ANALYSIS OF THE FUNCTIONALITY OF THE WEB APPLICATION KEPLER.GL FORVISUALIZING AND ANALYZING OF LARGE SPATIAL DATASETS
Currently, there is an active development of the multimedia direction in the cartographic display of large sets of spatial data. The tasks associated with the formation of geo-information space, the analysis of large sets of spatial data and their display by means of digital web-cartography are being solved. The goal of this article is to analyze the functionality of the Kepler.gl web application designed to visualize and analyze large sets of spatial data. At this stage of development, Kepler.gl allows you to work with data stored in one of three open text formats: CSV, JSON or GeoJSON. For practical testing of the main program functions, a map of bus and tram stops in the city of Novosibirsk was created. As a source of geodata, a shp-file was taken from the Open Street Map open set to the territory of the Siberian Federal District. Based on the results of testing some of the functionalities, it can be concluded that Kepler.gl makes it possible to significantly simplify the process of analyzing and visualizing large data sets. To a greater extent, this is provided by a graphical interface, which contains intuitive tools for choosing how to display data, filter and aggregate data, overlay information from various sources, switch between 2D and 3D modes, etc.
