The 5 foot contours are overkill, and will be halved at least for the next edition of the map. It will also be expanded. The northeast part has most of the traditional San Francisco tourist neighborhoods and destinations.

Hi Rex -- Can you elaborate on how you got the contours into OCAD? (Are you using OCAD?) I've stalled on a side-project where I was trying to get GeoPDF data into OCAD...
I like your simplified legend.

They were really hard to see against the olive-green, and the precision was unnecessary given that most of that was covered by buildings. Increasing the contour interval will make it a lot clearer.
Discussing it with some other people, there was some confusion about the roads with black lines running down them. I didn't have trouble, but I'm familiar with the area.
I was wishing I'd had my thumb compass with the magnifier; I missed some stairways at Fort Mason and Ghirardelli Square. (controls J and N) That's not a criticism; I use it regularly.
It was a lot of fun to run on this map. Thanks, Rex!

Tundra/Desert has the system down for converting datasets to vector contours. I did not render the contours, I just made them fit the map. I can send you the instructions he generated (50 steps or so) when I get on my laptop at the hotel.

If you need me quickly, it's best to email, since I'm currently prone to week+/− work breaks. Rex's 50-step instructions refer to getting contours from a USGS (or another) Digital Elevation Model via tntMIPS; if you already have vector contours, these instructions won't work.
Great map, Rex—sorry I couldn't be there, see work break.
The contours for this map (as well as for Get Lost!!'s 1:25k rogaining maps of San Francisco) are already rendered as contours by the City. We the public don't appear to have access to the underlying DEM, or else I'd have generated a contour interval that's more appropriate. I did delete all but every 4th contour for the Mission Street Scramble. The resulting output looks a bit funny, with many jags, but is usable.
