第一章 利用Python将csv文件转换为shp

csv文件中记录了480行地铁站的信息

我们需要做的是利用Fiona包，将csv的内容读取，并导出为shp格式

import fiona
from collections import OrderedDict
import csv
from fiona.crs import from_epsg


with open("./subway_289上海市.csv", 'r') as csvfile:
    reader = csv.reader(csvfile)
    rows = [row for row in reader]
#print(rows)

subway_schema = {'geometry': 'Point', 'properties': OrderedDict([('num','int'), ('poi_name', 'str'), ('route_name','str'),
                                                                 ('city_name', 'str')])}
subway_infor = []
for i in range(1, len(rows)):
    lon = float(rows[i][3])
    lat = float(rows[i][4])
    infor = {'geometry':{'type':'Point', 'coordinates':(lon,lat)},
             'properties':OrderedDict([('num', int(rows[i][0])), ('poi_name', rows[i][1]), ('route_name', rows[i][2]),
                                       ('city_name', rows[i][5])])}
    subway_infor.append(infor)
output = fiona.open('./subway_289上海市.shp', 'w', encoding = 'utf8', driver= 'ESRI Shapefile',
                    crs = from_epsg(4326), schema = subway_schema)
print(subway_infor)
output.writerecords(subway_infor)
output.close()
