 ====How Aerofly renders aerial images==== ====How Aerofly renders aerial images====
-Aerofly FS 2 uses textures ​with a varying coverage to render the earth. For this Aerofly FS 2 uses a level technique with different resolutions per level to render aerial images. At the base there is level 0. Level 0 consists of a single square image that covers the whole earth. This image would be used if viewing earth from very far away. Next is level 1. Level 1 consists of 2x2 images covering the whole earth. Then for level 2 we have 4x4 textures and so on. Aerofly FS 2 currently supports the maximum level of 15 which gives you roughly a resolution of 50cm per pixel.+Aerofly FS 2 uses images ​with a varying coverage to render the earth.

 Its recommended that your aerial images are converted to level 9, 11, 12, 13 and 14 to give a good coverage. Level 14 corresponds to roughly 1 meter per pixel. Please do not go below level 9 unless you convert a really large area with your images as Aerofly already includes those levels. Its recommended that your aerial images are converted to level 9, 11, 12, 13 and 14 to give a good coverage.
