摘要:
规则格网DEM的流向确定是分布式水文模型的一个关键问题。无限流向法是对D8方法以及多流向算法的折中。地理信息科学等学科的不断发展，对DEM数据库访问技术提出了更高要求。作为Microsoft数据库应用程序开发的新接口，ADO（Active Data Object）技术是建立在OLE DB之上的高层数据库访问技术，ADO数据库技术也是现在最快速的数据库访问中间层。详细介绍了无限流向法的算法思想，重点论述了在Visual C++6.0平台下使用ADO技术访问Visual FoxPro格式的DEM数据库表的过程。研究表明ADO技术可以很好的用于数据库的访问，是未来DEM数据及其它地理信息数据存储的发展方向。
Abstract:
The determination of flow direction in regulate grid DEM is a key problem in distributed hydrological model based DEM. Deterministic infinite algorithm is a eclectic algorithm between D8 and multiple flow directions. The expedite development of geography science call for advanced data base access technology. As the new interface of Microsoft data base application program developing, ADO is an advanced database programming technique based on OLE DB, it also is most rapid access interface. First the authors give a presentation of the idea of deterministic infinite algorithm. Then expound the process of DEM database form access using ADO technique in Visual C++6.0 platform. At last, the future about application of ADO in database access is discussed.
