Spy plane Internet giant and Apple have caused concern in the U.S.

U.S. authorities have expressed concern about the "spy" aircraft, which Google and Apple used to create 3D-maps. Democratic Senator Charles Schumer wrote a letter to both companies, which declared that their "highly sensitive equipment for aerial photography" may violate the right of Americans to privacy.

In particular, Schumer fears that the optical technology of Google and Apple "may not be strong enough to see through the window, or even capture sunbathing in the backyard." The senator also expressed concern that the detailed 3D-models of cities may lead to a threat to national security. It is possible that three-dimensional maps can be used by terrorists to draw up detailed schemes of water supply and electricity in the U.S., he said.

In this regard, Schumer has asked both companies to notify residents about the time of shooting, automatically blur faces and retouch the strategically important infrastructure. In addition, each owner shall be entitled to "cover up" the image of his house on the map, writes TechCrunch.

At Google, on this occasion said that none of the measures referred to Schumer, the measures have not yet applied, but the company was willing to discuss this issue with the senator. Reaction of Apple is not reported.

Google announced the project to create a 3D-card on June 7. The first three-dimensional maps of several cities in the U.S. (which is not known) will be released in the IV quarter and year end the company expects to obtain detailed images of settlements with a population of 300 million people. Less than a week, voiced similar plans Apple.
