Ensure that the base object you select has a single column or multiple columns for geographic coordinates such as latitude, longitude, and elevation. The geographic coordinates must be in the signed degrees format and can be in different columns or in a single column separated by a comma or a space. For example, you can have a single column called Geocode with all the geographic coordinates

-23.399437,-52.090904, 203

. Alternatively, you can have 3 columns, latitude with the value

-23.399437

, longitude with the value

-52.090904

, and elevation with the value

203

.

When you specify a geocode radius such as 1000 meters, you can search for records that are within 1000 meters. To use proximity search you need another fuzzy match column such as Person_Name that the

MDM Hub

uses to generate match keys. The

MDM Hub

groups records based on these match keys. The

MDM Hub

then uses the match rule that includes the geocode radius to match records that are within 1000 meters of each other in each of the matched groups.
