As expected, Apple today introduced a revamped Maps app for iOS 6 that ditches Google Maps in favor of an in-house offering developed by Cupertino.

During a presentation at this week's Worldwide Developer Conference (WWDC), Apple touted a "flyover feature" in the new Maps app that will include 3D views - a feature that Google also just announced for its Maps app.

The updated iOS app will not be available until the fall, when Apple rolls out iOS 6 (presumably with its next-gen iPhone). But when it arrives, the Maps app will replace the Google Maps app that currently comes pre-installed on all iOS devices.

Apple promised "vector-based map elements" that provide for smooth graphics and text, as well as "incredibly fluid" panning, tilting, and zooming.

The update will also include turn-by-turn navigation guides with spoken directions, a feature that is already available on Android, but has previously only been available on iOS via limited, third-party mapping apps.

Apple also promised real-time traffic information, with alternate route suggestions. Last year, amidst the controversy surrounding Apple's iOS location-tracking, a statement from Cupertino admitted that it was collecting anonymous location information to create a "crowd-sourced traffic database" that will be part of a future "improved traffic service."

Later that year, Apple acquired C3 Technologies, its third acquisition of a mapping company since 2009, so clearly, this revamped Maps app has been in the works for quite some time.

Meanwhile, Apple said its local search will incorporate information for over 100 million businesses with info cards that offer Yelp ratings, reviews, available deals, and photos.

Reports about an Apple 3D mapping solution first emerged in early May, when 9to5Mac reported that the next version of Apple's mobile OS would include "a completely in-house maps application." Later that month, BGR released a handful of grainy photos obtained from a "trusted source," which purportedly show the new iOS 6 Maps app.

Google beat Apple to the punch with a revamped mapping solution, however. Last week, the search giant demonstrated its own 3D maps technology, disclosing that a fleet of planes will fly above U.S. cities to provide map imagery in three dimensions. It also said that Google Maps for mobile will soon be available in offline mode.
