创建Shapefile文件并写入数据的例子

from osgeo import ogr
from osgeo import osr
import json
import os
os.environ['SHAPE_ENCODING'] = "utf-8"


with open('China.json') as f:
 china = json.load(f)

# 创建DataSource
driver = ogr.GetDriverByName('ESRI Shapefile')
ds = driver.CreateDataSource('China.shp')

# 创建WGS84空间参考
srs = osr.SpatialReference()
srs.ImportFromEPSG(4326)

# 创建图层
layer = ds.CreateLayer('province', srs, ogr.wkbPolygon)
# 添加属性定义
fname = ogr.FieldDefn('Name', ogr.OFTString)
fname.SetWidth(24)
layer.CreateField(fname)
fcx = ogr.FieldDefn('CenterX', ogr.OFTReal)
layer.CreateField(fcx)
fcy = ogr.FieldDefn('CenterY', ogr.OFTReal)
layer.CreateField(fcy)

# 变量GeoJSON中的features
for f in china['features']:
 # 新建Feature并且给其属性赋值
 feature = ogr.Feature(layer.GetLayerDefn())
 feature.SetField('Name', f['properties']['name'])
 feature.SetField('CenterX', f['properties']['cp'][0])
 feature.SetField('CenterY', f['properties']['cp'][1])

 # 设置Feature的几何属性Geometry
 polygon = ogr.CreateGeometryFromJson(str(f['geometry']))
 feature.SetGeometry(polygon)
 # 创建Feature
 layer.CreateFeature(feature)
 del feature
ds.FlushCache()

del ds
