Three-dimensional terrain model in GIS "panorama"

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, the screens mobile devices, PC monitors, high-precision images are available to us high resolution, 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 state of certain objects from different settlements boundless Russia.

Three-dimensional terrain model in GIS "Panorama"

A three-dimensional terrain model in the GIS "Panorama" is a surface built taking into account the terrain, on which an image of a vector, raster or matrix map can be superimposed, and three-dimensional objects located on it, corresponding to the objects of a two-dimensional map. It is a full-fledged 3D map that allows you to select objects on the model in order to request information about the object, edit their appearance and characteristics. On the 3D model, both surface and underground objects can be seen.

Creating a 3D model

Creation of a three-dimensional model does not require long-term preparation, it is enough to have a two-dimensional map and a matrix of heights. Based on these data, it is possible to build a three-dimensional relief model of the selected area. To build a three-dimensional model, taking into account the objects located on this map, a library of three-dimensional images of objects is needed, which is added to the classifier of any map.

Together with the classifiers of electronic vector maps, libraries of three-dimensional images for various scales are supplied. To obtain a three-dimensional view of the available electronic maps, it is enough to connect one or several libraries to the classifier and assign a suitable image to the selected objects. If you need a more detailed and individual display of objects, you can create your own volumetric images using Legend editor .

Building a 3D Model

To build a three-dimensional terrain model, the following can be used: a vector map, a matrix of heights, a triangulation terrain model (TIN-model), a map classifier, a library of three-dimensional images of objects, digital photographs of the terrain, and digital photos terrain objects. The composition of the initial data can be different and depends on what type of model you need to get.

Types of 3D terrain models

Typical three-dimensional models are created according to city plans, topographic maps or overview maps. Typical models contain terrain surface, buildings, road network objects, pipelines, wells, traffic lights, vegetation objects, hydrography and other objects of a simple shape.

Building a generic model is the most fast way obtaining a high-quality three-dimensional terrain model. Generic models can be used for visual evaluation relative position objects, taking into account the features of the relief and their height (Figure 1.1), analysis of the relative position of cables of power networks and pipelines for various purposes (Figure 1.2).

1. 3D detail view models

3D detailed view models describe terrain with customizable features and are created from city plans. Detailed view models contain the surface of the terrain, typical objects and objects, the three-dimensional image of which approaches their real appearance on the ground (architectural structures with entrances, pipes, lift towers, design elements, etc.).

You can use the texture setting to customize the detailed view models of individual objects. appearance through the semantic characteristics of these objects.

In the editor of the three-dimensional view of GIS "Panorama" objects, importing signs from the VRML format is available, so some elements of an individual view of objects can be created in three-dimensional editors of third-party developers and loaded into various templates for displaying these objects.

2. Three-dimensional models of the interior

Three-dimensional models of interior spaces allow you to describe the three-dimensional view of the interior and are created on the basis of floor plans (Figure 1.5).

When displaying three-dimensional models of interior spaces, individual objects and entire interiors can also be used, created in various programs for editing three-dimensional images in VRML format and imported into the library of three-dimensional images of the GIS "Panorama" vector map classifier.

3. Thematic models

Thematic models are created from thematic maps and are used to design statistical diagrams. One example of using the technology of building a thematic model can be the creation of a three-dimensional terrain model based on a map of the operational situation (Figure 1.8). Models imported from VRML format and used to symbolically display map objects fit perfectly into the setting of a thematic map.

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 the 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 technology allows 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 more than 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:

Satellite google maps help to examine in detail objects that are difficult to assess on conventional diagrams. Satellite images preserve the natural shape of the object, its size and colors. Ordinary, classic maps before printing and circulation undergo editorial study 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 sights, 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 allows users to use satellite map in real time absolutely 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 high-resolution satellite images of small settlements.
The good quality of the online satellite mapping images posted on our website helps to quickly find necessary object, examine the landscape, estimate the 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.

Excellent rendering in 3D largest cities Europe. In my opinion, it was done better than Google's.
It is not clear why they removed the already finished material? We can only guess:

1. sold to Google or someone else,
2. gave development and is still in working order,
3. could not automate the process and do not have time to update.

Google Maps in Russia

Not so long ago, parts of cities such as Moscow and St. Petersburg were drawn in 3D on maps.
And in many, even small towns, one or more skyscrapers in the center were drawn. Why Google abandoned this is not clear.

