Hi all,
Is there a WMS layer or other data source for contour lines? I am improving
the outline of the water in a reservoir. I have checked Yahoo! aerials to
see the nominal area of the reservoir and I have chosen a particular contour
line on OSM Cycle Map to trace along with Potlatch. This

pleasing representation of the area

Indeed. Also, ISTR the cycle map

I don't think the SRTM contours are accurate enough to use for tracing
bodies of water - you need to walk the perimeter with a GPS or use aeriel
photos.
They aren't. There's also another source called SRTM Water Body

I can show you SRTM data that shows elevations in the flat plain at all the

I've always wanted to fix up a pole about 6-10ft with a secure GPS mount on
one end, and possibly a harness or neck strap to carry the other end on me.

My GPS accuracy (reported
by the device itself) is at best 4m, but in mountainous regions or in cities
it is 5m or 6m at best, often worse. How accurate is my mouse when I click
on a pixel? Visually I am interpolating the (inaccurate) GPS trace

I'm still tempted to get an RC boat and tape the GPS on top.
Some people are playing with RC planes and GPS + cameras...

Having said that, I have just compared my changes with Google aerials, Google
Maps, and another two mapping providers. They are all different, but mine is
a little high, so I am going to choose the next lowest contour.
If the place is in the UK,

I am interested to get Phiilippine contours in img

No, it uses original SRTM data downloaded directly from NASA's FTP server.

Well, first of all, CycleMap uses the same SRTM data (as far as I know),
so if the license is an issue, this applies to CycleMap too.

Hi,
I have used srtm2osm (all credits to Igor Brejc) to convert srtm data into OSM
contour lines. All tiles are zippes in zip format and the complete world
consumes 61G of disk space. See some example at [1].
I have some questions so far:
