Actually, because its longitude/latitude on the curved surface of our
lovely planet, its actually slightly more complicated!

That said, if you're just doing the UK, then you can probably get a close
enough answer for your purposes by approximating longitudes and latitudes
to being X-Y coordinates on a flat surface. We aren't that large a country
after all!
However you would need to put a scaling factor in to map n degrees of
longitude/latitude to approximate numbers of metres. Because the UK is not
at the equator, 1 degree of longitude is going to be a shorter distance (I
think thats correct?) than one degree of latitude.

would also be helpful to others if you posted a link to the updated
location
mappings with lat/long after you parse the feeds.

Unless the locations change, then you only need to do it once. Or if

do, then you shouldn't have to renew it very often.
