The Environmental Impact Hub (EIH) is a data infrastructure that is being developed within the framework of I-CHANGE to enable easy, user-friendly access to the project’s data and analysis output. Moreover it allows for a feedback loop of the citizens to the project, thus supporting citizen science and engagement.  

From an architectural point of view

The EIH integrates different components, namely the Data and Information Broker, the Citizen Observatory Archive, the Quality Assurance Platform, the Processing Platform, and the Dashboard.

The EIH is serving observational data from the Living Labs, that has been ingested, standardized and labelled with semantically meaningful metadata, quality assessed and stored in the Citizen Observatory Archive. From there, it is made available through the Data and Information Broker. This demonstrates full end-to-end capability, from observations being collected at the Living Labs, through to provision of access to, and dissemination to end users. 

This month (May 2024), the final release of such core components has been deployed and the EIH, as a participatory platform, currently collects observational datasets from heterogeneous sources as personal weather stations (e.g. Acronet), meteorological sensors that can be attached to motorised vehicles and bicycles (e.g. MeteoTrackers), air quality sensors (e.g. SmartCitizenKit) amongst others, as well as manually collected observations datasets. More data sources will be included by the end of the project.  

In terms of functionalities

The infrastructure serves for data collection, quality checking, sharing, pre-processing, as well as discovery and access capabilities to the I-CHANGE Living Labs. Further, it provides an access point for users to exploit I-CHANGE data and visualization services.

The latter is obtained through the I-CHANGE Dashboard providing user-friendly access to tailored processed data, applications and tools designed/provided within I-CHANGE Living Labs. In particular, the Dashboard is oriented to a non-technical public and provides an easy to use and rich interface to expose citizen-oriented analytics and visualization systems, services based on spatial data as well as interactive tools for visual storytelling. The Dashboard also connects to the apps developed and/or exploited during the project, e.g. the YETI app.

Both the Dashboard and the apps for behavioral change are currently under development.
