In order to support such a process on the fly, we propose a generalization approach based on self-generalizing objects (SGOs) that encapsulate geometric patterns (forms common to several cartographic features), generalization algorithms, and spatial integrity constraints. During a database enrichment process, an SGO is created and associated with a cartographic feature or a group of features. Each SGO created is then transformed into a software agent (SGO agent) in a multi-agent on-the-fly map-generalization system. SGO agents are equipped with behaviours that enable them to coordinate the generalization process. This article presents the concept of the SGO and two prototypes developed to support this approach: a prototype for the creation of SGOs and another for the on-the-fly map generalization (which uses the created SGOs).

Proposed cartographic design principles for 3D maps: a contribution to an extended cartographic theory / C. Häberling in Cartographica, vol 43 n° 3 (September 2008)  

Public [article]  inCartographica > vol 43 n° 3 (September 2008) . - pp 175 - 188 Titre : Proposed cartographic design principles for 3D maps: a contribution to an extended cartographic theory Type de document : Article/Communication Auteurs : C.

Nevertheless, aspects of the design of such views and of their impact on readers have rarely been investigated in cartographic research. The establishment of cartographic design principles is missing, to a large extent. Within the framework of a research project, propositions for such principles were derived by evaluating settings and options for specific graphic variables. Based on an inventory of design aspects and graphic variables for 3D maps, selected cues for two major design aspects (degree of abstraction and size of map objects) and five different graphic variables (viewing inclination, zoom factor, light direction, haze density, and sky structure) were evaluated by means of 3D map examples and expert interviews. A set of cartographic design principles was derived from this evaluation and proposed for more detailed user tests. The proposed design principles could also be seen as the beginning of a framework to extend cartographic theory and assist map authors in the iterative design process.

The natures of maps : cartographic constructions of the natural world / Denis Wood in Cartographica, vol 43 n° 3 (September 2008)  

Public [article]  inCartographica > vol 43 n° 3 (September 2008) . - pp 189 - 202 Titre : The natures of maps : cartographic constructions of the natural world Type de document : Article/Communication Auteurs : Denis Wood, Auteur ; John Fels, Auteur Année de publication : 2008 Article en page(s) : pp 189 - 202 Langues : Anglais (eng) Descripteur : [Termes IGN] carte [Termes IGN] cognition [Vedettes matières IGN] Cartologie Résumé : (éditeur) We are pleased to introduce a new section in Cartographica devoted to a series of invited critiques and commentary on a target article. For the inaugural contribution, we have chosen to examine chapter 1 of a new book by Denis Wood and John Fels, The Natures of Maps (University of Chicago Press, 2008). Responses to this piece have been provided by Chris Perkins (University of Manchester, UK), Gwilym Eades (McGill University, Montreal, Canada), and Rob Kitchin (National University of Ireland, Maynooth). Wood and Fels then offer a short reply. Note that, for reasons of space and of clarity, some notes have been modified in the version provided here, and the colour figures that appear in the book have been omitted. Except in quoted material, US spellings have been replaced by Canadian spellings. (Jeremy W. Crampton).
