I'm following the ZGM Arma 2 Map Making Tutorial (can be found on armaholic but I can't post links yet) in my first attempt at a terrain project for Arma 2.
I haven't gotten very far into the tutorial as it says to use 'Global Mapper' to convert my DEM file to xyz, but Global Mapper isn't free and I can't find a trial key for it, so instead I am using MicroDEM.
This has presented a big problem because I haven't been able to find any in depth guides for the program relating to Arma 2 and Visitor 3 compatibility - yes I HAVE searched the forums, and armaholic, and google... lol
SO, basically I have a DEM file, which I know how to open in MicroDEM, and I think I've worked out how to crop (or 'subset') the area of terrain that I want. (But I'm not sure about that :/)
My first question is how can I crop or subset part of my DEM at a specific size? I want to make a map 15km by 15km, I have the long & lat co-ords for the area I want to use from my DEM but not sure how to get an exact size - which I think is necessary for Visitor.
Next i obviously want to export it as an xyz file, so my second question is what settings I need in the export process to make the xyz suitable for Visitor.
Again I've played around with the software and have a vague idea of what to do, but don't know what settings I need to make it visitor compatible, I've tried a few different combos but no luck so far.
When I try to import the xyzs I create with MicroDEM the width and height are not what expected (don't know how to get exact measurements) and my 'square size' is 1.0 instead of 10. (so atm result size = 4096 sqm)
Any help or pointing me towards where I might find a solution would be greatly appreciated.
