The data will come from smart surveys, which combine the collection of data captured by the several sensors available in smart phones (e.g. accelerometer, location) with data entered by the users (e.g. activities performed).
Part of the data will be collected by the participants and volunteers they recruit. Eurostat will provide access to a framework for the collection of geo-coordinates and sensors data collected by smart devices. The framework will be composed of an App which will capture the data, a remote server (to where the data will be securely transmitted) and possibly some predicted variables (e.g. mode of transportation used).
A dataset of the same nature previously collected will also be provided.
