If everything in MSFS is off by the same amount, then it may be a problem with Microsoft's spheroid code (or lack thereof). I know that Norm did a lot of work to get the WGS84 stuff right in FlightGear, and I'm amazed by how often roads and rivers *do* end up at the bottoms of valleys and canyons, given the different resolutions of the data. If everything in MSFS is off by different amounts (i.e. sometimes a road is in the right place, sometimes it's 200m to the north, etc.) then we're probably dealing with a resolution problem in the data. I think that vmap0 is nominally World Aeronautical Chart (WAC) resolution, 1:1,000,000; things will be off by a couple of hundred meters sometimes.
