How to Export Google MyMaps to KMZ for Google Earth
Show Notes: If you’ve created a MyMap in Google Maps, there’s a lot more that you can do with it if you import it into Google Earth. However, exporting it out of MyMaps as a KMZ that can be used in Google Earth isn’t really obvious. The good news is that it’s not hard to do. I’ll explain how and I’ll also show you how to import the KMZ file into Google Earth.

How to Export a MyMaps Project File
If you have several items in your MyMaps project, make sure that each item that you want to be included in the file that you’re exporting has a checkmark next to it. Whatever is checked is activated on the map display and will be included in your exported file.
Next, in the upper left corner of Google MyMaps, you’ll see three vertically stacked dots. When we click that, you’ll get a menu that includes Download KML. KML and KMZ are file extensions that are supported by Google Earth.
You’ll also see View Map in Google Earth in this menu. If you click that the MyMaps project will open in a new web browser tab in the web version of Google Earth. You don’t want that because the web version does not have all the features that are available in the free downloadable software version of Google Earth.
Click to select Download KML. KML stands for Keyhole Markup Language. This is a geographic file. The difference between KML and KMZ is that KML is typically a single item while a KMZ is a zipped file potentially containing several items. Each placemark and data item added to your project is a single item. When you have several like in our example project, you will want to export it as a KMZ. So even though the menu says Download KML, go ahead and click it.
When you click it you’ll get a pop-up menu with two options:
- Keep data up to date with network link KML (only usable online).
This will include all your data. If any of that data is coming from another source on the cloud and that source updates, your data will update in Google Earth. - Export as KML instead of KMZ. Does not support all icons.
This can zip your project as a .KMZ but it might not transfer all your icons, particularly those that might be coming from another source on the cloud.
In many cases, either of these would be fine. But when in doubt, I select Keep data up to date with network link KML so that all my project data will remain current.
After you make your selection, your file will be exported to your hard drive. You can select the destination where you want it saved. It will be a KMZ file because there are multiple items that have been zipped into one package.
How to Open an Exported MyMaps KMZ File
On a PC you will see the downloaded KMZ file in the bar at the bottom of your screen. If you click the up arrow you can open the location on your hard drive where the file was saved. You can also click Open. That opens the KMZ in a program that can read it like Google Earth if it’s already installed on your computer. The easiest way to open the file is to simply double-click it. Your computer will automatically detect that you are opening a KMZ file and it will automatically launch your Google Earth software, and open and display the file in it. It may take a few extra moments to load and run because it’s trying to do two things at once, and Google Earth is a pretty robust program.
There are three panels in Google Earth:
- Search (where you enter names, addresses and more to fly to locations in Google Earth),
- Places (your Google Earth files and folders These are private and are not published by Google.)
- and Layers (data that can be streamed from cloud sources.)
Your project file will be in the Temporary Folder of the Places Panel. Google places opened files in the Temporary folder because it doesn’t know whether you just want to look at it one time, or you want to keep it. When you want to keep a file, you will need to drag and drop it onto MyPlaces at the top of the Places panel, or into a folder you have created.
Also, Google Earth doesn’t autosave. So it’s important to save your work before you close the program. Otherwise, your file will be lost. To save your file, in the menu at the top of the screen select File > Save > Save MyPlaces.
How to Display a MyMaps File in Google Earth
There is a small arrow next to your project file in the Places panel that indicates it is a nested project folder. Click the arrow to display the contents of this zipped container. Inside is the actual MyMaps project folder or the project. Continue to click arrows to reveal the nested content. Now that you can see the individual items, you can now work with them.
To display the entire project on the screen, double-click the main project file (not one of the nested items). Click only to highlight it. Don’t click the linked title because that will only display the descriptive text you included in your original MyMaps project.
Everything that you saw in MyMaps is now in Google Earth. You can check and uncheck items within the project in the Places panel depending on what you want to be displayed on the screen.
How to Add Content to a MyMaps File in Google Earth
You can easily add additional content to your project. Click to select the project, then add content such as a Placemark. If you selected the Keep data up to date with network link KML option when you exported your file, you won’t be able to add items to the existing folders that came over from MyMaps. However, you can add individual items or new folders by selecting the top-level project.
The beauty of working with the project file in Google Earth is that you can now add content from the Layers panel, some of which was not available to you in MyMaps. You can also add additional items from the Toolbar at the top of the Google Earth screen.

