Managing locations

Hi All

I know this is a strange request, but I currently creating an estate agent
type site and I noticed on somebody else's (big company - not interested in
little old me!!) that they give the user the option to see property results
that are 2, 5, 10 miles, etc away from the location that I can pick.

I think this is a really clever feature, but have a sneaking suspicion that
this kind of effect could be re-created using some kind of internal grid
reference proc rather than having to buy a £30,000 piece of post coding
software.

The locations that I am using are only probably half of 1 county so its not
as if I'm trying to map out the whole of the UK.

Has anybody had a go at making their own internal grid ref system to get
this sort of thing to work?

Rgds

Robbie

The above code may be US-specific, but perhaps you could use it for UK,
given you can figure out the latitude/longitude for given PIN codes.

You can purchase a database containing lat/longs for zip/postal codes. You
could use that to come up with rough geocodes for the locations based on
postal code & then use a bit of geometry to filter the results based on a
radius you choose.

You might also want to check MS MapPoint ... I think they have some
affordable options for geocoding, etc. although I don't know if it's
available for the UK.
