This is an introductory user guide for students, educators, and anyone else who would like to learn to use Google Earth Pro for education or fun. It includes instructions and diagrams on how to perform common tasks associated with viewing or creating map data. It also provides links to other sites that offer additional information.

Google Earth is a geobrowser that offers satellite and aerial imagery, ocean bathymetry, and other geographic data over the internet to represent the Earth as a three-dimensional globe. Geobrowsers are also known as virtual globes or Earth browsers. Google Earth provides search capabilities and the ability to pan, zoom, rotate, and tilt the view of the Earth. It also offers tools for creating new data and a growing set of layers of data, such as volcanoes and terrain, that can be displayed in the 3D Viewer. Google Earth Pro and other versions are available for free on the Google Earth Versions web page.

Below are presented techniques for performing essential functions in Google Earth Pro. More information is available at Google Earth Help Community.

For a one-page summary of some of these essential functions, see the Google Earth Pro - Tip Sheet (Acrobat (PDF) 5.5MB Aug1 18).

Essential Google Earth Pro Functions

The Google Earth Pro User Interface

When you launch Google Earth, the Earth appears in the 3D viewer within the Google Earth user interface, which also includes a set of panes, a menu, a toolbar, navigation controls, and a status bar. The 3D viewer shows you aerial and satellite imagery and information about places represented on the map as points, segmented lines, polygons, image overlays, photographs, and 3D models. When the terrain layer is activated, the landscape appears in three-dimensional relief.

The Google Earth Pro Toolbar

The Google Earth toolbar contains tools that perform tasks related to the configuration of the user interface, the creation of objects to place on the map in the 3D Viewer, recording a tour, showing historical imagery, showing sunlight in the 3D Viewer, a ruler for measuring lengths of lines and paths, emailing a representation of the 3D Viewer, saving or printing an image of the contents of the 3D Viewer, and viewing the data in Google Maps.


The Google Earth Toolbar offers tooltips that pop up to identify each tool as the mouse passes over it. For example, the Hide/Show Sidebar button toggles the visibility of the three panes on the left side of the user interface on and off. The Add Placemark, Add Polygon, Add Path, and Add Image Overlay buttons are for creating new data. The functions of some of these tools are described below.


Navigation is the process of changing the position of your view of the Earth. The position of the view can be changed through the navigation controls, mouse navigation, key combinations, searching, or visiting pre-defined places.

The navigation controls are used to adjust the location of the view, the map orientation, the zoom level, and the tilt.

Drag the ring with the "N" on it to rotate the view. Click the "N" to orient the globe so that north is at the top.

Dragging the mouse while the left or right button is held down can also be used to navigate. To use the mouse to pan the 3D Viewer, hold down the left mouse button and drag the view in the direction that you would like to move it. With the right mouse button held down, you can rotate the 3D Viewer clockwise by dragging the mouse to the left, and you can rotate it counterclockwise by dragging the mouse to the right. The mouse wheel can be used to navigate as well. To zoom in with the mouse, turn the mouse wheel away from you. To zoom out with the mouse, turn the mouse wheel down toward you. With the right mouse button held down, you can also zoom in by moving the mouse down, and zoom out by moving it up.

The Google Earth Pro Status Bar

Google Earth Pro Places Pane - update

The Google Earth Status Bar shows the imagery date, latitude, longitude, elevation, and eye altitude of the current view. It is visible at the bottom of the Google Earth User Interface when the Tour Guide is closed.


In the Search pane, your can use the three tabs, respectively, to:
  • Search for places
  • Get directions
  • Show a list of recent searches
  • Get directions
  • Copy search results to the Google Earth My Places folder
  • Copy search results to the clipboard as KML
  • Print search results

As the Search pane is pictured here, we have flown to Yosemite National Park, after clicking the Search button.

Addresses can be specified in a variety of formats. For example, you can fly to 37.42197, -122.08414. In addition to natural features, you can search for cities, towns, countries, types of businesses, or other types of establishments such as schools, airports, churches, temples, mosques, hospitals, or police stations.

The Get Directions button will get you driving directions between two places that you specify. The resulting directions can be saved or played as a tour.

