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.
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.

You can now see New York City street views from the late 1800s and early 1900s as Google Earth street views. Take a virtual visit to the Big Apple as it was 100 years ago! Or travel back even further in time to an 1836 map of NYC conveniently overlaid on a modern Google Earth view. These are just two of the many ways to use Google Earth for genealogy—and for fun.
Vintage New York City Street Views on Google Earth
Over 80,000 original photos from the late 1800s and early 1900s have been mapped into Google Earth to provide what’s essentially a Google Street View map of old New York City!
As you can see from this overview map (below), the old photos are concentrated in the areas of Staten Island, Brooklyn, Queens and Lower and Upper Manhattan. Dots represents historic photos that have been overlaid on Google Earth’s modern map (satellite view is also available).
Old NYC
You can zoom in to click on individual dots, which will bring up one or more individual photos of certain neighborhoods or street fronts:
Select the photos that match up best with your family history interests, such as a shot of your family’s old store front or apartment building. Or choose images that represent the time period in which your relatives lived in the area, so you can get a flavor of what their neighborhood would have looked like. (Click here for some ideas about where to look for your family’s exact address during the late 1800s or early 1900s.)
According to this article at BusinessInsider.com, a developer Dan Vanderkam worked with the New York Public Library to plot all the photos onto Google Earth. (A hat-tip to Genealogy Gems listener and reader Jennifer, who sent me this article because she knows how much I love old maps and data visualization!)
Another Old NYC Street View: 1836 Map
While we’re on the subject, I also want to mention another cool tool for visualizing old NYC street views. At the Smithsonian.com, there’s a cool historic map overlay of an 1836 New York City map in Google Earth. Use the scrolling and zooming tools to explore the parts of NYC that were already settled–and to compare them to what’s there today. You can also swap views to see the 1836 map with just a little round window of the modern streets.
The accompanying article quotes famous map collector David Rumsey about the 1836 map, which is his. He describes how you can see that much of the topography of Manhattan has changed over the years—did you know Manhattan used to be hilly? And I love how he calls out artistic features on the old map, too.
Smithsonian NYC street view 1836
Unfortunately, the old map doesn’t show much in the way of residents’ property lines or buildings. But you can clearly see the street layouts and where the parks and hills were. Comparing these areas with Google Earth’s street view today can help you better understand what things looked like in a much older version of one of the world’s great cities.
Use Google Earth for Your Genealogy
There are so many ways to use Google Earth for genealogy! My free video class will get you started. After a quick tutorial on downloading and navigating Google Earth, see how to utilize its powerful tools to identify an old family photo, map out addresses that may have changed and even plot an old ancestral homestead.
Old maps are vitally important for genealogy because the characteristics of a location can change in many ways over time. Historic maps help us understand the world as it was at the time our ancestors lived.
Here is a short list of just a few of the things that may have changed:
Street addresses
roads
town names
county boundaries
waterways that may have been filled in or opened up
railway lines
In fact, the country itself where they lived may be a completely different country. For example, my German ancestors lived in Prussia in the 19th century. Today, that area is part of Poland. Therefore, all of the village names have been changed to Polish names.
The David Rumsey Map Collection is an excellent place to go to find maps of your ancestors homeland for free.
Watch the Map Search Video
I’m going to explain the 7 steps to finding the maps you need for your genealogy research at this wonderful website! I highly recommend that you watch the short video below to see it in action as you read. The player will stay with you as you scroll down the page.
Step 1: Go to the David Rumsey Map Collection Website
The first thing you need to do is go to the David Rumsey website here. You’ll be greeted on the home page with glorious historic maps. (Stay focused because it’s easy to get distracted by all the fascinating maps!)
Scroll down on the David Rumsey website home page.
Step 2: Scroll Down to the Bottom of the David Rumsey Home Page
While you can search for a place name in the search box at the top of the page, there’s a better way to search. Scroll down the page until you get to Featured App: MapRank Search (it’s almost at the bottom.)
