| If you have a very large, huge, satellite texture like above 40960 x 40960 resolution, it basically needs to be exported as tiles. Not only tiles but **enough tiles** so the tile size remains small, do not exceed 20480 resolution! | If you have a very large, huge, satellite texture like above 40960 x 40960 resolution, it basically needs to be exported as tiles.

| - | We would recommend tile size more close to rough 10,000 to keep them nice and small. Yes the more tiles you have the more cumbersome they are to import into terrain builder, but once you have exported the tiles you can use imagemagick to merge / stitch them together for more import friendly sizes if that's what you want. | + | We would recommend tile size more close to rough 10,000 to keep them nice and small.

| If you try to export too large tiles, then global mapper writes the BMP files somehow incorrectly and they are not readable with photoshop (or imagemagick). For example we tried to export 35,500 resolution images and it failed. This might be different for PNG 24bit files, needs to be tested, however for now you should export as tiles. | If you try to export too large tiles, then global mapper writes the BMP files somehow incorrectly and they are not readable with photoshop (or imagemagick).
