Research on the Standard Methods of Emergency Management Pre-warning Signals Based on GIS

To meet the needs of emergency management for geographical information system, this research analysis of function of GIS which are suitable for pre-warning signals, this research take the comparing manifestation between the function analysis rendering graphics with one mine map, the layer overlaying schematic diagram, and special map classification displaying schematic diagram. Meanwhile, this paper expounds comprehensively the function and principle of GIS which suits to the application in pre-warning signal system. On the ground of the former research, this paper presents standard method of pre-warning based on GIS, carries on the empirical research which with coal and gas outburst pre-warning for the example. The research is for the sake of providing dynamic and multidimensional technical means for emergency management system realization, and providing helpful ideas for the pre-warning system development which related with the geographical position closely.
