InViTo - GeoVisualizzazione Interattiva a Supporto dei Processi di Decisione Territoriale
No full textLa tesi si inserisce in un filone della cartografia noto come "geovisualizzazione", che studia la visualizzazione interattiva dei dati territoriali come sistema di supporto per la pianificazione (PSS) e la decisione a tema territoriale (SDSS) (MacEachren, 2004; Andrienko et al., 2007). L'obbiettivo di questa tesi è la realizzazione di un metodo che sfrutti le capacità comunicative della visualizzazione per facilitare la costruzione di una conoscenza, alle diverse scale, del territorio attraverso la condivisione delle informazioni e l'interazione con le informazioni. La ricerca fin qui condotta ha portato alla strutturazione di un metodo denominato Interactive Visualization Tool (InViTo) che, tramite mappe dinamiche ed interattive, ambisce a supportare decisori e pianificatori nella comprensione e conoscenza delle relazioni di causa ed effetto che regolano le trasformazioni del territorio. InViTo è un metodo di elaborazione visiva dei dati che intende superare il concetto di "modello urbano" in favore di uno strumento che funzioni come semplice estensione delle capacità di calcolo del professionista. Esso è costruito con strumenti di uso comune tra i pianificatori e progettisti, quali Microsoft Excel, McNeel Rhinoceros e Grasshopper, Google Earth, e propone un sistema di supporto adattabile all'intero processo di decisione territoriale, basato su una struttura visiva, interattiva, flessibile, trasparente e con ridotti costi economici. InViTo è stato applicato in diversi casi studio, caratterizzati da diverse finalità, molteplici collaborazioni e differenti scale territoriali, passando da quella architettonica alla urbana e regionale fino alla transnazionale. In particolare, lo studio di InViTo è stato in gran parte realizzato presso SiTI, Istituto Superiore sui Sistemi Territoriali per l'Innovazione di Torino, ma è anche il frutto di una ricerca che ha visto la collaborazione a livello nazionale di ITHACA, Information Technology for Humanitarian Assistance, Cooperation and Action di Torino, Comune di Asti, Università di Roma "Tor Vergata", Politecnico di Milano, UnionTrasporti di Milano; e a livello internazionale di ETH di Zurigo (CH), Facoltà di Architettura della "University Sts. Cyril and Methodius" in Skopje (MK), Institute of Architecture and new Media della Graz University of Technology (A), Universiteit van Amsterdam (NL), University of Utrecht (NL), Port of Rotterdam (NL), Faculty of Sciences and Technology, University of Coimbra (P), Planungsverband Ballungsraum Frankfurt/Rhein-Main (D), Verband Region Rhein-Neckar (D). L'applicazione di InViTo durante workshop con professionisti di diversa provenienza, ha evidenziato la sua flessibilità ad adattarsi a diversi obiettivi e la sua efficacia nel supportare la discussione e i ragionamenti a tema territoriale. Al momento, si ipotizzano, quali elementi potenziali di sviluppo, i seguenti: la costruzione di un'interfaccia utilizzabile da persone non esperte, l'introduzione della dimensione temporale, l'estensione delle modalità di partecipazione degli utenti verso periferiche per l'interazione individuale col modello e, in particolare, la migrazione verso una piattaforma we
Comparing Traditional Maps with Twitter-Derived Maps: Exploring Differences and Similarities
Full text linkThe paper describes the use of quantitative data obtained from the social medium Twitter to analyse urban patterns. A case study in the urban neighbourhood of Pampulha, Belo Horizonte, Brazil, is described to show the outcomes of a comparative analysis with traditional data used in the urban and transport planning processes of the city. The maps derived from the elaboration of Twitter data are overlapped to traditional maps providing evidence of similarities and differences. The paper illustrates the outcomes of this overlapping and discusses the possibilities given by the use of freely and quickly available data instead of costly but official dat
Managing urban data through a web-based platform: The newer Interactive Visualisation Tool (InViTo)
Full text linkDetecting spatial features from data-maps: the visual intersection of data as support to decision-making
Full text linkThe assessment of spatial systems can be supported by the analysis of data coming from different sources and describing different aspects such as economic, social, environmental, energy, housing or mobility issues. Nevertheless, the analysis of such a large amount of data is difficult. In order to improve the readability of data also with non-technicians, new methods of communication are needed, which could facilitate the sharing of information among people with different skills and backgrounds. In this context, the paper shows the developments in geo-visualisation to support and improve the processes of planning and decision-making. First, the use of a map-based visualisation is suitable for intuitively understanding the location and distribution of specific elements. Second, the graphic interface can be used to drive users in the investigation of data. It can provide a linear method that is more comprehensive to the human mind in dealing with the complexity of spatial systems. In addition, the possibility to select and filter data by single attributes allows databases to be explored interactively and read by differently skilled users. The intersection and overlapping of information enables users to discover the relationships between data, the inefficiencies and critical areas, thus providing suggestions for further reasoning in planning and decision-making. Furthermore, collaborative and participatory sessions require quick answers and simple readability. Thus, the real time response to simple queries widens the opportunities for improving the discussion. A case study describes the methodology used for sharing the data collected during an Interreg IVB NWE Project named "CoDe24" (INTERREG IVB NWE, 2005; ERDF European Territorial Cooperation 2007-2013, 2010). By the use of a web-GIS visualisation tool, namely GISualisation, the project partnership was allowed to explore the data concerning the railways and train typologies along the Genoa-Rotterdam corridor. Despite the high factor of usability of the tool, it was not employed much by participants to the project so that further reasoning is needed to evaluate how digital tools are perceived by professionals
