城市网格化管理是一种数字化城市管理模式,是我国数字城市技术应用领域的重大突破,在国际上处于领先地位,对其部件数据质量评价与控制具有重要的现实意义。针对城市网格化管理部件数据的地域性分布特点,运用空间插值算法,提出一种基于数字地面模型（DTM）的城市网格化管理部件数据质量评价方案（以上海市为例）。实验结果表明,该方案更能准确的度量整体数据的质量。

英文摘要：

Urban grid management is a digital urban management model and a great breakthrough in the application of digital city technology in our country,and takes the lead in the world,presently it is being carried out in the whole country. It has great practical significance for quality evaluation and control of component data. In view of the regional distribution characteristic of component data in urban grid management,combining spatial data interpolation algorithms,this paper proposes a quality evaluation program for components data in urban grid management based on digital terrain model （DTM）——taking Shanghai as an example. The experimental results prove that the program is more accurate to measure overall data quality.
