简要说明

在java，利用gdal，将裁剪范围的shpfile 对 目标shpfile 进行裁剪；前置条件是两个shpfile处于一个坐标系下，不然裁剪结果可能为空。

maven依赖

<!--需要安装完gdal后，本地install gdal包才能使用 -->
		<!--gdal安装可参考 https://blog.csdn.net/qq_41613913/article/details/135743562 -->

样例代码

public static void main(String[] args) {
    //临时的裁剪结果目录
    String clippingParentDirFileStr = "D:/tmp/clipping" + File.separator ;
    //将裁剪范围shp文件
    String clipfilePath = "D:/data/clipping.shp";
    //读取shp文件
    DataSource clipShpDs = ogr.Open(clipfilePath, 0);
    //单图层过滤
    Layer shpFilterLayer = clipShpDs.GetLayer(0);

    org.gdal.ogr.Driver shpDriver = ogr.GetDriverByName("ESRI Shapefile");
    if (shpDriver == null) {
        System.out.println("shpfile 驱动不可用");
        return;
    } 
    String originalFilePath = "D:/data/xxx.shp";

    String originalName = cn.hutool.core.io.FileUtil.getName(originalFileStr);
    String layerName = originalName.replace(".shp", "");
    Layer originalLayer = originalDataSource.GetLayer(layerName);
    //判断裁剪文件的坐标系和源数据坐标系是否一致
    SpatialReference shpFilterSpatialReference = shpFilterLayer.GetSpatialRef();  
    String shpFilterSrid = shpFilterSpatialReference.GetAttrValue("AUTHORITY", 1);
    String originalSrid = originalLayer.GetSpatialRef().GetAttrValue("AUTHORITY", 1); 
    if(!shpFilterSrid.equals(originalSrid)) {
         System.out.println("两个shp的坐标系不一样")
         return;

            layerOut.CreateField(defn);
        }

        //遍历图层每个几何
        long featureCount = originalLayer.GetFeatureCount();
        long filterFeatureCount = shpFilterLayer.GetFeatureCount();
        Feature feature1 = null;
        Feature feature2 = null;
        for (int i = 0; i < filterFeatureCount ;i++) {
            feature1 = shpFilterLayer.GetFeature(i);
            Geometry geometry1 = feature1.GetGeometryRef();

            for (int j = 0 ; j < featureCount ;j++) {
                feature2 = originalLayer.GetFeature(j);
                Geometry geometry2 = feature2.GetGeometryRef();
                if (geometry1.Intersect(geometry2)) {
                    Geometry intersection = geometry1.Intersection(geometry2);
                    feature2.SetGeometry(intersection);
                    layerOut.CreateFeature(feature2);
                }
            }
        }

        originalLayer.delete();
        shpFilterLayer.delete();
        layerOut.delete();
