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

Propuesta de un modelo geográfico desde un enfoque de ciudad-región: El caso del municipio de Montería- Colombia (2020)

The objective of this article was to propose a territorial organization model for the municipality of Monteria (Colombia) from the city-region approach and corematic. Methodologically, a bibliographic review was made on territorial models through chorems, as ways of synthesizing statistical, heuristic and design information in schemes; The cartographic base of the municipality was taken, with which the delimitation of the study area was made, the territorial dynamics were identified by adapting what was proposed by the basic authors Breheny and Rookwood (1994) and Ravetz (2000) with the information available. Based on physical-natural, social, economic and land use variables, the homogeneous regions that are finally schematized in the chorem were determined. This article resulted in a proposal for territorial organization through a city-region model that shows the structure of the territory in areas with homogeneous characteristics in their interior but differentiated from the rest, which facilitates their understanding and serves as a basis for their subsequent use in territorial planning instruments.Este artículo tuvo como objetivo proponer un modelo de organización territorial del municipio de Montería (Colombia) desde el enfoque de ciudad región y la coremática. Metodológicamente se hizo una revisión bibliográfica sobre modelos territoriales a través de coremas, como las formas de sintetizar la información estadística, heurística y de diseño en esquemas; se tomó la base cartográfica del municipio, con la que se realiza la delimitación del área de estudio, se identificaron las dinámicas territoriales adaptando lo propuesto por los autores de base Breheny y Rookwood (1994) y Ravetz (2000) con la disponibilidad de información. A partir de variables físico-naturales, sociales, económicas y usos del suelo se determinaron las regiones homogéneas que finalmente se esquematizan en el corema. Como resultado se generó una propuesta de organización territorial a través de un modelo de ciudad región que muestra la estructura del territorio en áreas con características homogéneas en su interior, pero diferenciadas con el resto; lo que facilita su comprensión y sirve como base para su posterior utilización en instrumentos de planeación territorial

A Primer of Geographic Databases Based on Chorems

International audienceThe goal of this paper is not to present outcomes of research, but rather present a new research plan in the use of chorems in geographic information systems. Created by R. Brunet, chorems are a schematic representation of a territory. Presently, geographic decision-makers are not totally satisfied by conventional cartography, essentially because they want to know where and what are the problems. And so chorems appear as an interesting approach to unveil geographic problems, and so to help decision makers understand their territory, their structure and their evolution. After having given the definition and presented some applications of chorems, we show how chorems can be discovered by spatial data mining, can help decision making, and also how chorem maps can be a novel approach to visually entry a geographic database or datawarehouse. Comparing with the Ben Shneiderman’s approach, chorems can give an overview of the territory; then by zooming and filtering, and sub-chorem maps can be generated for smaller territories. Finally a list of barriers to overcome is given as main landmarks for a new research program in order to design new kind of geographic information systems or spatial decision support systems
