I believe you will be amazed at this wonderful software after you have used it. Google's latest software called "Google Earth" allows you to browse the world. You can not only observe every corner of the world at will, but more importantly, it can give you a brand-new feeling, that is, how you will look at the world around you in the near future. Come with me to experience it!

And please be sure to maintain smooth internet access conditions. After the installation is successful, the "Google Earth" icon will appear on the desktop.

2. Try your hand for the first time

Let's see what it can do first. With this software, global geographic information can be seen in front of you by using pictures and maps provided by satellites and powerful Google search technology. Not only can you roam in space, but you can even see the eaves of your home; Find the destination directly and observe from any angle. Search schools, parks, restaurants, hotels and driving guides. Let's open it quickly and have a look.

(1) Start your first trip

When the software is opened, it will automatically connect with the server. When you see our beautiful earth approaching you, it means you have succeeded. This smooth gradient is really like the advance of the lens in the movie, and this feeling is the most appreciated place of the software.

This English software may have stumped many friends, so don't worry. Let's start our first trip with the most primitive method. Select the left part of the software "Fly to" and enter "39d54'16.68"n,163d23'29.52"e" in the box below. You should be able to see that this is a geographical coordinate, that is, 39 degrees 54 minutes 16.68 seconds north latitude and 163 degrees 23 minutes 29.52 seconds east longitude. She is the coordinate of Tiananmen Square in Beijing, the capital of our great motherland. Click "search", and I won't describe what you see below, so enjoy it slowly!

In order to make you more aware of the meanings of various tools and prompt information, we have illustrated them as follows:

We can see that the left part is a display of various information, so you can ignore it. The upper right part is a graphical browsing window, and the lower part is a toolbar. Please carefully observe the meanings and usage of various tools.

(2) Look at the cities on the other side of the ocean

Google provides satellite photos of different regions with different resolutions. In your hometown, you may only see some mountains, but in some big cities you can even see the roofs! Let's enjoy it together.

Google Earth provides different and detailed information in the following cities, where you can get information about travel, catering, tourism and other aspects:

Clear photos of buildings: most cities in the United States, major cities in Western Europe, Canada and the United Kingdom.

Three-dimensional illustration of cities: 38 major American cities.

detailed road map: USA, Canada, UK and Western Europe.

Google local search: USA, Canada, UK.

Let's go to new york and have a look. If you know its general orientation, you can look for it manually. Or you can directly enter the latitude and longitude: 4 degrees and 42 minutes north latitude and 74 degrees and minutes west longitude. When the height drops to about 6 feet, the building can be seen clearly. For such a height, you can observe the three-dimensional distribution of buildings. Select "Building" on the left side of the tool panel, and a white icon will appear on the top view. At this time, you can change the angle of view by using the "Looking Down" and "Head Up" adjustment levers, and you can feel the shuttle between cities by sitting in a helicopter. Wonderful!

adjust the height to about 4 feet (ft) so that we can see most cities. At this time, everything on the left side of the tool panel can be displayed as needed, and at the most detailed time, every bar and restaurant can be seen at a glance.

(3) Distance display and traffic guide

For cities in the United States, Google Earth provides traffic guides. For two specific locations, you can list the main streets and highways that you need to pass. You can right-click the highlighted city, select "From Here", and then select "To Here" at the destination. At this time, the location of the two places will appear on the left panel, and click "Search" to see the road traffic at a glance.

In fact, the most wonderful thing is that after the search comes to a conclusion, there is a "play" button at the bottom of the list. If you miss him, you can observe the three-dimensional journey from the starting point to the destination, just like sitting in a car and experiencing the whole journey. It is really amazing!

(4) Distance calculation

Google Earth can directly know the linear distance between any two places. I live in Shanghai, and my hometown is Linfen, Shanxi Province. I can do it by using "Measure" in "Tools" in the menu bar. After specifying the distance between two points on the map, I can know the result immediately. The result is "Mile" by default, and we can convert it into "Kilometers" through the drop-down menu. The above picture shows that the linear distance between the two places is 164.43 kilometers.

the above is the main information that this software can provide us. Unfortunately, its focus is still in the United States, and high-definition pictures and some detailed services are concentrated in some big cities, but I hope you can fully tap its powerful three-dimensional display function and clarify the meaning of various specific data, which is also very beneficial to increase your geographical knowledge. Finally, a few tips are provided for you to try:

Double-click a place casually, and the software will descend to the area gently, which is extremely enjoyable visually.

you can add a tag at the place of interest you find. The specific method is: select "Add Tag" in the lower right corner of the tool panel, then just move the mouse to the destination in the map, and the added tag will be required to be saved, which will be more convenient for future access.

the mouse wheel is equivalent to the up-and-down key, with a relatively large range, which is used to quickly change the height.

You can mark several places continuously, so that you can browse continuously. Just click "Play" to achieve the goal of traveling around the world in a few minutes.

Because the resolution of pictures in each location is different, when the data download is marked as 1%, the clearest picture can be obtained.
