Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] figure 1 is a block diagram of the flood disaster assessment system provided by the present invention, such as figure 1 As shown, the system includes a data acquisition unit, a vegetation index calculation unit and a disaster assessment unit. Wherein, the data acquisition unit is used to obtain the pre-disaster and post-disaster remote sensing data of the disaster-affected area; the vegetation index calculation unit is used to calculate the pre-disaster and post-disaster vegetation indexes respectively according to the pre-disaster and post-disaster remote sensing data; the disaster assessment unit is used for The degree of disaster damage is determined...

Abstract

The invention relates to the flood disaster assessment technology field and discloses a flood disaster assessment system and method. The flood disaster assessment system comprises a data obtaining unit for obtaining remote sensing data before a disaster and after a disaster in an affected area, a vegetation index calculation unit used for respectively calculating vegetation indexes before the disaster and after the disaster according to the remote sensing data before the disaster and after the disaster, and a disaster evaluation unit used for determining a disaster degree according to the vegetation indexes before the disaster and after the disaster. The flood disaster assessment system and method respectively calculate the vegetation indexes before the disaster and after the disaster according to the remote sensing data in the affected area before the disaster and after the disaster and determines the disaster degree according to the vegetation index. The flood disaster assessment system and method can automatically obtains the disaster degree of crops according to the remote sensing data before the disaster and after the disaster, have advantages of objectivity and high efficiency and provide reliable data support and basis to a disaster prevention and reduction department.

Description

technical field [0001] The invention relates to flood disaster assessment technology, in particular to a flood disaster assessment system and method. Background technique [0002] The commonly used flood disaster monitoring method is to analyze the flood situation of the watershed through the hydrological data obtained from the hydrological actual measurement stations on the ground. These data are point information, not complete information on the watershed surface, and it is difficult to grasp the situation of flood disaster in a timely, accurate and comprehensive manner. condition and extent of loss. [0003] At present, with the development of spatial information technology such as remote sensing and geographic information system, the role of remote sensing technology in flood disaster assessment will be paid more and more attention. For example, according to the irregular distribution of flood submerged range, a grid-based flood loss calculation model can be proposed. I...
