High resolution satellite maps online. Satellite map of the world online from Google. Google Maps - high resolution view from space

They allow obtaining spatial information about the earth's surface in the visible and infrared ranges of electromagnetic wave lengths. They are able to recognize the passive reflected radiation of the earth's surface in the visible and near infrared ranges. In such systems, the radiation falls on the appropriate sensors that generate electrical signals depending on the intensity of the radiation.

In optical-electronic remote sensing systems, as a rule, sensors with constant progressive scanning are used. Can be distinguished linear, transverse and longitudinal scanning.

The total scanning angle across the path is called the angle of view, and the corresponding value on the surface of the Earth is called shooting bandwidth.

The part of the data stream received from the satellite is called the scene. Schemes for cutting the stream into scenes, as well as their size for different satellites, have differences.

Optoelectronic remote sensing systems conduct surveys in the optical range of electromagnetic waves.

Panchromatic images occupy almost the entire visible range of the electromagnetic spectrum (0.45-0.90 microns), therefore they are black and white.

Multispectral(multizone) imaging systems form several separate images for wide spectral bands ranging from visible to infrared electromagnetic radiation. The greatest practical interest at the moment is represented by multispectral data from new-generation spacecraft, including RapidEye (5 spectral zones) and WorldView-2 (8 zones).

Satellites of the new generation of high and ultra-high resolution, as a rule, are shooting in panchromatic and multispectral modes.

Hyperspectral shooting systems form images simultaneously for narrow spectral zones in all parts of the spectral range. For hyperspectral imaging, it is not the number of spectral zones (channels) that is important, but the width of the zone (the smaller, the better) and the sequence of measurements. So, a survey system with 20 channels will be hyperspectral if it covers the range of 0.50-070 μm, while the width of each spectral zone is not more than 0.01 μm, and a survey system with 20 separate channels covering the visible region of the spectrum , near, shortwave, mid and longwave infrared regions, will be considered multispectral.

Spatial resolution— a value that characterizes the size of the smallest objects distinguishable in the image. The factors affecting the spatial resolution are the parameters of the optoelectronic or radar system, as well as the height of the orbit, that is, the distance from the satellite to the object being photographed. The best spatial resolution is achieved when surveying at nadir, while deviating from nadir, the resolution deteriorates. space pictures can have low (more than 10 m), medium (from 10 to 2.5 m), high (from 2.5 to 1 m), and ultra high (less than 1 m) resolution.

Radiometric resolution is determined by the sensitivity of the sensor to changes in the intensity of electromagnetic radiation. It is determined by the number of gradations of color values ​​corresponding to the transition from the brightness of absolutely "black" to absolutely "white", and is expressed in the number of bits per pixel of the image. This means that in the case of a radiometric resolution of 6 bits / pixel, we have a total of 64 color gradations, 8 bits / pixel - 256 gradations, 11 bits / pixel - 2048 gradations.

What are Google Maps? This is a service that consists of several free applications and includes a map site Google Maps and a program for laying a route (Google Transit). Maps from Google offer a satellite view of many cities on the planet and include a detailed layout of streets, houses, ways to travel by public transport or car, a guide to various objects, and more.

Features of work

The Google Maps map is displayed in two variations:

  • conventional traditional map (similar to Mercator maps)
  • and satellite images (not online, but taken a certain time ago).

The scale of the maps is also based on the Mercator projection, that is, it is constant and changes from the poles to the equator in the direction of decreasing.

Another separate project of the corporation is closely connected with Google Maps - Google Planet, which corresponds to the globe, on which the regions of the Earth's poles are clearly visible.

For which places are satellite images offered? Not for everyone, but only for big cities in Russia, England, America, Canada and others.

Not all governments have approved such posting and use of images. That is why many objects on the maps are shaded. Such "secret" objects include, for example, the White House or the Capitol.

Different places on satellite images are given in different resolutions - the less populated the area, the less detailed it is. Also, some places in the pictures may be hidden due to the shadow of the clouds.

  • switch to satellite mode- lower left corner;
  • zoom in/zoom out- lower right corner.

