Porovnání rychlosti zpracování vybraných vektorových formátů v prostředí OpenLayers

Abstract

Subject of this thesis is to compare the processing speed of selected vector formats (GML, KML, GeoJSON) intended for visualization of spatial data. Open-source environment OpenLayers is used for implementation of this solution. Sets with the specified number of spatial objects are modified using QGIS and then converted into the required formats. Measuring of speed processing is carried out by modifying the OpenLayers library and events used by the library offers. This application is located at Apache web server and allows testing of formats. The results of this work would help the development of projects such as GIS and with selecting the most appropriate vector formats according to given criteria.
