Combining the the ArcObjects COM component with Visual Basic6.0 this thesis ArcGIS8.1 In conclusion, forest fire fighting system based on the use of COM programming ideas and methods , design -based geographic information system (Geographic Information forest Fire Suppression system, referred to as GIS) decision support system. Basic GIS functions , the spread of forest fires , fire suppression path selection, three-dimensional displays , the realization of the stop-gap plan management decision-making to provide strong support for putting out the fire commander . The main contents and conclusions of this study are as follows : ( 1 ) the basic geographical information system functions . Integration of putting out the fire commanders are concerned about the number of GIS functions , such as queries , zoom , roaming , measurement , output ; ② simulation of forest fire spread . Forest fire spread simulation decision support on the basis of the system learn from Rothermel model based on the proposed model is suitable for the local forest fire spread simulation of forest fire spread on the GIS platform ; ( 3 ) the optimum fire suppression path choice. Forest areas natural conditions are very complex , and most of the area and there is no road access , the system of putting out the fire crew and cars in different road conditions prevailing on the road speed and slope and vegetation obstruction of fire suppression team quantitative calculation was Firefighting commander concern under different conditions between the starting point and destination of the optimal path and the time required ; ④ dimensional display . Each layer in three - dimensional conditions display , roaming , query , create the most intuitive judgment : ⑤ stop-gap plan management for putting out the fire commanders . Database management program under the assumption that the fire suppression and fire suppression programs under various practical conditions . Provide an important basis for decision-making through the development of the system , will be putting out the fire commanders , will play an important role in the fire suppression process .
