Question 1: What is the difference between Google Maps and Google Earth? Google Maps is a software similar to Baidu Maps, which can provide maps and navigation functions in different cities;

Google Earth ( Google Earth) is a mosaic of satellite photos, which can show the situation when the photo was taken (buildings, streets, vehicles on the street, etc.), but there is generally no information such as vehicles on the map, and the resolution is completely different. .

Question 2: What satellite does Google Earth use? Google EARTH's satellite images are not a single data source, but a data integration of satellite images and aerial photography. Some of its satellite images come from the QuickBird commercial satellite of DigitalGlobe of the United States and EarthSat (an American company, most of the images come from the Land Satellite LANDSAT-7 satellite). The aerial photography part comes from BlueSky (a British company, and Mainly aerial photography, GIS/GPS related businesses), Sanborn Company (an American company, mainly engaged in GIS, geographical data, aerial survey and other businesses), etc. Having said that, let’s briefly introduce the commercial imaging satellites in our world: The top three satellite image resolutions in the world are currently: QuickBird of the American DigitalGlobe company, IKONOS of the United States, and SPOT5 of France. Among them, SPOT5 can provide images with a resolution of 2.5 meters, IKONOS can provide images with a resolution of about 1 meter, and Jetbird can provide high-precision images with a maximum resolution of 0.61 meters, which is the highest level of commercial use in the world. In terms of satellite imagery, the U.S. Pentagon gives its three major partners DigitalGlobe, IKONOS and ORBIMA Google Earth billions of dollars in funding every year. In return, of course, the satellite data of these companies will be handed over to the Pentagon for military applications as soon as possible. Moreover, commercialization is not allowed within specified time limits for certain sensitive areas. Of course, these companies will still sell images outside the restrictions. For example, Keyhole (later Google EARTH) is a buyer of DigitalGlobe, and many in my country also have business cooperation with DG companies. For example, the local *** where the author works is with this company. I purchased a satellite image of a certain band of this city (a provincial capital city). The size of the entire image was more than 6GB and cost hundreds of thousands of yuan. In addition, Guangdong purchased more than 2,500 square kilometers of satellite images of a certain area in 2004 at a cost of 1.46 million yuan. The same is true for regional prices. If you order it, of course it will be more expensive). Of course, if any students are interested, they can purchase it. These companies all have agents in mainland China, and Google Earth has also laid a small foreshadowing for DG’s satellite image sales

Question 3: What is the geographical coordinate system of Google Earth? 5 points

Question 4: What does Google Earth do? Google Earth is a virtual globe software that allows you to have a bird's eye view of the world. Users can search for a specific area on the 3D map, zoom in and out of the virtual image, and then form a travel guide. In addition, Google Earth has also carefully crafted a special option - a bird's-eye view of the journey, which makes motorists more energetic. In the future, more terrains will be covered, including pastoral areas, wastelands, etc.

Question 5: What is Google Earth? What is its use? How to use a software developed by Google to record satellite maps of the world. It was only a long time ago. In countries such as Europe or the United States, Google uses Street View. The collection vehicle collects street conditions and you can view 3D images in 360 degrees. There is also a simulated airplane that you can operate, allowing you to experience the effect of viewing city attractions on an airplane. However, this requires high graphics cards. Generally speaking, it is just a world map

Question 6: What is Google Earth? What is it used for? How to use the virtual globe software developed by Google. It arranges satellite photos, aerial photography and GIS on a three-dimensional model of the earth. However, it is not currently available in China. You need to use special tools

Question 7: What is Google Earth used for? Google Earth is a virtual globe software developed by Google. It arranges satellite photos, aerial photography and GIS on On a 3D model of the Earth. Google Earth was launched globally in 2005 and was named one of the 100 best new products in the world in 2005 by "PC World Magazine". Users can browse high-definition satellite images from around the world for free through a client software downloaded to their computers. Google Earth uses public domain images, licensed aerial photography, images from the KeyHole spy satellite, and photos of cities and towns from many other satellites. There are even pictures that are not provided by Google Maps. There are two types: free version and professional version.

