Realization of mapping situation of forest fire based on component-GIS.

Programs for the prevention and control of forest fires have evolved in response to the needs to protect lives and property in forested settings,and perceived values of the forest itself.Costs of fire management activities are a concern to managers,and considerable work has attempted to the situation of forest fires mapping.In order to solve the problems existing in the traditional methods of mapping situation of forest fires,including the difficult conversation of map,easy deviation of position,not unanimity of information,the author designed a symbol database suitable for mapping situation of forest fires,including point,line and polygon.Then it realized the function of mapping situation of forest fires based on ArcGIS Engine—a component GIS software,which could provide assistant decision-making scheme for preventing forest fires,and controlling forest fires at the initial stage to cut down the loss as far as possible.
