| 摘 要： | 制图区域内的地物状态是时间的函数,地物位置和属性的时空演化是地物状态的表征。根据地物位置和属性的时空变化,给出现势地物、消失地物和新生地物的定义。由于地图数据库是自动化制图的基础,维护数据库的现势性关系着地图的质量。论述地图数据的现势性检测,给出数据库的现势信息集、删除信息集和增补信息集的定义,对地图数据库更新给出数学表述。

| Abstract: | Geo-object state is function of time in the cartographic area,the time and space evolution of geo-object place and attribute is the expression of geo-object state.In this paper according to spatial and temporal change of geo-object place and attribute,the authors have given the definition of current geo-object,disappeared geo-object and newborn geo-object.Cartographic data base is the base of automatic cartography,so safeguarding the verisimilitude of data base is important for related map quality.The autho... |
