Google Earth is a three-dimensional model of the globe. Maps and satellite images of streets and cities allow the user to pave the route, get acquainted with the terrain or simply admire the attractions located anywhere in the world.
How to use Google Earth
Unlike similar services submitted by other developers, the application of Planet Google Earth must be downloaded and installed on your PC. This is necessary to use additional features that are missing in web versions.
The program initially downloads basic information from the network, and upon subsequent launches only downloads additions. Thanks to this user, it is possible to significantly save traffic.
The developers have provided a simplified version of Google Earth intended for mobile devices. The appendix has functions for creating personal images in order to impose them to pictures from the satellite.
Among the additional functions of the program are noted:
Built-in Movie Maker tool;
Adding addresses to the card;
Measurement of distances and squares;
Availability of addresses and names of large objects, refueling, shops, etc.;
The ability to travel to Mars, the Moon or the bottom of the oceans.
Features of the Planet Google Earth
The main advantage of Google Earth is considered high image resolution. Some big cities And the capital of the world was removed as clearly as possible.
The user can enable geodata layer, which is synchronized through a network with a relevant information base.
The presence in the program of the "3D-building" function allows you to see three-dimensional models of significant structures, historical and architectural monuments.
In Google Earth, an air surveyor is built, thanks to which you can make "flights" above the Earth and by Star Sky. To activate it, press the Ctrl, Alt, A. keyboard shortcut.
IN recent versions Developers have implemented the function to put routes. They can be both short to the nearest store or pharmacy and long - in another city and even the country.
Among the advantages of the program, it is necessary to note the ability to "travel" without leaving home. Clear image, wide functionality and user-friendly interface make the use of Google Earth as comfortable as possible.
Versions Google Earth.
- Browser version of Google Planet. In a matter of seconds, you can be at any point of the Earth and visit many cities and places in three-dimensional mode. Right in the browser window you have access to a "explorer" - travel with famous scientists and familiarity with the cultures of various nations.
- Mobile application "Planet Earth" for installation on a tablet and smartphone.
- Earth Pro version with advanced card creation tools. Import and export data GIS, view pictures over past periods of time, and much more.
Differences of the pro-version of Google Earth

- import vector files,
- adding addresses on the land map.
Google Earth real-time viewer online. No need to download Google Earth a separate application. Thanks to the interactive placement of the Earth, they automatically load the browser. It is enough to visit the site that photos and 3D buildings model have become available from any gadget, computer, smartphone. Each Internet user at least once visited Google's resource. This portal offers a single map of the entire globe with the ability to study objects in 3D. High accuracy pictures allow you to travel on all continents, while staying at the same time.
Internet speed key moment. Due to high speed, detailing occurs within a few seconds. Although mobile Internet will also allow you to download cards, but it will take much more time. An alternative becomes Google Earth desktop version.
Satellite pictures
The main part occupy photos from the satellite. Some made of aircraft or other aerial photography equipment. Maps detailed, and in some pictures there are cars and people. The main emphasis is done on the streets, buildings, attractions.Use the satellite snapshots as a manual for studying the relief, the characteristics of the terrain, climate change, etc. Some scientific centers turned into a tool for their professional activities.
3D cards planet
In the innovation, download the program for downloading Google Earth in such technologies is considered to be detailing in 3D. With the help of DirectX and OpenGL, all structures look as much as possible. Also, all the altitude ratios are preserved: you can clearly define the house on the mountain from the building in the lowland.However, 3D models will require the user to use a powerful device. Not all computers and smartphones are capable of working correctly with three-dimensional models - ordinary pictures from space are viewed without problems.
Many users are interested in online satellite maps, giving an opportunity to enjoy the view of the favorite places of our planet from the height of a bird's flight. There is enough number of such services in the network, while all their diversity should not be misleading - most of these sites use the classic API from "Google Maps". However, there are also a number of resources using their own tools for creating high quality satellite cards. In this material, I will talk about the best high-resolution satellite maps available online in 2017-2018, as well as explain how to use them.
When creating satellite cards of the earth's surface, both snapshots from cosmic satellites and photos from special aircraft, allowing photographing at the height of bird flight (250-500 meters).
The satellite cards created in this way are regularly updated, and usually pictures with them have age no more than 2-3 years.
Most network services do not have opportunities to create their own satellite cards. Usually they use cards from other, more powerful services (usually google MAPS). At the same time, at the bottom (or at the top) of the screen, you can find a mention of the copyright of any company to demonstrate maps data.
Viewing satellite real-time satellite cards is now not available for a regular user, since such a toolkit is used mainly for military purposes. Maps are available to users, photos for which over the past months (or even years). It is worth understanding that any military facilities can be deliberately naked in order to hide them from interested parties.
Let us turn to the description of the services that allow us to enjoy the capabilities of satellite cards.
Google Cards - View from Space in High Resolution
Bing Maps - Satellite Card Service Online
Among the cartographic online services of decent quality, it is impossible to go through the "Bing Maps" service ("Bing Maps"), which is the brainchild of Microsoft. Like the other resources described by me, this site provides quite quality photos Surfaces created using satellite and aerial photographs.
Service "Bing Maps" - one of the most popular cartographic services in the USA The functionality of the service is similar to the above-described analogues:
In this case, using the search button you can define online the location of a particular satellite, and clicking on any satellite on the map you get a brief information about it (country, size, launch date, and so on).
Conclusion
To display high-resolution satellite cards online, it is worth using one of the network solutions listed by me. The largest popularity in the global scale has the "Card Google" service, therefore I recommend using this resource to work with satellite cards online. If you are interested in viewing geolockations in the territory of the Russian Federation, it is better to use the toolkit "Yandex.Maps". The frequency of their updates in the relations of our country is superior to the same frequency from Google MAPS.
