Abstract

This invention belongs to the field of geospatial intelligent analysis methods, specifically a method for automatically constructing multi-scale dynamic spatiotemporal geographic maps based on vector data. It includes the following steps: S1, data standardization and basic spatial relationship calculation; S2, spatiotemporal integrated geographic entity modeling and map updating; S3, road network-enhanced spatial relationship modeling, integration, and map updating; S4, automatic construction of multi-scale geographic hierarchical systems and map updating; S5, map output. The execution of steps S1 to S4 is driven by an intelligent agent module, which dynamically adjusts the execution order and parameters of each step. This invention achieves end-to-end automated construction of geographic knowledge maps with dynamic spatiotemporal reasoning capabilities from multi-source, multi-period vector data, supports full lifecycle tracking of geographic objects, upgrades traditional geometric relationships to real and quantifiable path semantic relationships, and realizes cross-level spatial cognition and reasoning functions.
