[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.

[Termes IGN] web sémantiqueRésumé : (Auteur) Discovery of suitable web services is a crucial task in Spatial Data Infrastructures (SDI). In this work, we develop a novel approach to the discovery of geoprocessing services (WPS). Discovery requests and Web Processing Services are annotated as conjunctive queries in a logic programming (LP) language and the discovery process is based on Logic Programming query containment checking between these descriptions. Besides the types of input and output, we explicitly formalise the relation between them and hence are able to capture the functionality of a WPS more precisely. The use of Logic Programming query containment allows for effective reasoning during discovery. Furthermore, the relative simplicity of the semantic descriptions is advantageous for their creation by non-logics experts. The developed approach is applicable in the Web Service Modeling Framework (WSMF), a state-of-the-art semantic web service framework.

[Termes IGN] standard OGCRésumé : (Auteur) Open source software offers freely available source code to the general public, thereby allowing for modifications and redistribution. Freedom to modify source code offers significant opportunities in the establishment of a Europe-wide spatial information infrastructure. The INSPIRE directive provides a legal framework for the establishment of a spatial information infrastructure across the European Union. This article describes a study on open source tools for the handling of INSPIRE-conformant data as carried out by the GIS4EU project. A case study is presented based on extension of the OpenJUMP workbench for downloading and displaying INPIRE-conformant data.

[Termes IGN] Web Coverage ServiceRésumé : (Auteur) Imagery is more and more becoming integral part of geo services. More generally, an increasing variety of sensors is generating massive amounts of data whose quantized nature frequently leads to rasterized data structures. Examples include 1-D time series, 2-D imagery, 3-D image time series and x/y/z spatial cubes, and 4-D x/y/z/t spatio-temporal cubes. The massive proliferation of such raster data through a rapidly growing number of services make open, standardized service interfaces increasingly important. Geo service standardization is undertaken by the Open GeoSpatial Consortium (OGC). The core raster service standard is the Web Coverage Service (WCS) which specifies retrieval based on subsetting, scaling, and reprojection. In 2008, OGC has issued a companion standard which adds flexible, open-ended coverage processing capabilities. This Web Coverage Processing Service (WCPS) specifies a coverage processing language allowing clients to send requests of arbitrary complexity for evaluation by the server. This contribution reports on the WCPS standard by giving an introduction to its coverage model and processing language. Further, design rationales are discussed, as well as background and relation to other OGC standards. 1-D to 4-D use case scenarios illustrate intended use and benefits for different communities. Although the paper focuses on conceptual issues, the WCPS reference implementation, PetaScope, is briefly addressed. The author is co-chair of the coverage-related working groups in OGC.

[Termes IGN] Web Map ServiceRésumé : (Auteur) The increased popularity of standards for geospatial interoperability has led to an increasing number of geospatial Web services (GWSs), such as Web Map Services (WMSs), becoming publicly available on the Internet. However, finding the services in a quick and precise fashion is still a challenge. Traditional methods collect the services through centralized registries, where services can be manually registered. But the metadata of the registered services cannot be updated timely. This paper addresses the above challenges by developing an effective crawler to discover and update the services in (1) proposing an accumulated term frequency (ATF)-based conditional probability model for prioritized crawling, (2) utilizing concurrent multi-threading technique, and (3) adopting an automatic mechanism to update the metadata of identified services. Experiments show that the proposed crawler achieves good performance in both crawling efficiency and results' coverage/liveliness. In addition, an interesting finding regarding the distribution pattern of WMSs is discussed. We expect this research to contribute to automatic GWS discovery over the large-scale and dynamic World Wide Web and the promotion of operational interoperable distributed geospatial services.
