It would be a great addition to the realism of the game if the houses , trees , bushes are added in the close radius of airports . Also , the gaps between taxiways and runways can be filled with grass or something else with which the satellite imagery can be compensated inside the airport.
The buildings , trees grasses will require an extra work to be done around the scenery of the airport.
But again I am not in the airport editing team so I really don’t know the pressure and workload, this is my suggestion which can improve the gameplay to great extents.
