The challenges

• Source data held in non-conformant formats

• INSPIRE requires the creation of previously uncaptured data

(e.g. ‘Owner’ label)

• Cross boundary working means different coordinate reference

systems in use

• Publication of sensitive data (e.g. location of endangered

species)

• Multilingual and multicultural audience

Nature Conservation in INSPIRE

Key INSPIRE data themes:

• Protected Sites (Annex I)

• Biogeographical regions (Annex III)

• Habitats and biotopes (Annex III)

• Species Distribution (Annex III)

Data Harmonisation

• Create data translation & database mapping

• Use of ‘constants’ to include uncaptured data

• Perform coordinate transformations to single CRS

• Truncate data in line with INSPIRE specification

• Create GML 3.2.1

• Validation against INSPIRE specifications

Epsilon was one of the first NatureSDI members to publish an

INSPIRE compliant dataset

Proved that a standard off-the-shelf software tool supports the

INSPIRE requirements; no coding was involved

Data Access

Nature-SDI became one of first projects to deliver an INSPIRE

Direct Access Service using WFS 2.0

Partners of Nature-SDI project achieved outcomes and benefits

in excess of original requirements.

• Deliver GML as required by INSPIRE

• Publish to GML 3.2.1 (INSPIRE Data Specification)

• Deploy Direct Access Service in short timeframe for data access

• Create WFS 2.0 without coding

• Publish KML files and serve through consumer mapping apps

such as Google Earth

A successful experience

• as a practitioner who:

– initially remapped one Natura2000 national dataset (1 shp + 1 Access RDBMS downloaded from

EIONET) from the Standard Data Form of EEA to the PS-natura2000 INSPIRE gml application

schema (all gml elements mandatory!)

– then remapped again to the INSPIRE PS-full xsd (after that PS-natura2000 was deprecated with

version 3.1 of DS)

– in both cases successfully validated the harmonised datasets, both against the INSPIRE target

schemas and the relevant schematron rules

– in both cases managed to deploy a WFS 2.0 with very few clicks

Two main reasons for a successful experience in harmonising spatial datasets

according to the INSPIRE gml application schemas:

• as the coordinator of the DH-TWG (Data Harmonisation Technical Working Group) inside the

EU project NATURE-SDIplus who:

– coordinated the harmonisation of 234 spatial datasets belonging to 4 INSPIRE data themes (PS, BR,

HB, SD), assisting 20 different Data Providers from 17 different EU Member States, which used 14

different harmonisation “tool-configurations”

Conclusions

Data Harmonisation

• Data translation & database mapping

• ‘Constants’ to create uncaptured data

• Perform coordinate transformations to single CRS

• Truncate data in line with INSPIRE specification

• Validation against INSPIRE specification

Data Publication

• Deliver GML as required by INSPIRE

• Publish to GML 3.2.1 (INSPIRE Data Specification)

• Deploy WFS 2.0 in days

• Publish KML files and serve through consumer mapping apps such as

Google Earth
