shapefile转换geojson
我要评论
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')
