From "Free Information" to Its (Geo)referencing and Analysis: The "Costs" of Open Source
Full text linkENG-Is it possible, starting from free data or free information, also available
online, to get a representation of them on paper, consequently highlight-
ing the real spatial component? How to handle normal address lists and to
achieve their transformation into geographic coordinates, expressed in lati-
tude and longitude? What difficulties come up against and how can we face
and overcome them? This contribution, trying to return an updated image
of the current situation, highlights potential and critical points of mecha-
nisms and procedures rarely accessible in an effective manner. Finally, it
dwells on the opportunities offered by information sharing and knowledge
since they facilitate the individual and collective growth, the participatory
processes and the social justice. ITA-È possibile, a partire da dati o informazioni libere, disponibili anche in rete, ottenere una loro rappresentazione grafica che ne metta in evidenza la reale dimensione spaziale? Come gestire semplici liste di indirizzi e ottenere la loro trasformazione in coordinate geografiche, espresse in latitudine e longitudine? Quali difficoltà si incontrano e come si possono affrontare e superare? Questo contributo, cercando di offrire un quadro aggiornato della situazione attuale, mette in evidenza le potenzialità e i punti critici di meccanismi e procedure volti a ottenere questi risultati. Infine, vengono sottolineate le opportunità offerte dalla condivisione di informazioni e conoscenze in quanto possono agevolare la crescita individuale e collettiva, i processi di partecipazione e la giustizia sociale

No full textThe increasing demand for renewable energy has led to a growing interest in ground-mounted photovoltaic (GMPV) installations. However, the selection of suitable locations for these installations requires a multi-dimensional evaluation that integrates regulatory, environmental, and technical constraints. This study addresses the challenge of locating suitable land for GMPV systems in Italy. We develop a spatial decision support model that integrates Multi-Criteria Analysis (MCA) with Geographic Information Systems (GIS) to incorporate multiple factors, including regulatory requirements, hydrogeological and geotechnical hazards, land use attributes, solar irradiation potential, proximity to infrastructures, and terrain morphology. Each criterion is assigned a weighted value reflecting its relative significance, and the combined analysis yields a priority index that supports decision-makers in identifying optimal sites for photovoltaic deployment. The methodology aims to reconcile the need for increased renewable energy production with broader environmental, social, and economic objectives, ensuring minimal conflicts with other land uses. By systematically evaluating risks such as flood vulnerability and slope instability, the framework facilitates the avoidance of high-risk zones. Furthermore, by considering variables like irradiation levels, land productivity, and ease of grid connection, it maximizes energy yields while limiting environmental impacts and infrastructural costs. This structured and transparent approach can guide regional authorities, urban planners, and private investors in implementing sustainable energy projects. The stakeholder perspective is integral to building consensus, facilitating more inclusive decision-making, and ensuring long-term acceptance and viability at the local level. This ultimately fosters more collaborative planning, aligning energy goals with societal and environmental demands
