So after trying a lot:
i made a terrain 2048 *2048 in editor and tried to import a
*.r16 file : the file is not present (hidden) in the dialog box explorer
*.raw file : file present in explorer dialog but result in failed to load in editor.
then with code (lua) no problem for each file: it loads  (though i think better result with r16 one)
don't know why in dialog explorer r16 is not seen
, so i put my file here (needed to rename extension because no allowed to upload *.r16 ), if you want to try (not a great elevation from 5m to 45m)
 
Total_G_HM.r16.txt

Ok i got it,
simply by positionning the sprite in 2D coords like -400,300
x negative on the left side, x positve on the right and y positive on top side and negative in the bottom
0,0 is the center of the window
