Open Earth Monitor — Global Workshop 2023

From low-cost AirQuality stations to open standard (OGC SensorThings) and open data with open source solutions (FROST + QGIS plugin for sensors)
2023-10-05, 12:50–13:10, EURAC Auditorium

This is the story of 2 twin projects (namely AIR-BREAK and USAGE) undertaken by Deda Next on dynamic sensor-based data, from self-built air quality stations to the implementation of OGC standard compliant client solution.
In the first half of 2022, within AIR-BREAK project (, we involved 10 local high schools to self-build 40 low-cost stations (ca. 200€ each, with off-the-shelf sensors and electronic equipment) for measuring air quality (PM10, PM2.5, CO2) and climate (temperature, humidity).
After completing the assembling, the stations were provided to high schools, private households, private companies and local associations. Measurements are collected every 20 seconds and pushed to RMAP server (Rete Monitoraggio Ambientale Partecipativo = Partecipatory Environmental Monitoring Network -
Hourly average values are then ingested with Apache NiFi into the OGC’s SensorThings API (aka STA) compliant server of the Municipality of Ferrara ( based on the open source FROST solution by Fraunhofer Institute ( STA provides an open, geospatial-enabled and unified way to interconnect Internet of Things (IoT) devices, data and applications over the Web (
In second half of 2022, within USAGE project (, we released the v1 of a QGIS plugin for STA protocol.
The plugin enables QGIS to access dynamic data from heterogeneous domains and different sensor/IoT platforms, using the same standard data model and API. Among others, dynamic data collected by the Municipality of Ferrara will be CC-BY licensed and made accessible from municipal open data portal (

During the talk, a practical live demo will be showcased, accessing public SensorThings API endpoints exposing measurements (timeseries) about air quality (from EEA), water (BRGM), bicycle counters, traffic sensors (Municipality Ferrara).
The goal is to briefly explain the logic of the OGC SensorThings API standard (data model and API) and provide a practical experience of how to integrate standard-based dynamic data in GIS and webGIS solutions.

I am a GIS/SDI analyst since 1998.
Working at Dedagroup Public Services since 2005 (form Sinergis), in 2012-2013 I have joined the Joint Research Centre of European Commission, on INSPIRE-related projects.
I am passionate about maps, cartograms and storymaps, with focus on city-level data about air quality, energy performance of buildings, sustainable mobility.
From 2001 to 2010 I actively participated in ISO/TC211 and CEN/TC287 working groups on standards for geographic information and services.
In the last years I was involved in several innovation projects co-funded by Horizon Europe, H2020, EIT Climate-KIC, CEF Telecom and other programs.

Passionate about algorithm design and development, I have 15 years of experience in the field of data elaboration, analysis and visualization, in particular of data with a spatial / geographical component.
Over time I have worked in various fields, including climate modeling, intelligent transportation systems and earth observation, and I am currently developing data-related services for smart cities in the domains of energy efficiency of buildings, sustainable mobility and environmental management.
I am always looking for opportunities to apply my skills in challenging and innovative contexts, to work on solutions that have an impact on everyday life. I love international, multicultural work environments and cherish any opportunity to travel for work.
