[...] was over 18 months ago that I was originally trying to get hill-shading and hill-colouring working on OpenCycleMap (in fact, it wasn’t even called that back then, but that’s a different [...]

Is there any way to correct SRTM data on the Cycle Map?
The following link, http://www.openstreetmap.org/?lat=38.47166&lon=-109.73651&zoom=15 shows the road going to Dead Horse Point State Park, in southern Utah, near where the shot the movie “Thelma and Louise”.

Unlike what the contours indicate, the road does not go down a 1000 foot cliff, then run level. Actually it runs along the top of the cliff over a 40′ wide “hogback” which drops 1000 feet on either side. It then ends on top of a small 1000′ mesa. The cyclist hoping for a wild vertical ride would be disappointed, but the view from the top is superb.

Altitude data comes from the NASA SRTM project – have a look through the mailing lists or this weblog for more details.

nice! I’m a bit new to OSM where is altitude data recorded? or is this something you are adding to the data from another source?

I’m writing a vector based renderer using silverlight – http://blog.figmentengine.com/search/label/OpenStreetMap so altitude data would be nice to add, mainly for the ahhh! factor

[...] in the area that need mapping. Interestingly (well, maybe only to me) we were in the area of the hill shading teaser that I made a few months ago – staying just off the top, and spending most days walking around [...]

> never mind choosing some colours that are a bit more subtle

Whoops, I fail at reading. Sorry.

This looks lovely. I’m a little scared it’ll make the map harder to parse though. A very subtle greyscale might be better: cyclists only really care about local gradient, not absolute heights, so a full-on rainbow height map might be overkill.

Will cycleway=* be rendered as routes (/hazards) in urban areas?

Awesome. Unbelievably awesome.

And that’s a _lovely_ stretch of NCN 8 to choose – some good footpath mapping in the area, too. Though I might ask for one of your popup warning triangles saying “if you’re cycling this bit at night, watch out for the handlebar-height barrier across the path right at the bottom of the hill”.
