- 2. www.deegree.org lat/lon Who we are: ● ● ● ● since 2000 software development and consulting in Germany linking standards-based geospatial applications with professional open source technology From startup active member of the Open Geospatial Consortium (OGC), since 2010 Principal Member Active participation in enhancing the capabilities of FOSS4G software, especially within the deegree initiative www.lat-lon.de
- 3. www.deegree.org Agenda ● Overview on deegree ● From local data to INSPIRE services ● Outlook www.lat-lon.de
- 4. www.deegree.org deegree initiative ● ● Provides state-of-the-art geospatial software implements standards-based software for sustainable and interoperable solutions ● LGPL licence ● Since 2010 incubated OSGeo project EXSE 2000 deegree 2 2002 deegree 1 www.lat-lon.de 2005 OSGeo 2008 2010 deegree 3
- 5. www.deegree.org deegree & OGC Reference Implementations A fully functional, licensed copy of a Tested, branded software that has passes the test for an associated conformance class in a version of an Implementation (OGC Compliance Testing Program: Policies & Procedures) www.lat-lon.de
- 6. www.deegree.org More Standards... ● Implementing: – Web Processing Service 1.0.0 – Catalogue Service 2.0.2 (ISO AP, ebRIM) – GML 2 – 3.2.1 – Filter Encoding 1.1.0 & 2.0.0 – SLD 1.1.0 – SE 1.1.0 www.lat-lon.de
- 8. www.deegree.org Challenges Harmonizing local datasets to complex INSPIRE data themes – Transformation between different data models – Encoding: GML 3.2.1 www.lat-lon.de
- 9. www.deegree.org Challenges Providing Geospatial Web Services compliant to INSPIRE profiles (technical guidance) for: – Discovery Service (CSW 2.0.2 ISO AP +) – View Service (OGC WMS 1.3.0 +) – Download Service (OGC WFS 2.0.0 +) www.lat-lon.de
- 10. www.deegree.org Harmonizing local data into complex INSPIRE datasets www.lat-lon.de
- 12. www.deegree.org What is the best choice for data harmonization? ● Manual transformation? ● XSLT Scripts? ● Transformation within a database? ● Using ETL tools? HALE www.lat-lon.de
- 13. www.deegree.org The answer: There is no best choice www.lat-lon.de
- 14. www.deegree.org Why is there no best choice? ● ● ● ● Every dataset has specific requirements Some methods have shortcomings, some are too complex Methods do not fit with established workflows Preferences of the people who have to do the data harmonization www.lat-lon.de
- 15. www.deegree.org The Goal: Valid INSPIRE GML National Data www.lat-lon.de Extract Transform Load Valid INSPIRE GML deegree 3
- 17. www.deegree.org Web Processing Service ● OGC Specification ● Provides 3 Operations: – GetCapabilities – DescribeProcess – Execute www.lat-lon.de
- 18. www.deegree.org Standard-based interface for Schema Transformation deegree WPS Processlet: DB Triggers Processlet: FME Workbench www.lat-lon.de Processlet: XSLT Script
- 20. www.deegree.org Advantages of this Approach ● Use the Transformation Method of your choice ● Use more than one Method ● OGC interface between harmonization and publication www.lat-lon.de
- 21. www.deegree.org Now we have harmonized INSPIRE data www.lat-lon.de
- 23. www.deegree.org You remember that challenge? Providing Geospatial Web Services compliant to INSPIRE profiles (technical guidance) for: – Discovery Service (CSW 2.0.2 ISO AP +) – View Service (OGC WMS 1.3.0+, OGC WMTS 1.0.0+) – Download Service (OGC WFS 2.0.0 +, Atom Feeds) www.lat-lon.de
