I have 0.9.10 scenery, which I understood to be more accurate than the previous incarnation. Is it possible that the improvements to accuracy are only evident where the freely available data has been improved? It seems the landcover data is no more accurate than the previous scenery versions (at least in my neighbourhood)... > The solution is to use a better data set or make manual improvements to the > data set we use now. Is there freely available data that will allow such accuracy? I know that in some parts of the world the answer to that is a resounding no...
