GIS Infomobility for Travellers
2016
Geographical Information Systems (GIS) are essential systems to support decisions on territorial and environmental aspects. But they not always have been properly used for this purpose. Only in recent years GIS have been getting better used for the planning, management and control of the territory. The application of GIS to the transport sector has become relevant both for management and decision-making in support of Public Administration (PA) and citizens. GIS are particularly useful for roads and routing graphs management capabilities as well as for searching the most suitable path. The results achieved in this research activity aimed to evaluate different road graphs, proprietary and fre…
Towards Digital Twinning on the Web: Heterogeneous 3D Data Fusion Based on Open-Source Structure
2023
Recent advances in Computer Science and the spread of internet connection have allowed specialists to virtualize complex environments on the web and offer further information with realistic exploration experiences. At the same time, the fruition of complex geospatial datasets (point clouds, Building Information Modelling (BIM) models, 2D and 3D models) on the web is still a challenge, because usually it involves the usage of different proprietary software solutions, and the input data need further simplification for computational effort reduction. Moreover, integrating geospatial datasets acquired in different ways with various sensors remains a challenge. An interesting question, in that r…
UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
Construction of a webgis tool based on a gis semiautomated processing for the localization of p2g plants in sicily (Italy)
2021
The recent diffusion of RES (Renewable Energy Sources), considering the electric energy produced by photovoltaic and wind plants, brought to light the problem of the unpredictable nature of wind and solar energy. P2G (Power to Gas) implementation seems to be the right solution, transforming curtailed energy in hydrogen. The choice of the settlement of P2G plants is linked to many factors like the distances between the gas grid and the settlement of RES plants, the transportation networks, the energy production, and population distribution. In light of this, the implementation of a Multi-Criteria Analysis (MCA) into a Geographic Information System (GIS) processing represents a good strategy …

OPEN GEONET: WebGIS Open Source of a GNSS Permanent Network
2010
In Sicily, from 2005 to 2007, a research group at Dipartimento di Rappresentazione (DIRAP), University of Palermo, Italy, has realized a Global Navigation Satellite System (GNSS) Network Real Time Kinematic (NRTK), project inside the “National Interest Research Program” PRIN2005 entitled ”Reti di stazioni permanenti per impieghi di controllo ed emergenza” founded by Minister of Instruction, University and Scientific Research (MIUR). With the rapid development of Internet and Web, Web Geographical Information System became an important aspect of GIS study. WebGIS software allow the most efficient and low-cost way in dissemination and sharing of geographic information for public and specific …
Un WEBGIS Open Source a supporto dei rilievi GPS in Sicilia
2011
Con il rapido sviluppo di Internet, degli ultimi anni, i sistemi informativi geografici basati sull’utilizzo del Web sono diventati un argomento di forte interesse per il settore dei GIS. Il WEBGIS è uno strumento software, basato su sistemi di reti locali o geografiche e su un’interfaccia semplificata operante tramite browser Internet, che permette l’accesso a banche dati geografiche, anche a persone non esperte del settore. Tramite tale strumento è possibile visualizzare contestualmente informazioni geografiche organizzate su livelli informativi tematici, anche caratterizzati da diverso sistema di riferimento geografico ed eseguire, tramite un’interfaccia Web semplificata, parte delle ope…
3D DATA INTEGRATION FOR WEB BASED OPEN SOURCE WebGL INTERACTIVE VISUALISATION
2022
Abstract. Recent advances in open-source geospatial technologies in WebGIS allowed the visualization of a 3D complex environment on the web, exploiting realistic Globe reproduction of the real territorial asset. At the same time, in the field of gaming technologies, the new possibilities offered by open-source WebGL JavaScript libraries allowed the creation of Virtual Reality navigation models on the web. The integration between 3D GIS globe navigation models and VR environment navigation is a solution that offers a further level of detail in web navigation, exploiting the capabilities of web browsers in the best way. This research further contributes to this field, showing a workflow to in…
OPENSIRACUSA. Una piattaforma WebGIS interoperabile per la tutela, la valorizzazione e la fruizione dei Beni Culturali
Siracusa possiede un ingente patrimonio archeologico e culturale, posto oggi a testimonianza di una delle più grandi e potenti città dell’Occidente antico e giunto a noi tramite complessi meccanismi di stratificazione archeologica e architettonica e in seguito a ripetuti processi di espansione e contrazione del centro abitato nel corso dei secoli. Questo immenso patrimonio, variamente conservato all’interno del tessuto urbano moderno, tuttavia, ha dovuto e deve fare ancora oggi i conti con numerose criticità che rischiano di minarne inevitabilmente la conoscenza, la comprensione e la stessa salvaguardia. In tale quadro nasce OpenSiracusa, un progetto di archeologia pubblica volto alla creaz…
Paleocarta del Valdarno: esperienze di valorizzazione del territorio
2019
Le faune fossili plio-pleistoceniche del Valdarno (Toscana, Italia centrale) costituiscono un patrimonio di grande importanza storico-scientifica. Al fine di favorire l’accesso della collettività alle faune del Valdarno Superiore custodite presso il Museo Paleontologico di Montevarchi (Arezzo), sia al pubblico generale che agli specialisti, è stata studiata e sviluppata la Paleocarta del Valdarno Superiore, un progetto basato sulla piattaforma Google Maps e sul software gratuito Qgis. Il progetto ha portato alla costruzione di due carte geografico-paleontologiche, suddivise a loro volta nei tre diversi momenti di popolamento del Valdarno. The Upper Pliocene – Lower Pleistocene faunas of Val…
