run into it anyway... so .07mm all round. Just don't put a control inside!
