Supporting INSPIRE implementation: the Thematic Clusters for topographic and cadastral reference data
Thursday, 28 May 2015, 1330 – 1500 hrs
WORKSHOP DESCRIPTION
The workshop will introduce the new initiative of the INSPIRE Thematic Clusters Collaboration Platform, developed to support INSPIRE implementation in the Members States. The aim of this platform is to help the sharing of experiences and best practices regarding INSPIRE. It is meant to be the place to ask questions and resolve implementation issues. The 34 INSPIRE data themes have been grouped into 9 Clusters comprising themes that are closely related.
This workshop will be focused to describe the Clusters concerned to data in the scope of Mapping and Cadastral Agencies (topographic and cadastral reference data) at all levels of administration. The main goal will be to present and describe an initial list of detected, relevant implementation issues in this scope, to promote discussion with the audience (implementers, users, technical experts) and get feedback and results on these topics.
Specific learning objectives -
Attendees will have the opportunity to:
- Expose their implementation issues related to INSPIRE;
- Share their experience on this area;
- Compare different approaches and solutions;
- Contrast their needs with such solutions to let further improvement;
- Learn from the others participation.
Attendees will be encouraged to contribute with their knowledge not only during the workshop, but also with their subsequent participation into the collaboration platform.
All this knowledge transfer will constitute a significant input for the activity of the INSPIRE Thematic Clusters which will be finally contributing to the Maintenance and Implementation Framework (MIF).
TARGET AUDIENCE
The workshop is targeted to:
- Any data producer of INSPIRE themes:
- Thematic Cluster #6:
Hydrography, Geographical names, Administrative units, Cadastral parcels, Addresses, Buildings, Transport networks.
- Thematic Cluster #3:
Elevation, Orthoimagery, Coordinate reference systems, Geographical grid systems.
National or Regional Mapping and Cadastral Agencies are often significant data providers for these themes and therefore within the target audience. - Any existing or potential user of data from the INSPIRE themes above.
- European Commission.
- Any interested person.
- Public sector professionals responsible for INSPIRE implementation in the scope of mapping and cadastral agencies data.
- Other public or private sector professionals with a role or interested in the INSPIRE implementation regarding such kind of data.
- Users of mapping and cadastral agencies data to cover specific applications;
WORKSHOP REQUIREMENTS
Instructions for participants:
- A laptop is not required for attendees, but it can be useful in case they are interested to search related documentation on-the-fly.
- Pre-workshop preparation:
It would be desirable that attendees think in advance about relevant implementation issues, use cases and needs in the scope of mapping agencies data.
In particular, they are encouraged to explore the contents of the INSPIRE Thematic Clusters collaboration platform in the scope of Topographic and Cadastral Reference Data:
Thematic Cluster #3 - Elevation, Orthoimagery, Reference systems and Geographical grids group
Thematic Cluster #6 - Topographic and Cadastral Reference Data group
They are welcome to participate in the on-line discussions by joining these two groups and also to their corresponding sub-groups.
DETAILED WORKSHOP AGENDA
- Introduction: The INSPIRE Thematic Clusters Collaboration Platform –
Presenter: Jordi Escriu (ICGC / Facilitator Cluster #3). - State-of-play of Reference Data Thematic Clusters –
- Cluster #6: Hydrography, Geographical names, Administrative units,
Cadastral parcels, Addresses, Buildings, Transport networks themes.
Presenter: Anja Hopfstock (BKG / Facilitator Cluster #6).
- Cluster #3: Elevation, Orthoimagery, Coordinate reference systems, Geographical grids themes.
Presenter: Jordi Escriu (ICGC / Facilitator Cluster #3). -
INSPIRE implementation topics.
Vector data implementation topics
- Flattening of data models.
INSPIRE data models have a hierarchic structure that is not easily accepted by most of existing tools (e.g. GIS, ELF geo-tools). The flattening of INSPIRE data models may be a solution.
Presenter: Dominique Laurent (IGN-F / Chair of EuroGeographics INSPIRE KEN).
- How to make and deliver extensions of INSPIRE data models.
New products are now often designed based on INSPIRE data models. The ideal solution would be to have an extended INSPIRE model that may be used to deliver data both at national level and European level. However, making correct extensions of INSPIRE models raises issues (non-extensible code lists, validation…).
Presenter: Dominique Laurent (IGN-F / Chair of EuroGeographics INSPIRE KEN).
Raster data implementation topics
- Encoding of coverages.
Most raster information (e.g. Elevation and Orthoimagery data) shall be provided for INSPIRE by Member States using the concept of coverage from ISO 19123. At implementation level, this means data shall be encoded in GML (several options available: multipart representation, external file encoding, inline encoding).
Member States data is commonly implemented using well-known image file formats (TIFF/GeoTIFF), so that encoding of coverages is therefore one of the issues to be tackled by data providers.
Presenters: Julián Delgado (IGN Spain) & Sören Dupke (conterra)
- WCS services.
Use of ATOM feed is at the moment the only possibility to publish a raster data download service in the INSPIRE scope.
MIG-T is currently drafting a proposal to open a MIG temporary sub-group on WCS (MIWP-07b) to explore the possibility of using WCS services as an INSPIRE download service option.
This presentation is targeted to catch ideas from the audience that could serve as input for MIWP-07b (experiences when using WCS, benefits and drawbacks, use cases).
Presenters: Jordi Escriu (ICGC / Facilitator Cluster #3).
Additional implementation topics (if time permits)
- Management of persistent identifiers and temporal aspects.
- Handling of big features.
Presenter: Dominique Laurent (IGN-F / Chair of EuroGeographics INSPIRE KEN).
- Wrap-up & Conclusion.
Presenter: Jordi Escriu (ICGC / Facilitator Cluster #3).
