Good game military air base map to convert for GTA 5?

Hello all,

I am hoping I might find some assistance or advice in procuring a high quality Air Force Base map to bring into GTA 5. I have looked at the FSX and other flight sim maps and seen that they are low quality. With GTA 5 being a 1st/3rd person perspective sandbox game the models and textures need to be decent. I am not aware of any other air bases of high quality in other games. Maybe Ace Combat? Has anyone ever ripped a map portion from that game? I have seen vehicles only.

I sincerely thank you for any assistance or advice that you may offer.

Kind regards.
