Freemap update: coastlines, height shading and improved scaling



For anyone who may have been following my Freemap free countryside
mapping website, an updated version is now up with the following new
features since the last release:

- coloured height shading - still a bit experimental as it's a little
slow at some resolutions;

- full coast outline, dynamically generated at high resolutions,
pre-generated image at low resolutions;

- ability to scale right out to an outline map of the UK;

- ability to zoom in by clicking on the map;

- full NASA SRTM contour data for all regions of the UK below 55N, so
any summit below that latitude should be identifiable....

I am also intending to team up with the openstreetmap guys
(openstreetmap.org) who aim to provide a central database of free
mapping data. I intend to contribute my data to their database and keep
Freemap as a client of the data. Note also that I am simplifying the
process of contributing your own data to Freemap; it should in the near
future be much easier just to submit tracklogs.