Bing Maps Bing Maps also has a 3D feature.
You will also need to install a plugin.
Cons - nothing better Google Maps and does not work with all browsers.
That is, another promotion of Internet Explorer.

Google Maps Essentially, this is a program Google Earth built into Google Maps.
In order to use this effect, you need to switch to photography mode and the 3D button will appear below the compass. The terrain is very well implemented in volume: mountains, valleys...
As for the cities, they remained flat, although the whole picture is tilted. The real 3D effect up to the trees have only big cities Western world (Europe, Australia, Canada) and most of USA. For circular rotation, you need to hold down the Ctrl or Shift button and use the mouse.

Google Maps 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 at high quality and in real time (the sights of the planet in). At some point, after all, the championship of the schematic map view was intercepted by the Open Street Maps application. Where everyone in the know can edit a Wikipedia-style map, but this does not change anything, and today Google Maps is the most popular online map service. The popularity of the cards of this company is in the first place long years due to good quality satellite images in any corner of the planet, even Yandex could not provide such quality in its homeland.

Google Maps Online

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 the new Landsat 8 satellite, which can photograph the surface of the planet Earth with a resolution of 15/30/100 meters per elementary point. The real-time satellite imagery database was only updated in 2013 before. At that time, the application used images taken by the Landsat 7 satellite, which is also known for introducing some bugs and crashes into the maps. To compare the quality of images taken by different satellites, pay attention to the screen below.

Images taken by different satellites

In the examples on the screen, you can see that the image of the new satellite shows not only improved detail of terrestrial objects, but also more natural colors. Google representatives announced that about 700 trillion pixels of graphic data have been spent on collecting a new generation of mosaics of the earth's surface. Almost 43 thousand of the most powerful computers in the Google cloud worked for a week on gluing 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 built-in map below and you can find the country, city and even the way to the museum by specifying the desired search parameters. And for mobile devices, you can download a special application that is more convenient to use.

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

Let's use an example to use a map from Google from satellite 2018.

1. Go to the website or open the app on your mobile device.
2. You just need to point with the cursor or touch on the touch screen, and you can view the details of this site.
3. In order to find out the distance between cities, right-click on one of them and select "Measure distance" from the drop-down menu. Now the second point can be specified with the left mouse button. If necessary, the point can be dragged with the mouse to another location, the distance information will be updated.
4. To select the mode "Relief", "Bike paths", "Traffic jams" - select the menu sign (three bars) and press the desired option. If you are using Apple devices, click on the diamond icon with the layer and also on the desired option.
5. To take advantage high quality images in 3D, click on the quadrangle in the lower left corner. It will say "Satellite", if you need to return to map mode, press it again.
6. To select Street View, drag yellow man to the desired area of ​​the map, or simply enter the exact location in the query string, preferably with a home address.
7. High-resolution Google Maps allows you to view streets in historical mode, i.e. how they have changed over time. To do this, throw the little man on Right place cards. Select the clock icon and move the time slider to select the desired date.

Surprising Facts About Google Maps

Features and benefits of online maps in real time

From the first days of Google Maps have become a discovery for all users. They made it possible to look at the cards in a new way, to pay attention to this instrument in a new way. Everyone who accessed the Internet back in 2005 sought to immediately use online cards and see your city or country from a satellite.

It seems unthinkable, but today there is an opportunity to view other planets solar system in the Google Maps app!

Planets in Google Maps

To do this, go to the web version of the program and move the image of the Earth to the maximum with the mouse wheel. Other planets will appear on the left in the block, which you can select to view. There are all the planets of the solar system and a few more of their satellites. For example, Callisto is a moon of Jupiter. True, the pictures do not allow us to view other planets as closely and in detail as it happens with the Earth.

Google maps from satellite in 2018 will allow you to view the surface of the earth and settlements in excellent quality, which cannot be done using a regular map. When compiling paper and other versions of maps, natural colors, clear contours of the banks of rivers, lakes, coloring of land areas and other color schemes are omitted, which is why we have poor orientation. Looking through the desert regular map one can only guess what kind of vegetation or relief is there. Turning to Google Maps in real time, you can even see the color and shape of the fence at any address on another continent.
