[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) In the context of the personalization of map design, cartographic needs have been highlighted considering the handling of more artistic and expressive tools, in order to design stylized and expressive maps, in existing cartographic pipelines. Based on previous works on style formalization, an approach of the specification of the style of a map has been proposed and experimented for some use cases. A first step concerns the analysis of inspiration sources, in order to extract "what does make the style of the source"™, i.e. the salient visual characteristics to be automatically reproduced (textures, spatial arrangements, linear stylization, etc.). In order to mimic and generate those visual characteristics, existing and innovative rendering techniques have been implemented in our GIS engine, thus extending the capabilities to generate expressive renderings. Therefore, an extension of the existing cartographic pipeline has been proposed based on the following aspects: 1- extension of the symbolization specifications OGC SLD/SE in order to provide a formalism to specify new types of Symbolizers and their related rendering methods; 2- separate specification of each rendering method and its parametrization, as metadata. The main contribution has been described in (Christophe et al. 2016). We focus here on the extension of the cartographic pipeline (SLD++ and metadata) and the diversity of map design capabilities that have been experimented for many topographic styles: old cartographic styles (Cassini), artistic styles (watercolor, impressionism, Japanese print), hybrid topographic styles (ortho-imagery & vector data) and finally abstract and photo-realist styles for the geovisualization of costal area. The genericity and interoperability of the approach is promising and has already been tested for 3D visualization.

[Termes IGN] symbology encodingRésumé : (auteur) This presentation paper resumes recent results on an extension of the cartographic pipeline in GIS to integrate expressive rendering techniques, in order to increase the aesthetics and expressivity of maps. They are implemented in the form of shaders which can be called and parameterized from a style file following the OGC style specifications. We propose an extension of the OGC Symbology Encoding specification.

[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.

[Termes IGN] Web Map ServiceRésumé : (Auteur) The traditional cartographic workflow is highly dependent on manual or semiautomatic data selection and symbolization. In an era where computer automation is part of our everyday life, the issue of automatically creating high quality maps from GIS content is still very challenging and time-consuming, and this in spite of the power of Web and database technologies. Moreover, many decisions must be taken on short notice based on cartographic visualizations, for instance in the field of risk management. The above considerations shape the motivation of this thesis. Inspired from the current developments in the field of Cartography and GIS, electronic atlases and map representation definitions such as CartoML, DiaML and Symbology Encoding (SE), this work introduces the generic concept of cartographic Web services as a method for Web Cartography. The thesis proposes the Cartographic Web Services (CartoWS) as a solution for automatically producing maps from geodata based on a generic and expressive map representation. The maps are obtained from GIS data as geo-referenced output images via a Web-based interface. As previously mentioned, the concept of cartographic web services relies on the map representation. This work defines a map representation adapted for the needs of cartography. The map representation is a formal description of the map that coordinates all aspects of transforming the GIS data into the map image, including geographical bounds, scale selection and, most important, the symbolization. It is based on the OGC standards Styled Layer Descriptor (SLD) and Symbology Encoding (SE). Generic symbols, diagrams, filtering or masking rules are also defined to be compatible with current OGC standards. Moreover, the inclusion of GIS functionalities such as intersection, union and difference in the map representation process allows for a precise differentiation in the symbolization of features, that otherwise would be possible only by preprocessing the data. The generic concept of CartoWS is specified by the Map and Diagram Service Interface (MDSI). Making use of specific computer science knowledge, such as Web services and their mechanism, concepts and properties, it is specified the interface that details the operations of CartoWS. The definition of the MDSI follows and enhances the Web Map Service (WMS) standard. The QGIS map server is the software implementation of the MDSI. Furthermore, the QGIS map server demonstrates the utility of CartoWS by proof-of-concept applications. The proposed Cartographic Web Services offer functionalities that support the development of cartographic applications on the Web. A Service Oriented Architecture (SOA), like the one recommended for the CartoWS usage, is the basis for many competitive internet-ready applications, specifically for the creation of dynamic Web resources. On the basis proposed in this thesis, future research may consider a closer cooperation between Cartography and GIS, especially regarding the development of Web-based cartographic applications and Web GIS.
