Research background and significanceThe importance of the ocean in the global system: The ocean covers about 71% of the earth's surface and is an important part of the global climate system. It plays a key role in regulating global climate, material circulation and energy exchange. Although traditional ocean monitoring methods such as shipborne measurements and buoy monitoring can obtain certain ocean information, they have problems such as limited spatial coverage, poor temporal continuity, and high manpower and material costs. Although satellite remote sensing can be used for large-scale observations, it has shortcomings in obtaining some details and specific parameters, such as the difficulty in accurately obtaining some optical characteristic parameters of water bodies. With the co...

Research background and significanceUsing drones equipped with hyperspectral imagers to collect cotton data, and using ground spectrometers to collect ground data simultaneously. After data preprocessing, airborne cotton orthophotos were obtained, and the accuracy and reliability of the data were verified by typical spectral characteristic values and first-order differentials, which provided a reference for cotton growth status monitoring. It not only improved the efficiency of cotton planting management, but also provided a scientific basis for cotton pest control, yield and quality evaluation, and promoted the modernization and intelligent development of cotton production.Equipment application introduction1. Cotton growth status monitoring: Remote sensing monitoring of cotton by drones e...
