Last week Apple launched Maps Surveyor, a mapping app with a specific purpose, MacRumors reports. “The app is not public facing and appears to be for use with companies that Apple partners with to assign mapping tasks. […] Strings in Apple’s Surveyor app found by MacRumors suggest that once assigned a mapping task by the Premise app, Premise users will be instructed to attach an iPhone to a mount, rotate the iPhone‌ to landscape orientation, and capture images along a route while driving using the Surveyor app.” In other words, it’s the user end of a crowdsourcing pipeline that funnels local data to Apple Maps via a third party “task marketplace.” Not something most of us would ever use.
