I’m looking for a map software that covers topography and landforms, not transportation and tourism. It’s best to be able to detail it down to the town level.

Google Earth (GE) is a virtual globe software developed by Google. It arranges satellite photos, aerial photography and GIS on a three-dimensional model of the earth. Google Earth was launched globally in 2005 and was named one of the 100 best new products in the world in 2005 by PC World Magazine. Users can browse high-definition satellite images from around the world for free through a client software downloaded to their computers. Google Earth is divided into two types: free version and professional version.

Google Earth Satellite Photos

Google Earth is a virtual globe software developed by Google. It was officially launched to the world in 2005. It arranges satellite photos, aerial photography and GIS on a three-dimensional model of the earth. It uses public domain images, licensed aerial photography, images from the KeyHole spy satellite and many other satellite photos of cities and towns. It even provides pictures that Google Maps doesn't have. Google Earth 6 comes in three different versions for the desktop: Google Earth, Google Earth Pro, and Google Earth Enterprise. Fly anywhere and view satellite imagery, 3D buildings, 3D trees, terrain, Street View, planets, and more. The software supports multi-terminal browsing applications. Whether you use a computer, mobile phone, tablet, or browse the web, there is always a version that is suitable for you.

Google Earth allows you to travel to anywhere in the world to view satellite imagery, maps, terrain, 3D buildings, canyons and oceans from galaxies from outer space. You can explore rich geographical content, save your visited places and share them with others. Three exciting new features have been added to the latest version: Historical imagery from around the world If you're curious about how your surroundings have changed over time, Google Earth can now take you back in time. With just a click, you can observe changes in suburban expansion, melting ice caps, and coastal erosion. Seafloor and sea-level data from ocean experts In the new ocean layer, you can sink all the way to the bottom of the ocean, view exclusive content from partners like the BBC and National Geographic, and explore the remains of 3D shipwrecks like the Titanic. Streamlined tours with audio and video recording. Further mark landmarks and record unlimited journeys in Google Earth. Just turn on the tour, press the record button and you can see the whole world. You can even add background music or voiceover to make the journey more personal. Google Earth integrates Google's local search and driving guide services to provide a bird's-eye view of the world and will replace the current desktop search software. He can fly freely in the Grand Canyon like an eagle in the virtual world, land on the top of the canyon, and dive into the abyss of the canyon. The 3D map positioning technology used by Google Earth can push the latest satellite images on Google Map to a new level. Users can search for a specific area on the 3D map, zoom in and out of the virtual image, and then form a driving guide. In addition, Google Earth has also carefully crafted a special option - a bird's-eye view of the journey, which makes motorists more energetic. Google Earth mainly achieves these above-mentioned functions by accessing Keyhole's extended database of aerospace and satellite images. The database was updated last week. It contains a large amount of terrain data provided by NASA, and will cover more terrain in the future, including pastoral areas, wastelands, etc. GE's personal version has three versions. GOOGLE has designated the lowest version as Free software, which can be used freely without time limit. The Plus version ($20/year) and Pro version ($400/year) are both free! Now there are Mac and Linux versions. The difference between these versions is that the Plus version and the Pro version add some functions such as drawing lines/polygons, GPS navigation, statistics, etc., but their global landform images and 3D data are the same, and there is no Plus version or Pro version. version of the image quality is better.

Google Earth is free for personal use. Its main functions are: 1. Combined with satellite images, maps, and powerful Google search technology; global geographic information is right in front of you. 2. From a space odyssey to a glimpse of the neighborhood 3. Enter the destination and zoom in directly 4. Able to search for schools, parks, restaurants, hotels 5. Get driving directions 6. Provide 3D terrain and buildings, and its browsing perspective supports tilting or rotating 7. Save and *share searches and favorites 8. Add your own notes 9. You can fly the plane yourself. 10. You can also see Mars and the moon 11. You can measure length and height 12. There is a rare animal tracking system Note: During the Dragon Boat Festival in 2010, Google launched the latest version of GE5.2, the most eye-catching of which is the weather function. It can display local weather conditions in real time, including rain, wind, thunder and lightning, and temperature.

Wherever you see it raining on GE, it is really raining there, in real time.

Google Earth includes atmospheric effects, seabed, and brief star imagery. The "clarity" measurement here is the "Eye alt" value displayed when the image is closest to the ground and the clearest. Image clarity is around 5 miles in most areas. Nearly every nation's capital and major metropolitan areas provided relatively clear images, with a resolution of 0.15 miles (241.4016 meters). North America, Europe and Japan have more high-definition images, while other regions have fewer. Terrain Surface: When the "Terrain" effect is turned on, you can observe terrain such as plateaus and mountains displayed in 3D. Seabed: You can explore the seabed, and the seabed is displayed in 3D. Data year: Generally less than three years.
