Atlas of Human Settlements @ Turkey & Syria
In response to the recent #turkeyearthquake & #syriaearthquake, we are proud to announce that our Atlas of Human Settlements (AHS) 2021 #datalayers for #Turkey and #Syria are now publicly available. The AHS data offers crucial intelligence for #crisismanagement bodies in their immediate efforts to respond to the #disaster, as well as to help inform the most #sustainableapproach to long-term rebuilding efforts.
Our AHS product is designed to help #response agencies answer questions such as: 1. Where were buildings clustered in the highest density before the incident? 2. Which clusters coincide with the highest population density? 3. How best to approach / access the densest built-up parts within settlements?
More information and free access to the AHS for #Turkey and #Syria can be found on #GoogleCloud’s Analytics Hub listing page at https://t.ly/MRWZ
You can read our full statement here: https://lnkd.in/dPUVxwFZ

Guangzhou is one of China’s fastest growing cities, its population more than tripling from 5 million in 1980 to 18.6 million in 2020. The city has seen a huge influx of migrants in recent years, spurred by its fast-growing economy and high labor demands. Guangzhou is at the heart of the Guangdong–Hong Kong–Macau Greater Bay Area, the most-populous built-up metropolitan area in the world with approximately 65.5 million residents.

Eratosthenes of Cyrene
He is best known for being the first person known to calculate the circumference of the Earth, which he did by using the extensive survey results he could access in his role at the Library; his calculation was remarkably accurate. He was also the first to calculate Earth’s axial tilt, which has also proved to have remarkable accuracy. He created the first global projection of the world, incorporating parallels and meridians based on the available geographic knowledge of his era..
