3The Digital Earth/ 1
The vision of Digital Earth (DE) was proposed by Al Gore in 1998 as a multi-dimensional and multi-resolution model of the planet to contextualize the huge amount of geo-referenced information relating to the physic and social-economic environment.
Every day we create 1018 bytes of data and the 80% are geo-referenced or geo-referenceable data. It is an amazing amount of data that corresponds every day to a stack of DVDs covering the earth-moon distance. Fixed and mobile in-situ sensors (on satellite, aircraft, UAVs, ...), digital documents, social media contribute to create the Big Data in real time, we need to extract the useful piece of information from in real time to meet today's challenges. The issue was the acquisition of the data in the past. Now it is the smart management to extract useful information. Gore, A., 1998 The Digital Earth: underdstanding our planet in the 21st century,

• The Digital Earth is a set of distributed, multi-thematic, multi-resolution and multi-perspective archives of geo-referenced knowledge that allows to navigate not only through space but also through time,
thanks to the access to historical data as well as to the future predictions based on the environmental and/or social-economic models;
responds to the needs of different stakeholders: Scientists, Decision Makers, Communities, Citizens, Children ...
• The Digital Earth is based on the open access and participation (Geoweb2.0, Science2.0, ...) through multi-platforms.
• According to this paradigm, it will be possible - through both current devices (computer, tablet, smartphone) and new devices (not invented yet) – to access data, information, services, models, scenarios and forecasts: from simple applications to complex analysis related to the environmental and socio-economic issues.

5The Internet of Places
Objects (or things) will be connected and communicate through the network (we expect to have 26 billion devices connected within 2020) and, according to their location and time, they will react in different ways. The space-time field will model the Internet of Places, together with the Internet of People, the Internet of Information and the Internet of Things.

6The Internet of Everything
… The Internet of Things is becoming the Internet of Everything. Although much of the hype has been around things becoming part of
the Internet, the additive power of the Internet comes into play when things, people, places and systems work together. …
This describes a concept Gartner calls the "Internet of Everything." The Internet of Things is just one piece of this concept — alongside
the Internet of People (such as social networks or IM presence), the Internet of Places (such as Foursquare or any location that can broadcast information about itself), and the Internet of Information (for example, the World Wide Web, or systems that can share information through APIs or Web services)..

✔ Evolution of the 1990s GeoWeb 1.0✔ Interactive tools allowing user participation in spatial data management✔ OGC standards for geospatial interoperability✔ GPS, AJAX and mapping Application Programming Interfaces (APIs) ✔ Neogeography (Turner 2006)
GeoWeb 2.0
➔ creation of maps through mash-ups of multiple data sources
➔ the act of a mass of users to share a job through an open call
➔ the idea of humans acting as sensors able to acquire spatial contents
➔ users can easily perform real-time collection of georeferenced data✔ Diffusion of mobile devices equipped with sensors (GPS, camera, etc.)
✔ Volunteered Geographic Information (VGI) (Goodchild 2007)
✔ Crowdsourcing (Howe 2006)

✔ Set of practices in which citizens participate in data collection, analysis and dissemination of a scientific project (Cohn 2008)
✔ Active or passive
✔ Explicit or implicit
✔ Classification (Haklay 2013)
Citizen science – Our experience
➔ 'classic' citizen science: amateurs engaged in traditional scientific activities
➔ community science: measurements and analysis carried out by amateurs in order to set action plans to deal with environmental problems
➔ citizen cyberscience: use of computers, GPS receivers and mobile phones
✗ volunteered computing: citizens download data, run analyses on their own
computers and send back data to the server
✗ volunteered thinking: citizens perform classification works
✗ participatory sensing: applications centered on mobile phones capabilities
