Transfer of Statistical Data from the German Federal and State

Governments to the European INSPIRE Network

INSPIRE Data harmonization projects

IT.NRW


Project Summary

Project Partner

> IT.NRW (Representative for the statistics authorities of the federal states)

> con terra GmbH

Prototype

> Transformating statistics data of the federal states from the GENESIS DB into

INSPIRE Annex III (SU, PD)

Documentation of the approach

> Aggreement on how to continue with the statistics data from the federal states

Data Harmonization with Spatial ETL

Extraction of statistics data from Geodata

> Attribute information and spatial reference

> Migration into standard Applications

– Excel, Access, Oracle, MS SharePoint, Informatica 7

Migration of statistics data into SDIs

> INSPIRE (Statistical Units, Population Distribution)

> Migration into standard GIS Applications

– ArcSDE, Geodatabase, Shape Files, ...

Initial situation of INSPIRE schema mapping

INSPIRE expert knowledge and domain expertise are required

High complexity of the source data and the INSPIRE destination model

It has to be accounted for local characteristics (quality, history, contents)

- Internal data models

- Meta data

- Data history

- Data quality

- Expertise (Domain)

- INSPIRE data models

- INSPIRE specifications

- INSPIRE legislation

- INSPIRE requirements

- Expertise (Annex 1)

Challenge

Complex Source data

> IT.NRW has the semantic knowledge

> Knowledge about INSPIRE Data specifications and data structure at con

terra GmbH

Complex Targetmodel (AU, SU, PD)

> Beta Status of the tools (ISP, AfI)

> Specifications not final (Draft Version, SU, PD)


Source Data

Gemeinsamen Neuen Statistischen Informations-System (GENESIS)

Available Formats / Protocols

> SOAP Service

> XML Web-Service

> CSV-Files (preprocessed)

Conclusion

Good knowledge of source data and source schema neccessary

> Content and structure

> Complex target schema

Communication neccessary

> Close cooperation between Geo- und Statistics Department

Fuzzy use of source schemamake the mapping difficult

> Spatial ETL to harmonize the sourcedata

Schema mapping usually possible during a time frame between 5 and

10 days