Working with Places

The Places pane is where third-party data and your own data are listed and organized. Data that has been loaded or created during the current session generally resides in the Temporary Places folder. Documents, folders, and placemarkers can be dragged to reorganize them in the Places pane.

The Google Earth Community and other web sites listed below are good sources of this data. However, in many cases, you may sometimes discover that there is insufficient data for a topic that you would like to cover in an educational setting. One remedy is to download the data that exists for that topic and add additional data to it. In some cases, it may be necessary to start from scratch. But in either situation, it is likely that you will need to:

A great deal of third-party data is available on the web. Good Places to Get Data gives a variety off sources for Earth science data. However, in some cases, you may sometimes discover that there is insufficient data for a topic that you would like to cover in an educational setting. One remedy is to download the data that exists for that topic and add additional data to it. In some cases, it may be necessary to start from scratch. But in either situation, it is likely that you will need to:
  • Create placemarks to identify particular points on the map, and possibly include descriptive information, images, and hyperlinks that appear in an information balloon when the placemark is clicked. For example, a series on rock outcrops can be identified by placemarks, with descriptions and closeup photographs placed in the information balloons.
  • Draw paths to identify routes or other linear features. This might be useful for a virtual guided tour along a trail.
  • Draw polygons to identify or outline areas or features of interest. Polygons might be used to enclose areas of similar soil type or vegetation.
  • Overlay maps or specialized aerial imagery on the Google Earth imagery. For example, a USGS topographic map overlay may help interpret a glacial landscape or a series of waterfalls.

Data that you download or create can be saved within the My Places folder so that it is available in subsequent sessions. You can either drag it into that folder or click Yes, when asked whether to save the items that are in the Temporary Places folder in the My Places folder when you exit Google Earth. However, it is a good practice to explicitly save your data. To save an item that is listed in the Places Pane, right-click it (ctrl-click on the Mac) and choose Save Place As from the contextual menu that appears. In order to make informed decisions about how to save your data, you need to know something about the format of Google Earth data.

Google Earth data, including placemarks, paths, polygons, and overlays, consists of KML (Keyhole Markup Language) markup that can be saved in text format with a .kml file extension, or, most commonly, in compressed KMZ format with a .kmz file extension. A KMZ file is actually a zip archive which contains a doc.kml file with KML code, and possibly other supporting files such as images. The KMZ markup for a place or a container can be viewed by right-clicking it (ctrl-click on the Mac), choosing Copy, and pasting it into a text editor.

Google Earth can open or import a variety of data files, including the standard KMZ and KML formats, as well as images (jpg, bmp, tif, tga, png, jpeg, gif, tiff, ppm, and pgm), gps (gpx and loc), and Collada models (dae). Google Earth Pro can also open ESRI shapefiles (shp) and MapInfo (tab) files. Once opened in Google Earth Pro, most of these formats can be saved as KMZ files.

Creating a New Placemark

To create a new placemark, first navigate to the location in the 3D Viewer where you would like to put the new placemark. Then you can create it by clicking the Add Placemark button on the toolbar or right-clicking the container listed in the Places Pane in which you would like to put the new placemark, and choosing Add, and then Placemark. There are other means of initiating this process as well. In either case, the New Placemark dialog box will appear.

While the New Placemark dialog box is open, the information inside can be edited and the placemark can be dragged to adjust it to its proper position. The various tabs can be used to access the placemark's properties including its name, description, the icon that is used to represent the placemark in the 3D viewer, the color of the icon and the label, and the orientation and zoom level of the 3D viewer that results when the placemark is double-clicked in the Places pane. You can create your own custom icons for your placemarks. Placemarks and other items can be edited after they are created or opened in Google Earth. Right-click (ctrl-click on the Mac) the item in the Places pane or in the 3D Viewer to open its Edit dialog box. While a placemark's dialog box is open, the information inside can be edited and the placemark can be dragged.

Placemarks can respond to mouse clicks by displaying information balloons that contain text, images, hyperlinks, and other structures that can be implemented in HTML. Information intended for display in the balloon should be entered into the Description text area. Images can be embedded directly into kmz files or can be stored on a server, such as Flickr, and referenced via http. There are advantages and disadvantages to each method of offering images.

