  2. 2. www.r3-gis.com2Outline•The Open Geospatial Consortium•The most relevant OGC specifications•OpenLS•INSPIRE•The Transport Network specification•FreeGISGeo-spatial standards and transports: OGC and INSPIRE
  3. 3. www.r3-gis.com3The Open Geospatial ConsortiumWhat is the OGC?The OGC is an consortium of more then 400members, among those are• Companies• Government agencies• UniversitiesGeo-spatial standards and transports: OGC and INSPIRE
  4. 4. www.r3-gis.com4The Open Geospatial ConsortiumWhat are the OGC standards about?“OGC® Standards support interoperablesolutions that "geo-enable" the Web, wirelessand location-based services andmainstream IT.”Geo-spatial standards and transports: OGC and INSPIRE

  6. 6. www.r3-gis.com6The Open Geospatial ConsortiumIn other words, how to handle geographicalinformation in• Data (Raster. Vector, Attributes)• Metadata (authorship, licence, accuracy)• Services (how to get the above)Geo-spatial standards and transports: OGC and INSPIRE
  7. 7. www.r3-gis.com7Data formatsRaster data (grid)satellite imagesdigital aerial photosdigital elevation dataDefault format is GeoTIFFGeo-spatial standards and transports: OGC and INSPIRE
  8. 8. www.r3-gis.com8Vector DataMore complicated then rasterA common geometry model must be defined,which must be simple enough to allow awide range of computations and must beeasy to implementA common geometry model is defined in theSimple Feature SpecificationThis is the basic specification for vector dataGeo-spatial standards and transports: OGC and INSPIRE
  9. 9. www.r3-gis.com9Vector Data: Simple FeaturesBasically, 2D entities are handled, ATMGeometries are based on linear interpolationsGeometries must respect some topologicalrules in order to be validGeo-spatial standards and transports: OGC and INSPIRE

  14. 14. www.r3-gis.com14GMLThere are many encodings of the geometries.Encodings are available for text and binaryrepresentations.GML is an XML based encoding of thegeometry (and a lot more)Geo-spatial standards and transports: OGC and INSPIRE
  15. 15. www.r3-gis.com15MetadataTypical metadata are• Title• Abstract• Spatial Reference System• Keywords• Authorship• Licences• Spatial position (envelope)• Metadata is important for cataloging andsearchingGeo-spatial standards and transports: OGC and INSPIRE
  16. 16. www.r3-gis.com16OGC ServicesThe OGC Services are all web basedTypically, OGC servives are self describing(Capability document)Preferred exchange formats are XML based(except for raster data)They allow to deliver metadata for the serviceGeo-spatial standards and transports: OGC and INSPIRE

  35. 35. www.r3-gis.com35INSPIRE and OGCINSPIRE defines a precise structure for the databelonging to a wide range of topics relatedto enviroment, government and transport:Annex I: Administrative Units, CadastralParcels, Geographical Names,Hydrography, Protected Sites, TransportNetworks, AddressesAnnex II & III add 24 topicsGeo-spatial standards and transports: OGC and INSPIRE
  36. 36. www.r3-gis.com36INSPIRE: Transport NetworksThis specification defines how data setsbelonging to road, rail, air and watertransport networks and related infrastructureshall be structured in order to allow aseamless integration between differant datasets different data providers.Geo-spatial standards and transports: OGC and INSPIRE

  38. 38. www.r3-gis.com38The software sideThere is a large choice of software to createOGC and INSPIRE compiant services, atleast for WMS (maps), WFS (vectors andattributes), WCS (raster data) and CSW(cataloging and searching)Example FreeGIS.net*• * FreeGIS.net is an Interreg Italy-Switzerland project financed by theProgram of superregional cooperation Italy-Switzerland 2007-2012 ofthe ERDF and the European Union. Partners are the Free SoftwareCenter South Tyrol, R3 GIS, Office of information technology cantonof Graubünden, Office 9.6, Province of Bolzano and Sourcepole AGGeo-spatial standards and transports: OGC and INSPIRE
  39. 39. www.r3-gis.com39FreeGIS.netFrom a software POV, FreeGIS has the goal toallow a integrated solution to import, storeand publish geographical data compatiblewith OGC and INSPIRE.The software created within the FreeGIS.netproject is Open Source SoftwareGeo-spatial standards and transports: OGC and INSPIRE
