What is Geocoding?

Geocoding converts street addresses into approximate geographic coordinates (like latitude and longitude). This process sometimes is also used in reverse (aptly named reverse geocoding), where geographic coordinates are used to approximate street addresses.

Geocoding can be performed by entering a single address. However, sometimes it is desired to process multiple addresses simultaneously. The processing of many addresses into geographic coordinates at once is known as batch geocoding. The terms batch geocoding and bulk geocoding are often used interchangeably to refer to the same process.
