Well, i think i can do
that. It will work, somehow, so stay tuned for
the Hamburg Openguide in January.
about location information for non-UK cities?
It's not done yet, but you knew that already or you wouldn't have
I am not very good at perl programming, so i think i can't help very
asked. You can use Locales, and you can use the map
address, etc fields - but not the OS X/OS Y fields. Now I can give
you different fields - for latitude/longitude, or if your city is
covered by a square grid like the British National Grid, boxes for
those co-ordinates. Then the problem is one of *using* the data.
It is quite
common to use so-called "Gauss-Krueger Coordinates", these
are printed on official maps (they are NOT printed onto the Falkplan
(Falkplan is for Hamburg what A-Z is for London)).
These are long numerals having latitude and longitude coded into them.
They are not square coordinates...
There is a quite useful feature: One of germany's mobile phone networks
broadcasts the Gauss-Krueger coordinates of their base stations. So
people wandering around Hamburg making entries for the guide can easily
read location coordinates from their telephone. These are not very
accurate, but better than nothing.
Working out distance between places specified by
longitude may be trickier. There is Geo::Distance on CPAN but
How big is the error
if we just assume the earth to be a plane instead
of a ball? This makes calculation of distances from Latitude/Longitude
Hamburg is approx. 50km across.
