Google Earth

Definition

Google Earth is a digital globe, map and geographical information program that was originally named EarthViewer 3D created by Keyhole, Inc, a Central Intelligence Agency (CIA) funded company acquired by Google in 2004. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and geographic information system (GIS) 3D globe.

What is Google Earth?

Google Earth is a comprehensive geospatial software that renders a 3D representation of Earth primarily based on satellite imagery. The program furnishes an extensive array of features including satellite views, earth maps, and other geographical information. The software visualizes geospatial data on a high-resolution, three-dimensional globe on your computer.

This platform has a robust set of instruments for viewing photos, landmarks, distances, buildings, and areas around the globe. It provides direct access to a vast repository of satellite images. It's crucial to note that the images available are not live but are recent enough to be useful for most tasks. Users can navigate through the wide geographic content, save viewed places, and collect routes, placemarks, and share them.

Moreover, Google Earth supports a sundry of map layers such as roads, 3D buildings, trees, panoramas, weather, and even enables accessing the past satellite images of a particular region. Through the Street View feature, it's feasible to see photos from many positions offering a panoramic view at street level.

A powerful tool for geospatial analysis, Google Earth is widely used in different sectors including civil engineering, environmental, meteorological applications, and in numerous fields that call for a geographic visualization tool.

FAQs

What is the difference between Google Earth and Google Maps?

Google Maps and Google Earth are two completely different technologies. Google Maps is a more basic, quick tool, offering street and satellite maps, as well as street views and can function as a route planner for traveling by foot, car, bike, or public transportation. On the contrary, Google Earth has more robust features and comprehensive geospatial data, including 3D topography and building, toolset for measuring distances, and the ability to view historical imagery.

What types of images are available on Google Earth?

Google Earth provides access to satellite images, aerial photographs, and even 3D representations of many regions of the world. These images are usually taken by satellites, aircraft, and Google's own car and backpack cameras for street view imagery.

Can Google Earth be used for real-time navigation?

No, Google Earth is not designed for real-time navigation. While it does show the user's current location, it is meant for viewing and studying geographic data rather than real-time navigation or GPS tracking.

Is Google Earth free to use?

Yes, Google Earth is free for personal use. There is also a premium version called Google Earth Pro that offers additional features like advanced data import capabilities, higher resolution printing, and more detailed measurements.