Using Google Earth to Research Your Ancestors’ Neighborhood
Elevenses with Lisa Episode 22 Video and Show Notes
Live show air date: August 20, 2020
Join me for Elevenses with Lisa, the online video series where we take a break, visit and learn about genealogy and family history.
Please note: As is often the case with technology, sometimes things just don’t work like you think they will. As it turns out, items displayed clearly on my computer in Google Earth were not displaying in the live stream or captured on the video. Don’t worry, if you ever want to create a digital movie of your Google Earth maps, Google Earth has a video recording feature built in so this won’t happen. However, I did everything in this episode live and in real-time through live stream which apparently was at the root of the problem. Keep reading, because I have all the notes for you on what we covered, as well as screen shot images of everything that did not appear on the screen in the video!
Using Google Earth to Capture Your Ancestors’ Neighborhood
It’s a beautiful day in the neighborhood, and we are going to have some fun exploring one of my ancestors’ neighborhoods. Along the way I think you’ll pick up some interesting ideas on how you can explore your ancestors’ lives in a deeper way by getting to know their neighbors.
While you may not find it worthwhile to create a project like this for every family in your family tree, it could prove very helpful for:
- writing a story
- writing a family history blog post or article
- writing a book
- creating a family history story video
- teaching kids about the family history
- satisfying your curiosity!
We see our ancestors’ neighborhoods when we review census records. But have you ever wondered what was life really like in their neighborhood? This project can answer questions such as:
- Did they live close together?
- Did they share the same backgrounds?
- Did any of them work together?
- Did they have things in common?
- Were there a lot of children on the street?
The Google Earth Neighborhood Project
The genealogy project I’m creating in Google Earth in this video is the neighborhood of my great grandparents who lived in San Francisco from 1900-1912. Now, don’t be discouraged if your ancestors were farmers. Remember, everyone has neighbors and a community. Every community has records.
All the techniques covered in this video are covered in detail in my book The Genealogist’s Google Toolbox available here.
Available in the Genealogy Gems Store
The family: Charles Allen & Ellen Burkette
The Census: The 1910 U.S. Federal Census tells us that they lived at 288 Connecticut Street, San Francisco, CA.
Most of their close neighbors, don’t appear on the same page with them. Instead, the neighbors of Connecticut Street appear on the previous page. Always look at the pages before and after the page where you find your ancestor. Often you will find other relatives, close friends, and other people with connections to your family.
For this project we will need the free Google Earth Pro software. Although Google Earth is available in a Web version and an app, these do not include all of the same tools. I always use the software. If you already have Google Earth, check to see if you have the most recent version.
You will also need an a good internet connection to operate Google Earth.
Follow along with the video with the notes below.
Rumsey Historical Maps
In the Layers panel, turn on Rumsey Historical Maps in the Gallery by clicking to check the box. Gold medallion icons will appear on the map. Hover your mouse over the icons to see the title and date. Click the select a map. In the pop-up box, click the thumbnail image of the historic map to automatically overlay it.
The map will be listed in the Temporary Places at the bottom of the Places panel. You can click drag and drop it to any location within the Places panel.
Videos in Placemarks
Videos before and after the great earthquake of 1906 (See Images) Add videos from YouTube to placemarks by copying the Share embed code and pasting it into the Description area of the placemark.

Map Overlays
Click the box to activate items like the custom map overlay I created using the 1905 Sanborn Fire Insurance Map of Connecticut Street.
Search for Addresses
Search for addresses like 288 Connecticut, San Francisco in the search box in the upper right corner of Google Earth.
Add Placemarks in Google Earth
Set a placemark for a home by clicking the Placemark icon (yellow pushpin) in the toolbar the top of the screen.
Use Street View to Get a Closer Look
Visit the street up close and person with Street View. Click on the Street View icon in the upper right corner, drag it over to the map, and drop it on the blue line.
Add Photos to Placemarks
Photos can be embedded into placemarks, such as the photo of my Grandpa and his father (See Image)
Photo of my grandather being held by his father displayed in a Google Earth placemark.
and the photo of my Great Grandfather next to his streetcar. (See Image)
Click the placemark to display the photo.
If you add images from your computer, they will only appear when the map is viewed in Google Earth on your computer. If you host the image in cloud on a photo sharing site or your own website, you will be able to share your map file with other people and they will be able to view the images.
Plot Where Your Ancestors Lived Using Placemarks
Search for each family address and mark the locations with placemarks.
3D Models in Google Earth
3D models (like the streetcar I showed) are created by other Google Earth users and are available online. The HTML code is pasted into a placemark. (You can learn more about this in episode 13 of my Google Earth for Genealogy video tutorial series.
Search for Neighbors
Search for the addresses of neighbors you find in the census and other records.

In this case I searched for the address I found for Bertin & Lenora Hall (293 Connecticut.) Bertin was a locomotive engineer, born in the United State, and they were renting their home.)
Add a Folder to the Google Earth Places Panel
You can add folders to help keep your items organized in the Places panel by right-clicking on MyPlaces, and selecting Add > New Folder. Name the folder as desired, and then drag and drop it to the desired location in the Places
Use Historical Maps from a Variety of Years
Comparing the locations with maps from various years helps you see the evolution of the neighborhood. Notice that some maps don’t line up exactly with the modern map. This is due to inaccuracies often found in old maps.
Add Country of Origin Icons
We can learn more about the makeup of the neighborhood by designating their country of origin. Some neighborhoods may be predominately filled with many people from the same country or even village. Others, like my Great Grandfather’s neighborhood, were quite diverse:
Burkett – U.S.
Hall – U.S.
Dunne – Ireland
Becker – German
Harrington – England
Crawford – Scotland
McTiernan – Irish
Rutherford – Canada
Geib – Germany
Customize Placemark Icons
Add custom icon images to represent the family’s country of origin. Images around 40 px x 40 px work well. (Premium Members click here to download the icons I used.)
Customizing the placemark icon in Google Earth
The Google Earth Opacity Slider
Use the Opacity slider to make a map overlay being displayed more transparent. Start by clicking the space just below the map in the Places panel in order to select it. Then click the Opacity button at the bottom of the Places Slide the slider to change the transparency.
Add Details to the Placemark Description
I typed information into the Description area of my placemarks such as their occupation, fully street address and country of origin. Typically the first two lines of text will be visible in the Places Click the placemark to open and read or add all of the information desired.
Researching and Recording Occupations
Explore old maps, city directories, county histories and other resources to locate possible places of employment. You can then mark each location with a placemark. I used the “wrench” icon to represent work.
Search for Locations
Where did David Rutherford work? I searched for “Cannery San Francisco” and sure enough Google Earth found a site in the northern part of the city.
The Neighborhood School
Let’s not forget the children – I marked the school attended by my grandfather and a photo of him with his classmates. (See Image Below)
My grandpa and his school mates c. 1911.
The Future of the Neighborhood
The neighborhood continued to grow well after they left as revealed by another David Rumsey historic map from 1938 found in the Layers Panel > Gallery.
