China will build a Chinese-made Google Earth

On the eve of the Spring Festival, the State Bureau of Surveying and painting made a strategic decision: to start the "National Geographic information public service platform" construction project and build China's "Google Earth ). Academician Li Deren told reporters that at the end of last November, the state ing Technology Commission held a meeting in Shanghai and put forward suggestions for starting the project.

If you are a "Google Earth fan", you will surely find that when you have a bird's eye view of Washington, New York and other North America, your "float" eyes can jump down to the street car. However, if you see "float" over a big city in China, the Street buses are blurred. "Why? Chen Jing, associate professor of the State Key Laboratory of surveying and mapping remote sensing information engineering, said that Google may be responsible for positioning the business market. He said that image images on Google Earth are obtained from companies such as jetbird, with limited data and cost problems.

"For domestic geographic information data, we have great advantages. The national surveying and ing system obtains geographic information through various surveying and ING means, some are ground GPS manual plotting, some are aerial shooting surveying and ING. In addition, other departments have their own channels to obtain data, which is more clear and comprehensive. In the future, we will want to check which village and village can be implemented as long as they are not kept confidential ." Chen Jing said that this is the biggest advantage of building "Google Earth" in China. According to the Yangtze River Daily
