Horizon Systems is an open-source desktop software designed for visualization of weather radar and associated severe weather data written in C++ programming language using Qt6 framework. This software is developed by Horizon Radar Systems and licensed under GNU General Public License v3.0.[1]
The application compiles information from various government and local meteorological bodies into one radar viewer designed specifically for storm chasers and meteorology hobbyists.[2]
History
[edit]The Horizon Systems has been developed from previous prototype radar viewers such as an HTML/JavaScript single-file radar viewer and a mobile radar viewer created using the programming language Rust to a Qt6/C++ desktop application. The first known instance of Horizon Systems was "Euro Radar | The Open Source DE/FR viewer".[2]
As of version V1.1.1, the application includes support for a broad range of national radar networks across North America and Europe.[2]
