ubuntu20.4搭建本地地图服务（本地OSRM）

1. 下载地图数据文件（xxx.osm.pbf），下载网址http://download.geofabrik.de/，例如下载Asia下的China的文件（China.osm.pbf），并放到对应的安装路径/home/user/Desktop/China_osm(记住这个路径)。

2. 确保ubuntu已经成功安装docker，如果还未安装可以参考https://blog.youkuaiyun.com/qq_53258482/article/details/129215605?spm=1001.2014.3001.5501。

3. 使用命令进行搭建

cd /home/user/Desktop/China_osm

sudo docker run -t -v $(pwd):/data osrm/osrm-backend osrm-extract -p /opt/car.lua /data/China.osm.pbf

sudo docker run -t -v $(pwd):/data osrm/osrm-backend osrm-partition /data/China.osrm

sudo docker run -t -v $(pwd):/data osrm/osrm-backend osrm-customize /data/China.osrm

sudo docker run -t -i -p 5000:5000 -v $(pwd):/data osrm/osrm-backend osrm-routed --algorithm mld /data/China.osrm

4. 使用web端查看

docker run -p 9966:9966 osrm/osrm-frontend

5. python 在本地调用OSRM进行路网距离请求

import os

import requests

OSRM_HOSTPORT = os.getenv("OSRM_HOSTPORT", "localhost:5000")

def calDisOSRM(ori, dst):

url = """http://{hostport}/route/v1/driving/{lon0},{lat0};{lon1},{lat1}?overview=full""".format(

hostport=OSRM_HOSTPORT,

lon0=ori[1],

lat0=ori[0],

lon1=dst[1],

lat1=dst[0]

)

while True:

try:

responses = requests.get(url).json()

print(responses)

break

except Exception:

print("error")

route = responses["routes"][0] # Getting the next route available

tripdistance = route["distance"]

#print("Dist: ", tripdistance)

return tripdistance

ori = [30.68435,104.34834]

dst = [30.67,104.0578]

dist = calDisOSRM(ori, dst)

print("dist:",dist)
