Darken Merge Picturemap Satellite Texture Tiles
HOWTO darken, merge and create picturemap from global mapper exported satellite texture tiles with Imagemagick.
In these examples we use global mapper exported 4 x 4 satellite texture tiles which is great number as it works on all satellite types from 20,480 all the way up to monster 102,400 resolution.

Darken
First batch file is to darken the satellite texture tiles. The command is -brightness-contrast -<VALUE> where you can use value depending on your satellite texture type, for example some dark green european forests don't need much darkening while bright desert of Iraq require huge amount of it. In our example we use value of -30 which seems to work more or less OK (depending on your satellite image).
Note that we convert global mapper exported 24bit PNG files here.
_run_imagemagick_global_mapper_darken_tiles_4x4.bat:
@echo off set MAGICK_TEMPORARY_PATH=c:\temp echo Dsat_A1 ... magick convert sat_A1.png -brightness-contrast -30 Dsat_A1.bmp echo Dsat_A2 ... magick convert sat_A2.png -brightness-contrast -30 Dsat_A2.bmp echo Dsat_A3 ... magick convert sat_A3.png -brightness-contrast -30 Dsat_A3.bmp echo Dsat_A4 ... magick convert sat_A4.png -brightness-contrast -30 Dsat_A4.bmp echo Dsat_B1 ... magick convert sat_B1.png -brightness-contrast -30 Dsat_B1.bmp echo Dsat_B2 ... magick convert sat_B2.png -brightness-contrast -30 Dsat_B2.bmp echo Dsat_B3 ... magick convert sat_B3.png -brightness-contrast -30 Dsat_B3.bmp echo Dsat_B4 ... magick convert sat_B4.png -brightness-contrast -30 Dsat_B4.bmp echo Dsat_C1 ... magick convert sat_C1.png -brightness-contrast -30 Dsat_C1.bmp echo Dsat_C2 ... magick convert sat_C2.png -brightness-contrast -30 Dsat_C2.bmp echo Dsat_C3 ... magick convert sat_C3.png -brightness-contrast -30 Dsat_C3.bmp echo Dsat_C4 ... magick convert sat_C4.png -brightness-contrast -30 Dsat_C4.bmp echo Dsat_D1 ... magick convert sat_D1.png -brightness-contrast -30 Dsat_D1.bmp echo Dsat_D2 ... magick convert sat_D2.png -brightness-contrast -30 Dsat_D2.bmp echo Dsat_D3 ... magick convert sat_D3.png -brightness-contrast -30 Dsat_D3.bmp echo Dsat_D4 ... magick convert sat_D4.png -brightness-contrast -30 Dsat_D4.bmp echo All done! pause exit
Global Mapper v18 exports indexed color palette BMP images, while imagemagick defaults to RGB so if you wonder why original bmp is 100mb and imagemagick processed is 300mb, well that's why. For more details refer to global-mapper export satellite bmp color palette.
picturemap_ca.tga
Second bat is to create arma3 user interface picturemap_ca.tga image which is shown when you load your terrain. This also creates “screenshot.png” which is 1024×1024 resolution image almost ready to go for web use.

Merge to 2 x 2 Tiles
Finally we merge the darkened satellite texture tiles into 2 x 2 tile setup; top left, top right, bottom left and bottom right.
You can also modify this bat file yourself to combine them into one monster huge satellite texture, however satellite sizes of 40960 or larger are very Very demanding to your computer (ours is win7 64bit with 16gb ram) so be warned before attempting to merge.
