GIS-based power-meteorology longitudinal association method and system

The invention discloses a GIS-based power-meteorology longitudinal association method and system. The method comprises the following steps: step one, meteorological data acquisition; to be specific, carrying out access of real-time monitoring and early warning data of the weather bureau to a power grid GIS platform; step two, meteorological data parsing; to be specific, carrying out conversion of the format of the collected meteorological data; step three: establishment of an equipment graph layer and a meteorological chart layer; to be specific, carrying out localization on power equipment and a monitoring station; and step four, matching of a meteorological chart layer with the equipment graph layer; to be specific, carrying out association of the meteorological chart layer and the equipment graph layer. Therefore, visual and omnibearing real-time monitoring of occurrence and development of disastrous weather like the typhoon, rainstorm, and severe convection and the like for the power equipment can be realized and the motion and evolution of the weather system also can be tracked, thereby providing an analysis basis for disastrous weather prediction.
