shapefile转换geojson

import shapefileimport codecsfrom json import dumps# read the shapefiledef 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')
