4 Expertise et SPAtialisation des Connaissances en Environnement Expertise and Spatializing of Environmental Knowledge 4

5 Representation and availability of environmental knowledge to help a sustainable development Develop the ability to acquire, to process and to diffuse remote sensing data. Develop methods to integrate and to make available multi-disciplinary ability for environment. mplementation of methods to spatialize knowledge available in the decision process. Organize transfer and educational operations Geodata Acquisition Spatializing methods Sspatio-temporal multi-scale approach SPAAL x SPECRAL x EMPORAL Capitalization and integration of knowledge System approach Availability of knowledge Education & transfer Projects with partners 5

6 A positioning at the interface of environmental sciences, spatial technologies and information technologies 80% of future spatial environmental data (space agency) nformation echnologies Capitalization & nteroperability using standard (system maturity) Evolution toward integration of distributed knowledge Social Sciences, Geology, Oceanography, Botany, Hydrology,... Environment and usages Spatial echnologies Realization of the society, evolution of responsability and issues. Adjustment of spatial, spectral and temporal dimension to real problem. 6

16 Mathematics/Computer sciences and environment? Work on methods for environment, it is problems about : access to distributed, heterogeneous, multi-source data integration of geographical data, satellite data, real-time sensor management of temporal and multi-scale data management of incomplete data representation of multi-disciplinary knowledge decision support multi-partners applications A wide area for research and engineering in mathematics and computer science 16

17 Research directions ew architecture for Geographic nformation Systems : Use of open standard W3C, OpenGS Consortium Use of metadata SO Evolution to web services ==> interoperable services with data catalog to product, to publish, to search, to use data on the web From data and services to knowledge : semantic web metadata, reasoning, ontology ==> geographic semantic web 17

18 Semantic web im Berners-Lee «Axioms, Architecture and Aspirations» W3C all-working group plenary Meeting February 2001 rust Proof Logic Ontology Vocabulary RDF + RDF Schema Digital Signature XML + S + XML Schema Unicode UR 18

19 Research directions Knowledge representation : multi-agents systems, neural networks, bayesian networks, logic, conceptuel graph and semantic networks, constraint programming, model-checking for dynamic system,... Cooperation of distributed applications 19

27 Assessment from previous projects ecessity to access data from different sources Many partners (service company, administrations, research institute, ) Different working methods Differents software Differents places Heteroneneous data, format and systems A large part of time is used to search, to obtain, to convert and to integrate data Centralized data ecessity to general use of standards 27

28 Use of open standards n the domain of the internet : World Wide Web Consortium (W3C) Extensible Markup Language (XML) n the domain of geospatial information : nternational normalisation : the echnical Comity SO 211 the standardisation in the field of digital geographic information ndustrial standardisation : the OpenGS consortium the definition of specification to define transparent access to heterogeneous geodata and geoprocessing resources in a networked environment Geographic Markup Language (GML) 28

29 Use of Metadata Data about data ecessary to know what data exist, their quality,... Use of standard for metadata : SO ==> to define a catalog of available data 29
