—Pin mapping (also know as address matching or geocoding) is the process of assigning map coordinate locations to records in a database. A GIS is capable of doing this by comparing the geographic elements of each feature in the database (e.g., address, city, postal code) to the attributes of each feature in a map layer to find a match. The output of pin mapping is a point layer attributed with all of the data from the input database.
