A fix for Terrain Builder coordinate and export/import issues.

Recommended Posts

With the April 2 release of Terrain Builder this is no longer an issue; it now comes with the required "proj.dll" library.

In summary, if you want to fix importing of shapefiles and many types of images (including certain TIFF images) you need to download this package:

http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1400-gdal-1-7-3-mapserver-5-6-5.zip

You then copy only proj.dll from the ZIP file and place it in your Terrain Builder folder, which is normally:

C:\Program Files (x86)\Steam\steamapps\common\Arma 3 Tools

(This is an official binary of the "GDAL" project, you can see it on the list on http://www.gisinternals.com/sdk/, which is linked from the GDAL homepage)

Hopefully BIS will include proj.dll in future versions of the Arma 3 Tools, but for now this works just fine.

The reason for this requirement is that Terrain Builder internally maintains all map objects in "real world" coordinates (which is why you have to select UTM zones) even if you aren't using them for your map.

In the process of doing this, it needs to be able to convert between various map grid systems. Even when no conversion is required (for example when re-importing something exported from your project) it uses a transform (albeit a one to one transform).
