This repository contains the implementation of algorithms for hotspot computation on trajectory data. These algorithms are described in a paper by Gudmundsson et al.

J. Gudmundsson, M. van Kreveld, and F. Staals, “Algorithms for hotspot computation on trajectory data,” in Proceedings of the 21st ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems - SIGSPATIAL’13, 2013, pp. 134–143.

There are four algorithms in total, each of which places different constraints on the trajectory contained within the hotspot. Because of these variations, each case needs a different approach to find the hotspot.
