Abstract

The invention discloses a forest fire point monitoring method comprising the following steps: using MODIS data to obtain parameter factors closely related to forest fire hazards like combustible moisture saturation capacity, temperature, humidity, and vegetation coverage rate; fully considering forest real conditions, organically combining all parameter factors, and building a fire monitoring model as fire point primary determining basis; eliminating water body and cloud interferences on said basis, thus obtaining real fire points. The forest fire point monitoring method can fast, automatically and accurately identify fire points, thus greatly reducing the error rate of abnormal interference points, and improving forest fire pint identification accuracy.

Description

technical field [0001] The invention relates to the technical fields of fire monitoring and remote sensing, in particular to a fire point monitoring method applied in forest areas. Background technique [0002] The occurrence of forest fires is generally accidental, and the places of occurrence are generally inaccessible and remote primitive and semi-primitive forest regions, and there are many influencing factors and it is difficult to prevent them. In recent years, with global warming, extreme weather has occurred frequently, and the central and southern regions of my country are more and more prone to continuous high temperature and sunny weather during spring plowing and Qingming period. At the same time, due to economic development, traditional hay and trees have been replaced by gas in rural areas, and with the implementation of the policy of returning farmland to forests, the vegetation in forest areas has become more and more intact. Therefore, wildfires occur freque...
