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D.C. were blurred out; current versions of Google Maps and Google Earth show these sites uncensored, but with out-of-date imagery.

Countries in official contact with Google Maps

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.

The government of Malaysia has stated that it will not ask Google to censor sensitive areas because that would identify the locations it deemed to be sensitive.

List of map locations with missing or unclear data

East / South Asia

South 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.

Taiwan

Rounded irregular areas overlaid with older imagery, etc.

Turkey

All satellite images of Turkey for certain zoom levels are either missing or blurry countrywide on Google Maps. This problem was first discovered in Google Maps for Android app. Then, it turns out the problem is not platform-specific and countrywide. The satellite images are also blurry in the maps.google.com.tr domain since September 2015, but not in the maps.google.com domain. Lots of people are reporting the same issue in Google product forums but the problem still continues and there is not any statement made by Google about the issue. There is no problem in satellite images with Bing Maps, Yandex Maps, Yahoo Maps and Apple's Maps.

Maps TimeLine is also not available on Google Maps for Mobile. Just as the satellite view problem, Location History can be seen on "google.com/maps" domain, but not on the mobile phone and "google.com.tr/maps" domain.
