China uses satellite imagery to fight COVID-19

Coronavirus outbreak has severely impacted the entire world. The same as all the other countries, China are engaged in hard combat with the virus. SpaceWill documented the milestones with satellite imagery.

Hospital built in 10 days

Two makeshift hospitals named Huoshenshan and Leishenshan were built in few days to treat confirmed infected patients intensively in Wuhan, the hardest-hit city by the coronavirus outbreak in China. Huoshenshan hospital started to build on January 23, 2020 and was officially delivered on the night of February 2. The whole project was completed in 10 days, with an area of 34,000 square meters and 1,000 beds. Another emergency hospital named Leishenshan started to construct on January 25, 2020 and was put into use on February 8. It took 14 days to build, covered nearly 80,000 square meters with a total of 1,600 beds. The whole nation and SpaceWill were keeping a close eye on the constructions of the two hospitals. GF-2 shoot the building on January 30 and February 9, clearly recorded the quick progress during the days.

Resumption of work and production

 

Orderly resumption of work and production has begun in different regions and industries in China since mid-February, 2020. The resumption rate of 41 cities in China has surpassed 90% and industries like petroleum, telecommunication, power and transportation have reached 95% by March 2. LST (Land Surface Temperature) can be retrieved from Thermal Infrared Image which reflects the terrestrial thermal behavior. By comparing LST from different periods, we can see a clear trend of resumption in China. Moreover, PRD (Pearl River Delta) is one of the major economic regions in China, centered with high-tech industrial parks and large manufacturers. LST of this region was used by CCTV (China Central Television) to reflect the local resumption of production. The visualization of location-based data demonstrates a direct observation of regional economic recovery.

SpaceWill will continuously explore the potential use of geospatial data to its extent and do our best to disseminate useful information for disease surveillance and control. Furthermore, SpaceWill is delicated to develop partnerships within and outside the industry, opening the door for wider application of geospatial in global public healthcare.
