arcgis部分功能
在安装完AE和VS后,启动VS,新建项目,在控件工具栏看到列出的AE控件,主要会使用的是MapControl(数据视图)、PageLayoutControl(布局视图),TOOCControl(需设置与MapControl、PageLayoutControl和SceneControl的伙伴关系(buddy)),ToolbarControl(通过右键属性->Iems添加命令按钮)以及LisenceControl(每个窗体都必须加载,可以控制功能权限)。
也可以自己添加控件,需要添加引用及命名空间Controls,SystemUI
(1)实现打开地图,添加一button控件
//实现加载地图文档
OpenFileDialog openFileDialog=new OpenFileDialog();
openFileDialog.Title = "打开地图文档";
openFileDialog.Filter = "map document(*.mxd)|*.mxd";
openFileDialog.ShowDialog();
string filepath = openFileDialog.FileName;
if (axMapControl1.CheckMxFile(filepath))
{
axMapControl1.MousePointer = ESRI.ArcGIS.Controls.esriControlsMousePointer.esriPointerHourglass;
axMapControl1.LoadMxFile(filepath, 0, Type.Missing);
axMapControl1.MousePointer = ESRI.ArcGIS.Controls.esriControlsMousePointer.esriPointerDefault;
}
else
{
MessageBox.Show(filepath + "不是有效地地图文档");
}
(2)实现漫游
ICommand pCommand = new ControlsMapPanToolClass();
pCommand.OnCreate(axMapControl1.Object);
axMapControl1.CurrentTool = pCommand as ITool;
(3)全局视图
ICommand pCommand = new ControlsMapFullExtentCommandClass();
pCommand.OnCreate(axMapControl1.Object);
pCommand.OnClick();
(4)放大
ICommand pCommand = new ControlsMapZoomInToolClass();
pCommand.OnCreate(axMapControl1.Object);
axMapControl1.CurrentTool = pCommand as ITool;
(5)缩小
ICommand pCommand = new ControlsMapZoomOutToolClass();
pCommand.OnCreate(axMapControl1.Object);
axMapControl1.CurrentTool = pCommand as ITool;
(6)属性查询
ICommand pCommand = new ControlsMapIdentifyToolClass();
pCommand.OnCreate(axMapControl1.Object);
axMapControl1.CurrentTool = pCommand as ITool;
