High-resolution satellite imagery. Map of the Finders from the satellite - streets and houses online. Google Maps - High Definition Satellite View

The evolution of maps, navigation and orienteering is taking place in our time. Now! The first travelers and pioneers used paper maps, cards drawn on stones, wooden plates, leather and other objects. Currently, few people imagine themselves without electronic navigation, satellite maps, cellular ... New technologies are coming.

Let's try to understand some of the possibilities that technology provides us in the field of observation and navigation at the present time. Let's look at history.

Creation of the first artificial earth satellites

The idea to use satellites as repeaters originated long before they were launched into Earth's orbit. first satellite.

For the first time, engineers of fascist Germany tried to bring aircraft into the upper atmosphere by creating a guided missile "weapon of retaliation."

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

One of the officers of the British army, science fiction writer Arthur Clarke, in 1945 published an article in the magazine "Wireless World", 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 memorandum to the Minister of Defense Industry Dmitry Ustinov “ About an artificial satellite of the Earth».

Work has begun on the AES project.

October 4, 1957 at 22 h 28 min. Moscow time "Sputnik-1" was launched into orbit. He began to send the first signals from space immediately after separation 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 to operate. It made it possible to broadcast one program of the Central Television through an artificial earth satellite: Channel One.

Satellite maps in real time
The discovery of space began with interactive maps - photographs of the Earth obtained from a satellite. This significant event took place on August 17, 1959, thanks to the American artificial satellite "Explorer 6". The era of satellite photography has begun.
Let's dwell on the services that have open access.

If someone is content with satellite maps in real time, then there were those for whom it seemed a little. Employees of the studio of interactive systems from the "Georgia Institute of Technology" went further and suggested real-time planetary observation project in a three-dimensional view.

Depending on the time of day, you may see either a very high quality broadcast or a dark screen. If the second option, then you just need to try again later, since it all 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 man in the street.

(To move around the map, zoom in, zoom out, change the image angle, use the navigation in the form of arrows and signs + and - at the top of the map. Try also, 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 such an opportunity.
For example, using the Baikal satellite receiver, you can receive photos and satellite maps in real time.

Satellite weather receiver "Baikal" is designed to receive images the earth's surface from meteorological satellites in low-orbit 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) modes. The receiver can be installed both on stationary and on mobile objects, for example, on a boat, yacht, sea or river vessel, icebreaker or car. Reception of a picture is possible even while driving.

Services, services, discoveries ...

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

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

At the moment, one satellite is operating in orbit. A total of 24 satellites are planned to be launched to cover the entire planet. The satellite weighs only 120 kilograms and measures 60 * 60 * 90 centimeters. Shooting detail - up to 90 centimeters per pixel.

For the development of this system, navigation systems, satellite repeaters, web cameras, services such as Google Earth and Microsoft Virtual Earth will be used.

Content

All people know about the beauty of the planet Earth, but earlier only astronauts had a chance to make sure of this. Now this opportunity is available to every computer user with Internet access. Real-time satellite view is broadcast on many sites that are easy to find through Google, viewing is completely free.

Where to see real-time satellite view

For those looking for options on how to view the Earth from a satellite in real time, there are several options. The first of these offers a video feed from the ISS (International Space Station), on which one of the teams fixed a camera directed towards the planet. You won't be able to see the entire globe from the station online (the image captures only a part), but fantastic sunsets and sunrises are guaranteed. In the second option, you can study a specific area using images from space in several formats (cartographic, satellite).

Earth from space online in real time

Planet Earth from the satellite is broadcast live with a delay of one or two minutes around the clock. If you do not see anything when you go to the site, it means that the observation is being filmed from the dark side of the planet (where night has fallen at the moment). Those looking for a real-time satellite view of the Earth should visit ustream.tv/channel/live-iss-stream. This is the official NASA live stream, which can be found on many other resources, but this service is the original source.

There you can also find the station's flight schedule, find out at what moment it flies over Russia. Sometimes, together with the ISS staff, a program is drawn up, according to which they go on video communication. They communicate, show and talk about interesting facts in space. The earth from the satellite in real time and communication with the staff takes place online every day.

Real-time satellite maps

The view of Earth from space does not have to be in video format. Satellites flying in orbit are capable of making daily great amount photos, which are then used to compile maps of the area. The pictures are so detailed that each person can find not only their city, but also their own home. Several companies are engaged in collecting data about the Earth from satellite, which then offer their data.

An example is the site meteosputnik.ru. This project uploads photos from low-orbit metrological geostationary stations of the planet to the network. The service implements reception of images that are received in real time. They are laid out immediately after the end of the data transfer. The site offers for viewing two formats of photos of the Earth: HRPT and ART. They differ among themselves in the resolution and the range of the obtained images.

