I hope you find a Solution to Implement the Taxiways into your System cause Little Navmap and FS Flight Control grab this Data also to their Databases without running the Simulator.
I for now run Little NavMap on my RemoteMachine in the Background to have the Taxiways on the Airport.
Their is an second Issue i found as a permanently Onlineflyer on IVAO.
Why you not show the IVAO-Traffic on Ground?
It only shows the Aircrafts on Runways when the Transponder is set to on.
There is no Way to find a possible Parking Position, to Start from, if you not see the occupied Positions before.
Solution for now also Little NavMap.
