Apple has launched the 'Maps Surveyor' app for iPhone, designed to help improve its Maps app by collecting data.
The app is not publicly available and seems to be for use by companies that partner with Apple for mapping tasks.
Users are directed to another app called Premise where mapping tasks are assigned and users can earn rewards by completing them.
The Surveyor app instructs users to attach their iPhone to a mount, rotate it to landscape orientation, and capture images along a route while driving.
