A Franklin Park couple has launched what may be the first legal challenge to Internet heavyweight Google for posting street view pictures of their home on its Web site.

Google Maps' Street View mapping feature, which was launched in May, shows 360-degree camera shots of the exteriors of homes along a street. Google mounts a digital camera on top of a vehicle and drives around various neighborhoods recording footage, according to the suit.

Christine and Aaron C. Boring claim in a lawsuit filed Wednesday in Allegheny County Common Pleas Court that Google violated their privacy by filming or videotaping their home and swimming pool from Oakridge Lane, a private road, without permission.

A Google spokesman said the lawsuit had "no merit."

Ms. Boring, a schoolteacher, and Mr. Boring, a computer programmer, bought their four-room Franklin Park bungalow in October 2006 for $163,000, according to Allegheny County's real estate Web site. Built in 1916, the house is 984 square feet. The entire property is 1.82 acres, including a 50-foot right of way.

"A major portion of their purchase decision was a desire for privacy," the suit says.

They charged Google with "a substantial and highly offensive" intrusion, saying Oakridge Lane is marked with a "Private Road" sign and Google's photographers would have had to enter it to capture the images.

They are seeking unspecified damages in excess of $25,000 for invasion of privacy, trespassing, negligence and lowering their property value. The Borings also asked the court for an injunction to remove any and all pictures from the Web site and requested that it "cease and desist" from entering their lane or any other private roads.

Attorney Dennis M. Moskal, who represents the Borings, said he's been flooded with calls from reporters around the country about the case.

"We were surprised there was no other case like it. It was bound to happen, a company like Google going face to face on these privacy issues. There had to be somebody to get them to alter the course of the big giant," he said. "What happened to Google's responsibility? Their code of conduct starts with 'do no evil.'"

Larry Yu, spokesman for Google, said: "There is no merit to this action. It is unfortunate litigation was chosen to address the concern because we have visible tools, such as a YouTube video, to help people learn about imagery removal and an easy-to-use process to facilitate image removal.

"As a matter of policy, imagery for Street View is taken in public streets and what any person can readily capture or see in the public domain. Street View is a popular, engaging feature that allows people to easily find, discover, and plan activities relevant to a location."