It is important that you save your data periodically in a proper manner, so that if a problem occurs, you have safe copies of it. To save data properly, you need to understand how the items in the menu bar and pop-up menus function concerning the process of saving data.

To save an individual placemark, right-click its name (ctrl-click on the Mac) in the Places pane and choose Save Place As. Navigate to a folder where you would like to save the item as a file, give it the name you would like, and click the Save button. Your choices are to save it in KMZ or KML format. The default name for the file is based on the name of the item to be saved, and the default file type extension is kmz. In general, saving the file as a KMZ file is a good choice, because if the placemark contains embedded images that reside on a local storage device, copies of those images will be incorporated into the KMZ file, minimizing the likelihood that the file will become separated from essential content. It is also a good idea to make backup copies of your saved files.

Save to My Places is a less secure option, since it moves the placemark to the My Places folder, and depends upon Google Earth to save it for a future session. In a public facility such as a computer laboratory, where machines are shared by multiple users, the machines are often configured to log the user off after a certain duration of inactivity. It is possible that the managers of the facility have arranged for the My Places folder to be purged of added content when the session terminates.

It is a good idea to keep multiple copies of KMZ files and any other saved material that you value. Folders, documents, paths, polygons, and overlays, which are discussed below, can be saved in a similar manner to placemarks.

The File menu in the Google Earth menu bar provides another means of saving information. To save a feature or container as a file, make sure it is highlighted in the Places or Search pane and choose File -> Save -> Save Place As in the menu bar. Navigate to a folder where you would like to save the item as a file, give it the name you would like, and click the Save button. This option is risky, since if you have the wrong item highlighted you may mistakenly overwrite a needed file with content that you did not intend to save.

Drawing Paths and Polygons

The Add Path and Add Polygon buttons on the toolbar initiate the process of creating new paths or polygons, respectively. Once the corresponding dialog box opens, you can draw the path or polygon by either clicking or left-dragging the mouse. The tabs in the dialog box provide access to various properties.

Creating a new path in Google Earth. Points along the path can be added, dragged, or deleted and the information can be changed while the New Path dialog box is open. The Edit Path dialog box can be opened to alter the path after it has been created.

An elevation profile can be viewed along a path by selecting the path, then clicking Edit, Show Elevation Profile. This can also be done by right-clicking the path and selecting Show Elevation Profile.

The elevation profile will be in the units specified in the project, areas along the profile can be correlated to the corresponding line by moving the mouse within the cross section view.

Creating a new polygon in Google Earth. Points can be added, dragged, or deleted and the information can be changed while the New Polygon dialog box is open. While editing a polygon, it is a good idea to remove its fill so you can see the underlying imagery. To remove the fill, activate the Style, Color tab in the dialog box, and use the pulldown menu for Area to specify Outlined. The Edit Polygon box can be opened to alter the polygon after it has been created. Note that after you have selected a point in a polygon or path by dragging it or just clicking it, the next point you add will be topologically after that point. If you want to continue adding points, instead, after the most recent point you added, you will need to reselect that point first.

As is true of other work that you do, it is important to save your paths and polygons either by saving them individually, or by saving the containers, namely folders or documents, in which they reside.

See also Google Earth Help: Draw a path or polygon.

Creating Image Overlays

Digital maps can be added to the Google Image 3D Viewer as image overlays. They need to be adjusted to conform geospatially to the underlying Google Earth imagery.

To create a new image overlay, first navigate to the location where you would like to place the new imagery. Then click the Add Image Overlay button or right-click the container listed in the Places Pane in which you would like to put the new overlay. There are other means of initiating this process as well. In either case, the New Image Overlay dialog box will appear.

Use the slider to control the transparency of the image so you can move, rotate, and stretch it, using the available green handles, to fit the underlying Google Earth imagery. Once you are satisfied with it, you may make it opaque again. The tabs allow you to control other properties of the overlay. One of the useful settings is the Draw Order which is available in the View tab. Since overlays cover the area where they are situated on the globe when they are visible, they inevitably obscure other overlays that they overlap if those overlays are drawn first. If you have a preference for the order in which overlays in a set are drawn, assign low Draw Order numbers to the ones that you would like to appear on top so that they are drawn last. The ones with the highest numbers are drawn first, and get covered up by ones with lower numbers if they occupy the same parts of the globe. Click OK when you are satisfied with the overlay's location and other properties. Remember to save your work in a file.

