| Abstract: | 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. |
