GIS软件设计与实现实验报告姓名： 王兴平 班级： 测绘1103班 学号： 0145110620 指导老师： 李光强 2015/1/5实验一 数据加载与图层控制一、实验目的1.了解组件ArcEngine9.3开发环境的构建，以及相关软件的安装；2.掌握AE组件实现数据加载、缩放、平移等简单的功能；3.掌握程序代码实现数据加载、缩放、平移、拉窗放大等功能；4.掌握使用程序代码控制图层可视性、图层移动、图层移除等操作。二、实验准备完成时间：2学时预备知识：实验的操作系统环境为 Windows XP以上操作系统，要基于ArcEngine进行应用开发，系统中需要安装有：ArcGIS 9.3、ArcEngine 9.3和C#2005以上版本相应软件。实验数据：文件夹“中国地图”三、实验步骤及方法1 创建C#工程，添加窗体及相关AE组件，窗体设计如下图所示：运行程序，并点击工具栏上按钮，记录各功能按钮的操作。2.利用程序代码添加SHP文件，并完成SHP加载、地图缩放、全图、平移、拉窗放大等操作，设计界面如下图所示：要求：1）工具栏上的“打开”按钮，功能是通过打开文件对话框，允许一次加载多个SHP文件，而且在对话框中仅显示SHP文件；2）平移、放大、缩小功能按钮的操作顺序过程必须是用户先点击按钮，然后再点击地图时才完成相应功能操作；3）工具栏上的最后一个按钮为拉窗放大，即用户点击该按钮时，在地图可以画出一个矩形，然后将矩形内的地图放大。3.使用程序代码控制图层可见性及移动图层，界面设计如下图所示：注意：1）工具栏后四个按钮依次为：上移选中图层、下移选中图层、移除选中图层操作；2）图层列表里，依据图层是否选中而设置图层的可见性。4为地图添加右键菜单，在右键菜单中实现全图、平移、放大、缩小、信息（identity）功能，使用鼠标中键实现地图平移。五实验主要代码private void LoadFile_Click(object sender, EventArgs e) OpenFileDialog dlg = new OpenFileDialog(); dlg.Filter = Shape file(*.shp)|*.shp; dlg.Title = 打开 Shape数据文档; dlg.Multiselect = true; /定义存放打开 IFeatureClass 的字符串数组 string FilePath; if (dlg.ShowDialog() = DialogResult.OK) FilePath = new stringdlg.FileNames.Length; FilePath = dlg.FileNames; if (FilePath.Length 0) string WorkSpacePath = System.IO.Path.GetDirectoryName(FilePath0); string ShapeFilePath = new stringFilePath.Length; /获得打开 IFeatureClass 的字符串数组 for (int i = 0; i FilePath.Length; i+) ShapeFilePathi = System.IO.Path.GetFileName(FilePathi); IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactoryClass(); IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(WorkSpacePath, 0); IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace; for (int i = 0; i ShapeFilePath.Length; i+) IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(ShapeFilePathi); IDataset pDataset = pFeatureClass as IDataset; IFeatureLayer pFeatureLayer = new FeatureLayerClass(); pFeatureLayer.FeatureClass = pFeatureClass; pFeatureLayer.Name = pDataset.Name; ILayer pLayer = pFeatureLayer as ILayer; this.axMapControl1.Map.AddLayer(pLayer); this.axMapControl2.Map.AddLayer(pLayer); 实验2 地图符号化与专题制图一、实验目的1.掌握图层的符号化操作；2.掌握专题制图的常用方法以及基本算法。二、实验准备完成时间：2学时预备知识：实验的操作系统环境为 Windows XP以上操作系统，要基于ArcEngine进行应用开发，系统中需要安装有：ArcGIS 9.3、ArcEngine 9.3和C#2005以上版本相应软件。学习C#中的ListView控件的使用方法和颜色拾取对话框的使用，以及ArcEngine中的颜色定义的方法。实验数据：文件夹“中国地图”三、实验步骤及方法2 利用程序代码实现点状要素图层的符号化，界面如图1所示：图1要求：1） 点击“点符号化”按钮时需要判断当前选中的图层是否为点状图层；2） 选中的图层为点状图层以后，弹出如图2所示符号设置对话框：图2提示：符号列表框为ListView控件，点击颜色按钮时，弹出颜色拾取对话框，如图3：图33） 在符号选择器中，点击确定后，将根据设置完成点图层的符号化。2.在图1所示的界面中，点击“面符号化”，完成所选择面状要素图层的符号化。要求：1） 在点击事件中，需要判断当前选择的图层是否为面图层；2） 在程序代码中实现指定符号填充和颜色设定。3.完成单值渲染操作，如图4。图44.完成分级渲染操作，如图5。图55.选做：在TOC控件中添加快捷菜单，并在其中添加“图层属性”选项，在点击该选项时，弹出如图6所示的图层属性对话框，并在其中的Symbol选项卡中完成专题制图设置工作。四实验主要代码MapOperations mapOp;
