Creating Image Overlays in Google Earth Desktop
Tutorial Contents
Prerequisites
Download full-text PDF. Historical maps of Ljubljana for GIS applications. Digitization, description, georeferencing (cartography) and geolocation (photography), tiling and web publication.
- Absolutely no programming skills needed!
- In April 2017, Google Earth on Web was released, which puts Earth on the browser. However, for this tutorial, you will need Earth for Desktop installed on your computer. Download the latest version here. (It's free!)
Let's Get Started!
Open Google Earth.
Zoom to the area where you want to overlay your map. For this example, search for 'Glacier National Park, USA'. Google Earth will automatically zoom you into the Glacier National Park area.
You can optionally turn on the Parks/ Recreation Areas layer, which may help you find Glacier National Park. To do this, go the Layers panel on the left-hand side of Google Earth, expand the folder More, and then check the box next to Parks/Recreation Areas.
Find the tools toolbar and the Add menu.
Now, let's add overlays!
Add an Image Overlay
Click the Add Image Overlay button to add a new image overlay. A New Image Overlay dialog box appears, and a green outline is placed on the Earth.
In the New Image Overlay dialog box, type in a name for the image overlay in the Name field. In this example, we typed 'Glacier National Park Map'.

Copy and paste the link below into the Link field, or click 'Browse..' and find an image to add from your local hard drive. In this example, we will use the following URL from the Internet:
http://upload.wikimedia.org/wikipedia/commons/3/31/Map_of_Glacier_National_Park.jpgMove the Transparency slider to the left to make the image a little transparent, which will assist you in placing the image in the correct location. Use the park boundaries to help you align the park boundaries on the map with the boundaries in Google Earth.
Use the center crosshair marker to move the image overlay on the globe and position it in the right location.
Use the triangle marker at the left to rotate the image for better placement.
Use any of the corner or side anchors to stretch or skew the selected corner or side. If you press the Shift key when selecting this marker, the image is scaled from the center.
Click OK when you are finished. The map is now listed in the Places panel, and can be saved to a KML file with other Google Earth project data you have created.

When you want to leap backwards in time and see how your backyard changed…
Where can you view historical imagery in an intuitive, user-friendly map viewer?
Look no further because here are 5 online platforms to journey into the past…
And explore historical imagery for nearly anywhere on Earth.
1 Google Earth Pro
Not only is Google a world leader in geocoded addressing, but you can leap to the past with its historical time slider.
From satellite to aerial photography, Google Earth Pro puts the whole world in your hands.
First, zoom to your area of interest. Click the time slider icon. Now, visit your neighborhood in the past. You’ll know which years are available based on the thumbnails.
2 Esri’s Wayback Living Atlas
Recently, Esri has released their newest addition to the Living Atlas of the World. Basically, this collection of Earth curates essential geographic information that impacts people’s daily lives.
For example, this includes items such as weather, traffic, elevation, demographics, oceans and urban systems.
As part of their enormous collection of maps, Esri’s Wayback Living Atlas lets users browse historical imagery back in time.
Still in the introductory phase, their collection of imagery is growing and evolving into a must-have platform for map historians.
3 USGS LandLook
If you want to dig into USGS’s giant collection of about 7 million scanned historical image, take a trip to the USGS Earth Explorer. We have a step-by-step tutorial how to download imagery from the USGS Earth Explorer. Instead of satellite imagery, your search criteria would be “Aerial Imagery”. Some of my favorites being NAIP, DOQ and the mosaics.
For rapid viewing of Sentinel-2 and Landsat imagery, the USGS Land Look spans back to 1999.
- First, load your images by filtering the days, years, cloud cover and sensors.
- Next, you can play a video displaying each scene in your time span.
- Finally, if you want to export your scenes as PNG, GeoTIFF or JPG, you can select the “export” tool.
Overall, USGS Land Look is ideal for searching historical imagery which are part of the Sentinel-2 and Landsat archive.
4 NASA Worldview
NASA’s Worldview has 600 global, full-resolution satellite imagery layers.
Albeit, they’re coarser than the others in this list. But essentially, they show the entire Earth as it looks “right now”. Actually, it’s updated within three hours of observation.
So you’re probably asking: this isn’t historical imagery, is it?
Instead of using the current date (which is the default), you can step back in time by adjusting the time slider. Unlike the cloudless imagery were accustomed to, this is the true view of our planet.
5 Planet Labs
Here’s a couple cool facts about Planet:
- They are a team of ex-NASA scientists who built their business embracing low cost, lightweight, micro satellites in space.
- They are the largest collector of Earth imagery with a constellation of 175+ satellites in orbit at this time.
- Planet has a “freemium” service which dates back to 2009 giving you historical context on your areas of interest.
Planet’s fleet of satellites is ideal for monitoring anything on Earth. For example, Planet Stories allows users to use space imagery and tell their own story anywhere.
Aerial Orthoimagery for Historical Context
When you want historical context for an area of interest, there are several options to help you get started.
Google Earth is a mobile and desktop application with an enormous collection of historical imagery for free.
Esri’s Wayback Living Atlas provides an online platform. It’s free and it’s growing for historical images. Lastly, it’s becoming more ubiquitous to the average user.
Finally, USGS, NASA and Planet’s constellation of satellites provide an alternative means to view the history of Earth.
