Copy it into a new map
This is really useful if someone has created a Google map and you want to use the points without adding them all manually, or you want to add more content while using an original map as a template.
GMaps Tips has the original guide: I’ve tried this in Internet Explorer and Firefox and it didn’t work, but it did work in Chrome.
When in your map, look for the link ‘View in Google Earth’. If you can see that, you can right-click the link and copy it. Then Click: My Maps > Start a new map > Edit > Import > Add by URL, then paste in the URL you just copied.
View other information alongside your map
So you’ve created a map of meeting places that your group likes to use. While you are viewing that map you’ll see that you can also search for other things on the map. Try it by entering ‘Schools’. You’ll see that a little pane appears in the bottom left corner and as you run more searches, you can choose whether to show or hide the search results.
In this example, I searched for libraries, which show alongside the points I created.
