    Making maps in Powerpoint and Word : why do regional scientists not map their results?

    Cartography has commonly been used in regional science and Exploratory Spatial Data Analysis is regularly applied to visualise the distribution of the variable of interest in space. Articles often contain several maps of administrative areas showing the values of a certain variable. However, and despite the benefits of such maps, they are nothing more than spatial catalogues of data. Their usefulness for regional scientist is beyond questioning, but the communicative value is limited. The rise of GIS has rightly been welcomed by many scientists, however, critical cartographers often pose the question if ‘GIS has killed cartography?’. Moreover, this discussion about maps in regional science can be more than a trivial item since it can reveal the fear of scientists to draw a conclusion. The chorematics approach, as developed by Brunet, considers maps as ‘vitrines’, and not as catalogues. In this paper we show that such an approach can enrich regional science by delivering a methodology to visualise spatial structures and dynamics using geometric figures. Finally, we argue that powerpoint and word are better cartographic tools than common GIS packages

    From GeoVisualization to visual-analytics: methodologies and techniques for human-information discourse

    2010 - 2011The objective of our research is to give support to decision makers when facing problems which require rapid solutions in spite of the complexity of scenarios under investigation. In order to achieve this goal our studies have been focused on GeoVisualization and GeoVisual Analytics research field, which play a relevant role in this scope, because they exploit results from several disciplines, such as exploratory data analysis and GIScience, to provide expert users with highly interactive tools by which they can both visually synthesize information from large datasets and perform complex analytical tasks. The research we are carrying out along this line is meant to develop software applications capable both to build an immediate overview of a scenario and to explore elements featuring it. To this aim, we are defining methodologies and techniques which embed key aspects from different disciplines, such as augmented reality and location-based services. Their integration is targeted to realize advanced tools where the geographic component role is primary and is meant to contribute to a human-information discourse... [edited by author]X n.s

    GEO-VISUALISATION AND VISUAL ANALYTICS FOR SMART CITIES: A SURVEY

    Get PDF
    Geo-Visualisation (GV) and Visual Analytics (VA) of geo-spatial data have become a focus of interest for research, industries, government and other organisations for improving the mobility, energy efficiency, waste management and public administration of a smart city. The geo-spatial data requirements, increasing volumes, varying formats and quality standards, present challenges in managing, storing, visualising and analysing the data. A survey covering GV and VA of the geo-spatial data collected from a smart city helps to portray the potential of such techniques, which is still required. Therefore, this survey presents GV and VA techniques for the geo-spatial urban data represented in terms of location, multi-dimensions including time, and several other attributes. Further, the current study provides a comprehensive review of the existing literature related to GV and VA from cities, highlighting the important open white spots for the cities’ geo-spatial data handling in term of visualisation and analytics. This will aid to get a better insight into the urban system and enable sustainable development of the future cities by improving human interaction with the geo-spatial data
