We'll use some geocoding services to get answers to the following questions:
What's the latitude and longitude of a given street address? This is called address geocoding or simply geocoding.
Which street address is closest to a given latitude and longitude? This is called reverse geocoding.
There are, of course, many more questions we could ask. We might want to know a route to navigate between two addresses. We might want to know what public transportation choices we have to get from one place to another. For now, we'll limit ourselves to these two essential geocoding questions.
There are many geocoding services available on the World wide web (WWW). There are a number of terms related to geocoding, including geomarketing, geo targeting, geolocation, and geotagging. They're all essentially similar; they depict location-based information. It can take a fair amount of espionage to track down a service with the features we want.
