Hi Bob Hughes, you recently wrote in povray.general:

I've been doing a similar project with the registered Moray users and
I've had to write a tool to convert from the real lat/long coordinates
to the ones that I use for the rendering. Turns out the map I'm using
(2048x1024) is a tad inaccurate (error varies up to 2 to 3 degrees
non-linearly), so things now line up pretty nicely. 

I also wrote a program that queries the online database at USGS for
the lat/long of the US cities (don't fancy finding 600 pairs by
hand<g>). 

I'm currently looking for a website that can do lat/long lookup for
non-US cities and that can be queried directly, i.e. with an HTTP
request. No luck so far.
