Nowdays, large volumes of spatio-temporal data and trajectories are generated.
These data describe phenomena and patterns that may be identified through analysis
techniques. One of these is the Hot Spot analysis where it aims to find statistically
significant clusters of such phenomena. The main area of application of this analysis
is spatial data.
The purpose of this diploma thesis is to describe the problem of Hot Spot analysis on
large-scale spatio-temporal data and trajectory data and to propose solutions to the
above problems through parallel processing algorithms for big data.
