为了使 GPX 针对 OrganicMaps 进行优化并处理一堆 Google 边缘情况(例如缺少星标位置的坐标和描述),我修改了 @DrGecko 的代码,如下所示:
#!/usr/bin/env python3
import argparse
import json
import re
import xml.etree.ElementTree as ET
from xml.dom import minidom
def ingestJson(geoJsonFilepath):
poiList = []
with open(geoJsonFilepath, encoding='utf-8') as fileObj:
data = json.load(fileObj)
gmQuery = re.compile("http://maps.google.com/\\?q=([-0-9.]+),([-0-9.]+)")
for f in data["features"]:
title = f["properties"].get("location", {}).get("name", '')
gmapsUrl = f["properties"].get("google_maps_url", '')
lon = f["geometry"]["coordinates"][0]
lat = f["geometry"]["coordinates"][1]
cmt = f["properties"].get("Comment", '')
link = f["properties"].get("google_maps_url", '')
# Fill in blanks for Organic Maps
if cmt == '':
cmt = '<a href="'+link+'">'+link+'</a>'
# Handle starred places without proper coordinates/comments
if lat == 0 and lon == 0:
if title == '':
title = "Starred Place"
matches = gmQuery.findall(gmapsUrl)
if len(matches) == 1 and len(matches[0]) == 2:
lat = matches[0][0] # Google order is backwards from GeoJSON
lon = matches[0][1]
else:
# We have basically no information, so at least provide OM the link
cmt = '<a href="'+link+'">'+link+'</a>'
poiList.append({'title': title,
'comment': cmt,
'date': f["properties"]["date"],
'lon': lon,
'lat': lat,
'link': link,
'address': f["properties"].get("location", {}).get("address", '')})
return poiList
def dumpGpx(gpxFilePath, poiList):
gpx = ET.Element("gpx", version="1.1", creator="", xmlns="http://www.topografix.com/GPX/1/1")
for poi in poiList:
wpt = ET.SubElement(gpx, "wpt", lat=str(poi["lat"]), lon=str(poi["lon"]))
ET.SubElement(wpt, "name").text = poi["title"]
ET.SubElement(wpt, "desc").text = poi["address"]
ET.SubElement(wpt, "cmt").text = poi["comment"]
ET.SubElement(wpt, "link").text = poi["link"]
ET.SubElement(wpt, "time").text = poi["date"]
ext = ET.SubElement(wpt, "extensions")
ET.SubElement(ext, "color").text = "0000ff"
xmlstr = minidom.parseString(ET.tostring(gpx)).toprettyxml(encoding="utf-8", indent=" ")
with open(gpxFilePath, "wb") as f:
f.write(xmlstr)
def main():
parser = argparse.ArgumentParser()
parser.add_argument('--inputGeoJsonFilepath', required=True)
parser.add_argument('--outputGpxFilepath', required=True)
args = parser.parse_args()
poiList = ingestJson(args.inputGeoJsonFilepath)
dumpGpx(args.outputGpxFilepath, poiList=poiList)
if __name__ == "__main__":
main()

最后我通过创建一个小的 python 脚本来在格式之间进行转换来解决这个问题。这可以很容易地适应特定需求:
#!/usr/bin/env python3
import argparse
import json
import xml.etree.ElementTree as ET
from xml.dom import minidom
def ingestJson(geoJsonFilepath):
poiList = []
with open(geoJsonFilepath) as fileObj:
data = json.load(fileObj)
for f in data["features"]:
poiList.append({'title': f["properties"]["Title"],
'lon': f["geometry"]["coordinates"][0],
'lat': f["geometry"]["coordinates"][1],
'link': f["properties"].get("Google Maps URL", ''),
'address': f["properties"]["Location"].get("Address", '')})
return poiList
def dumpGpx(gpxFilePath, poiList):
gpx = ET.Element("gpx", version="1.1", creator="", xmlns="http://www.topografix.com/GPX/1/1")
for poi in poiList:
wpt = ET.SubElement(gpx, "wpt", lat=str(poi["lat"]), lon=str(poi["lon"]))
ET.SubElement(wpt, "name").text = poi["title"]
ET.SubElement(wpt, "desc").text = poi["address"]
ET.SubElement(wpt, "link").text = poi["link"]
xmlstr = minidom.parseString(ET.tostring(gpx)).toprettyxml(encoding="utf-8", indent=" ")
with open(gpxFilePath, "wb") as f:
f.write(xmlstr)
def main():
parser = argparse.ArgumentParser()
parser.add_argument('--inputGeoJsonFilepath', required=True)
parser.add_argument('--outputGpxFilepath', required=True)
args = parser.parse_args()
poiList = ingestJson(args.inputGeoJsonFilepath)
dumpGpx(args.outputGpxFilepath, poiList=poiList)
if __name__ == "__main__":
main()
...
可以这样调用:
./convert-googlemaps-geojson-to-gpx.py \
--inputGeoJsonFilepath my-saved-locations.json \
--outputGpxFilepath my-saved-locations_converted.gpx
