[Vedettes matières IGN] GéovisualisationRésumé : (auteur) Mountain maps were the result of hours of precise by-hand drawing reliefs, based on perceptive and carto-graphic rules. Now, we would like to experiment automated methods in order to generate those very expressive drawings and to make the terrain morphology perceptible. It would also be a way to be able to control possible car-tographic styles for mountain map design. A method of automated texture generation has been proposed and extend-ed for cartography in (Loi et al. 2013, Loi, 2015). Iterations between cartographers and researchers in GISciences and Computer graphics allow experimenting and specifying various data and rules in order to influence the texture generation for terrain perception. The method is very promising, in order to be used in existing expressive carto-graphic pipelines, and can be subtly controlled to generate various types of textures for other expressive cartographic styles.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) Cartographic design requires controllable methods and tools to produce maps that are adapted to users’ needs and preferences. The formalized rules and constraints for cartographic representation come mainly from the conceptual framework of graphic semiology. Most current Geographical Information Systems (GIS) rely on the Styled Layer Descriptor and Semiology Encoding (SLD/SE) specifications which provide an XML schema describing the styling rules to be applied on geographic data to draw a map. Although this formalism is relevant for most usages in cartography, it fails to describe complex cartographic and artistic styles. In order to overcome these limitations, we propose an extension of the existing SLD/SE specifications to manage extended map stylizations, by the means of controllable expressive methods. Inspired by artistic and cartographic sources (Cassini maps, mountain maps, artistic movements, etc.), we propose to integrate into our system three main expressive methods: linear stylization, patch-based region filling and vector texture generation. We demonstrate how our pipeline allows to personalize map rendering with expressive methods in several examples.
