Abstract: A weather visualization system retrieves a static terrain map which is merged with dynamic weather information. The dynamic weather information may be provided from weather radar, weather satellite or remote weather observation sites. The terrain map is combined with the weather information to provide a three-dimensional weather image relative to the terrain map. The system can generate a sequence of images to provide a "fly by" animation. Path data can also be input so that a fly by of a projected storm path can be displayed. Other dynamic information can be displayed relative to the terrain map such as the locations of fires and accidents. Weather information which can be displayed includes storms, clouds, rain, snow, hail, tornadoes and severe weather. The system includes time and date information to generate appropriate shadows in the three-dimensional image.
