Hello,
Aerodrome geometric centre coordinates will read: N12 34 56.7890 W12 34 56.7890
Could someone please explain to me what is the difference between geometric coordinates and geographic coordinates?
Thanks,
Georges
In my opinion, Aerodrome is somehow related to airport space use.
Aerodrome Geometric Center. The geographical coordinates of the centre of the runway complex that locates the aerodrome for charting purposes. It is determined by the mean of the latitudes of the furthest north runway threshold and furthest south runway threshold and the mean of the longitudes of the furthest east runway threshold and furthest west runway threshold.
Aerodrome geometric center coordinates is related to airport geometry while geographic coordinates is related to ellipsoid/spheroid.
Regards.
So, I'm thinking that means that one is to use the proper method to find the geometric center of the aerodrome, then determine the geographical coordinates for that point.
In my opinion, yes.

Ohhh... Nice to know.. 🙂
This is sort of fun. I've never tried to translate Philipine/Tagalog. But, I think I am understanding the intent of each phrase above.
In the U.S. this is called the Airport Reference Point (ARP). The NGS method to compute the ARP can be found at -- http://www.ngs.noaa.gov/AERO/arpcomp/arpframe.html
Thanks Dave - great information / link.
