If you care to know what those trees are that you pass on the way to work, there’s an app for that.

A new software application allows you to search and identify trees in San Francisco from where you’re standing, using information provided by the San Francisco Department of Public Works.

Just type in an address, the cross streets or even a ZIP code and mapping software will pop up with images of the trees on your block.

The application, which costs 99 cents “contains details of the nearly 65,000 trees from the Golden Gate Bridge down to Daly City that they keep track of and/or maintain,” according to an advertisement for the application.

The use of city data to provide information for residents is the goal of DataSF, which was recently launched by Mayor Gavin Newsom.
