They allow you to obtain spatial information about the earth's surface in the visible and infrared ranges of electromagnetic wavelengths. They are able to recognize passive reflected radiation from the earth's surface in the visible and near-infrared ranges. In such systems, radiation hits the corresponding sensors, which generate electrical signals depending on the intensity of the radiation.

In optical-electronic remote sensing systems, as a rule, sensors with constant line-by-line scanning are used. You can select linear, transverse and longitudinal scanning.

The total scanning angle across the route is called the viewing angle, and the corresponding value on the Earth's surface is shooting bandwidth.

Part of the data stream received from a satellite is called a scene. The schemes for cutting the stream into scenes, as well as their size for different satellites, differ.

Optical-electronic remote sensing systems carry out surveys in the optical range of electromagnetic waves.

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

Multispectral(multispectral) imaging systems produce multiple separate images over broad spectral regions ranging from visible to infrared electromagnetic radiation. The greatest practical interest at the moment is multispectral data from new generation spacecraft, including RapidEye (5 spectral zones) and WorldView-2 (8 zones).

Satellites of a new generation of high and beyond high resolution, as a rule, they shoot in panchromatic and multispectral modes.

Hyperspectral imaging 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. Thus, a filming system with 20 channels will be hyperspectral if it covers the range of 0.50-070 microns, with the width of each spectral zone not exceeding 0.01 microns, and a filming system with 20 separate channels covering the visible region of the spectrum , near, short-wave, mid- and long-wave infrared regions will be considered multispectral.

Spatial resolution- a value characterizing the size of the smallest objects distinguishable in the image. Factors influencing spatial resolution are the parameters of the optical-electronic or radar system, as well as the orbital altitude, that is, the distance from the satellite to the object being photographed. The best spatial resolution is achieved when shooting at the nadir; as you deviate from the nadir, the resolution deteriorates. Satellite images 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 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 only 64 color gradations, 8 bits/pixel - 256 gradations, 11 bits/pixel - 2048 gradations.

The evolution of maps, navigation and orientation is happening in our time. Now! The first travelers and pioneers used paper cards, maps drawn on stones, wooden planks, leather and other objects. Nowadays, few people imagine themselves without electronic navigation, satellite maps, cell phones... New technologies are coming.

Let's try to understand some of the opportunities that technology in the field of surveillance and navigation currently provides us. Let's look into history.

Creation of the first artificial Earth satellites

The idea of ​​using satellites as relays arose long before they were launched into Earth orbit. first satellite.

Withdraw for the first time aircraft Nazi Germany engineers attempted to reach the upper atmosphere by creating a guided missile “weapon of retaliation.”

The Nazis did not achieve their goals, but they attracted the attention of many specialists to the development of missile weapons. People began to think about the possibilities of using guided missiles for scientific purposes.

One of the British army officers, science fiction writer Arthur C. Clarke, published an article in Wireless World magazine in 1945, where he proposed the principle of satellite communications and the possibility of turning such missiles into “unearthly repeaters.”

On June 26, 1954, Korolev presented a memo to the Minister of Defense Industry Dmitry Ustinov: “ About the artificial satellite of the Earth».

Work has begun on the AES project.

October 4, 1957 at 10:28 p.m. Moscow time, Sputnik 1 was launched into orbit. It began sending its first signals from space immediately after separating from the last stage of the rocket. It was a metal ball half a meter in diameter with a simple radio transmitter.

In 1967, the Russian satellite TV system “ORBITA” began operating. It allowed the transmission of one Central Television program through an artificial Earth satellite: Channel One.

Real-time satellite maps
The discovery of space began with interactive maps— photographs of the Earth received from a satellite. This significant event occurred on August 17, 1959, thanks to the American artificial satellite Explorer 6. The era of satellite photography has begun.
Let's focus on services that have open access.

If someone is content with satellite maps in real time, then there were those for whom this seemed not enough. Employees of the interactive systems studio from the Georgia Institute of Technology went further and proposed real-time planet observation project in 3D view.

