@flycanarias:
*Canay islands needs some 3d scenery work, at least the undeveloped airports we've cited before, as more objects in towns and other characteristic areas. Some users here can do that work (for me, let me out sometime to get done other on course projects, please). Take into account since some time ago, the main developer team is trying to get OSM data (buildings, roads, pylons, etc.) to an official form and probably on the next FG versions we can fly through the world with this functionality. I think that improving the Canary Islands at OSM.org will have a positive impact here retrospectively.
*the material files you can read about how to improve the existing or request help experienced users (not my case, sorry).
*photoscenery: you can benefit this type of functionality activating OSGEarth in your system and fly using a photo source. Alternatively, if the source is GPLed you can made a custom pack for FG and distribute it in some form.
Thanks to your support for scenery development in Spain, but i think we need more people or the exsting to be involved to get more things done.
