Visualization and analysis of WWLLN network data on the territory of the Altai-Sayan region using Web-GIS
Abstract.At present, the technology of creating information and analytical systems in the field of climate-ecological monitoring has been developed quite well. The construction of such systems is based on the use of GIS and Internet technologies and includes both data from monitoring stations and remote sensing data. The article describes the architecture of a web application that implements elements of GIS technologies and is developed to solve the tasks of collecting, storing, visualizing, searching and analyzing information on lightning discharges recorded by the World Wide Lightning Location Network (WWLLN). The software and technology platform of the system is based on the use of freely distributed technologies and software, including the Ubuntu operating system, the NGINX web server, Python as the main development language and the Django framework, the PostgreSQL / PostGIS database, the GDAL libraries, the OpenLayers. The WWWLNN archive data and the results of clustering are included in the web-GIS database. The system provides the feature of selecting information about lightning discharges, as well as performing cluster analysis for the sample obtained. The developed web-based GIS can provide specialists with convenient web-based tools for using WWLLN data to study regional climatology of lightning activity.
