| Abstract: | The mathematic modle for surveying surface firebehavior by use of aerophotogrammetry anddigital terrain model(DTM)was studied and discussed.Some new mathematic models for survey-ing thd velocity of forest fire spread,the height of fire,the area,girth of burnt zone were pre-sented.These model are the foundation theory for surveying the surface fire behavior on real-time. |
