Exploring Poland on Google Maps shows an interesting pattern.

Many areas in Poland have hi-res satellite images however when you get close to a death camp like Auschwitz, Birkenau, Treblinka, Sobibór and others you for some reason see only low-res imagery, which will not let you see any details of the death camps.

In some cases you can clearly see the difference in the image resolution as you get close to the camps.

Google is known to blue sensitive buildings like military facilities or government buildings, but to blur the Holocaust death camps it seems inappropriate.
