Things seem to be better, however the final image does not exactly match FG scenery. I tried to export the image with the exact coordinates (when you set DPI, qgis also adapts coordinates accordingly) and then to resize the output image to the wanted resolution, 16kx8k in my case. I think I followed the steps described here, but - to me - it seems the tiles generated with qgis and by following what has been suggested by J-ROME do not perfectly match FlightGear scenery. Moreover, tiles produced the way described here do not really match the coordinates you enter when exporting an image, and this produces a wrong rendering when you fly from one tile to the next one. I use WS3.0 and FG 2020.4.0 git, and it seems the scenery roads and buildings do not match in position with the imagery produced in this example. Unfortunately, I have tried many times, and also by "fine tuning" the parameters suggested in the first message but it seems the tiles produced this way are mismatched from the rest of the scenery. I tried the procedure described here by and, first of all, thank you very much indeed for your suggestions and ideas. Then apply the nvcompress patch from Nathaniel Warner ( nvcompress -bc1a 3105272.png 3105272.dds) (85.3Mo) Project > Import/Export > Export Map to Image.Ģ- apply the coordinate of your tile in this order (N-E-S-W) - in my sample 46 / 9.25 / 45.875 / 9 - others orders may result in a bug (width or height getting above 99999px)ģ- change resolution to 30 dpi ( or whatever which gets you closer to 16384px X 8192px)Ĥ- apply the power of 2: 16384px X 8192px (your tile will then slightly override the next, and make sure this is smooth enough). In the right bottom corner, change the CRS to EPSG:4326 (WGS84) For higher resolutions you would use 512 or 1024 or 2048, for lower resolutions you would use 64 or 128. The -size256 gives a certain resolution in Atlas, meaning that each map generated will be 256x256 pixels. We will choose Google since I found tiles are less "cloud impacted". set FGSCENERYC:Program FilesFlightGearDataScenery C:Program FilesFlightGearScenery.
