Reverse geocoding is the process of converting a location as described by geographic coordinates (latitude, longitude) to a human-readable address or place name. It is the opposite of forward geocoding (often referred to as address geocoding or simply "geocoding"), hence the term reverse.
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]
Reverse geocoding is the process of returning an estimated street address number as it relates to a given coordinate. For example, a user can click on a road centerline theme (thus providing a coordinate) and have information returned that reflects the estimated house number.
Online application to acquire coordinates for any place on Earth. Supports more than 3,000 coordinate systems and 400 datums worldwide. Place pushpins on the map and calculates automatically the coordinates in the selected coordinate system or datum. Perform transformation between coordinate systems and/or datums.
Geocoding and reverse geocoding can be used to convert between locations and addresses. Manual geotagging also introduces possibilities of error, where a photograph's location is incorrectly represented by wrong coordinates.

There have been even more features and access added in each iteration of the SDK, with the latest 3.0 version launching in mid-2015. In the Here Mobile SDK Starter Edition 3.0, there are native Android and iOS APIs for raster tile map display, online points of interest search, geocoding/reverse geocoding and online pedestrian/car route calculation.
A geocoder indexes map data so that users can search it by name and address or look up an address based on a given coordinate pair (reverse geocoding). Several geocoders are designed to index OSM data, including Nominatim (from the Latin, 'by name'), which is built into the official OSM website along with GeoNames.
