In dealing with emergencies, most of the emergency work needs to be based on spatial data as well as spatial data and specific attributes of the object data. It is possible to realize rapid and accurate positioning of emergency and resources, the real scene reappearance of on site and surroundings and the simulation of the real scene by using GIS, 3D real scene and 3D simulation. The system provides the basic information support for management personnel to quickly gain emergency situation, know about surroundings, predict incident development trend, deploy emergency resources and take measures. Emergency response training can improve reality and increase efficiency and effectiveness based on 2D and 3D GIS, 3D real scene and 3D simulation.
3D GIS shows diverse information of dangerous chemical enterprises, surrounding roads, rescue resources and rescue force, and is a unified input and output channel for integrated operation management, emergency rescue and command system, 3D training and simulation system, 2D and 3D GIS, 3D real scene and 3D simulation. The system provides simulation display, 2D/3D display and spatial visualization of the various systems and realizes the spatial data service, query and analysis service, as well as assistant decision-making support
Support platform achieve assistant decision-making based on a combination of multivariate data, including spatial data, imaging data and 3D simulation data. It can also provide support for integrated management system, emergency rescue and command system and 3D training and simulation drill.
Geographic information of monitoring and emergency command platform mainly refers to basic geographic information for emergency resources, including digital line graphic, image map, digital elevation model and navigation data. Production safety geographic information mainly include such information as supervised enterprise, major hazards, surveillance cameras, railway crossing, work location in railway crossing, rescue units, dangerous explosive enterprises, non-mining enterprise, fireworks enterprise, relief supplies distribution, medical aid agency, rescue and shelters, dangerous chemicals distribution, accidents distribution and associated units, etc.
Vector images and aerial image uses the global positioning satellite coordinates WGS84 (geocentric coordinate), demonstrated by latitude and longitude.
Vector electronic map data is divided into basic geographic information, public geographic information and business special geographic information. Basic hierarchical requirement is as follows:
1, the foundation geography class layer requirements
hierarchically display such information as administrative divisions, roads, centerline, buildings, green land, river system, etc.