As soon as the company introduced a new service, a wave of interest in satellite images swept around the world.

The creation of sites began, on which satellite images began to be placed in the public domain interesting places, unusual architectural sights, stadiums, man-made formations.

Since 2008, the US Weather Service has been using Google Maps to prepare its forecasts.

It should be noted that not all images are made from a satellite - most of the images were obtained thanks to aerial photography from a height of 300 meters.

Google Maps online maps make extensive use of JavaScript. As the user moves around the map by dragging it, new parcels are loaded from the server and displayed on the page.

If the user is looking for specific objects, then the search result is inserted in the sidebar, and the page itself does not require a reload. The location on the map is displayed dynamically through a red marker icon.

  • In 2006 year, the first version appeared for mobile phones, and in 2007 a second version appeared. A GPS-like service is used to locate the phone.
  • In 2008 year Google Maps could be used for Android, Windows Mobile, Symbian, BlackBerry, Java (from 2+), IOS (Apple), Palm OS (Centro+).
  • In 2011 year, the corporation announced that it was providing mapping service over 150 million customers.

So that owners of third-party sites could use Maps, Google announced a free service in 2005. API Maps(Application Programming Interface).

The map can be placed on any site using this technology for software interaction. To date, there are more than 350 thousand such sites around the world.

satellite map Russia - high-resolution images taken from space by orbital stations. The image that the user sees is made up of many individual shots. The high quality of the equipment used at the orbital stations made it possible to achieve the highest quality of shooting. As a result, on the screens of mobile devices, PC monitors, high-precision high-resolution images are available to us, the image on which is very accurate and clear.

Satellite map of Russia in real time displays high-resolution images. You can see almost all Russian cities on them. By zooming in and out of objects, moving the cursor over individual sections of the map, it will be possible to examine streets, buildings, individual structures and squares. How more value of the city, the more detailed will be the section of the satellite map for it.

Satellite map online in real time 2016 - exploring the country together

High resolution satellite maps online 2016 - a collection of high-precision images through which you can study settlements different magnitudes at a particular point in time. The user, choosing the object and scale he needs, gets his picture at the same time. By choosing the appropriate parameters, instead of the "satellite view" mode, you can display an image:

  • landscape view;
  • a schematic representation of Russia, its individual cities;
  • satellite view - real image.

High-resolution satellite maps online 2015-2016 are the most user-friendly models of interactive map images from the website service. They will allow you to travel across the territory of the entire state, from anywhere in the world. Satellites make it possible to track up-to-date data on the location and condition of certain muddy objects from different settlements of vast Russia.

Satellite maps from Google are popular. This is a convenient and practical tool that allows you to view the planet at any scale. The satellite image reveals details: small streets and lanes near the house, cities, countries and continents. This was made possible thanks to satellite imagery.
Earlier to receive pictures from space shooting with a television camera with signal transmission to the station or shooting with a special photographic camera, the pictures of which were displayed on film, were used. Today, modern space technologies allow you to look at the planet thanks to the scanning mechanism embedded in the satellites.

Satellite map: application and purpose

At present, the real-time satellite world map is applied in many areas: analyzing the state of agricultural fields, forests, the ocean, and identifying the location of friends using a smartphone. For these resources, a Google satellite map is used.
The main purpose of use satellite imagery the world from Google remains navigation. The site presents a world diagram with the display of continents, states, cities, streets and tracks. This helps to orientate in the area, evaluate its landscape and simply travel the Earth without leaving home.

Quality of world map images online from satellite

The highest resolution images are available for the largest cities in Ukraine, America, Russia, Belarus, Asia, Europe and Oceania with a population of over a million people. For settlements with a smaller number of inhabitants, images are available in a limited number and of poorer quality.
Despite this, everyone can see in detail the territory of their house, nearby streets, see photos of the planet from almost anywhere. Pictures reveal placement:

  • cities, towns, villages,
  • streets, lanes
  • rivers, seas, lakes, forest zone, desert, etc.

The good quality of cartographic images allows you to examine the landscape of the selected area in detail.

