This pattern includes multi-scale cascade updating and multi-industry collaboration updating, and is strongly supported by two key techniques entity level increment updating and geographic entity encoding. Linkage updating guaranteed updating efficiency and consistency of geospatial data in Zhejiang Geospatial Data Exchange.
