YOLP Yahoo!スタティックマップAPI で地図情報 XML ファイルを取得する

Posted at

概要

  • Python で YOLP Yahoo!スタティックマップAPI をコールして地図画像と地図情報XMLを取得する
  • YOLP Yahoo!スタティックマップAPI の output パラメータに xml を指定すると、output=xml ではないときに取得する地図画像についての情報を XML で取得できる
  • 動作確認環境: macOS Catalina + Python 3.8.5

Python によるプログラム

from urllib.request import Request, urlopen
import xml.dom.minidom as MD

appid = 'YOUR APPLICATION ID' # アプリケーションIDを指定
headers = {'User-Agent': 'Yahoo AppID: {0}'.format(appid)}

# lat=中心の緯度, lon=中心の経度, z=縮尺レベル, output=出力形式
# 今回は名古屋駅の緯度・経度を指定
png_url = 'https://map.yahooapis.jp/map/V1/static?lat=35.170476&lon=136.882250&z=17'
xml_url = 'https://map.yahooapis.jp/map/V1/static?lat=35.170476&lon=136.882250&z=17&output=xml'

# 地図の画像をダウンロードして保存
req = Request(png_url, headers=headers)
with urlopen(req) as res:
  with open ('map.png', mode='wb') as file:
    file.write(res.read())

# 地図情報のXMLを出力
req = Request(xml_url, headers=headers)
with urlopen(req) as res:
  body = res.read().decode('utf-8')
  with open ('map.xml', mode='w') as file:
    # XML を整形して出力
    dom = MD.parseString(body)
    dom.writexml(file, addindent='  ', newl='\n', encoding='utf-8')

出力結果

地図画像

取得した地図画像。
