Aligning heterogenous topographical data to derive multiscale content for the Dutch nationwide Spatial Data Infrastructure

The Dutch Kadaster is responsible for the acquisition and maintenance of topographical data and visualisations at scale 1:10k and smaller. This is currently realised through an acquisition process by topographers who acquire 1:10k data from aerial images. In a next step, the smaller scale data and visualisations are derived by a fully automated generalisation process. Now a countrywide large-scale topographical dataset has become available, i.e. the key register large-scale topography (BGT), we have started a project to explore how to derive the Kadaster data from the BGT. This has two main objectives: to save money (i.e. collect once and use data many times) and to make the Kadaster data consistent with the BGT data. In this extended abstract we describe the project in which we define the content of the next generation Kadaster products that will be derived from BGT data.
