The document discusses the transition from Digital Earth to the Internet of Places and how geospatial data and technologies can be used for risk and emergency management. It provides examples of participatory mapping projects conducted by the GEO Laboratory, including reporting potholes, architectural barriers, and cultural points of interest. The laboratory is developing open source platforms like PoliCrowd to enable collaborative geospatial data collection and visualization.

3. 3 The 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.

The Digital Earth/ 2
• 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.

5. 5 The 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.

6. 6 The 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)..

GeoWeb 2.0
✔ 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)
➔ creation of maps through mash-ups of multiple data sources
✔ Volunteered Geographic Information (VGI) (Goodchild 2007)
➔ the idea of humans acting as sensors able to acquire spatial contents
✔ Crowdsourcing (Howe 2006)
➔ the act of a mass of users to share a job through an open call
✔ Diffusion of mobile devices equipped with sensors (GPS, camera, etc.)
➔ users can easily perform real-time collection of georeferenced data

Citizen science – Our experience
✔ 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)
➔ '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
