The Netherlands has recently launched a 3D map covering the whole country, in which all buildings, roads, trees, canals are 3D geometries. It was created by adding the third dimension, obtained from airborne laser-scanners, to the objects in the 2D topographic map. This leads to a massive amount of information: 15M+ objects, billions of elevation points, and triangles.
The aim of the project is to investigate and develop methods to efficiently store and maintain the dataset in a database, and to disseminate it to practitioners. The existing database solutions for managing 3D volumetric objects will be tested with massive datasets and improved if necessary. The biggest challenge is the management of massive TINs (triangulated irregular networks) in a database. The PhD student will have to design and develop new data structures, implement them, and compare different alternatives. A prototype download service that generates 3D datasets tailored to specific applications will also be explored.
The project will take place in the 3D geoinformation group under the supervision of Prof. Jantien Stoter and Dr. Hugo Ledoux. It is fully funded by the Dutch Technology Foundation, and it is part of a large project in which three universities and 11 organisations are involved. We expect the PhD to collaborate with the researchers and practitioners involved in the project.
