本文介绍了一种使用ArcGIS进行空间连接(Spatial Join)的方法，通过C#代码实现将两个地理空间数据集根据它们的空间关系进行连接。此过程能够帮助用户理解如何设置目标特征、连接特征、输出特征类以及其他关键参数。

废话不多说，code是王道。

其中str1、str2两个参数是target路径、join路径

private void spatialJoin(Geoprocessor gp, string str1, string str2)

{
ESRI.ArcGIS.AnalysisTools.SpatialJoin sj = new ESRI.ArcGIS.AnalysisTools.SpatialJoin();

saveName("spatialJoin", getFileName(str1) + "_SpatialJoin.shp");

sj.target_features = str1;

sj.join_features = str2;

sj.out_feature_class = getPathName(str1) + "_SpatialJoin.shp";

sj.join_operation = "JOIN_ONE_TO_ONE";

sj.match_option = "INTERSECTS";

sj.join_type = "KEEP_ALL";

if (sj.join_features != null || sj.target_features != null)
{
IGeoProcessorResult results = null;

results = (IGeoProcessorResult)gp.Execute(sj, null);

IGPUtilities pGPUtil = new GPUtilitiesClass();

IFeatureClass pFC;

IQueryFilter pQF;

pGPUtil.DecodeFeatureLayer(results.GetOutput(0), out pFC, out pQF);

int count = pFC.FeatureCount(null); //统计Feature对象个数

IFeatureCursor pCursor = pFC.Insert(true); //提取FeatureCursor对象

IFeatureLayer pFeatureLayer = new FeatureLayerClass();

pFeatureLayer.FeatureClass = pFC;

axMapControl1.Map.AddLayer(pFeatureLayer);

result5.Text = "Spatial Join 完成！";

}
else
MessageBox.Show("请选择图层");
}