Step 3: Launch Map Rank Search
The Featured App – MapRank Search is the best place to search the website, but it’s easy to miss because it’s not at the top. So go ahead and click the Launch MapRank button in the upper corner of this section.
In the Featured App: MaprRank Search section click the Launch MapRank button
When you click the button it will open a new tab in your web browser which will take you to the Geographical Searching with MapRank Search page.
Quick Tip: The Fastest Way to MapRank Search
You can get there faster by going directly to https://rumsey.mapranksearch.com. I didn’t take you straight there from the beginning because I think it’s important to be aware of the home page and everything else it offers. However, today our focus is conducting the optimal search for old maps for you family history.
Step 4 Selecting the Map Time Frame
Here’s what the search page looks like.
The DavidRumsey.com search page
There are two very important features on this app page that will help you get the best results possible: the time slider and the location search box.
The time slider is located beneath the map:
Time Slider for searching maps by time frame
It’s important to first select the time frame that you are searching because that will dictate the results you get when you search on the location name. (We’ll get to that in just a moment.)
There is a slider on each end of the timeline. Slide them to specify the desired time frame. In my example below, I’m looking for maps between 1800 and 1900.
Searching for maps between 1800 and 1900
As you move the sliders, you’ll notice that the maps in the right hand column will change. This is because only maps that fall within the range you select will be offered in the Instant Search Results column. But before we look at those, we need to type in a location in the next step.
Step 5: Selecting the Location
With your time frame selected, now you’re ready to type the location in the search box.
As you type, the app will make suggestions. But wait! Before you click the Find a Place button to run the search, look carefully at the list of suggested locations that may appear. Many locations names can be found in different areas. That is certainly the case with the name of the tiny village where my great grandfather was born: Kotten.
Type the location name to search the maps
In fact, the list doesn’t even include the Kotten I am looking for.
In cases like this, it is best to search a little more broadly. When Kotten was part of Prussia, it was located in Kreis Johannisburg so I could try searching for that. Even better might be to search for the largest city in the area since Kotten was such a tiny village. Arys was the largest city in the area.
Once you type in the name (and select from the suggestions if needed) click the Find a Place button just to the right of the search box.
Step 6: Analyze the Map Results
In my example of searching for the city of Arys (which is the name it was known by in the 19th century when it was part of East Prussia) the modern-day map displayed is actually Poland.
My search resulted in a map showing Orzysz, Poland
However, the David Rumsey website does a good job of cross-referencing the older German names (Arys) with the new Polish names (Orzysz). This is another reason why searching for a larger city works well. Larger cities are more likely to be in the David Rumsey system for cross-referencing, and of course they are easier to spot on the map. Generally speaking, the location you searched will be in the center of the display map.
Quick Tip: Verifying Location Names
Another quick way to cross-reference location names (or verify your findings in David Rumsey) is by searching for the name in Google Earth. In the example below, I typed in the Prussian city of Arys. Google Earth will offer options if more than one matching result exists.
I was a bit surprised to see “Arys” as one of the three listed results since it is not called that today. When I clicked Arys it took me to the city of Arys in the Turkistan Region of Kazakhstan, far away from Poland! Clicking Orzysz in the results list took me to the area of Poland that was once East Prussia. This confirms the results I received at the David Rumsey website.
Now it’s time to review the map results listed in the Instant Search Results column on the right. Isn’t it fantastic that David Rumsey’s website not only presented me with the correct Polish location, but also maps published between 1800 and 1900 that include Arys? I think so!
Map results appear in the column on the right side of the page.
Click the map you think best suits your needs. The map will open in in a new tab in your web browser. (These browsers tabs provide a nice bread crumb trail for your searching activities.)
All of the source information about the historic map that you chose will appear in the column on the left. (See the image in Step 7.) If you decide to use this map you’ll definitely want to accurately cite the source. Learn more about the importance of source citations here.
Step 7: Export the Map
I was delighted to find the village of Kotten on this map of Arys published by Reichsamt fur Landesaufnahme in 1893!
