Abstract
In order to increase the sharing and standardization of public land price spatial data,a hierarchical design concept for public land price spatial data has been proposed.The standardized public land price spatial data can effectively perform spatial data queries,positioning,retrieval,etc.,making it easier for land management departments to grasp the basic elements of local economic indicators such as benchmark land prices and calibrated land prices within their jurisdiction.关键词
