摘要/Abstract

摘要： 针对农用地定级过程数据管理困难、计算量大、操作繁琐等问题，以ArcGIS engine/ArcSDE为基础构建农用地定级模型，使用ArcSDE和ADO.NET进行空间数据和属性数据的存取。在.NET平台和SQL Server数据库管理系统下，对模型实现的关键算法和技术作了研究和探索。通过该模型既实现了空间数据的有效管理和存储，也通过ArcGIS engine的强大接口，高效、精确地实现了农用地定级过程中的自动化操作，并且具有很高的通用性。实际应用表明该模型能够有效地完成农用地定级，并取得了良好的效果。

Abstract: In order to resolve the problems of data management difficult, large amount of computations, large amount of processing steps etc. in the process of agricultural land grading, so constructs a model of agricultural land grading based on ArcGIS Engine/ArcSDE, access spatial and attribute data by ArcSDE and ADO.NET.Under.NET platform and SQL Server database management system, it researches of model implementation on key arithmetic and technology. The model can efficiently manage and store spatial data, also can efficiently, accurately implement auto-manipulating based on the interface provided by ArcGIS engine in agricultural land grading process, and with high generality. Practical application shows that the model can efficiently complete the work of agricultural land grading, and achieve good results.
