•    What is overtourism exactly ?
•    How do you define “tourist flows” and “tourist crowds” ?
•    What exactly is the impact of overtourism on cultural and natural heritage so far ?
•    Managing tourism flows : who tried it and which great results have been obtained ?
•    What is the role of technology in the analysis and management of overcrowded tourist cities ?

The Herit-Data benchmarking study, managed by TURISME COMUNITAT VALENCIANA, analyses the management undertaken by diverse tourist destination, such as Amsterdam, Valencia or Florence, in relation to mass tourism, its  planning  and  lines  of  action ; especially when new technologies are used to manage the flows of tourists.

> Indicators Systems

HERIT-DATA is about using data to generate knowledge in order to prevent the negative effects of mass tourism on heritage sites. But how does this happen in practice? The first step is to know which data we want to collect.

On this purpose, our partners Turisme Comunitat Valenciana  and  Fundación Santa María la Real have developed a list of indicators to evaluate the evolution and impact of mass tourism in heritage sites (such as historic old towns, archaeological sites, or other areas with a cultural, historic or natural value).

The development of the indicators system has followed two main steps:

1.       The partners divided the indicators system into five areas of study: 1) Building / Site carrying capacity, 2) Flows of tourists in the city, 3) Perception of overcrowding by people, 4) Quality of the access to services, and 5) Quality of life of the residents.
2.       For each area, simple indicators were defined, such as the flow or number of visitors passing through a given place in a given period of time. Each indicator has a weight and importance within the area, which is also composed of other variables collected from statistical sources, surveys, monitored or historical data.

These indicators will be used to collect data on the six HERIT-DATA pilot sites in Florence, Valencia, Dubrovnik, Mostar, Pont du Gard and Western Greece. Each of these sites has its own characteristics: that’s why it will be possible to adapt the indicators to each context.

The indicators system, based on big data and open source, will allow to provide DMOs and Tourism Boards with a quick and precise knowledge about visitors’ behaviour and how the flow of tourists affects the state of conservation of a specific site.

> herit-data platform

The DISIT (Distributed Systems and Internet Technologies) Lab of the University of Florence has joined the project consortium to support the development of the HERIT-DATA platform by using an existing one they have developed: Snap4City.

The DISIT Lab will provide the Snap4City platform and technical support in order to collect the data from the six pilot sites in Florence, Pont du Gard, Mostar, Dubrovnik, Valencia and Ancient Olympia.

Tools for data analytics will also be provided, including predictions, social media data collection and sentiment analysis to support the study of the key indicators concerning tourism management.

Snap4City is a 100 % open source platform that provides a flexible solution to quickly setup a large range of smart city applications exploiting heterogeneous data and enabling services for stakeholders through IOT/IOE (internet of things/internet of everything), data analytics and big data technologies.

Snap4City is currently used by city officers, developers, companies and researchers, but also directly by citizens, in several cities, such as Firenze, Helsinki, Antwerp, Santiago de Compostela, Cagliari, etc.

The platform is used to improve city services, security and safety, but also to monitor a large number of indicators in real time.



To facilitate the transfer of the knowledge acquired throughout the project, the Herit-Data partners, draft a Mass Tourism Management model for the Mediterranean cultural heritage,  based on new technologies. It will gather all the developed definitions, experiences and methodologies towards the use of data and indicators, define a strategy towards the carrying capacity of destinations.

Once the mainstream model developed, it will be completed by a range of success stories, to showcase, transfer and mainstream the results of the Herit-Data project in other regional, national or supra-regional strategies, plans and policies..

•    Which parameters are affecting the impact of mass tourism and visitor behavior ?

•    What are the Best Practices on strategies to increase positive impact and avoidance or reducing the negative effects of tourism with the use of innovative technologies ?

•    Mass tourism management via new technologies ! What exactly does that mean and what do we need to integrate in our strategies ?

•    Which learnings help us to capitalize on Herit-Data experimentation ?

[Work still in progress]



A memorandum of understanding is a document, or agreement,  that indicates an intended common line of action between all the parties involved. The Herit-Data MoU will be about the use of  tools and methods to decrease the impact of mass tourism on cultural heritage sites, cities and monuments. The MoU will be signd by local, regional or supra-regional territorial authorities in Bruxelles.
