BAG & BGT: Spatial Key Registers - Compatibility and Municipal Use in Zwolle
MetadataShow full item record
This thesis seeks to explore the impacts of the introduction of two key registers on the spatial data administration of the municipality of Zwolle. These key registers will authentically store building and address data (BAG) and large-scale topographic data (BGT). Using mainly policy documents and interviews, the degree of compatibility between the BAG and BGT key registers is examined, as well as several possibilities for altering the spatial data administration of municipalities, and Zwolle in particular. The analysis of the degree of compatibility between the BAG and BGT key registers focuses on the building geometry that is present in both registers in a different form. While this double presence is contrary to the goals of the network of key registers, and the NUP e-government program it belongs to, it is in practice not a major problem for the implementation of BAG and BGT, since numerous organizational and technical options exist that can be used by municipalities to mitigate the problems. The introduction of the BAG and BGT key registers also provides an opportunity to evaluate the municipal spatial data administration at Zwolle. Potential changes could include the integration of municipal BOR and BGT data, data collection methods, centralization of municipal data collection and maintenance, and the division of BGT sourceholder data.