Depending on the time of day, you can see either a very high-quality broadcast or a dark screen. If the second option, then you just need to try again later, since everything depends on the location of the satellite at the moment.

Planet Earth in real time online

Also, services such as Google Maps have appeared, which remain the most accessible resource for the average person.

(To move around the map, zoom in, out of the map, change the image angle, use the navigation in the form of arrows and + and – signs at the top of the map. Also try to control the map by holding the right mouse button)

You can view world maps and satellite photos, determine the coordinates of any point on the Planet, measure distances between objects, calculate the area and plot a route using new satellite maps.

(The map can be enlarged or reduced)

If Google Maps provides static information, that is, satellite images are not shown in real time, then there are devices that provide this opportunity.
For example, using the Baikal satellite receiver you can receive photos and satellite maps in real time.

The Baikal satellite weather receiver is designed to receive images of the earth's surface from weather satellites located in low-earth and geostationary orbits, operating in the frequency range 137-138 MHz with frequency modulation of the signal in APT (NOAA15, NOAA17, NOAA18, NOAA19) and WEFAX (METEOSAT7, GOES). The receiver can be installed both on stationary and mobile objects, for example on a boat, yacht, sea or river vessel, icebreaker or car. Image reception is possible even while moving.

Services, facilities, discoveries...

With the help of Google Maps and other platforms, enthusiasts are coming up with more and more new services:

Several startups are developing services similar to projects from Google. One of them is the American company SkyBox, which launches satellites into space. The goal is to make real-time Earth observation more accessible. The company demonstrated its vision for the future project with a video showing China's Capital International Airport, filmed by the Skybox satellite.

Currently there is one satellite in orbit. A total of 24 satellites are planned to be launched to cover the entire planet. The satellite weighs only 120 kilograms and its size is 60*60*90 centimeters. Shooting detail is up to 90 centimeters per pixel.

To develop this system, navigation systems, satellite repeaters, web cameras, services such as - Google Earth and Microsoft Virtual Earth.

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 alleys near the house, cities, countries and continents. This became possible thanks to satellite imagery.
Earlier to receive pictures from space filming was used with a television camera with a signal transmitted to the station or filming with a special photographic camera, the images of which were displayed on film. Today, modern space technologies make it possible to look at the planet thanks to the scanning mechanism built into satellites.

Satellite Map: Applications and Purposes

Currently, real-time satellite world map is used in many fields: analyzing the state of agricultural fields, forests, oceans and identifying the location of friends using a smartphone. Google satellite map is used for these resources.
Main purpose of use satellite images the world navigation remains from Google. The website features a world diagram showing continents, states, cities, streets and highways. This helps you navigate the area, appreciate its landscape, and simply travel around the Earth without leaving your home.

Quality of online world map images 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 more than a million people. For settlements With fewer residents, images are available in limited quantities and of poorer quality.
Despite this, everyone can take a detailed look at the territory of their home, nearby streets, and look at photos of the planet from almost any point. The pictures reveal the placement:

• cities, towns, villages,
• streets, alleys
• rivers, seas, lakes, forest zones, deserts, etc.

Good quality cartographic images allow you to examine the landscape of the selected area in detail.

Google map capabilities from satellite:

Satellite google maps help to examine in detail objects that are difficult to evaluate on conventional diagrams. Satellite images preserve the natural shape of an object, its size and colors. Regular, classic cards Before printing and circulation, they undergo editorial elaboration to match the scale, as a result of which the natural colors of the area and the shapes of objects are lost. The cartographic images retain their naturalness.
In addition, you can quickly find the city of interest in any country on the map. The diagram has a column in which you can indicate the country, city, and even house number in Russian. In a second, the diagram will zoom in and display the location of the given object and those located 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, get as close as possible to the selected object, and consider the layout of the location. This mode allows you to quickly and conveniently plan your trip route, move around the city, find attractions, etc.
By specifying the house number, the diagram will display its location relative to the city center in a second. It is also possible to plot a route from the initially specified object. To do this, click on the appropriate button and enter the address.

