Taxiway designations

[Roland Donnell]

Is there a designation standard that establishes the direction in which taxiway lettering begins? For example ADS is south to north and GYI is north to south. I'm thinking it must be based on the location of the control tower. Not sure on non towered fields.

Whoever wrote this obviously doesn't understand how government is supposed to work.
