Three-dimensional distribution display method and system based on GIS (Geographic Information System)

The invention relates to the field of three-dimensional display, in particular to a GIS-based three-dimensional distribution display method and system, and the method comprises the following steps: S1, a GIS system collects geographic data and outputs various three-dimensional topographic maps, and a meteorological system collects meteorological data and outputs various three-dimensional meteorological maps; s2, various data and graphs of the GIS system and the meteorological system are transmitted to the cloud platform for storage; s3, the cloud platform unifies the space coordinates of the GIS system and the meteorological system, and combines the space coordinates of the GIS system and the meteorological system to form a three-dimensional topographic map with meteorological data; s4, the cloud platform sends the three-dimensional geography and meteorological distribution map to the portable terminal through the wireless communication module; and S5, the user carries out various operations on the three-dime