Features of Google maps from the satellite:

Google satellite maps help to see in detail objects that are difficult to assess on conventional charts. Satellite images preserve the natural shape of the object, its size and colors. Ordinary, classic cards before printing and circulation, editorial work is carried out to match the scale, as a result of which the natural colors of the area and the shapes of objects are lost. Naturalness is preserved on cartographic images.
In addition, on the map you can quickly find the city of interest in any country. The diagram has a column in which in Russian you can indicate the country, city and even the house number. In a second, the chart will zoom in and display the location of the given object and those that are next to it.

Satellite world map mode

Satellite images have the ability to switch to world map mode. It helps to view the territory on the surface of the planet, to get as close as possible to the selected object, to consider the layout of the location. This mode allows you to quickly and conveniently plan a trip route, move around the city, find attractions, etc.
By specifying the house number, the chart will display its location relative to the city center in a second. It is also possible to lay a route from the initially specified object. To do this, click on the appropriate button and enter the address.

Earth map from satellite to site

the site provides users with the opportunity to use a real-time satellite map for free. For convenience, the map is divided into countries. To search for a specific city or get acquainted with the area of ​​​​the state, click on the one you are interested in and start your “travel”. The service is constantly improving, work is underway to place satellite images in high resolution small settlements.
The good quality of online satellite cartographic images posted on our website helps to quickly find the necessary object, examine the landscape, estimate distances between cities, find out the location of forests, rivers, seas and oceans. Together with Voweb, traveling around the world has become even more accessible.

For free observation of the Earth's surface and viewing satellite images online, you can use several applications. In Russia, two of them are the most popular: Google Maps and Yandex Maps. Both services boast good quality high-resolution satellite images of most countries.

Yandex maps - online application from Russian developers, therefore, the cities of Russia are more accurately worked out in it. It has built-in functionality for viewing traffic congestion data (large settlements), demographic and geodata. Google maps have no less high-quality satellite images of the territory of the Russian Federation, but data on land and traffic are available only for the United States.

Watch a map of Planet Earth from a satellite online

Below you can see the Google map embedded on the site. For more stable operation of the plugin, we recommend using the Google Chrome browser. If you see an error message, then update the specified plugin, then reload the page.

Watch Google Earth from satellite, in real time online:

Another advantage of Google Maps is the presence of a client application for working with satellite imagery. This means that access to the service can be obtained not only through a browser, but also through a previously downloaded program. It has much more opportunities for viewing and studying satellite images, working with a three-dimensional virtual globe.

3D satellite map from Google (downloadable app, not online version) allows:

  • use a quick search for the desired objects by name or coordinates;
  • take screenshots and record high quality videos;
  • work offline (preliminary synchronization via the Internet is required);
  • use a flight simulator for more convenient movement between objects;
  • save "favorite places" for quick movement between them;
  • view not only the Earth's surface, but also images of other celestial bodies (Mars, the Moon, etc.).

You can work with Google satellite maps through a client application or a browser. On the official page of the program, a plugin is available that allows you to use interactive map on any web site. It is enough to embed its address in the program code of the site. For display, you can select both the entire surface and a specific area (you will have to enter the coordinates). Management - using a computer mouse and keyboard (ctrl + mouse wheel to zoom, cursor to move) or using the icons indicated on the map ("plus" - zoom in, "minus" - zoom out, move with the cursor).

The Google Earth real-time service allows you to work with several types of maps, each of which reflects certain data on satellite images. It is convenient to switch between them “without losing progress” (the program remembers where you “were”). Available view modes:

  • satellite landscape map (geographical objects, features Earth's surface);
  • physical map(detailed satellite images of the surface, cities, streets, their names);
  • schematic geographic map for a more accurate study of surface images.

A satellite image is automatically uploaded at the point of approach, so a stable Internet connection is required to work. For work Google Planet Earth offline need to download app for Windows or other operating system. Its operation also requires the Internet, but only for the first launch, after which the program synchronizes all the necessary data (satellite images of the surface, 3D models of buildings, names of geographical and other objects), after which it will be possible to work with the received data without direct access to the Internet.
