I need to download google location history data in kml for a period of time.
Up until August 26, 2015, a URL in this format worked:
https://maps.google.com/locationhistory/b/0/kml?startTime=$start_seconds&endTime=$end_seconds
Now a link in that format fails.
I suspect the problem is related to google changing the way its website displays location history, though that change happened nearly a month earlier on July 22.
A commenter on the google products forum suggested this:
[T]he KML generation can do multiple days, so just edit the URL
Eg https://www.google.com/maps/timeline/kml?authuser=0&pb=!1m8!1m3!1i2015!2i7!3i1!2m3!1i2015!2i7!3i8 gives 7 days.
Highlighting the parts of the date: pb=!1m8!1m3!1i2015!2i7!3i8!2m3!1i2015!2i7!3i8
Note the month is zero based, so one off normal, 0=Jan, 11=Dec
The commenter is wrong that the above link gives seven days. It appears to only give about three, but perhaps the commenter is on the right track.
I have tried different values for the fields in the commenter's URL that are not obvious date-related but have not been able to find a URL that returns a kml file with data for more that a few days.
I have several maps that use location history data, they are now all broken.
Edit: There's a similar question here: Extfiltrating Google Location History from Timeline
Go to https://takeout.google.com/settings/takeout and select only "Location History" with "KML format". Click "Next" and, then, "Create archive". After a while it will let you download a zip file with your (presumably entire) location history in KML format.
I tried and was able to download more than one year of my locations: I probably opted in the Location History service a little more than one year ago...
Undocumented changes to stable Google geo products are why I've been moving my personal and work projects from Google to open source products like Leaflet.
I've also been trying to figure how to get old-school location history kmls, but I'm not having any luck. The kml header information reflects that you have asked it to download a longer period of time, but it only actually includes placemarks for a few days.
A short term workaround is to download this app: https://play.google.com/store/apps/details?id=com.homedev.locationhistory
It's able to download 1-7 days of history, which you can then export as a kml. I'm not sure if the devs have cracked the url formatting or if they just loop through the short timespan data several times to make it look like it is downloading a week at a time.
Looks like that the maximum date range is 5 days. If I request the bigger period it returns me kml without any coordinates. Is there any way to get the entire location history?
