Microsoft's product looks great, I'm interested to see how it performs, what subscription service it requires and how it serves up the scenery.
Let's take a look at something slightly more practical: Comparing the photo here viewtopic.php?f=5&t=36145#p354466 to a Google Satellite of the area.
What we really need to focus on is the small details. Often landing on runways has felt a bit weird in FG because the runways have been scaled to feel much bigger or smaller than in real life.
The cliffs in the Wollongong shot are a little too dramatic, but other than that, the representation's sensible. What we really need is for someone to take the next step into texture blending with land cover transitions and higher definition textures. If we can make something look good on the ground, it will still look good at altitude. It will be hard work, but I think it's definitely possible, but we need to be focused on draping things over the triangulated mesh as opposed to burning the triangulated mesh into the ground.
