| 摘 要： | 空间数据对于地理信息系统就如同汽油对于汽车一样重要。空间数据的质量更是地理信息系统分析结果不否准确和合理的重要因素。因此根据质量评价方法的不同，提出了相应的空间数据质量模型，并进而提出空间数据质量的度量模型，这对科学、合理地进行数据质量评定及准确、统一的质量表达将起到概念级指导意义。

| Abstract: | Spatial data for geographic information system is as important as the petrolfor vehicle. Spatial data quality is more important factor for ev aluating the analysisresults if they are correct or reasonable in GIS. In this paper, a spatial data qualitymodel is presented according to the method used fo r evaluating the spatial data quality,and a measurement model of spatial data q uality is also given. Both two models, which areused for scientific and reasona ble assessment of data quality as well as exact andunitary representation of da ta quality, are of great importance at conceptual level. |
