Satellite map images with missing or unclear data
Some locations on free, publicly viewable satellite map services have missing, incomplete, or unclear map data. In some cases, these regions have been intentionally digitally obscured or blurred. Westchester County, New York, for example, has asked Google to blur potential terror targets (such as an amusement park, a beach, and parking lots) from its satellite imagery.
In some cases, censorship of certain sites has been removed. When Google Maps was launched, images of the White House and United States Capitol in Washington, D.C. were blurred out; current versions of Google Maps and Google Earth show these sites uncensored, but with out-of-date imagery.

During talks with the Indian government, Google issued a statement saying "Google has been talking and will continue to talk to the Indian government about any security concerns it may have regarding Google Earth." Google agreed to blur images on request of the Indian government.
The Australian government has decided that images of sensitive areas are not a risk, due to poor level of detail. It was reported that in the lead-up to the APEC forum in Sydney held in September 2007 certain key locations in images of the city's central business district, where APEC leaders were meeting, might have been intentionally reduced in resolution; however, Google has indicated that the change was unrelated to APEC, while the NSW police said that they knew nothing about the change in Google's images. It is known that images of Her Majesty's Australian Prisons are intentionally blurred out. Images of the prime minister's official residence, The Lodge have not been blurred. However, images of its roof have been and the entrance to The Lodge is blurred in Google Street View.

East / South Asia
As of February 2013, North Korea is fully covered in Google Maps including Satellite view. Certain cities have a higher level of detail than others. Previously, Google Maps blurred North Korea. There was a single marker for Pyongyang; other towns and locations were identified only when using the search box.
OpenStreetMap has substantial coverage of North Korea.
South Korean online map services Daum Maps and Naver Maps, as well as Bing maps, censor a substantial part of their satellite/aerial imagery. Every military used land (US and ROK) is altered to show woodland or mountains. Also the nuclear reactor sites and many airports and possibly other civilian infrastructure. The national mint is pixellated. Google Maps does not have these omissions for South Korea.
