Abstract:
With the development of society and economy, lightning disasters becom e more and more influential in the economic losses and society. In order to inve stigate the distribution characteristics and development law of lightning disast ers and realize the visualization analysis of lightning disasters, a visual anal ysis system for lightning disaster data, named VASLDD, was established by means of the rapid rendering method for Doppler radar figure based on user draw layer , the drawing strategy of lighting density figure and polarity figure based on d atabase, rapid merging display technology of Doppler radar data and lightning direction finder data. By means of graph, thematic map of GIS, contour map and choroplethic map etc, the system re alizes the visual analysis of lightning disasters, thunderstorms day, lightning etc. VASLDD has become a powerful tool for operational and research work.