Map of the earth from satellite to website

the site allows users to use a satellite map in real time completely free of charge. 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 begin your “travel”. The service is constantly improving, work is underway to post high-resolution satellite images of small settlements.
Good quality of online satellite cartographic images posted on our website helps you quickly find necessary object, examine the landscape, estimate the distances between cities, find out the location of forests, rivers, seas and oceans. With Voweb, traveling around the world has become even more accessible.

Google Map is one of the most popular services today. It provides users with the opportunity to observe our planet (and not only) from a satellite online in high quality and in real time (sights of the planet in). At some point, the primacy of the schematic view of maps was taken over by the application “ Open Street Maps". Where everyone in the know can edit a map in Wikipedia style, but this does not change anything and today Google Maps is the most popular online map service. The popularity of cards from this company has been in first place for many years due to good quality satellite images in any corner of the planet, even Yandex could not provide such quality in its homeland.

Quality of Google Maps satellite images in 2020

Google continues to improve its brainchild in the form of visualization of our planet, improving the quality and detail of surfaces. More recently, the company has improved its services using new satellite Landsat 8, which can photograph the surface of planet Earth with a resolution of 15/30/100 meters per elementary point. The database of satellite images in real time was previously updated only in 2013. At that time, the application used images taken by the Landsat 7 satellite, which was also known for introducing some bugs and glitches into the maps. To compare the quality of images taken by different satellites, pay attention to the screenshot below.

Images taken by different satellites

In the examples given on the screen you can see that the image of the new satellite shows not only improved detail of earthly objects, but also more natural colors. Representatives of Google announced that about 700 trillion pixels of graphic data were spent on assembling a mosaic of the earth's surface of a new generation. Almost 43 thousand powerful computing machines in the Google cloud worked for a week on gluing together pictures.

How to use Google Maps online

Anywhere in the world you can use Google Maps online in high quality using a tablet, mobile phone or computer. Just follow the link https://google.com/maps/ or use the embedded map below and you can find the country, city and even the road to the museum by indicating required parameters search. And for mobile devices you can download a special application that is more convenient to use.

To find the way to a laundromat or a cafe that you often visit, simply enter the addresses in the program line and you will no longer need to enter this data every time. At the same time, you can not only view the route to the establishment, but also get acquainted with information that relates to this establishment, for example, opening hours, contact details, etc.

Amazing Facts About Google Maps

Features and benefits of online maps in real time

From the first days Google Maps became a revelation for all users. They made it possible to look at cards in a new way, to pay new attention to this tool in general. Everyone who accessed the Internet back in 2005 sought to immediately take advantage of online maps and see your city or country from a satellite.

It seems unthinkable, but today it is possible to view other planets solar system V Google app Maps!

Planets in Google Maps

To do this, go to the web version of the program and zoom out the Earth image with the mouse wheel to the maximum. Other planets will appear in the block on the left that you can select to view. There are all the planets of the solar system and several additional satellites. For example, Callisto is a satellite of Jupiter. True, the photographs do not allow us to look at other planets as closely and in detail as happens with the Earth.

Google Maps from satellite in 2019 will allow you to view the surface of the earth and populated areas in excellent quality, which cannot be done using a regular map. When drawing up paper and other versions of maps, natural colors, clear contours of the banks of rivers, lakes, colors of areas of the earth and other color schemes are omitted, which is why we have poor orientation. Having looked at a desert area on a regular map, one can only guess what kind of vegetation or relief there is. By accessing Google Maps in real time, you can even see the color and shape of the fence at any address on another continent.

5 strange places that can be seen on Google Maps

Satellite map of Russia - high-resolution images taken from space by orbital stations. The image that the user sees consists of many individual images. The high quality of equipment used at orbital stations made it possible to achieve the highest quality of imaging. As a result, on the screens of mobile devices and PC monitors, we have access to high-precision, high-resolution images, the image of which is very accurate and clear.

The satellite map of Russia displays high-resolution images in real time. 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, you will be able to view streets, buildings, individual structures and squares. The larger the city, the more detailed the satellite map section will be for it.
