Carlo Masetto

I am an environmental engineer, with solid experience in environmental and territorial issues. I attended a post-graduate specialization course in GIScience and remote sensing for the territory management. Currently, I work as a GIS & remote sensing specialist at the Veneto Region - Territorial Planning Department - Cartographic Office.
Previously, I worked in the Municipality of Padua (Italy), as sustainable mobility & roads management and as technical employee in the HSE (Health, Safety, Environment) & Fire Prevention sector.
In my approach to work, it comes natural to me to deepen the aspects concerning the interactions between human sphere and environment.
Through my work in the Veneto Region, I have gained experience in the fields of cartography, remote sensing and earth observation data, particularly in the area of land monitoring and urban planning. I am also directly involved in the management of the spatial data infrastructure, where recently a section dedicated to remote sensing and earth observation has been made available.
I am the contact person for Veneto Region at NEREUS (Network of European Regions Using Space Technologies), where I was recently named as chair of Working Group in Earth Observation.
I am also the contact person for Veneto Region at National Council for Territorial and Environmental Information. (in Italian: CNITA). I have frequent contacts with colleagues of other regional functions and external specialists who work in the field of geographical information and who use products derived from remote sensing in the execution of their activities.


Evolution of the surface waters of the Po river in the 2020-22 period - a quantitative analysis of the drought effects with Sentinel-2 images

For Veneto Region, the year 2022 was affected by anomalies in terms of average temperature and recorded rainfall, compared to the climatic average of the last thirty years. The occurrence of these climatic conditions highlighted the inevitable negative effects for the environment; in particular, water resources were affected by this combination of climatic criticalities, both in terms of rivers’ flow rate and underground water flows, also due to the poor snow accumulations recorded in the Alps during the winter period.
Critical profiles in terms of surface runoff have been highlighted on various rivers and streams, particularly in the summer period. The main Italian river, the Po, was also affected by a water flow decrease in 2022, making evident the increase in the surfaces characterized by the presence of sand islands, visible along the river path.
This work, carried out by the Territorial Planning Department of the Veneto Region, aimed at a quantitative analysis of the surface covered by sand islands and surface water in a sufficiently representative area of the Po basin.
For the purposes of this study, the area included between the municipalities of Occhiobello (RO) and Ferrara was analysed (border area between Veneto and Emilia Romagna regions, where Po river flows). The analysis was carried out for the month of July 2022, comparing the data obtained with those relating to previous years (2020 and 2021).
In order to identify the islands of sand, multispectral Sentinel-2 satellite images were analysed, taking into consideration the wavelengths of the visible (B02, B03 and B04 bands), and that of the near infrared (B08 band). The area was then classified using supervised classification with the Random Forest classification algorithm, a methodology that allows to obtain high-precision classifications.
Considering the pixels’ size and the limits of the supervised classification, the precision of the analysis performed an accuracy higher than 95%. The analysis remarks relevance for monitoring the negative effects caused by the drought on the Po river. In the area under examination, a constant decrease in the surface of surface water was observed, and a corresponding increase of natural sand islands. From the analysis obtained, thanks to the use of the classifier, it is evident that the year 2022 was a year in which drought contributed to worsen the water stress for the Po river, with evident consequences on the environment in terms of availability of the water resource and the rise of the salt wedge near the river mouth. Moreover, the study presented here confirms the importance of using satellite data and classification tools for monitoring water bodies.

“Governance of Earth Observation Data - synergies at European level. The joint experiences of Nereus and the Veneto Region”

NEREUS (Network of European Regions Using Space Technologies) is a European association representing the interests of European regions that use space technologies whilst simultaneously highlighting the regional dimension of European space policy and programmes. It is the key mission of NEREUS, as a unique thematic network for matters of regional Space Uses, to explore the benefits of space technologies for European Regions and their citizens as well as to promote the use of space and its applications.
Veneto Region is a NEREUS active member since 2008, having played an active role in promoting space technologies (GNSS and earth-observation) during the years.
As one of the historical members of NEREUS, Veneto Region suggested some actions to boost activities on Earth Observation. Following the inspiring principle “Bringing the benefits of space uses to European regions and their citizens”, the proposal was to launch in 2023 the Working Group on Earth observation, composed by of regional experts and space technologies. The main ojectives are: 1) spreading the knowledge of earth observation data and space technologies; 2) sharing experiences that can lead to the creation of mutual synergies for a better data-governance; 3) supporting local institutions, citizens and companies in the use of space technologies; 4) inspiring and easing positive policy responses to local institutions.
In this framework, Veneto Region recently finalized the application for the Interreg Europe project “SAT.SDI.F.A.CT.ION (SATellite data and Spatial Data InFrAstruCTures for an evidence-based regIONal governance). In the same project, NEREUS is the Advisory partner.
European Earth Observation System Copernicus contributes as a vital source of knowledge to improve territorial and environmental management, efficient use of natural resources and delivery of effective public policies and services to citizens. However, it is still not clear to which extent satellite data are used by local and regional administrations, specifically how much satellite data are integrated within regional Spatial Data Infrastructure (SDI). Spatial Data Infrastructures, as defined by the INSPIRE directive, are to be considered as a framework of policies, institutional arrangements, technologies, data, and people that enable the sharing and effective usage of geographic information by standardizing formats and protocols for access and interoperability. The overall scope of the project is to promote the exchange and transfer of experiences related to the use of Satellite Data in local and regional Spatial Data Infrastructures (SDI), leading to a better, evidence-based governance of the regional territory.
The integration of Satellite Data in local and regional SDIs (Spatial Data Infrastructures) is of strategic importance and with great potential to support government and decision making at sub-national level, providing unrivalled information in different fields of application. However, the uptake of existing satellite data and services is not being fully used, and their integration in added-value services for regional and local governments is far from optimal. The SATSDIFACTION project aims at working exactly around this issue, promoting the exchange and transfer of experiences related to the use of Satellite Data in local and regional Spatial Data Infrastructures as a mean to improve the performance of regional policy instruments, eventually leading to a better, evidence-based governance of the regional territory.
