[Termes IGN] organisme cartographique nationalRésumé : (auteur) The usage of crowdsourced geographic data and information and Volunteered Geographic Information (VGI) by National Mapping and Cadastral Agencies (NMCA) and the Geomatics Industry is a very current, challenging and topical subject. Many NMCAs in Europe are actively using these sources of spatial data within their processes and workflows in the production, management and distribution of national geographical data and associated products. One of the major obstacles in the wider adoption or even investigation of crowdsourcing in national mapping results from the lack of collaborative projects or studies between the crowdsourcing community and the NMCAs. Wider scale collaboration has not happened. This report outlines the outcomes from a workshop “Crowdsourcing in National Mapping” organised and held in Leuven, Belgium in April 2017, and funded by EuroSDR. The workshop follows on from a similar, inaugural event, held in Nottingham, UK in 2013, also co-funded by EuroSDR. The overarching goal of this workshop event in 2017 was to bring crowdsourcing projects from the spatial domain, academics/researchers, SMEs and NMCAs together for 1.5 days of debate, discussion, planning, networking and collaboration on ways to move forward in more integrated approaches to Crowdsourcing in National Mapping in Europe.
The report outlines a number of key outcomes for the stakeholders involved. EuroSDR should consider providing funding to ensure future workshops of this type take place. This will help ensure all stakeholders in this domain continue to interact, collaborate and learn from each other. In particular academic research could provide an important future role in understanding how crowdsourcing and VGI is affected by policy changes such as GDPR. The answer to how the Crowdsourcing communities and NCMAs can work together will emerge from further understanding how to define the role of NCMAs into the future. There is also still much work left to do in understanding the legal and ethical frameworks for working with VGI/Crowdsourcing from the NMCA perspective. Finally, a clear opportunity for VGI/Crowdsourcing going forward is identifying niche or new data streams to focus on.Note de contenu : Introduction

[Termes IGN] visualisationRésumé : (Auteur) The 3D cadastre concept brings data models, which are more complex than traditional 2D cadastral data models and could be followed by a large amount of data. The 3D cadastral data should be stored in database management systems, since the cadastral data integrity and consistency have to be satisfied. Relational database management system requires a tabular structure where data are stored within predefined columns and data types, and this could be uncomfortable for 3D cadastre until relational provides full 3D support. This study examines the possibility of using NoSQL databases in the 3D cadastre domain. NoSQL database stores unstructured data, which means that it is not required to define in advance what data types and categories will be used. From the 3D cadastre point of view, the NoSQL approach provides flexibility in data types and allows easier implementation of the 3D cadastral models. The implementation is conducted by using MongoDB and 3D Cadastral Data Model, where 3D cadastral data, including both alphanumerical and geometry part of data, are prepared for importing and then stored, managed, queried, and updated within NoSQL database. Furthermore, data stored in MongoDB are visualized and queried inside a web browser by using Cesium library.

[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) Using transparency as a visual variable in 3D geo-visualization offers several advantages since it can encode underlying data and at the same time relieve the occlusion. However, the usability of transparency has yet to be tested with intended users and it might vary from one application domain to another or from one task to another. This research project addresses the usability of transparency in 3D cadastre visualization, more specifically whether it helps users delimit property units (administrative boundaries) with their physical counterparts (e.g., walls) in condominium situation. In this situation, three types of boundaries (simple physical, simple administrative, and linked boundary, which is both physical and administrative) are involved in visualization, and three different transparency levels are used to represent these types. Empirical tests are administered in the form of an online questionnaire for university students in law (notarial law) and land surveying. The results show that, in general, using three different transparency levels is preferable and efficient solution to help users demarcate property units with their physical counterparts, and 63% participants correctly achieved their visual tasks with this design. Also, the transparency settings influence user’s performance. For example, applying very high transparency to simple administrative boundaries as compared to simple physical boundaries improves user certainty. Another important discovery is that many university students in notarial law are inexperienced with 3D visualization, and such inexperience affects the viewer’s certitude when carrying out visual tasks.

[Termes IGN] utilisation du solRésumé : (Auteur) The first maps and studies in the field of land use were initiated in the United States as early as before World War I. Between the two world wars such studies were carried out with the main focus on regional planning. Planning process at all levels is usually based on rich statistical materials, which allows to compare the state of the space in different time periods. In the presented paper, the authors investigated transformations of the spatial structure of lands for a part of Podgórze, the district of Krakow for the period of the past 169 years. Source materials utilised for the research works and analyses included cadastral maps from the selected analysed years, i.e. 1847, 1909, 2003 and 2016. Based on the mentioned materials, the characteristics of land parcels as spatial features were analysed and changes were determined for the periods of 1847–1909, 1909–2003 and 2003–2016 showing the present situation. Computer processing of maps was performed for this purpose, and distributions and correlations between spatial variables characterizing parcel structure were analysed for the study area.

[Termes IGN] utilisation du solRésumé : (Auteur) Historical enclosure era property-related maps can tell us a great deal about the life and times of communities in the past. This study offers a unique approach to studying the historical landscape by applying GIS techniques to the examination of an eighteenth-century English village. Using novel GIS applications relying on historical maps, the study explores various aspects of the village’s physical and social characteristics. In doing so, the study forges effective linkages between cultural and landscape variables to reveal aspects of the historical landscape in eighteenth-century Britain previously inaccessible to researchers. This, in turn, provides a much more comprehensive and sophisticated template for future use by historical geographers in a number of contexts.
