What is a .ETA file?
The file extension .ETA stands for a Google Earth Placemark File. This type of file is created by Google Earth, which is a program that allows you to explore the world through detailed satellite imagery and maps. An .ETA file contains a placemark or marker that pinpoints a specific location on the globe. This location is defined by geographical coordinates, including longitude and latitude. Additionally, the file can specify how the location should be viewed in Google Earth, including the zoom level, rotation, and tilt of the view, providing an overhead perspective of the chosen location.
To open an .ETA file, you would typically use the Google Earth program. This software is specifically designed to read and display the data contained in .ETA files, allowing users to navigate to and explore the marked location.
It's important to note that the .ETA file format has been largely phased out and replaced by newer file formats, .KML (Keyhole Markup Language) and .KMZ (a compressed version of KML), in more recent versions of Google Earth. The .ETA format was originally used in an earlier program called EarthViewer 3D, developed by Keyhole Inc., a company that Google acquired in 2004. As a result of this acquisition and the evolution of the software, Google Earth transitioned to using the more versatile KML and KMZ file formats for placemarks and other geographic data.
