How to use satellite land

Google Maps can be said to be the most interesting and practical application since the Internet age. Using Google Maps is as simple as looking at photos. You can zoom in at will to see the close-up of the earth's surface, or you can observe the landform of the whole area from a distance. To adjust the distance you look at the map, use the control key (1).

In addition to the famous satellite map, Google Maps also provides street maps of Taiwan Province Province. The main roads are clearly marked, even in the metropolitan area, there are lane numbers. To switch map types, use the control (2).

It's not enough just to look at the map. Google Maps also provides punctuation marks. Punctuation function is added by the author using API. Usually, as long as you move the mouse to the balloon, a small window will automatically pop up with a brief introduction about this specific point; Sometimes in order to avoid trouble, the author sets the balloon to pop up when you click it twice.

Other functions are as follows:

1. Hold down the left mouse button and drag to move the map up, down, left and right.

Click anywhere on the map twice, and this point will automatically run to the center of the map. The advantage of this function is that you can easily move a place you are interested in to the center, then zoom in, zoom in and zoom in again.

3. At any time, there is a line at the bottom of the map indicating the latitude and longitude coordinates of the center point of the map. This is very useful information, because it is used to communicate with others about a point you have found, or to find the corresponding similarities on other maps.

4. There is a community map at the lower right of the map, which shows the geographical location you see now in a relatively large range. Of course, there is also a drag and drop function. Google Earth (GE) is a virtual earth software developed by Google, which combines satellite photos, aerial photos and GIS cloth.

On the three-dimensional model of the earth. Google Earth was launched to the world in 2005, and in 2005 it was rated as the best in the world 100 by PC World magazine.

One of the new products. Users can browse high-definition satellite images around the world for free through a client software downloaded to the computer. Google Earth can be divided into free version and professional version. Nokia Maps is a leading provider of comprehensive electronic map information, and its products are suitable for car navigation systems, mobile navigation devices and Internet-based map applications. Nokia Maps is based on the advanced "mixed vector diagram" technology, which can support 46 languages in 74 countries around the world.

Audio navigation, communication with more than 26 countries.

180 The general information query, detailed map and place name map of more than 80 countries have covered 38 countries. Users who use other Nokia smartphone terminals. It has no hidden cost, the best global coverage, no network connection, voice indication and traffic information during navigation, 3D

Effects and other effects. Due to a large number of errors in Apple's iOS 6 map application, the introduction of Apple Maps will not be released for the time being. The following is an open letter from Apple CEO Tim Cook.

To our users:

At Apple, we are committed to developing world-class products and providing users with the best experience. However, the map service we launched last week failed to fully realize this promise. We apologize for the disappointment caused by this problem to users. We will take all possible measures to improve the map service. We launched the map service in the first version of the iOS system. With the passage of time, we hope to provide users with better map services, including functions such as turn-by-turn navigation, voice and overpass, and introduce vector map data. In order to do this, we developed a new map service from scratch. More than 65438+ billion iOS devices use the new version of Apple Maps, and more users join every day. In just over a week, iOS users searched for nearly 500 million locations in the new map service. The more users use the map service, the better the map service will become. We are glad to get your feedback. While we improve our map service, you can try other options, such as downloading Bing, MapQuest and Waze map applications from the App Store, or logging in to Google and Nokia websites to use their map services and creating shortcut icons on the home screen. At Apple, everything we do is to make our products the best in the world. We know you have such expectations. We will continue to make unremitting efforts until the map service reaches the same high standard.

Apple CEO referred to as DG. It is a leading enterprise in the global commercial earth imaging and geospatial information market. The company uses Quantum's StorNext data management software to help it bring its products to market faster. Digital earth images are of great significance to various industries, including energy exploration and geographic information.

Zoning, environmental monitoring, emergency response planning, intelligence and 3D simulation. Its customers and partners include Google and many international companies, government agencies and news media. DigitalGlobe operates three imaging satellites: Worldview I, Worldview II and QuickBird. These satellites can collect high-resolution commercial earth images. Compared with any other existing commercial satellite images, they can provide images with the largest size, the largest on-board storage capacity and high resolution.

DigitalGlobe acquires GeoEye.

2065438+In July, 2002, GeoEye Company in Herndon, USA, announced that it was acquired by its competitor DigitalGlobe Company for 900 million US dollars, so as to ensure that it can still get lucrative contracts despite the federal budget cuts. GeoEye had previously tried to acquire DigitalGlobe in Denver maliciously, but it was rejected by the latter. 20 12, 1 1, both parties have completed this merger.

The two companies have been competing in the field of high-resolution commercial satellite images for many years. They sell products to federal agencies, the military and other departments that need images. The acquisition will enable the two companies to save investment in commercial satellites. The merger of the two companies marks a change, which can not only provide one-stop service for users who need American images, but also respond to the federal government's reduction of geospatial budget. Because we don't know how much the federal budget will be cut, we can't judge which areas of the industry will be affected. 2012110 was acquired by DigitalGlobe in October.

Simply put, the high-resolution images collected from orbit and processed by SGI Altix 350 system will be able to identify objects on the ground of 16 inches or more. With this resolution, people will be able to identify the plates on the baseball field or count the number of sewer entrances on the city streets. GeoEye- 1 can not only capture black-and-white (full color) images with a resolution of 0.4 1m and 1.65m color (multi-spectral) images, but also accurately determine the target position with a positioning accuracy of 3m. Therefore, once put into use, GeoEye- 1 will become the most powerful commercial imaging satellite with the highest resolution and accuracy in the world today.
