    摘要:

    土壤侵蚀普查是第一次全国水利普查的主要目标之一,为获得野外调查单元数据,需充分利用密度抽样方法和大量的野外调查单元底图以辅助野外调查,并采用空间分析方法从已获取的调查数据中计算各侵蚀因子。但我国幅员辽阔,土壤侵蚀范围广,抽样调查点的数量也随之增大,制图过程中数据量大,制图流程较为繁杂。运用C#语言、Visual Studio 2008开发工具和ArcEngine组件式二次开发实现了土壤侵蚀抽样调查单元底图的自动制图。详细介绍了自动制图过程中各部分功能的设计和实现思路。通过编程实现地图数据的自动裁剪,计算与分类,地图排版以及打印输出,极大减轻了制图工作量。

    Abstract:

    Soil erosion survey is one of the main tasks in the first national water resources survey.To obtain the field investigation unit data,substantive ground sampling need to be made,and a large number of base map for field investigation unit are required to assist field investigations.Then spatial analysis will be adopted to get various erosion factors by using the acquired data.Since China has a very vast area and erosion area,the number of field investigation unit base map is huge.The procedures of base map cartography,which involves amounts of data,are usually cumbersome and repetitive.Therefore,this paper studied the implementation of automated mapping on soil erosion sampling survey unit base maps by using C# programming,Visual Studio 2008and ArcEngine component-based development.By programming,this study achieved automated mapping,as map clipping,calculation,classification,layout and printing could be done automatically.This study also elaborately described the functions and concept in automatic cartography in three sections:map clipping,map projection and map layout.
