Geocoding and Reverse Geocoding Addresses in QGIS
From CUOSGwiki
Introduction
Geocoding is the computational process by which a text-based, physical address is converted into geographic coordinates, which can be used for a variety of mapping applications. Geocoding requires a reference dataset and a geocoding algorithm, each of which is composed of sub-operations and sub-components that work together to transform physical, input data into numerical, spatial data. Reverse geocoding is the process by which geographic coordinates are converted into a physical address.
