One of the rumored features in iOS 6 is a new maps service, as Apple aims to offer an in-house rival to the currently-used Google Maps. Google is rumored to be offering an updated version of the service ahead of WWDC on June 11.

Brian McClendon, Google vice president for Maps, didn't answer questions on an imminent update. "We will continue to make Google Maps available as widely as possible," he said.

The relationships between the two companies has degenerated since Google introduced its Android operating system in 2008. Android has experienced faster growth in its app store, though the quality of apps has been questioned, while the mobile OS is the most popular in the worldwide partly due to the range of devices.

"Processing the mobile mapping request from users of Apple's devices has provided Google with valuable insights into people's whereabouts and preferences. That, in turn, has helped Google sell more ads to local businesses," Philly.com reported.

According to the Web site's report, the updated features for Google Maps won't be available for weeks. It says the service will support downloading mobile devices and "more three-dimensions imagery."

Google revealed the service has 1 billion users. It has provided 26 million miles of driving directions, and 75 percent of the U.S. population can can see a high-resolution image of a home. Six years ago, that was 37 percent.

The Street View feature has been enabled across 5 million miles, which allows areas to be see on ground level.

"The company has raised privacy concerns by posting photographs that include people in unflattering situations and, at one point, including equipment that vacuumed up personal emails sent over wireless networks that weren't protected with a password," Philly.com added.

Obscure areas will also get photos, such as the Grand Canyon, and the photos will be taken from equipment designed to be attached to a backpack. The equipment will be used on photo-capable bikes, instead of cars.

Planes will also photographs cities to "conjure more realistic three-dimensional views of metropolitan landscapes in the Google Earth version of its maps." The photo taken by planes are automatically converted into 3D replicas.
