NASA satellite captures a picture of India’s largest salt producer from space
NASA Earth Observatory
- The National Aeronautics and Space Administration’s (NASA) Earth Observatory shared an image of
salt ponds in Gujarat— India’s largest salt producer.
- Gujarat’s Bhavnagar and the Gulf of Khambhat are highlighted in the image.
- Similar salt deposits have been captured by NASA of other major salt producing regions around the world.
Gujarat accounts for three quarters of India’s annual salt production and is home to half of the country’s salt workers.
The image captured by the Operational Land Imager ( OLI) aboard the Landsat 8 Satellite shows the city of Bhavnagar — one of the leading salt-producing districts in Gujarat — on February 28, 2019.
The colourful rectangles in the image are salt evaporation ponds, according to the National Aeronautics and Space Administration’s (NASA) Earth Observatory. It’s a feature often found in major salt-producing areas.
The Gulf of Khambhat is also seen in the image. In the past, it was responsible for 24% of the salt production in the state. Because of the abundance of salt in the area, it is also home to the Central Salt and Marine Chemicals Research Institute.
Here are some other salt producing regions captured by NASA:
