shapefile转换geojson

import shapefile

import codecs

from json import dumps

# read the shapefile

def shp2geo(file="line出产.shp"):

  reader = shapefile.Reader(file)

  fields = reader.fields[1:]

  field_names = [field[0] for field in fields]

  buffer = []

  for sr in reader.shapeRecords():

    record = sr.record

    record = [r.decode('gb2312', 'ignore') if isinstance(r, bytes)

        else r for r in record]

    atr = dict(zip(field_names, record))

    geom = sr.shape.__geo_interface__

    buffer.append(dict(type="Feature", geometry=geom, properties=atr))

    # write the GeoJSON file

  geojson = codecs.open(file.split('.')[0] + "-geo.json", "w", encoding="gb2312")

  geojson.write(dumps({"type": "FeatureCollection", "features": buffer}, indent=2) + "\n")

  geojson.close()

if __name__ == '__main__':

  # import os

  # for z,x,c in os.walk('.'):

  #  for zz in c:

  #    if zz.endswith(".shp"):

  #      shp2geo(zz)

  # shp2geo(file='D.shp')

  shp2geo(file='ttttttttttt.shp')
