Embodiment Construction

[0028] An integrated display method of a leakage diffusion model of hazardous chemicals and GIS, comprising the following steps:

[0029] 1. According to the relevant data of the meteorological department or the data obtained by other means, set the meteorological parameters when the leakage occurs, including wind direction, cloud amount, wind speed, etc.;

[0030] 2. According to information sources such as relevant incidents received in emergency reports, set parameters such as the category of hazardous chemicals, leakage amount, and leakage method;

[0031] 3. Set the time parameter when the leakage occurs;

[0032] 4. Click the map with the mouse to locate the leak source and obtain the spatial coordinates of the leak source;

[0033] 5. Set the color of the model output, that is, the color marking of different concentration levels;

[0034] 6. Through the spatial query of ArcGIS, obtain the relevant target information of the leakage source attachment, and this informati...

Description

technical field [0001] The invention relates to an integrated display method of a leakage diffusion model of hazardous chemicals and GIS. Background technique [0002] The development of emergency technology has put forward higher and higher requirements for prediction and early warning model technology in terms of model algorithms and result display effects. The problems of professional models mainly focus on complex computing conditions, strict requirements on parameter constraints, long calculation time, lack of real spatial visual experience in model performance, and so on. It is becoming more and more important to propose a simplified engineering emergency model integrated with GIS, which can quickly provide valuable model analysis results in the daily use of emergency systems and provide effective reference for emergency decision-making. Contents of the invention [0003] The purpose of the present invention is to provide an integrated display method of the leakage ...
