Abstract
Abstract. As in many countries, in The Netherlands governmental organisations are acquiring 3D city models to support their public tasks. However, this is still being done within individual organisation, resulting in differences in 3D city models within one country and sometimes covering the same area: i.e. differences in data structure, height references used, update cycle, data quality, use of the 3D data etc. In addition, often only large governmental organisations can afford investing in 3D city models (and the required knowledge) and not small organisations, like small municipalities. To address this problem, the Dutch Kadaster is collaborating with the 3D Geoinformation research group at TU Delft to generate and disseminate a 3D city model covering the whole of the Netherlands and to do this in a sustainable manner, i.e. with an implementation that ensures periodical updates and that aligns with the 3D city models of other governmental organisations, such as large cities. This article describes the workflow that has been developed and implemented.
Highlights
The use of 3D city models to address environmental challenges in urban areas has become common practice
Current 3D city models produced by different organisations can differ a lot because of differences in acquisition methods, differences in applications for which the 3D data is collected, differences in data structures and formats etc
The Dutch Kadaster is collaborating with the 3D Geoinformation research group at TU Delft to (1) generate and disseminate a 3D city model containing 3D topography covering the whole of the Netherlands; and (2) to do this in a sustainable manner, i.e. with an implementation that ensures periodical updates and that aligns with the 3D city models of other governmental organisations, such as cities
Summary
3D city models are not part of governmental data infrastructure solutions and still not widely used in governmental decision processes To address this problem, the Dutch Kadaster (which has the public task to provide geo-information for common use) is collaborating with the 3D Geoinformation research group at TU Delft to (1) generate and disseminate a 3D city model containing 3D topography covering the whole of the Netherlands; and (2) to do this in a sustainable manner, i.e. with an implementation that ensures periodical updates and that aligns with the 3D city models of other governmental organisations, such as cities. In this paper we describe the details of the workflow that combines several of our past researches and pilots
