arma3:terrain:satellite-image-resolution-size-explained [2017-01-30 02:41] snakeman created satellite-image-resolution-size-explained initial page. |
arma3:terrain:satellite-image-resolution-size-explained [2017-01-30 03:07] snakeman small tweaks, added grid cell link and arma 3 keyword heh. |

| - | It is up to you to decide what ratio to use, what quality do you want. One fact that does not depend on personal opinion about quality is large terrain size, for example 1 meter / pixel ratio with 40960 resolution image means you can do //only// 40km sized terrain. Now some might already run away scared when we talk about 40960 resolution images and many think even 20km is too large terrain. But that has nothing to do with the fact that the larger your terrain, the closer you are to photoshop editing limits like the mentioned 40960 resolution. | + | It is up to you to decide what ratio to use, what quality do you want.

| When we (PMC + some guys in arma2 community) did experiment with 40960 satellite texture resolutions, it was borderline doable with photoshop (no idea about gimp, if someone has info please let us know), but even then saving took several minutes while photoshop swapped to the disk like a crazy. This was with 16gb ram on win 7 64bit. | When we (PMC + some guys in arma2 community) did experiment with 40960 satellite texture resolutions, it was borderline doable with photoshop (no idea about gimp, if someone has info please let us know), but even then saving took several minutes while photoshop swapped to the disk like a crazy.

| Now with terrain builder we can [[arma3:terrain:import-satellite-in-smaller-tiles|import satellite texture / mask as tiles]] which eases the load while compiling our WRP (back in arma2 visitor3 we had no such option). So one could think that using larger resolution satellite images (than mentioned 40960) is now possible... | Now with terrain builder we can [[arma3:terrain:import-satellite-in-smaller-tiles|import satellite texture / mask as tiles]] which eases the load while compiling our WRP (back in arma2 visitor3 we had no such option).
