Map Construction Algorithms,geo-referenced tracking data, there has been a recent surge in map construction algorithms coming from different computer science domains.This chapter gives a comprehensive overview and comparison of the various algorithms by identifying and focusing on three emerging categories of map construction

,Fréchet Distance-Based Map Construction Algorithm,raph. The Fréchet distance is used as part of the map-matching algorithm and to provide quality guarantees for the constructed map. One of the contributions of this work is to separate edge regions from vertex regions when providing quality guarantees, and to specify the extent of these regions. The

Density-Based Map Construction Pipeline, data density function is computed and an undirected skeleton graph is constructed using grayscale skeletonization of the density. In several different steps the pipeline then uses the trajectory data to refine the topology and the geometry of the graph using the continuous information represented i
