本文演示了如何使用ArcGIS进行缓冲区分析。通过创建IFeatureLayer对象并调用AnalysisTools中的Buffer方法，设置输入要素、输出文件路径及缓冲距离等参数，实现了对地图上特定图层的要素进行3米范围的缓冲区生成。

            IFeatureLayer pFlyr = this.axMapControl1.get_Layer(0) as IFeatureLayer;
            ESRI.ArcGIS.Geoprocessor.Geoprocessor pGeoProcessor = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            ESRI.ArcGIS.AnalysisTools.Buffer pbuffer = new ESRI.ArcGIS.AnalysisTools.Buffer(pFlyr, @"C:\P_Buffer.shp", "3 Meters");
            pGeoProcessor.OverwriteOutput = true;
            ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult resultGeo = (ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult)pGeoProcessor.Execute(pbuffer, null);
            ESRI.ArcGIS.Geodatabase.IGPValue pV = resultGeo.GetOutput(0);

            IFeatureLayer pFlyr = this.axMapControl1.get_Layer(0) as IFeatureLayer;
            ESRI.ArcGIS.Geoprocessor.Geoprocessor pGeoProcessor = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            ESRI.ArcGIS.AnalysisTools.Buffer pbuffer = new ESRI.ArcGIS.AnalysisTools.Buffer();
            pbuffer.in_features = pFlyr;
            pbuffer.out_feature_class = @"C:\P_Buffer.shp";
            pbuffer.buffer_distance_or_field = "3 Meters";
            pGeoProcessor.OverwriteOutput = true;
            pGeoProcessor.Execute(pbuffer, null);
