Indicators for monitoring the Sustainability of Transformations in Territorial Planning

This research aims to identify a set of indicators for the Abruzzo Region to monitor the sustainability of the transformations in territorial planning, in order to focus the “position” of the Region with respect to the goals of the National Sustainable Development Strategy (NSDS) and the 17 Goals of the 2030 Agenda. The proposed methodology consists of: a coherence analysis with the aim of verifying the existence of a convergence between the goals and the general strategies of the Abruzzo Region’s Plans, and the Goals/Principles of environmental sustainability derived from the NSDS; a recognition of the sustainability indicators already developed by various public/private institutions, at national level, in order to select the most suitable sustainable development indicators for the Abruzzo Region

Contributions à la géovisualisation pour l'intelligence territoriale

Ce travail de thèse de doctorat est placé dans le domaine de la Géovisualisation utilisé pour mettre en œuvre des systèmes de aide à la décision territoriale. Ce travail de recherche est né grâce à l'établissement d’un accord entre l’Université Tor Vergata de Rome, et l’INSA (Institut National des Sciences Appliquées), de Lyon. La co-tutelle de cette thèse est née pour la nécessité d’une approche multidisciplinaire à le sujet de recherche, en profitant des compétences en matière d'urbanisme, de l’environnement et de la modélisation de territoire à l'école doctorale ‘Geoinformazione’ de l'Université de Tor Vergata, et en utilisant d’avantage les compétences dans les systèmes d'information spatiale et de la géovisualisation au laboratoire LIRIS de l'INSA. Malgré ces avantages, l’un des problèmes les plus courants en visualisation de l’information est de représenter les données d’une manière claire et compréhensible. Actuallement il ya peu de fondations scientifiques pour guider les chercheurs dans la conception visuelle de données spatiales ; il existe des méthodes systématiques limitée pour évaluer l'efficacité des solutions proposées. Dans ce travail de recherche de doctorat, des contributions seront fournis à la création d'une méthode d'évaluation systématique pour évaluer et développer des affichages visuels efficaces. Dans ce contexte l’objectif de la recherche était de trouver une méthode simple et empirique - un test en ligne - qui pourrait être facilement reproductible pour differentes scenarios, pour soutenir l’administration publique dans différents contextes et pour différentes tâches.This PhD research work is placed in the domain of Geovisualization used to implement Territorial Intelligence and decision support systems. This research work was born through the establishment of an agreement between Tor Vergata University, Rome, and INSA (Institut National des Sciences Appliquées), Lyon. The co-supervision of this thesis was born from the necessity of a multidisciplinary approach to the research topic, taking advantage of the skills in urban planning, environment and territory modeling at the Geoinformation doctoral school of Tor Vergata University, and taking advantage of the skills in Spatial Information Systems and Geovisualization at the LIRIS Laboratory of INSA. The motivation that led us to deal with this research topic was the perception of a lack of systematic methods and universally approved empirical experiments in data visualization domain. The experiments should consider different typologies of data, different environmental contexts, different indicators and methods of representations, etc., in order to support expert users in decision making, in the urban and territorial planning and in the implementation of environmental policies. In modern societies, we have to deal with a great amount of data every day and Geovisualization permits the management, exploration and display of big and heterogeneous data in an interactive way that facilitates decision making processes. Geovisualization gives the opportunity to the user to change the visual appearance of the maps, to explore different layers of data and to highlight problems in some areas by the citizens. Despite these advantages, one of the most common problems in Information Visualization is to represent data in a clear and comprehensible way. Spatial data have a complex structure that includes spatial component, thematic attributes, and often the temporal component Actually there are limited scientific foundations to guide researchers in visual design of spatial data, and there are limited systematic and standard methods to evaluate the effectiveness of the solutions proposed. In this Phd research work, some contributions will be provided to the creation of a systematic assessment method to evaluate and to develop effective geovisualization displays. An empirical evaluation test is proposed to assess the effectiveness of some map displays, analyzing the use of three elements of visual design: 1. the spatial indicators to be represented and their context of visualization, 2. the physical dimensions of map displays, 3. the visual variables to represent different layers of information

