Construction method and application method of offline earthquake disaster loss evaluation system

Abstract

The invention relates to a construction method and an application method of an offline earthquake disaster loss evaluation system. The construction method comprises the steps of obtaining basic data;wherein the basic data comprises basic geographic data and earthquake professional element data; processing and sorting the basic data to generate offline map data; generating earthquake loss pre-evaluation result data of each kilometer grid under different intensities by utilizing the earthquake loss evaluation model; performing block storage on the earthquake loss pre-evaluation result data of each kilometer grid under different intensities; superposing the stored earthquake loss pre-evaluation result data of each kilometer grid under different intensities with the offline map data to obtaina drawing expression of a loss result; based on object-oriented programming and a graphic image processing technology, constructing and developing an interactive interface and an interactive operation function, and obtaining the offline earthquake disaster loss evaluation system. According to the invention, the efficiency and stability of earthquake disaster loss assessment can be improved.

Description

technical field [0001] The invention relates to the field of earthquake disaster assessment, in particular to a construction method and an application method of an off-line earthquake disaster loss assessment system. Background technique [0002] As we all know, earthquake disaster is a kind of extremely destructive natural disaster, often causing a lot of property loss and casualties. After the earthquake, quickly assessing the disaster situation in the shortest time and obtaining the disaster assessment results are an important basis for the government's decision-making and deployment of earthquake relief, and it is the primary task of earthquake emergency work. With the development of society, higher requirements are put forward for earthquake emergency work both in terms of "time" and "space". In terms of "time", the faster the better; in terms of "space", it is required to move the center of gravity of the position forward, so as to realize efficient and orderly emerge...

AI Technical Summary

Problems solved by technology

[0004] (1) It cannot meet the needs of earthquake emergency work in any scenario: the operation of the system depends on the pre-deployed back-end database and commercial GIS software platform, which are generally fixedly deployed in the earthquake emergency command center or laboratory. Work teams and earthquake site emergency headquarters cannot be applied

[0005] (2) Development and deployment are relatively complex and costly: system operation requires the deployment of special databases and GIS software in advance, the system development and deployment cycle is long, and the professional requirements for system maintenance and users are high; at the same time, a large amount of third-party business will be generated Software purchase fee or entrustment fee for system development and deployment

Therefore, the system development and deployment cycle is long, the cost is high, and the system upgrade, expansion and promotion are also relatively difficult.

[0006] (3) Operational stability and computing efficiency need to be improved: due to the deployment of third-party commercial software platforms or network environments, the system has relatively strict requirements on the software and hardware environment, and the system’s operational stability is challenged to a certain extent

In addition, the system is mainly based on the secondary development and deployment of the third-party software platform, and the improvement of computing efficiency and performance optimization are limited.
