Space Satellite Captures Incredible Views of Rice Fields in Vietnam’s Mekong Delta [Video]

This multi-temporal picture combines three radar acquisitions from the Copernicus Sentinel-1 mission taken round one month aside to point out modifications in crop and land situations over time. The brilliant colours in the picture come from modifications on the bottom which have occurred between acquisitions.

The Copernicus Sentinel-1 mission takes us over half of the Mekong Delta – a significant 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 in the world, the bulk of which is grown in the Mekong Delta – an enormous flood plain and one of Asia’s most fertile agricultural zones.

Such an unlimited quantity of rice is produced in the Mekong Delta that it’s sometimes called 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 modifications in crop and land situations over time. The brilliant colours in the picture come from modifications on the bottom which have occurred between acquisitions.

Right here, the primary picture, from October 28, 2019, picks out modifications in pink and purple, the second from November 21 exhibits modifications in inexperienced, and the third picture, from December 27, exhibits modifications in blue. As seen in the picture, the bulk of development in the rice fields is seen in December. The gray areas characterize both built-up areas or patches of land that noticed no modifications 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 in the Bassac River, often known as the Hau river, in the best of the picture. Ships in the river may be seen as shiny, multi-colored dots.

The mixture of radar photographs from the Copernicus Sentinel-1 mission might help monitor and map the evolution of rice cultivation. Radar sensors are significantly helpful owing to their means to detect waterlogged floor and penetrate the humid cloud protection typical of Asian rice-cultivating areas.
