WebGIS development architecture system based on Openlayers

The invention discloses a WebGIS development architecture system based on Openlayers, and the system comprises the following modules: an obtaining module which is used for obtaining standard slice map data with a plurality of hierarchies from various data sources of a map; the data processing module is used for carrying out format conversion on the slice map data obtained by the various data sources and converting the slice map data into a uniform format; the map loading module is used for determining a to-be-loaded area according to the central position of the map displayed on the current display interface, and loading the processed to-be-loaded area slice map according to the current map scale; the dynamic rendering module is used for performing coordinate system conversion on the vector layer according to a coordinate system of the slice map, rendering the current slice map by using the vector layer, and generating a vector slice map for vector marking; and the configuration module is used for intelligentl
