INSPIRE Conference, 25 June 2010, Krakow, Poland 3

Laboratory for Research and Development (R&D) for both Geo and Land registry boards at Kadaster:

  • Translating innovative ideas into real world applications
  • Practising standards such as INSPIRE
  • Participating in research projects e.g. ESDIN
  • Developing various demo-applications for Kadaster business
  • Using both Open and Closed Source software / environments

ESDIN WP 11 – Best Practice for Content Transformation

  • Download service via WFS
  • View services via WMS

Two INSPIRE Annex I Themes:

  • Cadastral Parcels (CP)
  • Addresses (AD)

Transform Dutch national geodata sets:

  • Buildings and Addresses (BAG)
  • Cadastral parcels (BRK)

Transformation

A process through which a data / coordinate model can be changed conform to another data / coordinate model in order to get harmonized datasets.

INSPIRE Conference, 25 June 2010, Krakow, Poland 7

INSPIRE Approaches:

  • Offline transformation of the spatial data and provision of

the transformed data in the View and Download service.

  • On-the-fly transformation of the spatial data during

request processing in the View and Download service.

  • Transformation through a separate Transformation

Service e.g. through WPS (Web Processing Service).

INSPIRE Conference, 25 June 2010, Krakow, Poland 8

ESDIN Approaches:

  • Off-line Transformation: the transformation is realized through an

entirely off-line pre-processing approach using a copy of a data set from the original database through a service database.

  • On-the-fly Transformation: the transformation is arranged

through an online process during the interactive request- response communication through web services.

  • Combined Transformation: the transformation is applied using a

combination of the two earlier introduced methods. Firstly, data from the original database is transformed and stored in a service database.

+ Single integrated DB data model + Software architecture: divide and conquer + Reuse: NMCA’s only need step 1 (offline) + Performance: minimal on-the-fly processing + Cross-theme relationships + FOSS works for INSPIRE!! + Not just free (as in free beer) + Mix and match FOSS components + Community support + Integration is the key + Joint development for NMCA’s

  • Data synchronization with source data

Conclusions

Improve Database Model – optional attributes – additional Annex I-III data themes + ESDIN ExM – cross-theme relationships On-the-fly transformation with GeoServer2 Collaboration with NMCA’s and Open Source providers – share experience – share codebase http://code.google.com/p/inspire-foss
