Coordinates are measured from the longitudinal center of the main runway.  If
two main runways cross each other, coordinates are measured from the point of
crossing.  If two or more runways run parallel, measurement is taken from the
runway nearest the control tower.

At the recent ESRI conference, someone asked an interesting question
that I will pose to the net:
 
On aeronautical charts, there is a lat-long location given for
airports.  Where in the airport is that location? Is it the control
tower? Is it the radar? Or somewhere else?
