[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0048] Such as figure 1 As shown, an intelligent spatial data object modeling method applied to road system spatial data resource management includes the following steps:
[0049] Step 1: abstract the road system spatial data resources, and create road business model objects: the road system space data resources include road centerlines, planned road surfaces and road details of various grades and categories; the road business model Objects include: road centerline (road_object), planned road surface (road_part), road details (road_detail);
[0050] Defining a spatial model object is represented as a spatial data table from the perspective of database storage. In this method, defining the attribute information of a spatial model object mainly includes:
[0051] ●Description of basic data types, including basic data (library) types and extended types; ...
