NAACCR XML: Tumor.latitude




Description
Paired with Longitude [2354], 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
Latitude is a 10- digit numeric field, right justified, with up to six decimal places and an explicit decimal point. The format is x12.345678, where “x” is reserved for a negative sign for locations south of the equator. Latitude north of the equator is positive. 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.
    
    

        

            Correct:
                Latitude: 41. 890833
                    
                
            
        
    
    

        
            
                
            
        
        
            
                Not this:
                    Latitude: 41 deg 53' 27"
