 BTW If you want to //test// this, you can import same satellite image more than once, when you do it second time it shows up in layer manager -> raster as "<filename> -1" name, second same image import appears as "<filename> -2" etc. Also you don't have to use large 20480 x 20480 image, you can take even 1024 res image and import that, you stretch it over the wanted area in terrain builder layer settings. BTW If you want to //test// this, you can import same satellite image more than once, when you do it second time it shows up in layer manager -> raster as "<filename> -1" name, second same image import appears as "<filename> -2" etc. Also you don't have to use large 20480 x 20480 image, you can take even 1024 res image and import that, you stretch it over the wanted area in terrain builder layer settings.
  
-This example uses 40960 x 40960 satellite resolution, but you can use it to smaller sizes too (or larger I guess? heh). We assume your satellite **tiles** are 20480 x 20480 resolution and there are 4 of them to be joined as one 40960 resolution final satellite image.+Take your terrain size and divide by two, this resulting number is what you use to type into terrain properties to align the satellite image tiles (do not confuse to "satellite tile size" heh).
  
-Basically your tile resolution will be added to the easting / northing coordinates. Easting by default is 200000 so you add 40960 to it which comes to 240960 value. Northing is bit easier as its zero, you simply add your tile size as-is there where necessary.+In our example we use 81920 sized terrain (81.9km) with 40960 x 40960 satellite resolution, but you can use this method to smaller satellite image sizes too (or larger I guess? heh). We assume your satellite **tiles** are 20480 x 20480 resolution and there are 4 of them to be joined as one 40960 resolution final satellite texture / mask image.

 +====== Simple Example Values ====== 
 + 
 +To make this simple, here are couple of other example values. 
 + 
 +Remember, terrain size divided by 2 is your satellite tile value (satellite texture sliced to four tiles). 
 + 
 +**Example 1**\\ 
 +Terrain size: 102400\\ 
 +Terrain properties size: 51200 (terrain size / 2) 
 + 
 +**Example 2**\\ 
 +Terrain size: 57344\\ 
 +Terrain properties size: 28672 (terrain size / 2) 
 + 
 +**Example 3**\\ 
 +Terrain size: 20480\\ 
 +Terrain properties size: 10240 (terrain size / 2) 
 + 
 + 
 +====== Tile Example Values ====== 
 + 
 +Satellite tiles for terrain builder import, how to import them with proper values. 
 + 
 +Formula is mapsize - tile size == northing slots. subtract tile size from previous slot to get down one row.
