The Copernicus Sentinel-1 mission takes us over a part of the Mekong Delta – a serious rice-producing area in southwest Vietnam.
In Vietnam, rice has been a strategic crop for nationwide meals safety. Vietnam is the fifth largest producer of rice on this planet, the vast majority of which is grown within the Mekong Delta – an unlimited flood plain and one among Asia’s most fertile agricultural zones.
Such an unlimited quantity of rice is produced within the Mekong Delta that it’s also known as Vietnam’s ‘rice bowl’. The rice grown right here produces sufficient to make Vietnam the world’s third greatest rice exporter – after India and Thailand.
This multi-temporal picture combines three radar acquisitions from the Copernicus Sentinel-1 mission taken round one month aside to point out adjustments in crop and land circumstances over time. The intense colors within the picture come from adjustments on the bottom which have occurred between acquisitions.
Right here, the primary picture, from 28 October 2019, picks out adjustments in pink and pink, the second from 21 November exhibits adjustments in inexperienced, and the third picture, from 27 December, exhibits adjustments in blue. As seen within the picture, the vast majority of progress within the rice fields is seen in December. The gray areas characterize both built-up areas or patches of land that noticed no adjustments throughout this time.
Our bodies of water replicate the radar sign away from the satellite tv for pc, making water seem darkish. This may be seen within the Bassac River, also referred to as the Hau river, in the fitting of the picture. Ships within the river could be seen as shiny, multi-coloured dots.
The mixture of radar pictures from the Copernicus Sentinel-1 mission may also help monitor and map the evolution of rice cultivation. Radar sensors are significantly helpful owing to their capability to detect waterlogged floor and penetrate the humid cloud protection typical of Asian rice-cultivating areas.
