Explore the Google Geocoder Web service that takes a street address and returns data about that address including its longitude and latitude. In this two-part article series, you will combine it with the Google Maps API and XSLT to create data overlays for display in Google Maps and Google Earth. You will create an example application for a real-estate brokerage that lets a broker enter listings for apartments through an HTML form, uses Google's Geocoder Web service to translate those addresses into longitudes and latitude, and then creates KML overlays from the database of apartment listings. In Part 1, you build the first half of the application to collect the apartment listing information from the user, uses the Google Geocoder Web service to turn the street address into its geographical coordinates (longitude and latitude), and stores those coordinates in the database along with the address information.
