Tech giant Google has purchased San Francisco-based startup Jetpac, creator of software that analyses the pictures cybernauts post on the internet and works up urban guides from the information it extracts.

Although the value of the deal remains undisclosed, the startup said on its website over the weekend that it would withdraw its Jetpac City Guides app from the App Store within days and work on projects with Google.

"We'll be removing Jetpac's apps from the App Store in the coming days, and ending support for them on 9/15," the company said on its website. "We look forward to working on exciting projects with our colleagues at Google."

Founded in 2011 with headquarters in San Francisco, Jetpac compiles information from the photos that users post on social networks — for example on Instagram, the property of Facebook — and by means of a system of artificial intelligence, creates guides with the information it extracts from them.

Google's purchase of Jetpac follows a string of recent startup acquisitions by the tech giant, including smartphone video creation platform Directr by YouTube earlier this month, and digital assistant messaging application, Emu.

The company also snapped up a handful of tech security startups earlier this year, in January buying Israeli smart identification technology startup SlickLogin, along with fraud and spam security startup Imperium .
