[SOLVED]Heightmaps panic

Recommended Posts

Greeting everyone, I've just finished doing the Atlas guide and turns out creating a terrain isn't that complicated after all... that is except the very first step, getting the terrain heightmap.

 

In Atlas guide he provides one .asc as example however like most creators have done and as BIS suggest, I also wanted to use a custom terrain from a real life region in the world. This is where the problem starts, it's not like I haven't got the resources, but rather they don't seem to work as I'd expect.

 

Because I didn't get how to get a .arc file I tried using a standard .png Black and White image since TerrainBuilder appears to accept and is much easier to generate one, however when I imported into Terrain Builder's bulldozer, it showed up as all spiky and not as smooth as it appeared.

So I went to do some research in the forums and read about this software called "L3DT", I've somehow managed to import the heightmap into the program and it told me the scale of the height were completely out of proportion, which explained the giant spikes in bulldozer.

 

So I thought considering so many people talk about this SRTM format n' stuff I guessed my only chance was to do the hard way, so I went looking on my national archives for some kind of geographic files and managed to find one WMS layer that I was able to import into QGIS which BIS uses as example, it's not as sensitive as the B&W one but if there's no alternative I could live with that, the problem once again is that I have no idea how to export the region I want into .arc .

I've searched both the forums and the internet for GIS related information and I've quite lost my senses as to what I should actually do after all.

 

So I was hoping someone with more experience than me, could lead me in the right way.

Thanks for your attention :)

Thanks, I believe the problem was that i didn't ajust the greyscale min/max heights.

 

Just incase someone else passes by, this was the grayscale heightmap generator I used, but I guess the one he mentions in the videos is more reliable.
