[AE] 空间分析-Intersect|Clip

求交思路：

以第一图层与第二图层相交为例：

1. 添加库

   using ESRI.ArcGIS.Geoprocessing;
   using ESRI.ArcGIS.AnalysisTools;
   

2. 获取图层

   ILayer pLayer1 = axMapControl1.Map.get_Layer(0) as ILayer;
   ILayer pLayer2 = axMapControl1.Map.get_Layer(1) as ILayer;
   

3. 设置输出路径

   string outPath = @"C:\buffer.shp";
   

4. 创建表格，用来存将要输入的参数

   IGpValueTableObject pObject = new GpValueTableObjectClass();
   object p1 = pLayer1 as object;
   object p2 = pLayer2 as object;
   pObject.SetColumns(2);
   pObject.AddRow(ref p1);
   pObject.AddRow(ref p2);
   

5. 创建地理处理

   Geoprocessor pGp = new Geoprocessor();
   pGp.OverwriteOutput = true;
   

6. 相交工具

   Intersect pIntersect = new Intersect();
   pIntersect.in_features = pObject; //输入参数
   pIntersect.out_feature_class = outpath; //输出路径
   pIntersect.join_attributes = "ALL"; //连接属性
   pGp.Execute(pIntersect, null); //执行
   

7. 刷新地图，显示

   axMapControl1.ActiveView.Refresh();
   

Clip运算：

ILayer pLayer = axMapControl1.get_Layer(0) as ILayer;
ILayer pLayer_2 = axMapControl1.get_Layer(1) as ILayer;
Geoprocessor pGP = new Geoprocessor();
pGP.OverwriteOutput = true;
ESRI.ArcGIS.AnalysisTools.Clip pClip = new ESRI.ArcGIS.AnalysisTools.Clip();
pClip.clip_features = pLayer; 
pClip.in_features = pLayer_2;
object output = "C:\\OutputServer\\Clip\\ClipResults.shp";
 pClip.out_feature_class = output;
pGP.Execute(pClip, null);
axMapControl1.ActiveView.Refresh();
