Fresh satellite maps 09.2017. Satellite map of the world online from Google. High quality satellite map

What are Google Maps? It is a service that consists of several applications provided free of charge and includes the mapping site Google Maps and a route planning program (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 of interesting places, unusual architectural sights, stadiums, and anthropogenic formations began to be freely available.

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 The first version for mobile phones appeared in 2007, and the second version appeared in 2007. 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 In 2007, the corporation announced that it was providing mapping services to more than 150 million customers.

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

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 of 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. The larger the size of the city, the more detailed the section of the satellite map will be 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 of different sizes at a specific 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.

Google Maps Service (Google Maps) is one of the most powerful mapping services in the world. Its capabilities allow you to enjoy satellite images of the surface of our planet. You can also use the capabilities of an interactive map, easily build a convenient route from point A to point B, get up-to-date information about traffic jams, and much more. At the same time, not all users are fully familiar with the capabilities of this service, which in a certain way prevents its full use. This material is designed to eliminate such "white spots", in which I will talk about Google maps, which are available online in real time and in excellent quality, and explain in detail how to use their capabilities.

We study the functionality of the online service "Google Maps"

Capabilities of the map service Google Maps

"Google Maps" is a web service that provides detailed visual information about geographic regions and places around the world. In addition to displaying a conventional road map, the service also offers aerial and satellite imagery of various locations, and there are images taken from various vehicles.


 This is what the Google Maps start screen looks like.

Google Map includes several popular services:

  • The route planner offers the creation of routes for drivers and pedestrians who want to get from point A to point B;
  • The Google Maps API makes it possible to embed maps from Google maps on various sites;
  • Google Street View (Google StreetView) allows users to view the streets of various cities of the world, virtually moving through them;
  • Google Maps for mobile platforms offers the use of GPS navigation of mobile devices to position the user on the map;
  • Auxiliary services offer images of the Moon, Mars, clouds, and so on. for astronomers and just amateurs.

To start working with Google maps in full screen, launch the service google.com/maps. You will see a schematic map of the world (depending on the user's location, usually a map of Europe).

Instructions for using the map from Google

The Google Maps service interface looks like this:


Additional options in the Menu item

Also in the Google Maps menu bar, which opens by pressing the menu button at the top left, the following useful options are presented:

  • « Satellite» - Switches to photographic map display mode, created using satellite photos. Pressing this option again switches the map back to schematic mode;
  • « Traffic jams» - shows current traffic jams in major cities. The color gradation from green to red shows the speed of traffic in the specified traffic jams;
  • « Transport» - allows you to display the schematics of public transport in the right place;
  • « Relief» – allows you to display the terrain of the area
  • « Transfer of geodata» - allows people to follow the location of each other using Google Maps;
  • « My places» - allows you to move between the places you added in the Google Maps service;
  • « Your impressions» - allows you to add some textual impression about any of the places on the map (as well as attach a photo of this place).

Activate Google Maps Satellite View

Displaying Google maps using satellite photos is one of the most popular forms of working with the Google Maps service. It allows you to enjoy the view of the desired geographical location, created using satellite images, as well as images from special devices operating at a bird's eye view (from 240 to 460 meters).

The received photographs are regularly updated (their age is no more than 3 years). They enable each user to enjoy the view of the desired places from the satellite, visually pave the most convenient road from one place to another, and so on.


Google Earth - allows you to enjoy high-resolution images

Among the features of the Google Maps service is the Google Earth service. In addition to the technology of the already well-known satellite mapping of the surface of the globe, Google Earth allows you to view 3D images of many colorful places, while photos of some famous tourist sites have the highest resolution.

A feature of this service is also two, in our opinion, the main functions:


Conclusion

The Google Maps service (Google Maps) allows you to both view satellite maps in real time for free, and use various forms of navigation to plot a user-friendly route. At the same time, Google Maps competitors - Yandex.Maps, Bing Maps, Apple Maps and other analogues are generally inferior to Google maps both in terms of coverage and in general functionality. Therefore, we recommend using Google maps to search and visually view the geographical object you need.

The satellite map of the world allows you to quickly move around the planet between any settlements. Detailed satellite map of the world in Russian:


Examine the schematic map or switch to the world map from the satellite in the lower left corner of the map. Schematic map of the world is a map of the countries of the world and cities with street names and house numbers in Russian. On a schematic map of the world, sights and tourist sites are indicated, the location of railway stations, shops, restaurants and shopping centers, a map of the city's roads. Satellite map of the world will allow you to view satellite photos of the city thanks to images from the Google Maps service.

You can zoom in on the online map, scaling it to street and house numbers. To change the scale, use the "+" (zoom in) and "-" (zoom out) icons located in the lower right corner of the map. You can also zoom in or out on the map using the mouse wheel. Left mouse button zooms in on the map, right mouse button zooms out. The mouse can move the interactive map in all directions by grabbing the left mouse button to any place on the map.

Interactive world map online is a very convenient and modern guide for exploring the city, its districts and attractions, hotels, places of recreation and entertainment. An online world map can become an indispensable tool for you in independent travel. Interactive map provided by Google Maps.

How satellite maps of the world are created:

The satellite, passing over the planet, scans the earth's surface and maps are compiled using software. More recently, several years ago, satellite maps showed the surface of the planet from a height of several kilometers. Now technologies allow making satellite maps from a height of several meters, and in the near future technologies will allow creating satellite maps with details up to 30 centimeters.

What to see on a world map from a satellite:

First of all, people look on the map for their country, their hometown, the street and the house in which they live. To do this, you can zoom in on a schematic map of the world to your city, and then turn on the "Satellite" mode in the lower left corner of the map. In the same way, you can travel around the world online, exploring the sights of countries and cities in real time. Popular places that are often searched for on the satellite map: Reichstag in Berlin (Germany), Acropolis of Athens in Greece, Egyptian pyramids, Italy - Colosseum in Rome (Ancient Roman arena of gladiator fights, Peterhof in Russia (west of St. Petersburg), Statue of Liberty in the USA - a symbol of America, the Eiffel Tower in Paris (France), the Great Wall of China.

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. 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 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.
