 And process these through [[http://www.qgis.org/en/site/|QGIS]] (free open source program) into terrain builder and finally into finished arma3 terrain addon.
-**I do not know if all of the above is possible, terrain is but mask? vegetation? No idea yet, I'm learning one step at the time.**

 You should download [[arma3:terrain:satellite-texture-terra-incognita|Satellite Texture with Terra Incognita]] instead.
-====== QGIS Print Composer ======
-Print Composer will save an image of your current view.
-Open it by Project -> new print composer, or use CTRL-P
-Make it a square pare size, for example 100mm x 100mm.
-Select layout -> add map, drag a box around the white area.
-The view should look like your current QGIS main view, hide/show layers to get the view you want like google satellite.
-Item properties -> extents, no idea what to do with those :)
-FinCenturion: you need to know now exactly how large of a chunk you need. and the coordinates / extents of this data. I have changed up everything to match arma worldspace by using the methods in my [[arma3:terrain:qgis-reproject-transform-tutorial|QGIS Reproject & Transform Tutorial]].
-FinCenturion: but you need lower left corner x,y and upper right corner x,y coords\\
-FinCenturion: if you have more data than you will need you can of course use an area that is in power of two - so you can keep the horizontal scale 1:1 with real life\\
-FinCenturion: say you want to do a 4096 x 4096 m map, and your lower corner is in the (fictive) coords of x 1000 and y 1000 - > exents 1000, 1000 and 5096 and 5096\\
-FinCenturion: if that made any sense :smile:
-To save the image use composer -> export as image

 When reorder is OK then just click run button and it creates refactored layer with the new reordered fields.
-====== Misc Notes ======
-**QGIS**
-[4:09 PM] NigeyS: oo reproject and transform... yeah thats gonna give me a headache\\
-[4:19 PM] FinCenturion: for image export purposes you dont need to reproject and transform\\
-[4:19 PM] FinCenturion: but if you wish to use shapefiles straight up in TP or TB you do\\
-[4:20 PM] NigeyS: atm i just need to get it into photoshop for the layer mask\\
-[4:21 PM] FinCenturion: to use print composer make  a new print composer, then under the composition tab in the workspace make sure the page is square, i use 1000x1000mm\\
-[4:22 PM] FinCenturion: then use the add map function from the layout drop down box\\
-[4:22 PM] FinCenturion: scale the newly added map to cover the white sheet\\
-[4:22 PM] FinCenturion: then click on your new map, go to the item proprties tab on the right again\\
-[4:23 PM] FinCenturion: use the Extents to get the correct display\\
-[4:23 PM] FinCenturion: so you basically need to know pretty exact coords of your map\\
-[4:24 PM] FinCenturion: that is why sometimes it's better to have all your shape data reprojected to arma 3 TB worldspace\\
-[4:24 PM] FinCenturion: anyhoo, then you use the export image button and set a file name, then final resolution\\
-[4:25 PM] FinCenturion: it's a bit of a bother at first but QGIS is a massive help once you get used to it\\
-[4:26 PM] NigeyS: that'll help thanks, i have all the co-ords etc
-====== Open Questions ======
-Snake Man: ok when you choose area of terrain you want to download, do you just get "bulk" data with large amounts of room to maneuver or do you get square power of two exact size for arma3 use like 10km x 10km?
-Answer: for global mapper you just get bulk data and cut it there, no idea if this is possible in QGIS...
