UPDATE

Whenever Census Tract 2010 is changed, LATITUDE must be changed accordingly.

If Census Tract 2010 is untracted then LATITUDE must be blank.

If Census Tract 2010 is tracted and a LATITUDE tracted code is available, (whether through 1) geocoding, 2) linking a tumor with a tracted address, or 3) manual entry of a LATITUDE value) the available LATITUDE code should be used.

However, if Census Tract 2010 is tracted but LATITUDE is not available LATITUDE should be set to blank.

Beginning with the collection of 2010 Census data (Eureka release 10.2), LATITUDE is only stored if the CENSUS TRACT CERTAINTY 2010 values is 1 or 2.
