Abstract

The invention discloses a GIS (Geographic Information System) platform processing method for mass lightning data, which comprises the following steps of: (1) establishing a lightning database to provide a basic data source for lightning analysis through inducing historical data and acquiring data in combination with a real-time lightning detection system, wherein lightning information is intuitively displayed by using a GIS platform for the convenience of predicting the development tendency of lightning; and (2) analyzing lightning data through an interactive method, and finally forming a weather product which can be issued, wherein the lightning data comprises the query and statistics of customized lightning information, lightning space density analysis and the like. As mass lightning data is processed on the GIS platform, the demand on lightning protection services is met. Real-time or delayed load, customized display as well as time domain and spatial analysis can be performed on a lot of lightning data, and therefore a technical support is provided for weather forecasters to observe and analyze lightning for the convenience of lightning prevention forecast in a better manner.

Description

technical field [0001] The invention belongs to the intersection field of lightning protection technology in GIS and meteorological information technology. Geographic Information System (GIS) is a spatial management system for the storage, display and related analysis of spatial information; it can conveniently split and store spatial data in the form of various attribute data, and display them in an intuitive and friendly way. Then perform various required spatial analysis, such as buffer analysis, etc.; in addition, it also supports various attribute queries and spatial relationship operations between graphics. Background technique [0002] The occurrence of lightning in nature is highly random, instantaneous and dangerous, and it is closely related to the strong convective system of the atmosphere. The lightning monitoring network is mainly composed of the ground atmospheric electric field monitoring network, lightning location monitoring network, and ground automatic ob...
