Abstract

The invention relates to a GIS (geographic information system)-platform based dynamic loading method for real-time weather of graticule data. The method includes the following steps: writing and deploying a GIS platform rear-end server code, partitioning a GIS platform measured area by a parallel area partitioning algorithm automatically generated by finite-element grids to form a graticule, acquiring whether information in real time, and accurately checking scope and condition of influences of extreme weather on power-grid factors by a graticule framework at a GIS platform front-end. High automation degree of geographic area grid partition is achieved, requirements on space data diversity and resource dynamics are met, and GIS platform operation efficiency is not affected. The scope and the condition of the influences of the extreme weather on the power-grid factors are accurately checked to acquire useful data in power-grid resources or weather information, so that loading of useless data is avoided, and the GIS platform operation efficiency is improved.

Description

(1) Technical field [0001] The invention relates to GIS technology, in particular to a method for real-time meteorological dynamic loading of geographic grid data based on a GIS platform, related to a parallel area division algorithm automatically generated by finite element grids. (2) Background technology [0002] Geographic grid is a scientific and concise positioning reference system, which is a supplement to the existing measurement reference system, administrative division reference system and other special positioning systems. The geographic grid system originated from early cartographic research, and developed into a basic method for expressing complex geographic phenomena, comprehensively analyzing natural and human data, and simulating the functions and behaviors of geographic systems. The composition of the geographic grid system includes grid cells, grid edges, and grid points. The grid cells represent the regional surface characteristics, the grid points determi...
