I need to be able to enter a zip code and say show me all the zip codes or
towns within X number of miles from that entered one... does anyone know
of a soultion or product that can do this? (can even be $ for the product, a
free example on how to do it would be nice through to learn from) thanks!
Brian,
Can you give me an idea of what you have already?
Do you already have ZIP code and town info? If so, what format?
Points, polygons, etc.? GDT / TeleAtlas, Navteq, Tiger, etc.?
When you say towns, do you mean strictly incorporated areas or MCD/CCD?
If those acronyms and such don't ring a bell, then describe precisely what
you have and what you need.
I ask, because I specialize in stuff like this and have a rather large
framework for dealing with such things.
But there are proly a dozen different results you could be looking for.
Radius from a point, buffer around polygon, etc.
Plus, ZIP code areas can be quite complex things and vary by region around
the USA. They can also be quite different if you are talking about regions
outside the USA.