Dynamic maps for supporting spatial decision processes
Full text linkThe research here described aims at supporting decision making processes related to large scale and long term spatial questions. It proposes a method for sharing information and conveying reasoning by the use of dynamic maps. Through the visual localization of costs and benefits, the participants to the spatial decision processes are led to evaluate methods and objectives for a lot of alternative development options. The system has been used in different case studies showing its effectiveness in creating awareness on spatial problems and enabling discussions
GISualisation: a tool for visually supporting planning processes
Full text linkThe evaluation of quality of life in cities can be supported by the analysis of data coming from different sources and describing different aspects such as economic, social, environmental, energy, housing or mobility issues. Nevertheless, the analysis of such big amounts of data is difficult so that only expert technicians can access to their inner contents. Furthermore, the outcomes of these analyses are often presented in static outcomes which reproduce the reasoning of technicians who have not expertise in urban studies. Thus, planners and decision-makers have to base their own choices on given outcomes without opportunities for personally investigating the inner contents of data. In order to facilitate the data exploration and readability by non-technicians, a GIS-based visualization tool, namely "GISualisation", has been realized to give to both planners and actors involved in planning processes, a decision support system useful to visualize the inter-relations between data which describe cities. The tool is a web-based interactive visual tool, which works on geo-referenced dynamic maps, currently created with free Web GIS applications. GISualisation displays data on a map and offers the possibility to select and filter data by single attributes, allowing users to interact readily with large databases and customise the visualisation of information. Thus, the tool offers a simple interface to visualise GIS data on the basis of users' requests, providing a support for planners and decision-makers to explore data and detect issues of inefficiency, ineffectiveness or critical areas which needs further reasoning on their planning or design. Furthermore, it can be used in collaborative and participatory session so to improve the information sharing among participants. Depending on the case study, the tool can be adapted and customized to visualise different type of data, ensuring user-friendliness and possibility to explore the relationships between data. GISualisation has already been applied in investigating inefficiencies in a public transport system (Pensa, Masala, Arnone, & Rosa, 2013), in studying pedestrian paths in an urban area, in analysing urban population health and in the evaluation of social housing projects. Further developments will include the integration with the interactive Visualisation Tool (InViTo) (Pensa, Masala, & Lami, 2013; Pensa & Masala, 2014) and the possibility to include real-time data feeds. Through GISualisation, data on quality of life can be investigated and visually analysed so to offer a new tool to actors involved in planning process for detecting critical areas and improving the urban planning proces
The version of InViTo designed for Asti: maps and results
No full textOnce the Asti case study was set up, InViTo could produce different typologies of interactive visualisations according to the expertise level of viewers. The use of dynamic outcomes enhances the participation and collaboration of the actors involved, who can modify a number of parameters and see the consequent effects in real time. At the same time, maps and visual outputs provide useful information for generating the guidelines of new projects in the studied areas, also by means of scenario compariso
Interactive Visualization Tool (InViTo)
No full textThe instrument developed by SiTI, called InViTo (acronym of Interactive Visualization Tool), aims to provide a visual interactive support to large scale planning processes. The tool is intended to provide an effective basis for sharing information and enabling discussion among different actors such as planners, stakeholders and, in general, nonexpert people within focus groups, workshops, participative and collaborative processes. The decision to develop this instrument stems from the need to analyse the relations between urban development and spatial elements, such as transport facilities or landscape issues. Since accessibility is one of the factors which most influence location choices, a specific study has been dedicated for its investigation. The main strength of InViTo is represented by the possibility of managing interactive and dynamic scenarios, in order to visualize in real time the effects of decision making on urban form and to support the planning processes. Due to its flexibility, the tool can be used for several applications and in different fields of research which need to visualize geo-referenced data on maps. In this COST Action, InViTo is presented as a tool for calculating and visualizing accessibility in real time during participated planning processe