While you are creating overlays, it is a good idea to have the Terrain layer deactivated. During the creation of overlays of map images that include national or state boundaries, it may be helpful to have the Borders and Labels layer active as a guide for adjusting the placement of the image. The Terrain layer does need to be activated in order to get the elevation reading in the lower right of the main window to work.

Using Layers

Google offers a huge amount of mappable data from its database through the Layers Pane. The growing set of layers include roads, volcanoes, 3D buildings, terrain, borders and labels, weather, photographs, earthquakes, news, YouTube video, and much more.

The layers are arranged hierarchically, with some of the layers containing several levels of sub-layers. To expand a layer listed in Layers Pane, so that you can see a listing of its contents, click the + sign to its left. You can collapse it later by clicking the - that appears. As with items in the Search and Places panes, you can control visibility of the layers with their checkboxes.

Layers Pane

The Terrain layer has a special status. While it is activated, the Earth's landscapes appear in 3D. This especially apparent when the 3D Viewer is tilted so that there is a horizontal component to the user's perspective.

Organizing Your Work

Vectors (placemarks, paths, and polygons) and overlays can be organized into containers such as folders and documents. Vector features can be assigned styles, which in the case of placemarks control color, opacity, size and the icon, and with paths and polygons, control color, opacity, and thickness of lines. Polygons can be filled or outlined.

Making Sure you Save Your Work Properly

When saving your work, be sure to specify the container that contains your data as the item that will be saved. When the container is saved in a KMZ file, the contents of the container will be saved along with it. Right-clicking (ctrl-click on the Mac) the item in the Places pane and choosing the Save Place As item in the contextual menu that appears is the best way to save your work because it minimizes the likelihood that you will be mistaken about what you have saved.

The Menus

Some of the functions of Google Earth can be accomplished through the menu bar at the top of the interface.

The File menu offers options that deal with opening and saving files

The Save Place As option in the File Menu has a similar function to the Save Place As option in the contextual menu that appears when you right-click an item in the Places or Search Pane. If an item is highlighted when you choose this option from the file menu, the dialog box will enable you to save that item. If nothing is highlighted you may be prompted to save the My Places folder along with its contents in the Places Pane. The hazard with using this option from the File menu is that if you are mistaken about what is highlighted, you may not be saving the work that you intended to keep. There is a danger that when you exit Google Earth, your work will be lost. The safe thing to do is to right-click and save the intended item through the contextual menu.
Tools Options Menu

The Options item in the Tools menu opens a dialog box that enables you to control many settings for Google Earth. With the five tabs that are available, you can control the units that are used to display latitude and longitude, and elevation, the vertical exaggeration of the terrain layer, fonts, tour settings, and many other parameters. On the Macintosh, the Options item is in the Google Earth menu.

Google Earth for Web (available for Chrome, Firefox, Edge, Opera)

Google Earth for Web is a browser-based version of Google Earth that allows quick viewing of kml and kmz files on a map. Its ease of use is beneficial, but it has some limitations, such as difficulty in creating kmz files, and inability to calculate area of polygons, producing elevation profiles, animations, and many others.

If one has difficulty with loading Google Earth for Web, it is recommended to edit your browser settings so that hardware acceleration is enabled.

Google Earth for Web can be used to search for locations, view tours from the Voyager, load kml and kmz files, and measure distance.

To import kml files in Google Earth for Web, the settings must first be edited to enable kml file import.

Creating a placemark in this new, browser-based Google Earth requires a bit of a workaround. First, one must go to mymaps.google.com and create a new map. Then, one must add a layer. This new layer should be renamed for clarity. Add a marker or line, then export it to a kml. Now the kml can be loaded into Earth for Web.

Earth Engine

Earth Engine is available as a development interface for viewing and running analyses on remotely sensed imagery. The Explorer can be used to view datasets that are available to the public. After signing in to a google account, users can also import data, run simple analyses, and export the results. The Engine Code Editor requires signing in to a google account and also registering for Earth Engine access by providing information about institutional affiliation, etc. Logging in to the Engine Code Editor allows the user to write their own codes to customize image and vector processing tasks.
