gdal2.0.3读取wfs服务

[刘颖-GIS]

1、ArcGIS发布wfs服务，通过QGIS测试服务正常；


2、gdal编译需要对wfs支持，在本人另外一篇帖子上已经做了介绍（以下为测试代码）；
const char* pszDriverName="WFS";
GDALDriver *poDriver;
GDALDriver *poDriverShp;
OGRRegisterAll();
poDriver=GetGDALDriverManager()->GetDriverByName(pszDriverName);
poDriverShp=GetGDALDriverManager()->GetDriverByName("ESRI Shapefile");

if (poDriver==NULL)
{
AfxMessageBox(_T("驱动加载失败！"));
return;
}
//加载wfs服务
OGRDataSource *poDS = NULL;
poDS = (OGRDataSource *)GDALOpenEx("WFS:http://192.168.1.101:6080/arcgis/services/2014shp/MapServer/WFSServer",GDAL_OF_VECTOR,NULL,NULL,NULL);

OGRLayer *pLayer = NULL;
OGRLayer *pLayer2 = NULL;
OGRLayer *pLayerUnion = NULL;

OGRSpatialReference *pSpatialRef;

char **wkt;
OGRFeature *pFeature;
//获取wfs服务图层对象
pLayer = poDS->GetLayer(0);
pLayer2 = poDS->GetLayer(1);

//创建输出shp图层，用于测试
GDALDataset *poDSOUT;
poDSOUT = poDriverShp->Create( "d:\\test\\out.shp", 0, 0, 0, GDT_Unknown, NULL );
if( poDSOUT != NULL )
{
pLayerUnion = poDSOUT->CreateLayer("out",pLayer->GetSpatialRef(),pLayer->GetGeomType(),NULL);
}
//wfs图层合并到本地shp图层
pLayer->Union(pLayer2,pLayerUnion,NULL,NULL,NULL);
pLayerUnion->SyncToDisk();
GDALClose(poDSOUT);
GDALClose(poDS);
3、QGIS加载本地输出图层正常。
