What is Google Earth?

Google Earth

Google Earth is a 3D mapping program that lets you “fly” around the globe by viewing satellite imagery. It offers various levels of resolution for different parts of the world.

Utilizing navigation controls, you can move and tilt your view perspective. In addition, clickable placemarks or polygons may be used to highlight specific locations.


Google Earth is a virtual world map that lets you zoom into any location on Earth using satellite imagery, including photos from above the atmosphere and superimposed extra data such as street maps or 3-D models of buildings. Furthermore, this program offers a digital elevation model which shows views from different altitudes around Earth as well as 3-D fly-throughs of city streets and major landmarks.

Your view of the world can be customized by turning on or off various “layers” which provide various types of geographical and political data. For instance, use the Find Businesses layer to quickly locate restaurants and other points of interest nearby. Google partners with organizations like National Geographic and “Sesame Street” in providing educational layers specifically targeted toward children.

Google Earth makes it possible to visualize how cities have changed over time by providing historical images of locations. You can take a visual tour from 1984 up until today if desired, or view cities from above by clicking an airplane icon. Furthermore, its current version offers an exciting flight simulator, where users can select between an F-16 fighter jet or an SR22 propeller plane before entering their virtual cockpit – you can control this using joystick controls as well as keystrokes or mouse clicks!

Wild Sanctuary, an overlay that plays sounds recorded by wildlife and nature researcher Bernie Kraus, can also be an intriguing feature. When clicked upon, these sounds will play in a pop-up window adjacent to each marker.

Google Earth is available free, but subscription-based versions for business users who require more advanced capabilities exist. Google Earth Pro, for example, gives access to high-resolution imagery as well as tools for data integration and advanced analysis. Furthermore, KML (Keyhole Markup Language) file support enables sharing data among applications; there’s even a mobile version which can load KML files as well as search functionality for smartphones and tablets.


Google Earth is a virtual globe map that shows satellite photographs of most locations on earth. Images range in detail, from birds-eye views to street level perspectives, while additional data such as maps, 3D buildings views, relief imagery can also be added on top.

Maps provided by various sources and are continuously updated through this software program are regularly provided for users to download and add data in KML (Keyhole Markup Language), an open standard for sharing geographic data online, enabling students, teachers and researchers alike to create their own maps using this software.

As people first experience Google Earth, their reactions vary; one is often overwhelmed with its unprecedented access to the world; another may feel unnerved by potential for voyeurism and privacy breaches; zooming in on someone’s home may result in neighbors viewing inside it or burglars scoping out potential targets in your neighborhood.

Google Earth contains many features designed to protect privacy; however, some privacy concerns still remain. For instance, users are able to search addresses and enter coordinates to see specific locations around the world. It is also easy for private property to become revealed accidentally through clicking.

Google Earth remains a very useful way for exploring different parts of the world, providing access to beaches, neighborhoods, fishing spots and hiking trails as well as being used for research. It can help discover beaches, neighborhoods, fishing spots and hiking trails as well as being used as part of education or research purposes.

This program works on many computers and is highly portable; users can download it onto a tablet computer or mobile phone and take it with them when traveling abroad to take in local sites.

Google holds several software patents related to how it displays maps on Google Earth, specifically through mip mapping and clip stacking techniques. The idea behind mip mapping and clip stacking is creating a virtual texture of earth’s surface using bitmap images arranged in an inverted pyramid shape with double resolution of those below, before saving these into files on computer as “mip maps” that can be rendered quickly when rendered by rendering software.


Google Earth gives a stunning bird’s-eye view of our world from your computer screen, using satellite imagery, aerial photography and GIS data to generate three-dimensional maps of planet Earth. Users can search for locations using navigation controls to zoom in/out/tilt the view/rotate the globe; in addition to providing an entertaining new perspective it provides useful features that make Google Earth an indispensable resource for students and researchers.

Google Earth Help provides general usage guidelines that outline limitations on printing content from the program and must attribute any downloaded information correctly. When clicked, a PDF document opens that details even further tips for using Google Earth.

Before using Google Earth, it is necessary to locate your desired area on a map of the world. You can do this by typing the name of a city or country into the Search Bar; once a list of possible locations appears in the Places Panel, click any one to zoom into that particular spot.

Once zoomed in, the terrain will appear flat from a top-down view. With navigation controls at your disposal, tilting can be changed anywhere between 0 and 90 degrees to give a wide-angle perspective that includes the horizon.

If you want a virtual tour of global landmarks, select the “Sightseeing” box. This will display some popular destinations like Paris’ Eiffel Tower and Arizona’s Grand Canyon as well as allow users to add custom files or download tours created by collaborators. Furthermore, Google Earth Community provides a forum where members can discuss the program, share custom files, discuss troubleshooting tips or offer help for problem areas.

Historical imagery

Google Earth is an innovative geomapping and tagging program that digitally stitches together billions of satellite and aerial images into an immersive panoramic map of our planet. Google Earth makes an effective tool to track climate change, discover unknown geographic and ecological features, record history and document global events. Free to use but there are paid versions with advanced features or commercial applications available as well.

This program can be installed as either an application or browser plug-in and requires minimal hard drive space due to Google servers storing imagery that can be streamed directly back out. Desktop versions can be accessed using any computer running Windows, Mac or Linux while mobile apps for Android and iOS are also available.

Google Earth stands out as one of the world’s premier mapping applications with its ability to show what an area looked like at different points in time. While this feature can be found on desktop and mobile apps, accessing it may prove tricky at times.

Google Earth features imagery from within three years, but the company continually adds updates for different areas around the globe – cities more so than sparsely populated ones. Zoom in to an area and then access older satellite images from that spot.

Google Earth also features time-lapse videos that allow users to see how the landscape has changed over a three year period, accessible both from its website or YouTube directly. These time-lapse videos can be watched directly through either platform.

Google Earth features many third-party overlays which can be activated to display natural wonders, impressive achievements, environmental efforts and political issues. One such overlay from the United States Holocaust Memorial Museum highlights villages destroyed during Darfur crisis due to Janjaweed militia activity in Sudan.

Google Earth Pro is designed for businesses requiring fully customized solutions for geospatial data integration and high-resolution imagery, including measurements, integration of geo-spatial data sets and high resolution imagery. This solution comprises an enhanced version of the Google Earth program coupled with a server with advanced features for measurement data integration and high resolution imagery.
