Exploitation of Hadoop framework for point cloud geographic data storage system

It has been planned that the whole region of Slovak Republic´s surface would be scanned, and there arose a need for storing the resulting data and making it publicly available. For this purpose, a scalable file-based database system for storing and accessing a large amount of geographic point cloud data was developed. The principle of the system was tested and proved to be sufficient in most situations, but under certain circumstances, single-computer solution was not satisfactory. So, the system was re-implemented using the Hadoop framework and experiments with many configurations were done. The results of the experiments are presented in this paper along with our conclusions.
