Noise in seabed terrain data, removed by the algorithm

In his PhD studies, Freek van Walderveen studied algorithms for handling large graphs that do not fit in the computer’s main memory and have to stay on slow secondary storage such as hard disks. He focused on applications in terrain data cleaning (noise removal), social network analysis, and planar graphs (such as road or river networks without bridges or tunnels).

The second topic in his dissertation is range searching data structures that can be used in (geometric) databases, for example, for efficiently reporting certain statistics for data items contained in given query ranges.

The PhD degree was completed at the Department of Computer Science, Science and Technology, Aarhus University.
