The INSPIRE workflow

� ANNEX I• Coordinate reference systems• Geographical grid systems• Geographical names• Administrative units• Addresses• Cadastral parcels• Transport networks• Hydrography• Protected sites

� Transformation with FUSION Data Service in two steps• Transformation of topographic data• Supplementary transformation of cadastre data

� Target coordinate reference systems• WGS84 / ETRS89 (EPSG: 4258)• UTM32 / ETRS89

� Number of features

• Topography: 0.25 million

• Cadastre data: 1.50 million

• Overall: 1.75 million

� Elapsed time of the transformation

• Topography: 0:27 h

• Cadastre: 9:53 h

• Overall: 10:20 h

Do the INSPIRE data match along the borders?

Consistent answer not possible:

� Accuracy of topography data 2-3 m

� Accuracy of cadastre data between cm and 1-2 m

� Differences in the digitalization of data(e.g. rivers, road centre lines)

� Combination of several different coordinate reference systems

�Difficult to make a general statement, but all in all:„Matching is surprisingly good“

Results and benefits

� Cross-border transformation of spatial data successful

� Data from multiple countries and source formats can be combined

� Transformation does not depend on specific formats or a

conceptual schema

� Currently available software is able to “implement INSPIRE”

� Effort for defining the transformation rules strongly depends on the

complexity of the individual schema

Project results can serve as good basis to define mapping rules

BUT: The exact definition has to be decided by the responsible persons

and experts of the respective countries

Thank you for your attention!
