一、读取成都的边界坐标

http://datav.aliyun.com/portal/school/atlas/area_selector
从.json文件中读取边界坐标。
import json
import numpy as np
f = open(\'./data/chengdu2.json\',\'r\', encoding=\'UTF-8\')
data = json.load(f)
data_coordinates = data[\'features\'][0][\'geometry\'][\'coordinates\']
print(\'data_coordinates.shape:\', np.array(np.array(np.array(data_coordinates)[0])[0]).shape)

with open(\'./data/data6.txt\',\'w\') as ff:
    for i in range(0, 5):
        temp = np.array(np.array(np.array(data_coordinates)[i])[0])
        print(\'temp:\', temp.shape)
        for a in range(0, temp.shape[0]):
            ff.write(str(temp[a][0]) + \', \' + str(temp[a][1]) + \';\')
# with open(\'data.txt\',\'w\') as f:    #设置文件对象
#     f.write(str)                 #将字符串写入文件中
