SAN FRANCISCO -- Google (GOOG) and Apple (AAPL) are attracting renewed scrutiny in their practices as a result of privateness issues -- this time for flying "military-grade secret agent planes" over best U.S. towns as they race to shore up their rival 3-D mapping services.

Staffers for Sen. Charles Schumer, D-N.Y., met with Google officers on Monday to speak about privateness problems associated with the camera-equipped planes. They plan to fulfill

with Apple on Friday.

The senator's administrative center additionally plans to succeed in out to Microsoft and different firms that can be creating equivalent technologies.

In his letter, Schumer raised considerations over Apple's and Google's said "virtual mapping plans that use

military-grade undercover agent planes with sufficient precision to look thru windows, capture targeted photographs of personal outdoor activities, and document photographs as small as 4 inches."

Mountain View-based Google and Cupertino-based Apple every unveiled new 3-D mapping products and services this month at separate occasions. The maps allow customers navigate round an aerial view of a town that looks a lot more practical than flat, top-down satellite-based photographs at present to be had in mapping products.

The firms are racing to advance newfangled virtual maps, a key characteristic as they compete to draw customers to their rival telephone offerings.

However the recent attempt marks the company's most vital use of the planes in a scientific approach to construct an ordinary function in a single of its products.

Google has confronted scrutiny over mapping services and products within the past, corresponding to with the camera-equipped "SIDE ROAD View" vehicles that crisscross the globe taking panoramic footage of streets for its widespread mapping service.

In 2010, Google said that the so-called Boulevard View automobiles had inadvertently gathered emails, passwords and different non-public knowledge from house wi-fi networks. Accumulating the Wireless knowledge was unrelated to the Google Maps venture; it was performed in order that Google may just accumulate information on Wireless scorching spots that may be used to offer separate location-based services.
