A remote sensing rapid monitoring and publishing method for global thermal anomaly information based on multi-source remote sensing data

Abstract

The invention relates to a global heat abnormal point information remote sensing rapid monitoring and issuing method based on multi-source remote sensing data. The global heat abnormal point information remote sensing rapid monitoring and issuing method includes the steps of obtaining MTSAT satellite data in real time, carrying out radiation processing and geometric processing on each MTSAT satellite datum, preliminarily determining an area where a suspected heat abnormal point is based on the MTSAT satellite data, using MODIS data to carry out radiation processing and geometric processing, using the wave band operation to obtain the suspected heat abnormal point, using HJ-1 data to carry out radiation processing and geometric processing, using the HJ-1 data to determine the information of the heat abnormal point, making a heat abnormal point remote sensing monitoring report, and issuing the heat abnormal point remote sensing monitoring report to related organizations. According to the global heat abnormal point information remote sensing rapid monitoring and issuing method, forest fire disasters and grassland fire disasters which are strong in abruptness and big in destructive effect can be effectively found in time, key supporting roles can be played on emergency responses to the forest fire disasters and the grassland fire disasters, and the global heat abnormal point information remote sensing rapid monitoring and issuing method is of great significances on guaranteeing the life and property safety of people, maintaining the forest and grassland ecological environments and the like.

Description

technical field [0001] The invention relates to the field of surveying and mapping remote sensing, in particular to a remote sensing rapid monitoring and publishing method for global thermal anomaly point information based on multi-source remote sensing data. Background technique [0002] Forests and grasslands are the main regulators of the global climate and important resources necessary for human life and production. Forest fire refers to the behavior of forest fire that loses human control, spreads and expands freely in the forest land, and brings certain harm and loss to the forest ecosystem and human beings. Grassland fire is a disaster caused by natural or man-made fires in grasslands, grasslands, and grasslands. Forest and grassland fires are characterized by strong suddenness and great destructiveness, causing harm to the safety of people's lives and property, highly destructive to the ecological environment of forests and grasslands, and will promote the degradati...

Problems solved by technology

Matson and Dozier proposed an automatic detection algorithm for biocombustion using GOES / VAS data, and monitored fires by combining the mid-infrared and visible light bands of GOES satellites. However, GOES / VAS satellite data are limited by spatial resolution, and it is difficult to accurately monitor GOES satellites alone. Forest and Prairie Fire Information

[0008] At present, the difficulty of forest fire monitoring is that the monitoring range is large, the timeliness is high, the remote sensing data involved is large, and the processing efficiency is not high; It is difficult to extract fire-related parameters such as smoke optical thickness and burn area by using only one type of satellite data
