If you want to create a KML file of your Google Maps, do this:
- Go to your map
- Right click on the hyperlink “View in Google Earth”
- Select “Copy Link Location” from the menu
- Open a new tab in your browser and paste the link into your address bar
- Before pressing the ENTER key, change part of the URL from “Output=nl” to “Output=kml” and leave everything else the same and press ENTER
- Save the file.
At a minimum, this makes a good backup file for your map. But better still, you can edit it in a text editor and import it later. Google Maps is great and very usable, but sometimes only a text editor (or some custom code) can change the file the way you want.
Have fun!
P.S. I learned this from another page, but I lost the link! Thanks to whomever blogged about this before. Great tip!
