Ben, fantastic.
But to my mind there's something illogical about this process.
I'll walk through it, see if you can see what I mean...!
(1)
Data at AIS has Q-Line, wherein amongst other things are the latitude, longitude and the radius of influence of the NOTAM data.
(2)
For no good reason, other than software unsuitability, this useful information is not presented to the (web) users of the data
(3)
A.Another, using data provided by NATS/AIS, creates a lookup table to recreate the latitude and longitude of the NOTAM data by parsing the ICAO code information provided
IS IT JUST ME
