Plotting a route (from relations) on an OSM map
Plasing deur Richard op 14 Desember 2008 in English.We have lots and lots of lovely relations in the OSM database these days (as well as some fairly nasty ones) but they're not always shown on the map of your choice.
So I've just knocked up a very little bit of code to take a route relation, and plot it on a map using OpenLayers. Code here, example here.

Arrgh! You've used the evil piece of GPX code that should really be sent to /dev/null.
Anyway, there's an easier way to do this. Just grab the full OSM file from the API, and add it to OL using the Vector layer + OSM format.

Ha ha. FSVO "easier" maybe. I tried using the proper way to do it - in fact, I spent half the afternoon using GML which should logically be much more flexible than GPX - but the only thing that'd work (in this browser, at least) was said evil piece of GPX code...

A demo, http://ge.pythonmoo.co.uk/maps/osmrelations.htm
Also shows the upcoming method of vector handling in OL, currently broken with reprojectioning stuff. (Tower Hamlets)

I've been looking for something like this, between these two I can now render the Lycian Way relation nicely to make it clearer what's missing.