Google planet earth online

One of the most popular plug-ins for viewing images of the Earth is the plug-in from Google "Google Earth". It is installed on a computer and provides an opportunity to view and even "visit" the most remote corners of the planet. The service offers, if you wish, to go on a virtual "flight" around the globe... You can use standard GPS coordinates to move, in addition to the plug-in, images of other planets that were taken at the stations are provided.

Yandex maps

The direct competitor of the American giant is the Russian company Yandex, which does not offer to watch from a satellite in real time, but provides maps of no less quality. In order to view the images, you need to go to the main page of the service and click on the "Maps" tab. All accessible points of the globe that you can zoom in and examine in detail will open before you.

Every user at least once wondered how to find their home using aerial photographs.

Surprisingly, Internet access to this information is now completely free.

With the launch of commercial Earth observation, Internet tools are now available to us that make it easy to see your home from space.

In our modern space age, there are more than 8,000 satellites that are constantly orbiting the Earth.

The vast majority of them receive data and transmit encoded.

Many of them are equipped with high power cameras. Just look up into the sky and you will definitely see the satellite's trail after the satellite flies overhead.

But how can you access this satellite data and aerial photographs of your home?

Satellite images of the entire Earth

If you just want to see satellite images of the entire planet, you have some simple solutions.

You can go to the site of NASA forecasters. Every three hours, images taken by the NOAA Geostationary Operational Environmental Satellite are posted on the site.

This is the release of images of the entire hemisphere of the planet Earth.

From these pictures you can see the main changes weather conditions affecting different hemispheres of the Earth.

The images are so accurate that you can see a specific location on Earth as close as possible.

The maximum realism is striking in these photographs. The weather changes you see in these pictures are happening on the planet right now.

If you don't want to watch videos, but just want to enjoy the extraordinary hemispheres of the Earth, these are the pictures you need.

Also on the Internet you can find amazing new satellite images of the Earth, which come from the Meteosat spacecraft of the 3rd generation of the European Space Agency.

Approximation. Looking at satellite images of houses

If these photos from weather satellites it won't be enough for you, let's see how to zoom in close enough to see houses from space.

To do this, we need the best tool on the market today, in my opinion. All you need is a web browser and internet connection.

On first launch, the user gets a satellite view over North America.

You can then zoom in or move the camera across the surface to see any location on Earth.

You can also enter the exact address you want to see.

Once you do this, you will have free access to satellite images of the house you provided. You can save the image or print it.

Another interesting tool is Google Earth. It can be accessed via the link: http://earth.google.com.

The main difference between Google Maps and Google Earth is that you have to download and install the corresponding application on your local computer (they have a version for PC, Mac, Linux and even iPhone).

Once you have downloaded and installed, you can see a 3D view of the Earth that you can zoom in and out.

You can also rotate the 3D model of our planet. You can enter your address and look at your house from above.

Google Earth's print function works much better than Google Maps because it uses a printer to print directly instead of using a web browser.

There are those among modern users who choose not to use the products of this search engine leader, suspecting that the company's technical engineers are spying on them.

Microsoft's service used to be called MSN Maps, now the developers have changed the name to Bing maps by completely updating the interface and functionality.

Yahoo's service is called Yahoo Maps and is very similar to Google Maps.

There is a big difference between the two.

You can find a cool app on the internet that allows you to see both of these apps side by side.

Comparing them, one can understand that the latter have been worked out in more detail.

And most cities are best viewed through this application.

Where do all these photos come from?

Google Maps and other popular mapping services are really just clients.

They just like the users use satellite services that actually download these photos from space.

There are several major service providers in the market, including Geoeye.

Geoeye's main competitors are Digitalglobe and Spot Image.

Each company has a fleet of satellites that they use to observe the Earth.

Their technical capabilities make it possible to photograph tiny Earth objects.

The smallest object that has been captured so far is approximately 45 cm (18 inches).

In other words, a 45cm object will appear as one pixel in a photograph.

Private satellites that monitor our planet around the clock:

• GeoEye - 5 satellites: IKONOS, OrbView-2, OrbView-3, GeoEye-1, GeoEye-2 (in 2013).
• DigitalGlobe - 4 satellites: Early Bird 1, Quickbird, WorldView-1, Worldview-2
• Spot Image - 2 satellites: Spot 4, Spot 5

Each of these services allows customers to purchase satellite imagery directly, but the prices are extremely high: hundreds or even thousands of dollars for specific satellite imagery.

It is usually not possible to buy photos directly from the company that owns the satellite.

Most often, in such cases, they use the services of international intermediaries.

Average users are better off sticking to free sources.

When you look at these amazing images from space, you may be amazed at the accuracy and detail. In fact, this is far from the most relevant data.

At the moment, in the public domain, you can find pictures from two years ago.

More relevant data are bought out by special services, intelligence organizations and are never freely available.

But, if you have a thirst for up-to-date information, you should turn to other sources that will give you a lively view of the Earth from space.

For example, you can access live streaming from International space station NASA.

About 40% of the time, if you go to their website, you will be able to see video of the Earth from the space station.

