I'm not from US and so don't know much about the CRS/EPSG there. Anyway, when reviewing the FAA 5010 Airport dataset on https://www.faa.gov/airports/airport_safety/airportdata_5010/#5010 (direct download link = https://www.faa.gov/airports/airport_safety/airportdata_5010/menu/nfdcfacilitiesexport.cfm?Region=&District=&State=&County=&City=&Use=&Certification=) I found myself confused about what projection was being used. Can anyone help?
There is a "data dictionary" file that can be downloaded but CRS/EPSG is not included:
- ARPLatitude = Airport reference point latitude (formatted).
- ARPLatitudeS = Airport reference point latitude (seconds).
- ARPLongitude = Airport reference point longitude (formatted).
- ARPLongitudeS = Airport reference point longitude (seconds).
Here is a sample of the lat/long fields being used:
ARPLatitude | ARPLatitudeS | ARPLongitude | ARPLongitudeS 51-53-00.8954N | 186780.8954N | 176-38-32.9277W | 635912.9277W 56-56-19.2870N | 204979.2870N | 154-10-57.2000W | 555057.2000W 60-54-49.7150N | 219289.7150N | 161-29-35.9850W | 581375.9850W 60-54-28.3130N | 219268.3130N | 161-26-06.2780W | 581166.2780W
