Gis commanding city emergency

1. Background and significance of the topic.

The city is a complex spatial system consisting of people, the society, the economy, the resources, the environment, and the disasters through interaction, interdependence, and mutual restraint. With the acceleration of urban construction and the rapid expansion of the urbanized structure population, the frequency and degree of disaster accidents caused by the factors, natural factors and the superposition of the two have increased rapidly, making the city's sustainable development function seriously threatened. Security faces unprecedented challenges, and the September 11th incident and the popular SARS epidemic in the spring of XX sparked global thinking. In addition, "safety accidents that occur in industrial and mining enterprises and construction sites every year have also brought us great losses. Sudden events like this are unpredictable and contingent, making it difficult for people to cope, thus realizing urban public Security has great practical significance for safeguarding the economic development and political stability of the region and the whole country. Whether a city has the ability to prevent disasters has become an important indicator to measure its quality and civilization.

At present, the decision to deal with urban emergencies mainly depends on their independent management departments. The effect depends mainly on the amount of information that the leader has and the level of personal knowledge and experience. However, due to too many human factors, it is inevitable that some wrong decisions will be made. In the event of a disaster, wrong decisions can not only lead to delays in organizing people to evacuate and prevent disasters from expanding, but also cause significant casualties and economic losses. In urban public safety research, whether it is a variety of major natural disasters or man-made industrial disasters, each process and link of its monitoring, forecasting, evaluation, and disaster prevention, disaster relief, recovery, education, insurance and integrated management Geographical factors are closely related, such as the spatial and temporal distribution, intensity and frequency of disasters, socio-economic vulnerability and disaster resilience in disaster areas, personnel distribution, emergency response measures for disasters, and emergency plans. Therefore, the comprehensive use of disaster science and information technology to establish an emergency decision-making system integrating basic information management, disaster information management, major hazard source management, various disaster analysis and simulation, public safety planning, and emergency decision-making mode will be played in urban public safety. Fast and accurate auxiliary decision-making role to ensure the safety of people's lives and property to the greatest extent. Therefore, it is extremely urgent to establish a city emergency command system.

The responsibility of the urban emergency command system is to command and dispatch the social and social forces to rescue or help the emergency time in an accurate, timely and efficient manner. Effective command and dispatch must be based on correct decision-making, while scientific and thorough decision-making needs to be based on a large amount of real-time information. Therefore, how to effectively use the government, social information to fully share, comprehensive processing and visually and intuitively give auxiliary decision-making, it becomes an emergency command and traditional regional, closed, departmental unity, and artificial experience to improve modernization and intelligence. The difference between sexual emergency command. The geographic information system gis has become a technical means to achieve the above objectives, and it has been developed in recent years. 2. Method and main content of topic selection research

research method:

1. By reading a large number of materials related to the topic selection, combined with the level of learning, using the evaluation method to comprehensively evaluate the past research, and learn from its experience to implement its own innovative research.

2. Collect relevant data information for testing. In the course of the research, survey methods and interviews were used to further confirm the authenticity of the data.

research content:

With the geographic information system as the platform, the advantages of rs, gps and the three are integrated, and the unique functions of gis visualization and spatial analysis are established. The emergency system model framework with gis as the core and related subsystems are established. Real-time dynamic monitoring of accident scenes and rescue agencies. Real-time scheduling and configuration of people, equipment and vehicles. Provide assistance in the rescue of sudden disasters in cities.

3. Research conditions and possible problems

Research conditions:

In this study, information is collected mainly through online inquiry, field investigation, library inspection, and visits. Based on the shortcomings of past research, I put forward my own views. And verify the expected results through experiments.

potential problem:

1. At present, the research on foreign countries in this area is not comprehensive enough.

2. Due to the huge size of the system, the data may not be easily collected in a limited time due to certain confidentiality of the city. For some emergency configurations you can understand. Lack of authenticity and existence of data.

3. In the secondary development process, due to its limited level, there may be many problems.

4. Major issues and expected results to be resolved

a) Proper data construction planning

b) Platform selection must weigh multiple needs

c) gis should have enough interfaces

d) Support information for multiple services

Conduct active and in-depth discussions on the above issues, analyze the status quo at home and abroad, find out the specific methods that gis applies in urban emergency, and use it to ensure the safety of the city.
