BU data discoverable in the INSPIRE Geoportal
A survey on datasets available in the INSPIRE geoportal and related to the INSPIRE theme Buildings was performed in 2016.
The aim of the survey was to investigate the availability and usability of building-related datasets relevant to the Energy & Location Pilot in particular and to the needs of the EU energy efficiency policies in general.
DG ENER was also interested in evaluating the results of the survey, in order to see at what extent they could fit for support the EU Building Stock Observatory purposes.
Extending the survey to other data portals different from the INSPIRE geoportal was considered out of scope.
A methodology applied to discover in the INSPIRE geoportal building-related datasets was described and the results achieved documented in the technical report “Buildings related datasets accessible through the INSPIRE geoportal”, focusing primarily on datasets usability in a GIS environment.
For the report, a sampling mechanism to select a small number of datasets (among the several hundreds discovered in the INSPIRE geoportal) to be further inspected was adopted. Detailed information about the selected datasets inspected are available in a BU Datasets register.
It is worth to highlight that, coherently with the INSPIRE roadmap, in the INSPIRE geoportal it is possible to find BU related datasets that are not yet conformant to INSPIRE data models, and that the INSPIRE deadline of 2020 requires that Member States will have to make their Buildings datasets conformant to one of the two core profiles (Buildings2D or Buildings3D), which contain only few attributes relevant to energy policies.
Some recommendations were addressed in the report to INSPIRE implementers working in energy thematic communities, in order to better address their efforts in fulfilling on-going and future INSPIRE obligations:
- to properly extend existing INSPIRE BU data models in order to take into account the data modelling requirements coming from Energy policies, considering both existing similar activities (e.g. citygml Energy ADE initiative and GeoSmartCity project) and the rules for INSPIRE Data Specifications extension;
- to use these extended data model as target data model in as many as possible data harmonization processes related to energy efficiency of buildings, in order to improve data interoperability at EU level;
- to use the voidable properties of the INSPIRE data models only when the relevant information is actually not available;
- to carefully compile relevant metadata elements, such as lineage and resource locator, in order to document and share relevant data processing activities and therefore facilitate their reuse.
The activities carried out were useful to better understand the role of the INSPIRE buildings datasets in support of energy efficiency policies, and in particular as a source of data for the Building Stock Observatory.
Next steps would include monitoring the availability of such datasets at the level of each Member State and the analysis of their usability, in the course of INSPIRE implementation.
