[人工智能]Python 将成都进行网格化

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
