基于ArcGIS Engine的水深点与等深线检查方法及实现

Inspection Method and Realization of Water Depth Point and Bathymetric Contour Based on ArcGIS Engine

对水下地形图数据制作过程中经常出现水深点与等深线的点线矛盾问题解决方法及实现进行了研究。首先提出水深点与等深线矛盾的检查方法和思路;分析了它们之间的矛盾逻辑关系;其次提出了使用不规则三角网检查法前对拟检查数据进行区域分区;最后使用C#语言在.NET平台中结合ArcGIS Engine组件,开发了对gdb、mdb格式的数据进行检查的程序,并且程序在不影响数据检查结果下运行更加高效,还分析了方法的可行性。

In the process of making underwater topographic map data,the solution and realization of the point-line contradiction problem which often appears between water depth point and contour are studied.Firstly,the inspection method and thinking of water depth point and contour contradiction are proposed,and the contradictory logical relationship between them is analyzed.Secondly,it proposes to partition the area for the to be inspected data before using the inspection method of irregular triangulation network.Finally,it uses the C# language in the.NET platform to combine with ArcGIS Engine component,develops the inspection program for the data of GDB,MDB format,and the program runs more efficiently without affecting the data inspection results.It also analyzes the feasibility of the method.
