ArcEngine 中使用 Geoprocessing

方法一、注意inputfeatrue和clipfeatureclass 裁剪顺序

  public static IFeatureClass Clip(IFeatureClass inputfeatrue,IFeatureClass  clipfeatureclass , string outFcName)
        {
            
            try
            {
                //开始剪切,设置容限值为0,系统默认容限值为当前DataFrame的空间域范围的1万分之一
                IBasicGeoprocessor basicGeoprocessor = new BasicGeoprocessorClass();
                basicGeoprocessor.SpatialReference = (clipfeatureclass as IGeoDataset).SpatialReference;
                //裁剪得到重叠的几何图形
                IFeatureClass outFeatureClass = basicGeoprocessor.Clip(clipfeatureclass as ITable, false, inputfeatrue as ITable, false, 0.01, IFeatureClassName outFeatureClassName);
                return outFeatureClass;
            }
            catch (Exception ms)
            {
                throw ms;
            }
        }

import com.esri.arcgis.geoprocessing.GeoProcessor;
import com.esri.arcgis.geoprocessing.tools.analysistools.Clip;
// Initialize the GeoProcessor 
GeoProcessor gp = new GeoProcessor();
Clip clip
= new Clip("c:/data/mjrroads.shp""c:/data/coasts.shp",  "c:/output/clipOutput.shp");
