Introduction

AfriGIS Geocode-API uses text address input of a geographic feature/(s) to provide the coordinates as latitude and longitude for that feature. At this stage the Geocode-API only consists of forward geocoding – text to coordinates and not reverse geocoding – coordinates to text.

Overview

Making use of AfriGIS Geocode-API applications can match an address to its correct location by converting an address into geographical coordinates. Applications submit an address or a search string containing partial address information. The result is either a single record exactly matching the input, or a set of records ranked by relevance when the input is ambiguous.

Matches an address to its correct location by converting an unstructured address into geographical coordinates.
