Hi,

For what I can see France Digital Terrain Model resolution is good enough to be viewed at 1:100.000 scale and be close to 1 sample per pixel on the other hand Spain DTM roughly is 20 times less dense, there is an official source (Instituto Geografico Nacional / National Geographic Institute) available at 200, 25 and 5 meters per pixel for the whole Spanish territory.

Is there any chance you could use that source (it is free for personal use but I believe it is paid for commercial use) to improve the actual SD?

Hi Sky Panter,

Some days ago I was pretty close to go "smarty pants" and say something on the lines of " oh well, they want everyone with SkyDemon in a SRTM3 elevation model" luckily I didn't open my mouth that fast as apparently there are RA specifically designed for UAVs and ULMs http://www.wavenetradio.com/pdf/Cat-RA-01-GA-en.pdf

I have seen this thing at about 1600 Euro which I would say it is a reasonable price.

Hi Issac

Well, whadya know! I won't be so quick to open my mouth next time 

Actually, it looks like a nice bit of kit.
