Embodiment Construction

[0045] Such as Figure 8 As shown, in order to solve the data monitoring, storage and display problems of lightning, the present invention mainly includes four modules in combination with the actual situation of lightning data processing: server data monitoring module, client configuration module, GIS operation function module, lightning location display , Lightning data query module, etc.

[0046] ①Server data monitoring module

[0047] The main purpose is to collect data from the lightning location monitoring network to the local server monitoring station, update the local data through real-time monitoring algorithms, and import the original data into the lightning data GIS database through the method of noise reduction and preprocessing to form a lightning data resource layer. Realize operations such as inserting, deleting, and modifying the Lightning data database, and the data service interface communicates with the client through the use of XML message processing to enabl...

Abstract

The invention discloses a mass lightning data space-time analysis method based on a geographical information system (GIS). The method comprises the following steps of: 1, constructing and maintaining a lightning space database by combining a GIS technology and researching a data quality control method for a lightning information source, and establishing a lightning real-time positioning and monitoring system for acquiring an information source of lightning generation; and displaying a positioning distribution of lightning in real time in the form of a space element and forecasting the latest tendency of the lightning; 2, counting and analyzing the historic lightning data by an interaction method, namely methods for analyzing spaces of any shapes, analyzing the lightning density, analyzing a thematic map and the like so as to form a weather product; and finally, issuing and sharing the lightning information through a share network so as to analyze the product, and realizing the basic target of a lightning service by the lightning data space analysis method.

Description

technical field [0001] The invention belongs to the intersection field of GIS and meteorological information technology. The power of geographic information system (GIS) is that it can digitally store the spatial geographical distribution and its attributes, establish a data management system, and develop various analysis and processing functions at the same time, so as to quickly obtain information and display the processing results as a map. , primitives and data in the form of representation. Therefore, processing massive and complex real-time lightning data information can provide scientific means for lightning protection analysis and decision-making through the powerful spatial query analysis and graphic visualization functions of GIS, greatly improving the statistical efficiency of lightning data in various forms . Background technique [0002] The occurrence of lightning in nature is highly random, instantaneous and dangerous, and it is closely related to the strong...
