矢量地图数据属性精度的检查与控制

The Check and Control of Attribute Accuracy of Vector Map Data

介绍了地图属性数据的质量特征 ,属性数据质量检查与控制的依据 ;给出了属性精度的评价模型、内部数据结构 ;较详细地论述了属性数据正确性的检查方法。

The attribute data is one of the most important contents of vector map data, whose quality directly affects the application of map data. This paper introduces the quality characteristics of map attribute data and the gist of checking and controlling attribute data quality. It offers the model for evaluating the attribute accuracy and the interior data structure. It also discusses the methods of checking the correctness of the attribute data in detail.
