[PYTHON] YOLP Get map information XML file with Yahoo! Static Map API
Overview
--Call YOLP Yahoo! Static Map API in Python to get map image and map information XML --YOLP If you specify xml in the output parameter of Yahoo! Static Map API, you can get the information about the map image to be acquired when output = xml is not in XML. --Operation check environment: macOS Catalina + Python 3.8.5
Program by Python
from urllib.request import Request, urlopen
import xml.dom.minidom as MD
appid = 'YOUR APPLICATION ID' #Specify application ID
headers = {'User-Agent': 'Yahoo AppID: {0}'.format(appid)}
# lat=Latitude of the center, lon=Longitude of the center, z=Scale level, output=Output format
#This time, specify the latitude and longitude of Nagoya Station
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'
#Download and save the map image
req = Request(png_url, headers=headers)
with urlopen(req) as res:
with open ('map.png', mode='wb') as file:
file.write(res.read())
#Output XML of map information
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:
#Format XML and output
dom = MD.parseString(body)
dom.writexml(file, addindent=' ', newl='\n', encoding='utf-8')
Output result
Map image
The acquired map image.
Map information XML
The meaning of the main elements and attributes.
--Coordinates: Map center coordinates --Coordinate-UL: Coordinates on the upper left of the map --Coordinate-UR: Coordinates on the upper right of the map --Coordinate-DL: Coordinates at the bottom left of the map --Coordinate-DR: Coordinates at the bottom right of the map --Image: Map size (unit: pixel) --Scales: List of scale values that can be displayed on the map in the center coordinates of the map --mode: Map type --Scale: Scale value --zlevel: Scale level --sc: Scale ID
The retrieved XML file.
