摘　　要：由于CAD数据模型的限制以及与GIS矢量数据模型之间的不兼容,使得转换后GIS数据常出现许多质量问题。提出了CAD数据模型转换到GIS矢量数据模型的关键问题,并对能够匹配、如何匹配等问题进行了分析;此外,提出了GIS质量检查的指标体系,包括完整性、准确性、一致性三类,并深入分析了各种质量问题产生的阶段及原因。Due to Limitation of CAD data model and incompatibility relative to GIS vector data model, the transformed GIS data had many quality problems. The paper proposed the key problems of transformation from CAD data model to GIS vector data model, and analyzed the problems like how to be able to match, how to match. The paper also proposed the index system of GIS quality check that includeing integrity, accuracy, consistency. Finally, the paper analyzed deeply causation and phase that probably give arise to various quality problems.
