When more layers are overlapped in the map, the request pressure of the client is higher, and the number of concurrent requests exceeds the limit of the number of browser requests, so that the requests are queued. Network speed is limited and the client waits longer when receiving a large number of tiles. The service needs to be issued for different roles independently, the service quantity is huge, and the maintenance is not facilitated. When the data volume is large, the service end takes longer time for carrying out attribute or space filtering dynamic query for different roles, and the attribute filtering condition is unfavorable for maintenance when the service is complex.
