Visual display method and system for geospatial data

The invention relates to the technical field of geographic information systems, and discloses a visual display method and system for geographic spatial data, and the method comprises the steps: obtaining a JSON configuration object sent by an external JS browser quoting a two-dimensional and three-dimensional map API package through an NPM package manager, and initializing a map component in a corresponding div element according to the JSON configuration object; obtaining a map layer object sent by the external JS browser through the two-dimensional and three-dimensional map API packet, and adding the map layer object to a map component; and loading the map layer object in the map component in a preset layer loading mode so as to realize visual display of the geographic space data. According to the method, the technologies of various map frames are integrated, and rapid conversion and adaptation among different map frames are realized on the upper layer in a unified JSON object configuration mode, so that map
