In addition to retrieving coordinates from the Geo Service, the location Geo.Role value defines a level with member properties supplying latitude and longitude values. Levels that are tagged with location must also provide two member properties with the exact names of Latitude and Longitude that point to the column in the database which contains these values for the level.
