Since GPL allow commercial reuse and only the bathymetry seems to be copyrighted the rest is probably ok to use as long as NASA, or preferably NASA’s Earth Observatory, is given credit. We ask that NASA’s Earth Observatory be given credit for its original materials the only mandatory credit is NASA. The download links get updated regularly with improved releases (Im constantly rebuilding). Add this directory to Additional Scenery Folders in the FlightGear GUI (launcher) If you previously installed ChampaignCustomScenery skip to step 6, as youve already done. The new download link is a proper web page (not a shared Dropbox folder link), and includes an interactive map where you can zoom in and out and click on the areas you want to download. They also provide a significant North-South flight area with NLCD land cover and (optional) photorealistic scenery.

To be fair, since FG is open source it cant use as much scenery data as other sims because of licensing restrictions. x-plane doesnt have places which look really bad like FG. Anything used in Flightgear must be under the GPL. where copyright is indicated, you must obtain the copyright holder’s permission we usually provide links to the organization that holds the copyright, While FG has some great scenery regions it has some bad ones as well. Most aerial photography is not available to be used in Flightgear due to licensing restrictions.Re: Flightgear: Photorealistic Rendering. A lot is yet to be discovered/implemented 18 posts of 2 1, 2.
