google mapskml
I know that in Google My Maps, I can click the folder icon and select Export to KML to download a KML file.
However, is it possible that, given the URL of someone's My Map, I can go in and get the KML out of it? I've read an answer that you can add the output=kml querystring to a URL, but that looks like something that used to work in old maps, but is no longer supported.
So, is there any way to currently do this with the current version of Google Maps?
Per this Google Calendar help link there is at least a way to link a map location to an event, though it is not exactly what you want to do, it's close.
When you fill in the "Where" field on the "Create Event" page, Google Calendar will create a link to a Google Map search result. To ensure an accurate result, please enter a full address, including city and state.
Note: The "map" link won't appear until you save the event.
I tested this and it works -- you must enter a mappable address in the location field, then after you save the map, a map link will appear on the event:
Click on "Powered by Google" logo which is located on the lower left corner of that map. It will take you to the original Google map.
