ArcGIS is the de facto standard of geo information systems (GIS). Thanks to WMS and WFS capability, arbitrary data layers can be easily integrated into your personal ArcGIS application. For instance, the following example shows real-time radar images, satellite images, and lightning data with the power line network of a major transmission system operator. A time slider allows operators to see past and short-term forecasted data, which enables them to estimate the impacts of severe storms to their infrastructure. As well as the aforementioned variables like radar, satellite, and lightning data, the weather API provides short-term forecasts (nowcasts) in 5-minutes resolution.
