本文介绍了一个使用ArcGIS进行空间数据交集操作的例子。通过IFeatureClass接口实现两个要素类之间的交集，并将结果保存到指定路径下的Shapefile文件中。此过程涉及设置输出特征类的属性、定义工作空间及利用BasicGeoprocessor类来执行交集操作。

public IFeatureClass Intsect(IFeatureClass _pFtClass,IFeatureClass _pFtOverlay,string _FilePath,string _pFileName)
{

IFeatureClassName pOutPut = new FeatureClassNameClass();

pOutPut.ShapeType = _pFtClass.ShapeType;

pOutPut.ShapeFieldName = _pFtClass.ShapeFieldName;

pOutPut.FeatureType = esriFeatureType.esriFTSimple;

//set output location and feature class name

IWorkspaceName pWsN = new WorkspaceNameClass();

pWsN.WorkspaceFactoryProgID = "esriDataSourcesFile.ShapefileWorkspaceFactory";

pWsN.PathName = _FilePath;

//也可以用这种方法,IName 和IDataset的用法

/* IWorkspaceFactory pWsFc = new ShapefileWorkspaceFactoryClass();

IWorkspace pWs = pWsFc.OpenFromFile(_FilePath, 0);

IDataset pDataset = pWs as IDataset;

IWorkspaceName pWsN = pDataset.FullName as IWorkspaceName;
*/

 

 

IDatasetName pDatasetName = pOutPut as IDatasetName;


pDatasetName.Name = _pFileName;

pDatasetName.WorkspaceName =pWsN;

IBasicGeoprocessor pBasicGeo = new BasicGeoprocessorClass();

IFeatureClass pFeatureClass = pBasicGeo.Intersect(_pFtClass as ITable , false, _pFtOverlay as ITable , false, 0.1, pOutPut);


return pFeatureClass;
