java 利用gdal，将shpfile转为gdb的图层_gdal java gdbdriver.createdatasource

简要说明

在java开发中，利用gdal将shp转为gdb的一个图层

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) {
        // 注册所有的驱动
        ogr.RegisterAll();
        // 为了支持中文路径，请添加下面这句代码
        gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8","YES");
        // 为了使属性表字段支持中文，请添加下面这句
        gdal.SetConfigOption("SHAPE_ENCODING","CP936");

        String strVectorFile = "D:\\shp\\xxx.shp";

        DataSource ds = ogr.Open(strVectorFile,0);
        Layer layer = ds.GetLayer(0);
        String authority = ds.GetLayer(0).GetSpatialRef().GetAttrValue("AUTHORITY", 1);
        System.out.println("坐标系: " + authority);
        if (ds == null)
        {
            System.out.println("打开文件失败！" );

        Feature feature = null;
        //针对fid等于0的情况做处理
        while ((feature = layer.GetNextFeature()) != null)
        {
            feature.SetFID(1 + feature.GetFID());
            gdbLayer.CreateFeature(feature);
        }
        
        dataSourceGDB.delete();
        gdbDriver.delete();
