Using Remote Sensing to Map Rice Paddy Drop in the Mekong Delta
Satellites including Europe’s Sentinel-1A can now track the rise and fall of different agricultural products around the world. The satellite’s imagery showed that rice production in the Mekong Delta has decreased in the past year.
Using Landsat Imagery to Find Shipwrecks
Satellite imagery from Landsat 8 has been used by a Belgian marine research institute to detect shallow water shipwrecks. Satellite imagery from Landsat 8 can detect the concentration of sand and silt particles in the ocean, which can then be used to pinpoint a potential shipwreck location.
Developing Earthquake Damage Maps from Satellite Imagery
Researchers are working on developing remotely sensed maps that may assist locals in assessing damage and managing the aftermath with future earthquakes.
