Embodiment Construction

[0016] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0017] The invention provides a method for analyzing earthquake precursors based on satellite thermal infrared data and GIS, such as figure 1 As shown, including the following steps S1-S5:

[0018] S1. The base station receives the surface data transmitted from the satellite, and the third-party software converts the surface data into LD2 files.

[0019] S2. Extract the channel data of the surface thermal infrared part from the LD2 file according to the latitude and longitude range of the research area.

[0020] In the embodiment of the present invention, the channel data extraction method is specifically:

[0021] St...

Abstract

The invention discloses an earthquake precursor analysis method based on satellite thermal infrared data and a GIS. An earthquake prediction analysis is carried out by means of thermal infrared data +GIS, so that the accuracy is improved; the data for the analysis has the large source, so that the research effect is good. Besides, the research direction of the earthquake precursor is extended; and with the GIS way, all quantitative factor that may cause any influence on the earthquake occurrence are accommodated into spatial operation, so that the restriction of analysis of the geological factors and geological formation is eliminated.

Description

technical field [0001] The invention belongs to the technical field of earthquake prediction, and in particular relates to the design of an earthquake precursor analysis method based on satellite thermal infrared data and GIS. Background technique [0002] Southwest China is an area with a high frequency of earthquakes, which generally have the characteristics of high magnitude and strong hazards. Each major earthquake causes huge loss of life and property, and destroys social harmony and stability. So there is an urgent need for new breakthroughs in earthquake disaster prevention. However, earthquake prediction is a difficult problem in the world, mainly because the time, magnitude and location of the forecast are difficult to approach the real earthquake situation. At present, domestic earthquake precursor data analysis methods are various, and the technology is also complicated. Various earthquake precursor analysis methods emerge in endlessly, but there are problems of ...
