I have an early prototype of a new site at
http://63.74.13.145/map1.html which I am still testing. There are only 3 or 4 pages at present and the latest version on my local server has the maps at a more detailed level and the dots changed to red!. It should take about 50 pages to cover the UK Mainland.
I use Mappoint to generate the HTML pages locally and then run a program to read any resultant pages, rewrite the 'live' page, alter the URL's, insert decent ALT tags, build META tags and work out the page navigation.
The whole process will be automatic but does mean that I then ned to upload any changed pages to the live server.
What I would really like to do is to add some Java/Js functionality to allow me to place a dot at a selected position on little side maps which shows the user where he/she is within the UK.
