Whenever Census Tract 2010 is changed, Longitude must be changed accordingly.
If Census Tract 2010 is untracted then Longitude must be blank.
If Census Tract 2010 is tracted and a Longitude tracted code is available, (whether through 1) geocoding, 2) linking a tumor with a tracted address, or 3) manual entry of a Longitude value) the available Longitude code should be used.
However, if Census Tract 2010 is tracted but Longitude is not available Longitude should be set to blank.
Beginning with the collection of 2010 Census data (Eureka release 10.2), LONGITUDE is only stored if the CENSUS TRACT CERTAINTY 2010 values is 1 or 2.
