False positives - where to report? #31

Hi, Very cool project. In many cases this works and are a cool resource. But unfortunately around where I live in Sweden there are to many examples of buildings detected that are in the ocean, on cliffs/bare rocks, just shadows in the forrest etc.

Is there a plan to rebuild this data set so you are interested in getting feedback on what has worked or does not work?

I added four examples below that are all within 5 km distansce from each other. Non of the marked buildings as seen in the images are actual buildings. The satelite imagery shown as background are bing satelite imagery. http://ecn.t3.tiles.virtualearth.net/tiles/a{q}.jpeg?g=1, which is stated to be bing virtual earth. I am not entirely sure if that is the imagery used but anyhow - in real life there are no buildings in the places where this project has indicated there is one.