A Test to Check the Efficiency of Visual Representation of Urban Data

International audienceInformation visualization is particularly interesting in the applications of Urban Information Systems (UIS). Spatial visualization of urban data permits a detailed analysis of different informative layers, and a graphic synthesis of territorial information, as a great amount of data can be visualized through spatial indicators and spatial representations. Although, cartographic representations of urban data can be really complex for a non-expert user, as they present different levels of information simultaneously and in a multi-dimensional context. In this paper, we present a test in order to verify the potentialities and the efficiency of visual representation in urban contexts. To attend this objective we propose different representations of an indicator (the passenger flow in a subway system), using different combinations of visual variables (J. Bertin, 1967); then we evaluate the number of errors in the interpretation of the maps. The analysis of test results provides indications about preferences and difficulties found in the interpretation of graphic representations in urban contexts. Our research aims to prove that the use of “smart visualization” can be very useful for scientific, public and business purposes. It is and will be a more and more important tool in the management of information and communication expecially for the development of smart cities

Evaluer, améliorer la visualisation des données spatiales, le cas des données urbaines ; Construction d’un test psycho-cognitif sur la représentation visuelle des indicateurs de flux

International audienceLa visualisation de l’information s’occupe des méthodes de présentation graphique des données et de la représentation visuelle des données spatiales. La conception de la visualisation de l’information est particulièrement intéressante dans les applications des Systèmes d’Information Urbains, étant donné que la grande quantité de données en milieu urbain peut être synthétisée et visualisée grâce à l’utilisation d’indicateurs spatiaux. La visualisation de l’information des zones urbaines est encore trop adressée à un public d’experts. Par la proposition d’un test sur la représentation visuelle des indicateurs spatiaux, cet article explore de nouvelles formes de représentation de données et les méthodes grâce auxquelles la visualisation de l’information urbaine peut devenir plus simple et permettre à tous, experts ou non, d’interpréter des cartes thématiques

Un test per verificare l'efficacia della rappresentazione visuale degli indicatori spaziali in ambito urbano

National audienceLa progettazione della visualizzazione dell’informazione è particolarmente interessante nelle applicazioni riguardanti i Sistemi Informativi Urbani. La rappresentazione paziale dei dati urbani permette sia un'analisi dettagliata dei diversi strati informativi, sia una sintesi grafica delle informazioni territoriali poiché grandi quantità di dati possono essere visualizzate mediante l’utilizzo di indicatori spaziali. Spesso, però, le rappresentazioni cartografiche proposte in ambito urbano, risultano complesse ad un osservatore non esperto, perché presentano contemporaneamente diversi livelli di informazione. In questo articolo si propone un test sulla appresentazione degli indicatori spaziali, per verificare l’efficacia e le potenzialità della rappresentazione visuale in ambito urbano. Per raggiungere questo obiettivo vengono proposte ad un panel di potenziali utilizzatori, diverse rappresentazioni cartografiche bidimensionali, e si verificano successivamente gli errori commessi nell’interpretazione delle mappe. Il test prevede la lettura di differenti rappresentazioni cartografiche di un indicatore spaziale (flusso di passeggeri tra due fermate di Metro) rappresentato in diversi momenti temporali, utilizzando le variabili visuali (J. Bertin, 1967) e le loro combinazioni. L’analisi dei risultati del test dovrebbe fornire alcune indicazioni relative alle preferenze e alle difficoltà riscontrate dagli utilizzatori nell’interpretazione delle rappresentazioni cartografiche in ambito urbano. La prosecuzione di questo test potrebbe riguardare la valutazione dell’efficacia delle rappresentazioni ridimensionali e animate (in particolare con variazione degli indicatori spaziali in tempo reale) e delle rappresentazioni interattive, nella gestione delle informazioni in ambito urbano
