Middle Earth DEM Project

oh yes, if you could jot down the pixel coords of the extents of subset of the terrain that you cut in Condor 3dem, I can use those to rectify any textures or terrain for that matter into the core data here, from your project.

I've uploaded the terrain. It's 7344 x 5041 at 100m (734 x 504 km). Gives you leeway to crop down to the max size.

I've removed the -999999 border along the south and east.

The link to the terrain as a 16 bit png so you can put some airstrips in:

ps, it's going to be easier for me to rectify and reinsert the georef info if you do the modelling on the terrain as is, without cropping it in 3dem. Once I export the final tile set, then crop it.

Is there a way we can extend those files down to the southern faces of the Ephel Duath?

I want to try a variety of crops in 3DEM, and I'd really like to include the full length of the western range, if possible.

And surprisingly it looks like there are plenty of flat areas for airstrips already, so uh, I don't think I need to do any editing *laugh*.

We could either set the rectangle to 720 high x 480 wide, rather than 720 wide. Presuming that would still be ok for your software, or accept the loss of realism and you work on the basis of half real world extents. Don't see why not, I work like that all the time in World Machine for visual effect. I'm guessing the limitation of 720 x 480 is one of pixel dimensions, right?
3dem will see the terrrain as covering the real extents, but once you output to Terragen format you'll lose the georef info anyway, the old TG is not georef aware.

What you prefer?

Been a long day...Condor will still see it as the full extents. So...what about trying the terrain at a reduced res? Say 3/4. As long as the pixel dimensions are within those limits, everthing should be ok, unless your software has some hard wired limit on ground r-w extents.
