Wow, super interesting !

Saw from the heli, the Landscape with the terrain formation looks really beautifull IMO. Very important the presence of the geographic data.

Also interesting the animals ( I dont know how its name is.. u know ) when you pass with the helicopter in the video, is interesting, seems that you put some life into the environment. Nice detail.

The helicopter blades could be something like this pic ? , anyway in the youtube we cant see exactly how is its movements, but I liked a lot the travel across the mountains, rivers, very well made, dude.

Some sort of a glimpse of the process involved with the usage of DEM data would be also purrrfectly interesting and muuuuch appreciated, if not a proprietary secret

Man after see all the video, fantastic job ! Congrats again ( I was writing´n watching )

I´m looking forward to see the game demo here, keep it up !
