Mapbox Japan Weather Layers を使った雨雲レーダーのデモ

Mapbox Japan Weather Layers (JWL) is a popular service in Japan that provides real-time and forecasted weather information on maps, primarily using rain cloud data. The blog discusses the development of a rain cloud radar using Mapbox GLJS and JWL to visualize weather data, which is useful across various sectors such as disaster prevention, transportation, and marketing. Weather data is sourced from GRIB2 binary data files provided by the Japan Meteorological Agency (JMA), converted into tile sets, and displayed on maps through high-performance pipelines. By leveraging Mapbox's Tilequery API, users can easily access weather data in JSON format, facilitating lightweight, real-time weather visualization. The demonstration code for this service is available on GitHub, offering a practical implementation of the JWL system.
