Introduction
Satellite remote sensing fire monitoring is an important technical tool for forest and grassland fire prevention, straw burning control, and biomass burning carbon emission calculation.
Duan, at present, many industries such as emergency management, forestry and grassland, agriculture, ecological environment, meteorology and electric power have carried out satellite remote sensing fire monitoring. In reality
In practical applications, different units may adopt different processing methods and processes in satellite remote sensing fire monitoring, including different fire point judgments.
There may be large discrepancies in the results of satellite remote sensing fire monitoring due to different recognition methods, fire point intensity calculation methods, and fire area area calculation methods.
This has brought difficulties to fire fighting and disaster relief, loss assessment and other work. Therefore, it is necessary to standardize the satellite remote sensing fire monitoring technology.
