//shp to geojson
首先拿到SimpleFeatureCollection,然后写入geojson
MapconnectionParams = new HashMap();
connectionParams.put("DriverName", "GeoJSON");
connectionParams.put("DatasourceName", file.getAbsolutePath());
OGRDataStoreFactory factory = new JniOGRDataStoreFactory();
OGRDataStore dataStore = (OGRDataStore)factory.createNewDataStore(connectionParams);
dataStore.createSchema(features, true, null);//核心一句
//shp2json
from osgeoimport gdal
from osgeoimport ogr
def shp2gson():
# 为了支持中文路径，请添加下面这句代码
gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8", "NO")
# 为了使属性表字段支持中文，请添加下面这句
gdal.SetConfigOption("SHAPE_ENCODING", "")
strVectorFile ="E:\\example.shp"
# 注册所有的驱动
ogr.RegisterAll()
# 打开数据
ds = ogr.Open(strVectorFile, 0)
if ds ==None:
print("打开文件【%s】失败！", strVectorFile)
return
print("打开文件【%s】成功！", strVectorFile)
driver = ogr.GetDriverByName("GeoJSON")
if driver ==None:
print("打开驱动失败！")
driver.CopyDataSource(ds, "E:\\fibercable.geojson")
if __name__ =='__main__':
shp2gson()
//geojson to shp
直接从geojson中拿到FeatureCollection，剩下的就是怎么写入shp文件
InputStream in = new FileInputStream(geojson);
FeatureJSON fjson = new FeatureJSON(gjson);
SimpleFeatureCollection fc = (SimpleFeatureCollection)fjson.readFeatureCollection(in);
MapParams = new HashMap();
Params.put("DriverName", "ESRI Shapefile");
Params.put("DatasourceName", shpFile.getAbsolutePath());
OGRDataStoreFactory factory2 = new JniOGRDataStoreFactory();
OGRDataStore dataStore2 = (OGRDataStore) factory2.createNewDataStore(Params);
dataStore2.createSchema(fc, true, null);
dataStore2.dispose();
方法二qgis 太简单了，两句话，qgis封装的好，底层也是ogr
layer=QgsVectorLayer(shpfile,'shp','ogr')
err=QW.writeAsVectorFormat(layer,geojsonfile,'utf-8',None,'GeoJSON')
//parse Feature or FeatureCollectionFeaturefeature=(Feature)GeoJSONFactory.create(json);FeatureCollectionfeatureCollection=(FeatureCollection)GeoJSONFactory.create(json);//parse Geometry from FeatureGeoJSONReaderreader=newGeoJSONReader();Geometrygeometry=reader.read(feature.getGeometry()); geometry=reader.read(featureCollection.getFeatures()[0].getGeometry());//create and serialize a FeatureCollectionListfeatures=newArrayList();Mapproperties=newHashMap(); features.add(newFeature(geometry, properties);GeoJSONWriterwriter=newGeoJSONWriter();GeoJSONjson=writer.write(features);
