MAK Earth presents: the Guam Terrain

MAK Earth now includes increased resolution for the Island of Guam and the surrounding waters (bathymetry) and islands. So if you're simulating operations in the Western Pacific Rim and need to stage assets on US territory, Guam ("Where America's Day Begins") could be an ideal location for your scenarios. Take a look at this virtual tour video of G...

A solid foundation to a bigger, better world

Whole-Earth simulation
I spent a few minutes pulling threads about whole Earth simulation out of Jim Kogler's mind. Here's what I learned: There seems to be a general misunderstanding these days about the ability of game engines and military simulation systems to accurately represent the whole planet Earth in training simulations. Jim, why are people interested in modeli...

Earth — Big and Round

Earth — Big and Round

When we create a virtual world for modeling, simulation & training, does it matter if we use a “round-earth” coordinate system and 64-bit precision in our coordinates? Yes, but much more so in some circumstances than others. 

Let’s start with the basic concepts. We all know that the world is round, well round-ish, but most of the time we can’t see the effect. When you stand on a rise and look into the distance it’s the shape of the topology that dominates your view. You can’t really see the curvature of the earth.
