At that time Google Earth is available in 45 international languages. Limited version is available free of cost and Google Earth Pro is available for $399/year. Currently Windows 2000, XP, 7 and 8, Linux, Android, iOS, Symbian, Blackberry Storm are supporting this application. Whenever a user search for a place, it automatically fetch the images from satellite and shows on the system. At that time its name was EarthViewer 3D later on changed by Google Earth. So paying for Google Earth Plus wont get you. In 2004, Google acquired this setup from Keyhole Inc. The imagery for all the versions of Google Earth (Free, Plus, Pro, Enterprise, etc.) are all exactly the same. Officially it was not developed by Google. This is also a mapping application being available by Google since June 11, 2005. Google Maps is very popular service in smartphone and since August 2013 54% smartphone users are using Google Maps. Google Maps are regularly updated by Google and most of the data is just 3 years old. Google Earth Pro allows you fly anywhere around the earth to view satellite imagery, maps, 3D building, and terrain, from galaxies in outer space to the canyons of the ocean. It will automatically calculate distance of two locations in different range if you wants to go through car, motorbike, bicycle or walking on foot. It is active since its launching date, February 8, 2005. With the help of this tool you can see the map and location of any street, road, building, country, city in image form via satellite. Google maps is a mapping application, which provides the users different maps in different style. When Google wants to fly their aircraft to snap high-resolution photos, they have to wait a long time to capture photos when it isn't raining or overcast.If you want to explore the Mars and Moon you can explore the surface of both planet by Google Earth, which is not offered by Google Maps. There'd be nothing to see! As such, it can sometimes take time for Google to get clear shots that aren't impeded by the weather.Īn example of this is London. There's no point snapping photos of a place that is constantly covered by clouds. Not only does it take time, but it also costs money to collect these images, compile them, edit them, and upload them. Also your drawing should display 6 decimals for meters-you attached images only show 4 and you need to fix that. Cad locations looks like it is due to not enough decimal places when you enter the lat/longs. They are also run by a number of private companies, not by Google itself, so getting all these images pieced together takes even more time. The difference between Google Earth locations vs. Obviously, it takes time for these aircraft to run those photography update missions. However, if your house is a barely discernible brown blob amidst a landscape of psychedelic blurs, then that's the work of a satellite suspended above the equator. When you zoom in on Google Earth, to the point where you can see your car clearly parked on your driveway, then that's the work of aerial photography. The same goes for no-fly zones and conflict areas. If you do not see the GeoTIFF in the correct folder, check that the file type is set to GeoTIFF. Google might also stop updating a certain area if they discover that the imagery is being used for military intelligence or crime. Open Google Earth Pro (available for download here. This is typically due to requests from governments or personal lawsuits. The images of these places may be old, blurry, or entirely blacked out. Some locations are rarely or never updated due to security reasons. This is because these areas are prone to greater change, but also because these areas are the most frequently searched and viewed by users.įor example, New York will update regularly with high detail images because Google can fly its aircraft to collect imagery and there will be many third-party companies to provide satellite imagery. LocationĪreas of interest or high density are more likely to be updated than rural villages. There's no schedule for how often Google Earth updates its images and there are various factors to take into account. From field survey data and manual calculation. Google collects some of its images from third parties, so the rate at which it can update parts of Google Earth is reliant on others. Therefore, this research aims to investigate the accuracy in distance and area of selected location using Google Earth Pro (GIS application software).
