NAACCR XML: Tumor.longitude



Description

Paired with Latitude [2352], this represents the point location of the individual’s residence on the earth’s surface. It is typically determined by matching an address to a reference file or by identifying the residence using satellite imagery. This item is coded at the central registry, not by the reporting facility.



Rationale

Latitude and Longitude comprise the universal standard for designating location on the earth’s surface. Geographic Information Systems software can be used to convert these values into projected coordinates for map display. 
Allowable values and format
Longitude is an 11 digit numeric field, right justified, with up to six decimal places and an explicit decimal point. The format is x123.456789, where “x” is reserved for a negative sign for locations west of the Prime Meridian (0 degrees) and east of 180 degrees. The datum of the decimal degree data shall be North American Datum of 1983 (NAD 83).
Values are in decimal degrees, not degrees/minutes/seconds.
Longitude: -123.128943
Longitude: -71 deg 7' 44"
