+ - Google Earth black out areas? 1

Submitted by Anonymous Coward
An anonymous reader writes "I was having a random look over different areas of desert using Google Earth after hearing about the patterns in the Chinese desert. For some reason I ended up in the Mongolian desert near Darkhan. Can anyone explain why, on near full zoom, there is a "blackout" area at these co-ordinates: 46.652052,109.496596 ? Not only here but if you zoom out a little, you can see a number of these black dots and getting a closer look they are sections which have been blacked out. I would, initially, have put these down as small lakes but the one I've given co-ordinates for isn't just a "blob", there definitely appears to be something to it's shape. If you move to the North East of this area, you'll also note a section which appears to have no updated aerial photography for a considerable amount of time in comparison to the area around.
Can anyone shed light on this stuff for me?"

Google Earth black out areas?

  • The mapping algorithm for the satellite photos tries to predict water, and at this spot in the desert it got it wrong. Try comparing these blacked out spots to a lake someplace else.