The evolution of cards, navigation and orientation on the ground occurs in our time. Now! The first travelers and pioneers used paper cards, cards drawn on stones, wooden planks, skin and other objects. Currently, few people represent themselves without electronic navigation, satellite cards, cellular ... New technologies are coming.
Let's analyze some of the features that provide us with technology in the field of observation and navigation at present. Look at the story.
Creating the first artificial satellites of the Earth
The idea to use satellites as repeaters arose long before they were launched into orbit first satellite.
For the first time to remove the aircraft in the upper layers of the atmosphere attempted engineers fascist Germanyby creating a managed missile "Weapon of Retribution".
Hitler's goals did not achieve their goals, but attracted the attention of many specialists to the development of missile weapons. People began to think about the possibilities of using managed missiles for scientific purposes.
One of the officers of the British army, the fiction writer Arthur Clark, in 1945 published an article in the magazine "Wireless World", where he proposed the principle of satellite communications and the possibility of transformation of such missiles to "unearthly repeaters".
On June 26, 1954, Korolev presented to the Minister of Defense Industry Dmitry Ustinov's memo " About the artificial satellite of the earth».
Work began on the project "ISS".
October 4, 1957 at 22 h 28 min. Moscow time "Satellite-1" was led into orbit. He began to feed the first signals from the space after separation from the last stage of the rocket. It was a metal ball with a diameter of a half-meter with the simplest radio transmitter.
In 1967, the system of Russian satellite TV "Orbit" began to operate. She allowed the Earth through an artificial satellite to transfer one central television program: "Channel One".
Satellite Cards in Real Time
Space opening began with interactive maps - Photos of land obtained from the satellite. This significant event occurred on August 17, 1959, thanks to the American artificial satellite "Explorer 6". The era of satellite photography began.
Let us dwell on the services that have open access.
Such services have appeared as Google maps, which remains the most affordable resource for the usual alignment.
(To move around the map, zoom, reduce the map, image angle changes Use the navigation in the form of arrows and characters + and - at the top of the card. Try also, manage the card, holding the right mouse button)
View world map and photo from the satellite, determine the coordinates of any point of the planet, measure the distances between objects, calculate the area and pave the route using new satellite cards.
(Map can be increased or decreased)
If Google's cards provide static information, that is, snapshots from the satellite are not shown in real time, that is, devices that provide such an opportunity.
For example, with the help of a satellite receiver "Baikal" can be obtained photos and Satellite Cards in Real Time.
Satellite weather receiver Baikal is designed for receiving images of the earth's surface with meteorological vehicles located in low-bit and geostationary orbits operating in the frequency range of 137-138 MHz with frequency modulation of the signal in APT modes (NOAA15, NOAA17, NOAA18, NOAA19) and WEFAX (METEOSAT7, Goes). The receiver can be installed both in stationary and mobile objects, such as a boat, yacht, sea or river vessel, icebreaker or car. Reception of the picture is possible even while driving.
Services, Services, Opening ...
With the help of Google and other platforms, enthusiasts come up with all new and new services:
The development of services similar to Google projects is engaged in several startups. One of them, the American company SKYBOX, launching satellites into space. The goal is to make observation of real-time land more affordable. Its vision of the future project company has demonstrated a video showing Chinese international Airport Skybox satellite SKYBOX.
At the moment one satellite works in orbit. Total is planned to start 24 satellites, to cover the entire planet. The satellite weighs only 120 kilograms, and its size is 60 * 60 * 90 centimeters. Shot details - up to 90 centimeters per pixel.
If someone is content with satellite cards in real time, they found those who seemed a little. Employees of the studio of interactive systems from "Georgia Institute of Technology" went on and offered real-time planet surveillance project In a three-dimensional review.
To develop this system, navigation systems, satellite repeaters, webcams, services such as Google Earth and Microsoft Virtual Earth will be used.
Modern Internet gives really a lot of useful opportunities to those people who are looking for them. For example, an amateur of geography or just beautiful species can be a very interesting Virtual Globe of Earth, made in 3D.
The network you can find enough many services offering to see and explore the map of the earth globe online. Naturally, I want to consider the most interesting of them.
Mother Earth - one of the most visual virtual earth globes
Indeed, this particular option suggests not only the globe of the earth online, but also provides a number of possibilities for changing the resulting image.
What does that require:
- Go to home page online service http://oos.moxiecode.com/js_webgl/world/index.html, where 3D model will be presented in it classic version on the background of the starry sky and our sun;
- The image can be easily rotated in different directions, driving turns using a mouse;
- What is the most important thing - everything is absolutely free!
If desired, you can easily change the display option. To do this, you need to pay attention to the small menu, placed in the upper right corner of the working screen. In addition to classic, there you can detect six more options for the Virtual Globe of the Earth:
- Blocks - Displays the continents of the planet in the form of peculiar blocks.
- Geodesic - makes it possible to evaluate relief.
- Lines - Similar to the previous option, only the model is presented in the form of spectacular vertical lines.
- Horizontal Lines - as it is clear from the title, the line will now be located horizontal. It looks very interesting.
- Half Spheres - It turns out something fantastic using a hemisphere.
There is another option - Particles. What exactly it shows, it is not entirely clear. But it looks very original. Perhaps these are ties of communication that transmit their signals across the entire planetary network.
Alternative online services
From alternative online globic planets worth paying attention to the three options presented at www.Webglearth.com. This resource offers quite an interesting alternative:
The last option is a real find for historians who do not have the opportunity to get to Rome and personally consider this relic.
