On September 4 2017, the Knowledge Centre Open Data organised the well attended workshop ‘Towards a Map of Open SDI/INSPIRE’ at the INSPIRE 2017 Conference in Kehl (Germany) and Strasbourg (France). In this workshop, several experts presented their view and experiences on Open SDI and a first prototype of the ‘Map of Open SDI in Europe’ was shown.

The ‘Map of Open SDI in Europe’ explores the openness of NSDI/INSPIRE implementation in Europe, covering three key dimensions of Open SDIs: the readiness, the data availability and accessibility, and the impact of open SDIs. In the discussion sessions on the different dimensions of Open SDIs new ideas and suggestions were provided that will be incorporated in guidelines on how to measure and assess the open SDI.

The ‘Map of Open SDI in Europe’, a project of the Knowledge Centre Open Data of Delft University of Technology, is developed to provide SDI decision makers, practitioners and researchers with a more comprehensive understanding of the openness of spatial data infrastructures in Europe. The Map covers three key dimensions of Open SDIs: readiness, implementation and impact. The map provides an overview of the status of Open SDIs in different European countries.

The EuroSDR workshop on Sustainable Open Data Business Models for NMCAs will be organized in Delft (the Netherlands) on 18 and 19 September 2017. The workshop will bring together the NMCAs to present and share their experiences of open data and discuss the research results with representatives of academia.

Issues that will discussed will be:

• What were the outcomes of the online survey of April 2017?
• Which funding models can be utilised by NMCAs and how sustainable are these?
• What have the effects of open data been on the operational costs of the NMCA?
• Which options do NMCAs have to their disposal to refinance their operational costs?
• Is the supply of open data living up to expectations?
• What are the non-financial challenges to implementing open data?
• Is there a future for a pan-European open data infrastructure?

When: 18 – 19 September 2017

On June 30 PhD candidates of the Katholieke Universiteit Leuven and Delft University of Technology exchanged their PhD research concepts and ideas with each other in Leuven. Joep Crompvoets welcomed the Delft guest and introduced KU Leuven and the Public Governance Institute and Bastiaan van Loenen introduced the Knowledge Center Open Data. The PhD candidates that presented their research were:

• Maxim Chantillon: The Development of Public Policy Governance Models for Geospatial E-services, Characterized by a Focus on Public Sector Values
• Agung Indrajit: 4D Open SDI for Urban Participatory Spatial Planning Monitoring
• Stijn Wouters: The governance of e-government projects in Flanders
• Bujar Nushi: Assessing SDIs through stress testing
• Ine Buntinx: Governance mechanisms to support the use of innovative geospatial technologies for land tenure recording: case studies in East-Africa
• Frederika Welle Donker: Sustainable open data business models
• Roel Heijlen: (Big) data governance in the public sector

Next meeting wil be organised in the Summer of 2018 in Delft.

KCOD researcher Hendrik Ploeger is co-author of an article in ISPRS International Journal of Geo-Information __ on the registration of multi-level property rights in 3D in the Netherlands. The article reports on the first 3D cadastral registration in The Netherlands, accomplished in March 2016. The solution was sought within the current cadastral, organisational, and technical frameworks to obtain a deeper knowledge on the optimal way of implementing 3D registration, while avoiding discussions between experts from different domains. The article presents the developed methodology to represent legal volumes in an interactive 3D visualisation that can be registered in the land registers. The source data is the 3D Building Information Model (BIM). The methodology is applied to two cases: (1) the case of the railway station in Delft, resulting in the actual 3D registration in 2016; and (2) a building complex in Amsterdam, improving the Delft-case and providing the possibility to describe a general workflow from design data to a legal document. An evaluation provides insights for an improved cadastral registration of multi-level property rights. The main conclusion of the article is that in specific situations, a 3D approach has important advantages for cadastral registration over a 2D approach. Further study is needed to implement the solution in a standardised and uniform way, from registration to querying and updating in the future, and to develop a formal registration process accordingly.
