Research on Online Updating Method of Vector Electronic Maps
Taking"Map World·Zhejiang"as the research object,this paper studied the online update technology of vector electronic map data.Mapbox vector tile technology was used to improve the rendering efficiency of large-scale vector data.The efficient scheduling of vector tiles was realized by using the advantage of Redis cache in high access quantity.Vector data node snap technology was used to improve the efficiency of feature online editing.The Rocket MQ message queue was used to ensure the system stability in the multi-concurrent environment.Through the above key technologies,the online update module of electronic maps was developed,and a county-level city in Zhejiang Province was taken as a pilot area to carry out the practice of element update,which verified the efficiency of the online update method of electronic maps.
