Geocoding - Assigning Coordinates to Records

To display your data on a map, you must first assign X and Y coordinates to each record. One way that
MapInfo Professional assigns these coordinates is by matching geographic information in your database
table to geographic information in another table (referred to as a search table) that already has X and Y
coordinates associated with it.

For example, you want to assign X and Y coordinates to a customer record whose address is 127 Winston
Ave. MapInfo Professional reads that address and looks for a matching address in the search table,
such as a StreetPro table. (This search table already has X and Y coordinates associated with its records.)

When MapInfo Professional matches 127 Winston Ave in your table to 127 Winston Ave in the search
table, it assigns the corresponding X and Y coordinates to your record. The geocoded point becomes
part of your database. You can then view these points by displaying your table in a Map window.
