Hi all, it is a wonderful idea to improve FlightGear with satellite image derived textures, SRTM elevation data and a new grafic-engine as Manuel Massing <[EMAIL PROTECTED]> suggested. I use commercial data since a long time (DSat5) for FLY!II and X-Plane but as license agreements forbid giving it to the community I worked with low-res Landsat 7 data (and SRTM elevation data) and developed tools (Win32, Delphi) for improving picture quality, cutting and easy import into FLYII. Low-res satellite textures are an improvement to more reality-feeling but there are big limitations, too. Therefore I made a short demonstration what you can expect from 30m/pix (Bremen/Bremerhaven) and improved 30m/pix (Aosta) Landsat 7 data.
http://www.nord-com.net/vollnhals-bremen/landsat_7.htm These screenshots are rather old and made for other purposes. But you may see the limits of these low-res satellite data. They are good as a very realistic background but you loose important landmarks (smaller streets, railway-tracks, smaller rivers ..). As the actual FlightGear scenery is not bad for VFR flights (low altitude) I would suggest that low-res satellite pics could serve as some background-texture with high reality effect and some of the actual data-set (streets, railways, runways, power-lines ...) are drawn on top of the satellite picture (must be synchronized). Combined with SRTM this would be a really great improvement. "HeliFLYer" Georg Vollnhals, Bremen, Germany --- Outgoing mail is certified Virus Free.
