Performance enhancing of storage system for point cloud geographic data

This paper deals with the problem of storing and distribution of geographic point cloud data. A scalable file based database system for storing and accessing a large amount of point cloud geographic data was developed. The principle of the system is briefly described and the results of experiments with different file formats and their impact on the overall performance of the system as well as to space occupied on hard disk drives are presented. Based on results, one format was chosen for a data layer of the system. This paper also offers results of tests focused on scaling the main data structure and its optimal setting under certain circumstances.
