摘要
概述了地名、地名数据库以及时空数据模型的定义及其发展现状,提出了适合地名时空语义表达的地名时空数据模型。应用这个模型实现了对地名数据库的编辑更新及时空查询操作。本文以地名为例研究了点状目标的时空数据模型,丰富了时空数据模型理论。
Place name, place name database and spatial - temporal data model are described in this paper. A place name spatial -temporal data model is presented for expression of spatial -temporal semantics. The application of the model can realize editing, updating and spatial - temporal querying of the place name database. Current resear- ches on the spatial -temporal data model are mainly focused on polygonal parcels features. The spatial -temporal data model of point features is dealt with in this paper, and the result enriches the theory of the spatial - temporal data model.
