1 Sextant On-Line information system for marine geographical information E. Quimbert, M. Bellouis, F. Lecuy, M. Treguer Centre de Bretagne BP 70, Plouzané France Sextant Spatial Data Infrastructure for Marine Environment C. Satra Le Bris, E. Quimbert, M. Treguer Centre de Bretagne BP 70, Plouzané France

2 Sextant French marine spatial data infrastructure Objectives Collect, archive and distribute reference maps and other marine data sets Gather and make available vector and raster spatial data produced by Ifremer and its partners Web GIS providing discovery, viewing and download online services Designed according to the European INSPIRE directive for interoperability and according to the OGC and ISO TC 211 standards

3 Sextant Interoperability and Inspire Metadata normalized ISO and ISO standards compliant OGC standard Catalogue Services Web (CSW 2.0.2) Inspire directive Viewing data OGC standard - Web Map Service (WMS) Sensor Web Enablement (SWE) Data extraction OGC standard - Web Feature Service (WFS) OGC standard - Web Coverage Service (WCS)

4 Sextant a normalized portal The Editorial Page Discovery Services The Metadata Catalog View Services The Geoviewer Download Services The Basket

5 Multi thematic data holdings Environment Halieutics Water quality (coastal networks) Marine habitats Aquaculture Fishing activities Resources Economical aspects Geoscience Bathymetry Sedimentology Acoustical imagery (sonar) Ocean physics Hydrodynamics (temperature, salinity, currents) Historic data Historic photos, maps.

6 Data storage Different kind of data can be integrated: Vector (Shapefile, Oracle Spatial) Images (Scan, Orthophotos ) Grid data (Bathymetric DTM, Lidar) Models and digital analyses (multidimensional gridded datasets) Hydrodynamic Climatology (in situ, satellitales)

7 The thematic catalogs Sextant is structured in thematic catalogs: One spatial infrastructure for several catalogs and webgis They warrant: A users rights management associated to the data A restricted and secured distribution of the information And give you the choice of a website to present the associated project

8 Metadata catalog To promote the share and distribution We have normalize : Data description (ISO 19115) XML encoding (ISO 19139) Access to catalogs (CSW) Geonetwork Software At the moment: 3000 metadata on-line 5000 geographic information layers available

9 Metadata catalog You can choose many different criteria to search a metadata Where : to search a metadata according to its geospatial information What : to search a metadata according to its content Who : to search a metadata according to its producer When : to search a metadata according to its date

10 Metadata catalog six major thematic categories Human activities (Fishing, Infrastructure, Monitoring networks...) Activités humaines (Pêche, Infrastructures, Réseaux de surveillance Numerical maps Cartes scannées (Shom, IGN, Ifremer ) Imagery (Aerial photos, Acoustic images) Imagerie (Photos aériennes, Images acoustiques, ) Biological environment (Habitats, Species) Milieu biologique (Habitats, Espèces ) Physical environment (Bathymetry, Geology,..) Milieu physique (Bathymétrie, Géologie ) Regulation and management (Réglementation et gestion (Administrative boundaries, navigation data, ) (Limites administratives, Données de navigation )

14 The Geoviewer The Web GIS interface allows end-users to create maps including several layers from internal and external sources The portal access to local or remote OGC services : Displaying data by WMS The Geoviewer allows end-users : To consult and explore data Navigation, zoom tools Query layer Export map in pdf To manage layer display Layer order Transparency Symbology (grid data)

15 The Geoviewer Themes from the Catalog Legends

16 The Geoviewer Le Geoviewer Navigation tools WMS services access Layers management

17 Download Basket Choose your extraction parameters Formats Coordinate system Extraction extent Read and agree to respect the data s constraints Reception of an indicating that your extraction zip is ready to be downloaded Accessible via HTTP protocol Accessible via FTP protocol

18 Access to observation data Sensor Web Enablement (SWE) allows access to data from sensors measurement SensorML : models and schema for describing sensor metadata O&M : models and schema for encoding sensor data SOS : interface to access sensor metadata (SensorML) and sensor data (O&M)

19 Exemple : Ifremer Monitoring Network The monitoring network : access to time series

20 Exemple : Ifremer Monitoring Network From the layer table, access to the sensor metadata

21 Exemple : Ifremer Monitoring Network And then, access to the sensor data

22 Web portal - personalization Bilingualism (Ex. Charm project portal) Catalog, Geoviewer, Basket Themes names Metadata (in the same xml file)

23 Web portal - personalization Custom template for metadata Ex. Emodnet project portal

24 Web portal Custom dedicated website Ex. Emodnet project portal and DCSMM project portal (Liferay)

25 Interoperability Acces to metadata from an other website ex Extraplac project portal - (Geonetwork URL)

26 Interoperability Acces to metadata and layers from an other website Ex. Geolittoral portal and «Planification des EMR» project - (CSW and WMS protocols)
