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.

The KCOD contributed to the 17th European Conference on Digital Government ECDG 2017 from 12-13 June 2017. Bastiaan van Loenen presented the paper entitled “Log File Analytics for Gaining Insight into Actual Use of Open Data” based on the research of Wouter Labots. Following open data policies worldwide, an increasing number of public organisations has now published open data that is free to be used by anyone. However, despite the significant increase in use of this open data, the open data providers are mostly not aware of their users and the way in which the data is actually re-used. We explored the use of log files of the actual use of open data to identify the users and to explore how the open data is being used. By means of a case study in which we apply log file analytics to the Dutch open geographical data portal we show that this approach is promising for analysing open data use. This approach will yield many new insights for open data providers to improve and fine-tune their open data offer and policy makers will be provided with data on actual use to evaluate their open data policies. Our analysis shows that citizens are a much heavier user of open data than currently assumed: citizens as major users of open government data should be taken much more seriously in the demand driven open data policies. We recommend transferring the pilot project into a permanent monitoring instrument for open data use and exploring additional analytics for using the rich data that log files provide for.

KCOD researcher and PhD candidate Agung Indrajit presented his short paper on ‘Multi-Domain Master Spatial Data Management for Open SII in Indonesian Smart Cities’ at the AGILE 2017 Conference. AGILE 2017, the annual international conference on Geographic Information Science organized the Association of European Geo-Information Laboraties (AGILE), was held from 9 -12 May in Wageningen, the Netherlands. This year’s conference theme was Societal Geo-Innovation, and several topics were covered: Big Spatial Data, Analysis and Visualization, Volunteered Geographic Information and Community Observatories, Socio-Economic Impact Assessment of GI and GIScience, and Technology Education and Training. Agung presented some of the first results of his PhD research as part of the conference track on ‘Spatial Temporal Analysis’.
