Google Maps rolls out offline search and directions

MOUNTAIN VIEW, Calif., Nov. 10 (UPI) -- Google upgraded its Maps app for Android devices to include offline search and directions capabilities.

The Califonia-based search giant will allow users to navigate and find business locations, opening hours and phone numbers without a live Internet connection. An update to the iOS version is forthcoming, the company said.

Google sought to provide functionality for tourists visiting places outside of their mobile network's reach and for whom roaming charges would be prohibitively expensive.

Offline functionality has existed in a different from since 2012, when Google first allowed users to cache certain areas. However, saving an entire city will now return results for business and location searches without a cellular connection. User reviews and photos will not be downloaded, in an effort to save space.

Offline navigation will function by using average traffic time data as opposed to real-time info. Walking and transit directions will not yet be available offline.

However, the offline functionality may stress Android devices with low amounts of on-board storage. Ben Wood of CCS Insight told the BBC that some entry-level Android devices only have four gigabytes of internal storage, which can quickly be depleted with "a few applications, some music and perhaps a video."

Wood said this might impact Maps' offline functionality depending on the size of the information downloaded. Google provided some examples, including a 380-megabyte download to cover most of Greater London and an about 200-megabyte download for the San Francisco Bay area.