When you find a map that you would like to use for your family history research, export it to your computer. To do this, click Export in the upper right corner of the map and select the desired size. You can select a size ranging from Small Thumbnail to Extra Extra Large. Keep in mind that the larger the size, the more clarity you will have as you zoom in closer and closer. This is very important if you plan on using the map in an overlay in Google Earth. You can learn how to create your own map overlays in my video tutorial series on using Google Earth for genealogy available here, and in my book The Genealogist’s Google Toolbox.
Click “Export” to save the map to your computer.
Be patient while downloading to your computer because it can take several moments to export a large map. The saved file will probably be zipped. To unzip it, on a PC right-click and select ExtractAll from the pop-up menu. This creates an open version of the folder containing the map.

Thom learned how to use Google Earth for family history after watching my free Google Earth for Genealogy video, and then made a landmark discovery: his ancestors’ pond, business and a photo of his family at work.
This Using Google Earth for Family History success story was recently sent in by Thom, a young genealogist who blogs at The Millennial Genealogist. Be sure to click on the picture that goes with his story–it’s really neat.
Thom’s Google Earth Story
“I am writing to share with you a TOTAL (and entirely unexpected) success in using Google tools for my research.
By way of introduction, I am a young genealogist (age 21) from Massachusetts. I recently discovered your podcast and have been working through the archived episodes on my daily 1.5 hour commute.
I watched your Google Earth presentation last weekend, and had some time to try your tips out after work today.
My curiosity having been piqued, I began exploring the map. I know that two sets of my second-great-grandparents, Bert Barrett and Grace Freeman, and James Adams and Elizabeth Todd, all lived near Oldtown Church (presently the First Congregational Church). I zoomed in:
Looking at Google’s current street names, Oldtown Church is right by the intersection of Mt. Hope and Old Post (you’ll note the small cross). Now keep following Mt. Hope Street – do you see what I see? Todd’s Pond! I just knew this couldn’t be a coincidence. So I went straight to Google again:
And the very first result, a page within a Google Book on the history of North Attleboro, was astonishing:
“In the days before electric refrigeration, North Attleborough’s homes and stores relied upon ice harvested from either Whiting’s Pond or Todd’s Pond (depicted here).
By the time this 1906 photograph was taken, farmers George, Henry, James, and William Todd found selling ice more profitable than farming and founded the Oldham Ice Co.
Todd’s Pond was located on the westerly side of Old Post Road near the corner of Allen Avenue. The Oldtown Church is visible in the background.”
Mentioned by name are great-great-grandmother Elizabeth’s four brothers, George, Henry, James, and William Todd. What a spectacular find!
I plan to reach out to the local museum that prepared the book to see if they can provide a better copy, and even additional media should I be so fortunate.
In short, I wanted to take a moment to say THANK YOU so very much! Had I not been exploring Google Earth at your suggestion, I’m not sure if I ever would have ever noticed “Todd’s Pond.”
The Power of Google Used for Genealogy
I hope you are using Google Earth for family history! Paired with Google Books and the rest of rest of Google’s genealogy tool box, it can help you unearth fascinating facts about your family history.
Here’s an image I found (using Google Images) that shows the process of harvesting ice, a profession long gone with the age of modern refrigeration.
The ice trade around New York; from top: ice houses on the Hudson River; ice barges being towed to New York; barges being unloaded; ocean steamship being supplied; ice being weighed; small customers being sold ice; the “uptown trade” to wealthier customers; an ice cellar being filled; by F. Ray, Harper’s Weekly, 30 August 1884. Public domain image, Wikimedia Commons. Click to view.

Ten years ago in June, Google Earth was born. The world put it right to work. Within months, recalls a Google Earth employee, “Hurricane Katrina showed us how useful mapping tools like Earth could be for crisis response efforts. Rescue workers compared before and after Satellite imagery in Google Earth to better locate where people were stranded.”
“In the years after,” the blog post continues, “with more than 2 billion downloads by people in nearly every country in the world, Earth has enabled people to discover new coral reefs, journey to the Moon and into deep space, find long-lost parents, clear landmines and much more.”
