Visualisation as a support to spatial decision processes: some considerations on the concepts behind the construction of a strategy image
No full textThe knowledge of a territory is the first step for its management and strategic planning. The drawing of space is historically the method for achieving its knowledge, so that the visualisation of a territory becomes essential to its planning. Information Technologies (IT) provide nowadays new opportunities to enhance the process of knowledge building and sharing by means of spatial data visualisation. In this context, this chapter introduces the historical concept behind the production and perception of spatial data visualisation and proposes it as a support to decision making related to spatial issue
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
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
La visualizzazione storica degli edifici industriali
No full textThe article considers the methods for representing and communicating the results of a research conducted by the Polytechnic of Turin DIPRADI on the urban area named "Spina3" and "Spina 4". The construction of a three-dimensional model and its publication on the Web suggested different questions. On the technological side, the choice of Google Earth and Panoramio highlighted problems with the display of large areas, in different historical steps, and showed the need of an interface able to guide users in exploring a wide range of information. From the point of view of a conceptual approach, the open access Web to the network of academic knowledge has revived the topic concerning the effects and strategic implications of information disseminatio
Detecting 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
