Hi, A couple of years ago I sent a mail to lv-ab (a sister mailing-list to this one - which I also lurk on), asking some questions about how to work out distance between two lat/long points on the Earth's surface. A whole flurry of very helpful replies came back, telling me about the Great Circle route and how to calculate it etc. Anyway, this sparked an interest, and we're now going live on a new location-based search engine, called A2B, which should be of interest to navigation-aware people: http://www.a2b.cc Free GPS software which allows you to upload your current position from your GPS device (if you've also got an Internet connection), and a site which allows you to search for the sites nearest to your position, returning their distance and (rounded to compass point) bearing. You can also add your own sites (or someone else's). Anyway, it's just going into early beta-testing and we'd really appreciate some feedback (preferably in our forum at http://forum.a2b.cc although here or elsewhere would be fine too) -- Sam Critchley