Another service called Urthecast launched a high-definition camera feed from the International Space Station in 2013 to broadcast video of Earth from space.

Navigation

Google Maps is not just a popular program used by the company, but it is also one of the most popular maps used for hybrid web applications.

This makes Google Maps a very popular and versatile tool that is used in a variety of ways.

It is used in localization applications, in weather forecasting services.

Learning to use the app is easy. This will help you navigate the various map-based hybrid web apps.

Although some of these hybrids change some of the default settings.

But knowing Google Maps will allow you to quickly adapt to small changes in programmatic mapping.

Tip: While reading the instructions for using the app, try moving the maps to a separate browser window. You will be able to practice in parallel while reading useful tips.

Drag and Drop Control

The easiest way to navigate is using the drag and drop technique.

To do this, move the mouse cursor to the required areas of the map while holding down the left mouse button.

Simply move the clamped section in the direction you want it to rotate.

For example, if you want the map to move south, hold down the mouse button and move the mouse up.

The image will move to the north, thus revealing all maps to the south.

You can also center the map. You can click on the site that interests you and drag it towards the center.

Or, you can double click on the area. This will not only center the area you want, but also bring the image closer by one division.

To zoom in and out with the mouse, you can use the mouse wheel, which is located between the two buttons.

By moving the wheel, you change the scale. If you don't have a mouse wheel, you can zoom in and out on the map using the navigation icons on the left side of Google Maps.

Understanding google map menus

There are several buttons at the top of the Google map that change modes.

To understand that these buttons work, we'll take a quick look at each of them.

Map... This button changes the appearance of the cards to the original parameter. This view is similar to a regular map.

It has a gray background. Small roads will be white, major roads yellow, and major highways and highways orange.

Satellite... This button draws Google Maps with a satellite overlay that allows you to see the area from above.

In this mode, you can zoom in until you can see individual houses.

Terrain... This button highlights the differences on the ground.

It can be used to define flat or rocky terrain.

It can also give an interesting view when zooming in highlands.

These buttons are responsible for making the cards interact with the user:

Traffic jams... This button is very convenient for those who are often late due to slow moving traffic.

This view is designed to be scaled to street level so you can see where and what the traffic is.

Roads on which vehicles move freely are marked in green, while roads where traffic is difficult will be highlighted in red.

Street view... This is a very interesting and even fun way to use the cards, this is the most difficult mode.

This view displays the street as if you were standing in the center.

This is accomplished by zooming in at street level and then using drag and drop. The user feels like a small person at the center of what is happening.

Please note that this display option will only work on streets that are highlighted in blue.

Menu navigation

You can also use the navigation menu on the left to manipulate the map. This provides an alternative to using drag-and-drop menus.

There are four arrows at the top of this menu, one in each direction.

By clicking on the arrow, you move the map in that direction. By clicking on the button between these arrows, you will be centered by default.

Below these arrows are the plus and minus signs.

These buttons allow you to zoom in and out. You can enlarge it by clicking on the plus sign and zoom out by clicking on the minus sign.

You can also click on a part of the train track to increase the level.

Google Maps Keyboard Shortcuts

Google Maps can also be moved using a keyboard shortcut.

To move north, use the up arrow key.

To move south, use the down arrow key.

To move west, use the LEFT ARROW KEY.

To move east, use the right arrow key.

Use the plus key to increase. To zoom out, use the minus key.

Navigating the maps is simple and very addictive. It is thanks to him that the user can look at our land with completely new eyes.

They allow obtaining spatial information about the earth's surface in the visible and infrared ranges of electromagnetic wavelengths. They are capable of detecting passive reflected radiation from the earth's surface in the visible and near infrared ranges. In such systems, the radiation hits the appropriate sensors that generate electrical signals depending on the intensity of the radiation.

In optoelectronic remote sensing systems, as a rule, sensors with continuous line-by-line scanning are used. Can be distinguished linear, transverse and longitudinal scanning.

The total scan angle across the route is called the angle of view, and the corresponding value on the surface of the Earth is bandwidth.

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

Optical-electronic ERS 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), therefore they are black and white.

Multispectral(multispectral) imaging systems generate multiple individual images for broad spectral areas ranging from visible to infrared electromagnetic radiation. At present, multispectral data from new-generation spacecraft, including RapidEye (5 spectral zones) and WorldView-2 (8 zones), are of the greatest practical interest.

New generation satellites of high and ultra-high resolution, as a rule, survey 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. So, a survey system with 20 channels will be hyperspectral if it covers the range of 0.50-070 microns, while the width of each spectral zone is not more than 0.01 microns, and a survey system with 20 separate channels covering the visible region of the spectrum , near, shortwave, mid and far 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 orbital altitude, that is, the distance from the satellite to the object being surveyed. The best spatial resolution is obtained when shooting in nadir, while deviating from nadir the resolution deteriorates. Space images can be of low (over 10 m), medium (10 to 2.5 m), high (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 in 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.