The download address of Google Earth is: earth.google

Question 8: What is the difference between Google Maps and Google Earth 1. Google Earth is a virtual globe software developed by Google. It combines satellite images, Maps, encyclopedias and flight simulators are integrated and arranged on a three-dimensional model of the Earth. Google Earth has been controversial due to leaks.

2. Google Earth can take you to anywhere on the earth, where you can view satellite images, maps, various terrains and 3D buildings, including the Milky Way in outer space and ocean canyons.

3. Google Maps is an electronic map service provided by Google to the world, including locally detailed satellite photos. It can provide three views: one is a vector map (traditional map), which can provide political areas, transportation and business information; the other is satellite photos of different resolutions (top view or 45° image, basically the same as the satellite photos on Google Earth) ; The third is a topographic map, which can be used to display terrain and contours.

Question 9: What is the difference between Google Earth Professional and regular versions? Simply put, the images are clearer, the information is richer, and the service is better.

Professionally speaking, the added functions of Google Earth Professional Edition compared to the regular version are as follows:

1. GPS data interface import - import route driving content from GPS devices; < /p>

Note 1. Currently only MaGoogle Earthllan and Garmin devices are supported;

Note 2. Exporting route driving content to GPS devices is not supported;

2. Image height Precision printing (higher than the monitor screen resolution);

3. Email customer service (question answering, etc.) support;

4. Comments provide a sketching function, which can define More intuitive bookmarks and annotations, and sharing through KML;

5. Data input through csv files.

Note: Google Earth Pro is a paid upgrade version for commercial use and has stronger functions than Google Earth Plus. This version supports plug-in functionality.

Suitable for professional and commercial use

Google Earth Pro will make regional survey and representation a very simple matter. Enter the destination address, and you can watch Google Earth fly from the departure point to the destination, and display commercial institutions, schools, shopping malls, etc. along the way in 3D mode. You can export the simulated records of a city into video format and display these Records are saved and shared with colleagues or clients. Google offers a seven-day trial of the Google Earth Pro version.

Mature data streaming technology ensures that only the area data you specify is delivered to you;

Provides global landform images and 3D data - a total of more than 1000GB of high-precision urban data Satellite imagery;

Area searches let you search for restaurants, hotels, and driving directions. It can also accurately simulate 3D demonstrations of buildings, and use the multi-layer function to flexibly query and save search results.

The contact layer function of each park, school, hospital, airport, shopping mall, etc. can be displayed separately;

Design sketches by importing road and building location information to draw buildings. Blueprint;

Able to create annotations with lines and polygonal graphics;

Batch upgrade to location information of more than 2,500 areas through spreadsheets;

KML bookmark sharing - - Provides location bookmark recording function, and allows import and export, which makes the use and communication of Google Earth more convenient;

Question 10: What is the production principle of Google Earth? 200 high school students, just improvise.

This thing should be a digital earth, something made with RS, GPS, and GIS. Geographic information of different precisions is displayed through the overlay of many information layers. The source of the information layer is the satellite. Although the earth is nearly round, no matter what your scale is, the satellite can find the corresponding plane map to cover your screen.

The amount of data transferred when Google is running is very large. It is difficult for ordinary computers to accommodate such large amounts of data, so there is no stand-alone version of this thing (no one can afford it). Brother, if you want to make a large-scale thing based on Google's standards, it will be a little difficult.

Regarding the issue of image loading speed, I remember that I seemed to have seen it (but forgot...). It can be obtained from Baidu, so go and see for yourself. The keywords I searched for at that time were also related to Google.

Other questions,,, I don’t understand.

The expression may not be clear and the content may be verbose, so please forgive me.

Finally, I wish you success in making what you want to do.

Good luck!
