Google Earth is a web-based mapping and geospatial data visualization tool developed by Google. It allows users to explore the Earth's surface and view satellite imagery, maps, 3D buildings, and other geographic information from various locations around the world.
Google Earth provides a virtual globe that users can navigate and interact with using their computer or mobile device. The platform utilizes satellite imagery, aerial photography, and GIS (Geographic Information System) data to create a detailed and realistic representation of the Earth's surface.
With Google Earth, users can zoom in and out, tilt and rotate the view, and explore different locations at various scales. They can also search for specific addresses, landmarks, or points of interest and view additional information such as photos, reviews, and related web content.
Google Earth offers several features, including Street View, which allows users to explore panoramic street-level imagery of many cities and towns around the world. It also includes historical imagery, which enables users to view past satellite images and observe changes in landscapes over time.
Additionally, Google Earth provides tools for creating and sharing custom maps and placemarks, measuring distances and areas, and recording virtual tours. It is widely used for educational, recreational, and professional purposes, allowing individuals to discover and learn about different places, plan trips, conduct research, and more.
