Several of the CORINE land cover classes are more accurately described as 'land use' classes, (e.g. airports and construction sites). Since a land cover class (as identified on the LCMGB) could be related to several uses, the CORINE land use classes had to be identified separately from the CORINE land cover classes, within the generalization procedure. This was done using traditional methods of visual image interpretation, combined with the extensive use of ancillary land use information. The interactive creation of the land use classes described in this paper is the main component that did not use wholly automated methods; 95% of the CLCMGB was created using automated methods. This paper describes the mapping of the land use classes in detail.

The UK land cover map 2000: construction of a parcel-based vector map from satellite images / R.M. Fuller in Cartographic journal (the), vol 39 n° 1 (June 2002)  

Public [article]  inCartographic journal (the) > vol 39 n° 1 (June 2002) . - pp 15 - 25 Titre : The UK land cover map 2000: construction of a parcel-based vector map from satellite images Type de document : Article/Communication Auteurs : R.M.

The map updates and substantially upgrades the Land Cover Map of Great Britain (LCMGB), made in 1990-92. This paper outlines the character of the map through a description of its specification, production and outputs. The paper is aimed at users of LCM2000 and derived data who need to understand more of the map and its characteristics. The paper also outlines plans for making data available to researchers and applied users. The most important development in LCM2000 was the spectral segmentation of images to generate vector land parcels. Land cover was then identified by the spectral classification of the image data in these parcels. Classification used specially developed procedures which exploited known spatial, spectral and contextual characteristics of land cover. The resultant GIS incorporates, within its vector structure, detailed attribute data which record parcel-based land cover, plus information on class probabilities, data on withinparcel heterogeneity, information on landscape structure and context, cover information from LCMGB, together with a record of each parcel's processing history.

Integration methodologies for interactive forest modelling and visualization systems / H. Tang in Cartographic journal (the), vol 39 n° 1 (June 2002)  

Public [article]  inCartographic journal (the) > vol 39 n° 1 (June 2002) . - pp 27 - 35 Titre : Integration methodologies for interactive forest modelling and visualization systems Type de document : Article/Communication Auteurs : H.

Bishop, Auteur Année de publication : 2002 Article en page(s) : pp 27 - 35 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] modélisation [Termes IGN] outil d'aide à la décision [Termes IGN] sylviculture [Termes IGN] système d'information géographique [Termes IGN] visualisation cartographique Résumé : (Auteur) GIS, environmental modelling and visualization techniques are increasingly being used together in environmental and forest management practices as decision support tools. There are many attempts to produce better integration of these techniques, especially advanced visualization techniques. This paper begins with the brief review of visualizations currently used in forest management, and then examines existing systems using those visualizations. An idealized forest decision support system is then proposed. The trend for spatial decision support system (SDSS) development is the integration of GIS, modelling and visualisation. This paper classifies integration methodologies in terms of integration techniques applied and summarizes their advantages and disadvantages. Each approach is then compared based on the degree of interactivity, level of integration, and implementation effort required. The paper also describes and presents the results of several system developments attempted by the authors and briefly discusses the issues considered in their development and evaluation.

An automated multi-criteria cartographic aid for point annotation / F.T. Huffman in Cartographic journal (the), vol 39 n° 1 (June 2002)  

Public [article]  inCartographic journal (the) > vol 39 n° 1 (June 2002) . - pp 51 - 64 Titre : An automated multi-criteria cartographic aid for point annotation Type de document : Article/Communication Auteurs : F.T. Huffman, Auteur ; R.G. Cromley, Auteur Année de publication : 2002 Article en page(s) : pp 51 - 64 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] analyse multicritère [Termes IGN] placement automatique des écritures Résumé : (Auteur) Mathematical algorithms for placing labels upon maps have been used for the past thirty years. This paper presents a multicriteria model for point feature annotation that examines the sometimes conflicting issues in the point labelling process. Based on a maximum labelling model, the primary goal is to place the maximum number of labels on the map, although secondary goals reflect other considerations such as point size, position preferences, and feature importance. By differentially weighting these separate factors, emphasis could be placed on each consideration in turn allowing the cartographer to assess the implications of each factor in the point annotation process. An application of this model to mountain peaks in Grand Teton National Park illustrates how it can assist a cartographer as a preliminary step in assessing the difficulty encountered in labelling point symbols as well as providing the cartographer with a choice of alternative scenarios upon which to base the final placement.

Cognitive geometry for cartography / J. Comenetz in Cartographic journal (the), vol 39 n° 1 (June 2002)  

Public [article]  inCartographic journal (the) > vol 39 n° 1 (June 2002) . - pp 65 - 75 Titre : Cognitive geometry for cartography Type de document : Article/Communication Auteurs : J. Comenetz, Auteur Année de publication : 2002 Article en page(s) : pp 65 - 75 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] classification dirigée [Termes IGN] géométrie [Termes IGN] système d'information géographique [Termes IGN] visualisation cartographique Résumé : (Auteur) The standard model of the geometry of cartographic visualization in geographic information systems (GISs) is based on the classification of cartographic objects into points, lines, and polygons, represented with zero, one, and two dimensional symbols. This is restrictive because an object or symbol may actually span more than one of these dimensional categories or may occupy an intermediate position between categories. A more complete, 'cognitive' model of the geometry of visualization is proposed here. The new model is more flexible because it permits a symbol or object to be positioned anywhere within several continua between the standard dimensional categories.
