运行
只需要把url中的key换成自己申请的即可，本次是以步行来示例
od.txt为起始点坐标，可以输入多个od点获得多条路径
od_result.txt是输出的拐点结果，需要进arcgis转线
'''this demo based on Gaode API to plan the route'''import jsonfrom urllib import request
line=open('od.txt').read().splitlines() #the load is the demo's load#to create the api,and u need to apply the key,to choose your ways,the example for walkingurl='https://restapi.amap.com/v3/direction/walking?&origin={0}&destination={1}&key=请输入自己申请的key'pts=[] #create the variable to save the point of routeorder=1 #order to arcgis
for dis in line: origin=dis.split(';')[0] #origin point destination = dis.split(';')[1] #destination point html = request.urlopen(url.format(origin,destination)).read() js = json.loads(html)
duration=0 steps=js['route']['paths'][0]['steps'] dis=js['route']['paths'][0]['distance']
for s in steps: duration=duration+int(s['duration']) #caculate the time
for i in s['polyline'].split(';'): pts.append(str(order)+','+i) #get the point of route order+=1
output=open('od_result.txt','w') #load to saveoutput.write('order,x,y,d,time\n') #the header
for pt in pts: output.write(pt+',{0},{1}\n'.format(dis,duration)) #write your txt
将result.txt添加进来显示xy坐标，坐标是高德坐标系，加载高德地图在线底图
通过[点集转线工具]转为线要素，这样便得出步行路径
拾取坐标都没注意，还没到三圣乡的嘛
但是它是匹配高德地图的，下面天地图底图的话就偏了，需要纠偏转换坐标（蓝色线）
