1 Processing and serving INSPIRE data with deegree Sebastian Goerke

2 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

3 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 deegree 2 OSGeo deegree 1 deegree 3

4 deegree & the OGC OGC Reference Implementations (currently recertification in progress) Web Coverage Service Web Map Service Web Map Service Web Feature Service Web Feature Service Web Map Tiling Service Geography Markup Language SLD Feature Portrayal Service 1.1.0

5 More Standards... Implementing: Web Processing Service Catalogue Service (ISO AP, ebrim) GML Filter Encoding & SLD SE 1.1.0

6 What about INSPIRE???

7 How INSPIRE works

8 Challenges Providing Geospatial Web Services compliant to INSPIRE profiles (technical guidance) for: Discovery Service (CSW ISO AP +) View Service (OGC WMS ) Download Service (OGC WFS ) Encoding: GML Harmonizing local datasets to complex INSPIRE data themes

9 Providing INSPIRE compliant webservices with deegree

10 How deegree does INSPIRE National Data Extract Transform Load Valid INSPIRE GML deegree 3

11 In detail deegree 3 WMS INSPIRE View Service INSPIRE Download Service WFS WFS-T INSPIRE Data Sets INSPIRE Feature Store Loader PostGIS Oracle SQL Server

12 deegree webservices & INSPIRE Implementing: Download Service Pre-defined Dataset Download Service Direct Access Download Service View Service WMS Profile WMTS Profile Discovery Service Complex INSPIRE GML Data Themes

13 deegree 3 downloadservice feature highlights Support of INSPIRE Download Service Specification WFS / 1.1.0, WFS-T + XLink profiles GML 2 / 3.0 / 3.1 / 3.2 output / input ISO 19107: Supports complex geometries Full XPath 1.0 support in filters On-the-fly coordinate transformation Streaming architecture High scalability

14 deegree 3 viewservice feature highlights Support of INSPIRE View Service Specification WMS / Rendering of complex datasets Sophisticated styling using SLD or SE GetFeatureInfo Streaming High scalability

15 deegree 3 viewservice feature highlights Support of INSPIRE View Service Specification WMTS Cascading WMS and WMTS GetFeatureInfo Support Real Caching High scalability

16 deegree 3 discoveryservice feature highlights Support of INSPIRE Discovery Service Specification CSW (ISO AP 1.0.0) Fully transactional Pluggable 'metadata stores' allow to add support for new APs and backends Modular inspector architecture allows to validate records Count interface for occurences of metadata elements

21 Really?!

22 No!

23 National Data Extract Transform Load Valid INSPIRE GML deegree 3

24 deegree 3 WMS INSPIRE View Service INSPIRE Download Service WFS WFS-T INSPIRE Data Sets INSPIRE Feature Store Loader PostGIS Oracle SQL Server Do we really want to do this manually?

25 How to do it automatically? How to support more than one ETL tool?

26 Web Processing Service

27 Standard-based interface for ETL Tools deegree WPS ETL Tools (Valid INSPIRE GML) deegree INSPIRE Services

28 Advantages Use the ETL Tool of your choice Use more than one ETL tool OGC interface between harmonization and publication Choose between several Database Backends (Oracle, Postgres/PostGIS, MS SQL Server, Ingres) Independence from database and ETL developer deegree is OGC reference implementation for nearly all INSPIRE service profiles : WFS WMS WMTS GML 3.2.1

29 Some examples

30 Gazetteer for the province of Bolzano (IT) Gazetteer Service based on INSPIRE compliant deegree download service providing INSPIRE Annex I data theme Addresses

31 View & Download Service for Hamburg INSPIRE compliant View and Download Services based on deegree providing INSPIRE Data Theme Protected Sites This means: Direct Access Download Service INSPIRE WMS profile Having INSPIRE compliant Protected Sites data

32 EU INSPIRE Geoportal INSPIRE compliant Discovery Service providing metadata from all member states INSPIRE compliant View Service (WMTS) providing harvested member state's view services Harvester which collects member states metadata and network services data Registry to manage those data Validator to ensure compliance of metadata to INSPIRE requirements

33

34 EU INSPRIE Geoportal

35 Outlook What's hot? Providing INSPIRE Annex III datasets with deegree INSPIRE Metadata Validator deegree sercurity proxy Upcoming deegree 3.4

36 Thank you for your attention! Sebastian Goerke
