Conclusions

Access to Spatial Data before INSPIRE (1)

First option (raster & vector) - use standardized metadata (possible since 2007)

distribution

Access to Spatial Data before INSPIRE (2)

Second option (raster & vector) - use OGC Services

  • Vector: WFS 1.0.0 (2002), WFS 1.1.0 (2006)
  • Raster: WMS 1.0.0 (2000), WMS 1.1.0 (2001), WMS 1.1.1 (2002), WMS 1.3.0 (2006), WCS 1.0.0 (2005), WCS 1.1.0 (2006), WCS 1.1.1 (2007)

Access to Spatial Data before INSPIRE (3)

Faced problems:

  • Linking data from metadata is not very flexible (only one representation is possible)
  • The Directive specifies the usage of so called download services
    distribution
  • In 2007 no generic WFS and WCS clients were available

INSPIRE Download Services (1)

Defined in the Technical Guidance Paper from June 2012

distribution

INSPIRE Download Services (2)

  • Pre-defined dataset download service

    • ATOM Implementation
    • WFS 2.0 Implementation

  • Direct-access download service

    • WFS 2.0 Implementation

INSPIRE Download Services (3)

Timetable

distribution

Solution (1)

  • Implement one consistent approach

  • Easy to provide ... and

  • easy to use

Solution (2)

  • Decision: Use INSPIRE ATOM Feeds as standard way to distribute spatial data in local and regional SDIs

Things that have to be done:

  • Implementation of a ATOM Feed Proxy for
    • WMS sources
    • WFS 1.1.0 sources
    • Download urls from ISO19139 files

  • Implementation of a webclient to support the usage of the feeds
  • Seamless integration in the central geoportal application

Conclusions (1)

  • The ATOM Feed based INSPIRE DLS proved itself in practise

  • Rhineland-Palatinate, Saarland and Hesse provide more than 6000 INSPIRE compliant DLS

  • The users are happy to have a simple and harmonized interface for accessing distributed spatial data

Conclusions (2)

  • But:The usage is negligible in comparism to the usage of the central portal itself and the usage of the WMS :-(

  • ATOM Feed Client log (actived Oct 2014)

  • distribution
