hi again,
as briefly mentioned on irc we'd like to set up an open guide to san
francisco. i wonder what the oslo people did to de-UK-ify
their openguides
- just delete the OSX and Y fields from their template?
the openguides we ran at etcon not really for geographic purposes i
did fix up to accept UTM and convert back and forth between
lat and long
(and OS numbering is just a UTM coordinate with a digit
missing i learned)
also i was thinking of plugging in a geocoder to generate lat and long
from street addresses - e.g.
http://headmap.org/geocoder/geolookup.cgi -
postcode boundaries being very large here.
is anyone else looking at that, i could try and assemble these changes
into a patch but they were a bit messy and should be config options...
Sounds like I need to pull my finger out and write the Geography::Grid
module I have been meaning to write. I think I've got the tuits to do this in
non-work time at the moment. I should also write this up as a hack once
I've done it.
Ivor.

If something were to appear, I'd be more than happy to work as a testbed.

cool, what will it do, that isn't covered by the crossection of
Geography::NationalGrid and Geo::Coordinates::UTM ... be a nicer API?
I haven't done much to de-anglicanize the Orlando
openguide. I keep
meaning to get a tuit into either implimenting Geo::Distance for the
time being (something better than nothing) or take a stab at the affor
mentioned Geo::Grid hack (I'm not the best at maths).
there's a Geo::Distance for latlong on CPAN too. but it uses the wrong
algorithm for calculating short distances on a sphere. i used it in
mudlondon as a good-enough approximation... perhaps it could be patched.
schuyler wrote up some of this stuff, cosines v haversines etc...
for the san diego stuff we did i just converted everything to utm and did
plain old cartesian distance, which is i guess all right for an openguide
where everything is going to be in the same UTM zone...
