Geocoding with Google

I’ve been working on a project using the Google maps API recently. I’ve been using it to return the latitude and longtitude of an address and then comparing it against a geo-coded file in a database.

The Google maps API is pretty extensive and fairly easy to use. However, there are some things that you need to be aware of. The first thing is that Google does not want you to use the GClientGeocoder object to geo-code large files. If you want to do that, they want you to sign-up for an enterprise version of the geo-coder, and the cost is an astounding $10,000!

More on that in a later post. For now, here’s a map to play with…

As, you can see, it’s pretty easy to insert a map. You need to get an API key from here. Once you have that, you’re pretty much up and running.

I’ll post some more on the API later and show you some AJAX code that returns the latitude and longtitude results back to the server side for processing.
