Google Earth is a database browser of geographic information data. Features within the software include geographic data, bathymetric data, topography, locations of volcanoes and mountains, tectonic boundaries, trivia, and other information related all over the world.
Unlike GoogleMaps, the software can rotate and change the tilt of Earth’s view. The elevation data presented in Google Earth came from NASA’s Shuttle Radar Topography Mission (STRM) which makes it possible to view any locations in actual terrains and morphology. Google Earth can read file extensions like KML (Keyhole Markup Language), KMZ (Keyhole Markup Language Zipped), and TIFF (Tagged Image File Format) which is helpful for professionals for exporting and importing data to and from Google Earth.
Google Earth is a tool to explore the world and locate aerial images of any location. You may also immerse in a 360-degree perspective using Street View to see the world as a traveler. Other features highlighted in GoogleEarth include 3D buildings, photos of historical sites and tourist spots, weather data, parks and recreation areas, city boundaries, and other more. You may also annotate and sketch areas of interest using the polygon and path tool. If you want to determine the area of a location, the software can automatically calculate the distance and area.
You may save locations and record their geographic coordinates using the placemark tool. Overlaying of maps can also be done on the software like hazard maps, population density maps, and other pertinent maps. Not only the view of Earth but also the view of Stars, the Moon, and Mars can be done on Google Earth.
You may access Google Earth online or you may download the software for free in your mobile device or on your desktop. There are five versions of Google Earth. The versions are Google Earth Pro, Google Earth for Web, Google Earth for Mobile, Earth Engine, and Enterprise.
Google Earth Pro is a desktop version of the software that can be downloaded on PC, Mac, or Linux. It is free to use and includes a significant number of features as forementioned. It can import and export ESRI shapefiles, Mapinfo files, and other Geographic Information System (GIS) software. You may create new layers of digitized maps using the polygon tool, import Global Positioning System (GPS) data via Microsoft Excel.
Another version is the Google Earth for Web. This version of Google Earth can be accessed using different browsers namely Chrome, Firefox, Edge, and Opera. Unlike the desktop version, Google Earth for Web has limited functions. Despite the limitations, it can still import KML and KMZ files, search for locations of places, and has an additional option called the Voyager. The feature can show the famous collection of historic and tourist spots that are contributed by various travelers from all over the world.
Google Earth has also a version for Mobile devices. It performs the same functionality but cannot create new data. You may only search for places and use the Voyager feature. This version is available for Android and iOS devices.
The fourth version of Google Earth is the Earth engine. The main functionality of this version is that it merges satellite imagery and geospatial data using tools that can be developed by highly skilled individuals who can create and add their algorithms for data analysis.
The last version is Enterprise. In this software version, it is more exclusive to employees within a company or an organization performing the same functions for database management of imagery and geospatial data.
