+Terra Incognita crashes if you try to use two of them at the same time, it happens when they move the cache directory. So unlike global mapper, you cannot run two instances of terra incognita at the same time.
+**Deleting Cache Files**
+This is recommended to do from windows explorer while terra incognita is not running, but you can also do this from map source -> clear cache.
+We don't have conclusive testing results if its a must to delete cache files regularly, but if you do not delete cache then terra incognita will move 10,000 files when such number is reached and you are about to start new download, this can cause huge slowdowns.
+If anyone wants to share their experiences with cache files please do.
+**OziExplorer as TIF**
+File -> Settings -> OziExplorer map (save): saving images as TIF makes it much quicker downloads, apparently as it does not spend time compressing the JPG its that much faster. But in the end part it slowed down, no idea why. **TIF IMAGES ARE HUGE, USE JPG INSTEAD.**
 **JPEG Quality**

 When you save large satellite texture in oziexplorer format, Terra Incognita automatically splits it up to smaller .MAP tile files. You can open these .map files with [[arma3:terrain:qgis-real-world-data|QGIS]] or [[arma3:terrain:real-world-data-global-mapper|Global Mapper]].
-There are many image sources to choose from but google maps seems to be the best.
+There are many image sources to choose from but ArcGIS World Imagery is clearly the best.
-Use 1m / pixel or 100m zoom level to achieve good results for arma3 satellite texture scale.
+Use maps.google 100m zoom level (1m / pixel) or ArcGIS 17 (1m / pixel) zoom level to achieve good results for arma3 satellite texture scale. Note: ArcGIS zoom levels are actually 0.8m/px for 17 and 1.6m/px for 16, but when exporting satellite with global mapper you can choose the exact resolution for terrain builder use.
-Unlike some other software *cough* universal maps downloader *cough* you wont get any problems with google banning your IP for 24hrs because you download too much. We have been downloading huge 75,000 resolution satellite images for days in row and no problems.

 QGIS layer -> add layers -> add raster layer, choose pcraster .map and select your terra incognita saved oziexplorer .map file. appears in QGIS main view OK.
+**ArcGIS** is world imagery and very good quality satellite texture source.
+ArcGIS zoom level 16 is 1.689036m/px and level 17 is 0.8445178m/px, unfortunately there is no nice round number of 1 or 2 meter per pixel scales in ArcGIS.
