Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.
This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.
According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.
At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.

Economy rebounding after drop
China's economy experienced a deep reduction in the first quarter due to the novel coronavirus outbreak. 1.. This indicates that the country's recovery has gained a firmer footing, officials and economists said on Friday.
2.. However, it remains unclear whether the government will still set a GDP growth target for the year. Economists said China's policy for the next step needs to focus on stimulating(刺激) demand and stabilizing(稳定)employment to promote economic recovery.
Mao Shengyong, NBS spokesman, said the outbreak created a serious blow to the country's economy in the first quarter, but major economic indicators(指标) rebounded in March.3..
Lian Ping, chief economist at Zhixin Investment, said the government needs to strengthen policy support to prevent the economy from suffering a second wave of blows from the global economic downturn. 4.. While most large companies have resumed production, according to NBS calculations, many smaller companies are still struggling to resume work under rising financial difficulties and labor shortages.
Retail sales dropped by 19 percent year-on-year in the first quarter, which indicated that domestic demand remains relatively weak and there is still room for policies to effectively boost households' consumption(消费), economists said. 5.. The urban unemployment rate was 5.9 percent in March, down by 0.3 percentage point from February, according to the NBS.
A.Urban household income declined by 3.9 percent year-on-year in the first quarter.
B.But major economic indicators improved mostly in March.
C.China's GDP in the first quarter contracted by 6.8 percent from a year earlier according to the National Bureau of Statistics.
D.Chinese economy is recovering as more companies are borrowing to promote their production recovery.
E.And the country's economic performance will improve further in the second quarter.
F.Chinese companies, including exporters, have seen an increase in cancellations(取消) of orders.
G."More support needs to be given to households as the decline(下降) of residents' income
