摘要:
基于数字地图要素位置特征的数学模型,将Baarda的可靠性理论扩展应用于GIS空间数据库中图形数据的可靠性评价. 针对点、线、曲线三种基本数字制图要素,导出了相应的可靠性公式,并获得了可靠性分布的三角形和梯形图. 通过对某城市GIS 空间数据库中道路层上部分数据的分析,说明了实际应用本成果的具体方法.
Abstract:
Based on the mathematical model on the positional features of the digit terrain condition, this paper extends the Baarda’s reliability theory to assess the reliability of graph data in GIS database. The paper derives the reliability formulas according to three basic digit drawing features of the corresponding point, line and curve, obtains the triangle and trapezoid images of the reliability distribution. Through the analyses of some road layer’s data in GIS spatial database of one city, the paper illustrates the concrete methods about how the achievement is used in application.
