Problems solved by technology

Optical remote sensing images are rich in spectral information. When the weather conditions permit, the acquisition and interpretation of optical images are relatively simple. However, optical remote sensing is easily affected by the atmosphere, cannot penetrate clouds, and cannot perform all-weather operations. ) can work all day and all day, and has a certain penetrating power to clouds and atmosphere

Embodiment

[0033] Application of inundation assessment to the 2013 summer flood in Heilongjiang

[0034] 1. Research area

[0035] Taking the 2013 summer flood in Heilongjiang Province as an example, using 5 scenes of 30m resolution Landsat8 images 1-2 months before the flood, and 4 scenes of 15m resolution SAR images acquired from COSMO-SkyMed satellite after the flood, as shown in figure 2 shown. The experimental area is located near the Sino-Russian border - the Heilongjiang River Basin, which is one of the areas where floods are more serious. The area includes part of the Heilongjiang River Basin, part of the Songhua River Basin, part of the Wusuri River Basin, and also includes Fuyuan County, Heilongjiang Province, Tongjiang City, Suibin County and other counties and cities.

[0036] 2. Extraction of water body information before the flood

[0037] Using the support vector machine method, for Landsat8, the extraction results are as follows image 3 shown.

[0038] 3. Extractio...

Abstract

The invention relates to a method for processing flood disaster inundation assessment information based on band calculation, which comprises the steps of 1) firstly, extracting water information before a flood disaster; 2) then extracting water information after the flood disaster; and 3) finally, carrying out assessment on flood disaster inundation according to the water information before and after the flood disaster. Compared with the prior art, the method provided by the invention makes full use of water partition conditions before and after the flood disaster and carries out flood disaster inundation assessment quickly.

Description

technical field [0001] The invention relates to a method for processing flood disaster submersion assessment information, in particular to a flood disaster submersion assessment information processing method based on band calculation. Background technique [0002] Remote sensing is divided into optical remote sensing and microwave remote sensing. As an effective means of obtaining ground information, it can quickly obtain information on submerged areas. Optical remote sensing images are rich in spectral information. When the weather conditions permit, the acquisition and interpretation of optical images are relatively simple. However, optical remote sensing is easily affected by the atmosphere, cannot penetrate clouds, and cannot perform all-weather operations. ) can work around the clock and around the clock, and has certain penetrating power to clouds and the atmosphere. Usually floods are accompanied by heavy rain and dark clouds, so SAR images are more suitable for post...
