Google's New 'Plus Codes' Are An Open Source, Global Alternative To Street Addresses (9to5google.com) 183

Posted by BeauHD on Wednesday March 14, 2018 @06:00AM from the global-code dept. Google has developed a "simple and consistent addressing system that works across India and globally." Called "Plus Codes," the location-based digital addressing system is designed for people with addresses that are not easily located through conventional descriptors like street names or house numbers. That's half of the world's urban population, according to a World Bank estimate. 9to5Google reports: Notably, this open source solution composed of 10 characters works globally and can be incorporated by other products and platforms for free, with a developer page available here. It works offline and on print when overlaid as a grid on existing maps. Places that are close together share similar plus codes, while the system is identifiable by the "+" symbol in every address. "This system is based on dividing the geographical surface of the Earth into tiny 'tiled areas,' attributing a unique code to each of them," reports Google. "This code simply comprises a '6-character + City' format that can be generated, shared and searched by anyone -- all that's needed is Google Maps on a smartphone."

The first four characters are the area code, describing a region of roughly 100 x 100 kilometers. The last six characters are the local code, describing the neighborhood and the building, an area of roughly 14 x 14 meters -- about the size of one half of a basketball court. The area code is not needed when navigating within a town, while another optional character can be appended to provide additional accuracy down to a 3 x 3 meter region. Users of Google Maps in India will be able to easily find the plus code for any area in the app, while the mapping service along with Search will support the entry of the new coordinate system. Plus codes for any location can also be found with this tool.
