Turn an address into latitude & longitude coordinates
Geocoding is the process of finding geographical coordinates for an address or place that is in a different format. In our case, we start with a street address and then provide the latitude and longitude that most closely approximates that address. This is useful for plotting addresses on a map to determine voting districts, finding distances from one point to another, or localizing business services and transactions.
Often, people think of geocoding as providing the exact pinpoint location for a house or property. While it is sometimes that accurate, most of the time it is derived from a calculation based on other data, such as street endpoints and house ranges within a certain block. Bottom line: it's pretty darn close, but take your own GPS readings if you're in the precision skydiving business.
