A network topology geospatialization expression method fusing force-directed layout and hierarchical mapping and related equipment

Abstract

The application provides a network topology geospatialization expression method combining force-directed layout and hierarchical mapping and related equipment, and is applied to the field of data processing. The network spatial element data containing node, edge and hierarchical attribute and the geographic spatial data are taken as input, the repulsion, attraction and resultant force formulas are defined based on the force-directed layout algorithm in combination with algorithm parameters, the node position is iteratively updated to convergence, the layout constraint and the target function are applied to generate a two-dimensional network logical topology graph; the network elements are classified and processed to generate visual results; then the network space is divided according to the geographic spatial hierarchy and multi-scale, the three-dimensional topology structure is constructed in combination with the hierarchical mapping strategy; finally, the three-dimensional model data of the building is fused, the facility distribution and the machine room topology association are simulated, the symbolization constraint and the flow association target are applied, the interactive interface and multi-dimensional results are generated, and the network topology geospatialization information is output.
