I have a database of US based street addresses for which a client of mine offers their services. I am working on a form that would allow a customer to enter in their zip code or address to see if there is service in their area.
Is there a component or an algorithm "out there" somewhere that I can use as a template?
I have played with GIS and the tiger zips in a previous geolocation project but am not sure this is the best way to go.
Here is one crude approach:
Of course, you can speed things up by some how adding information on the centroid proximity structure or contiguity structure of the polygons so there was less looping needed.
good luck
