Abstract
A tool is triangular in shape and made of a clear plexi-glass. The tool contains two types of rate of spread scales, historical and real time. The historical rate of spread scale is based upon previous large-scale brushfires, while the real time scale utilizes GPS technology. The historical rate of spread scale is designed to address two brush fire environments. These environments are a brush fire occurring under Red Flag conditions and a brush fire occurring under Non-Red Flag conditions, and references are placed on the tool at each 30-minute time zone.
Claims29
A rate of spread tool comprising:
- a geometric plotting element;
- at least one historical rate of spread scale and at least one real time rate of spread scale, related on the surface of the element, wherein, in use, the tool is oriented so that the scales on the tool is readable for a moving fire depicted on a map.
A rate of spread tool comprising:
- a selected geometrically shaped element;
- at least one historical rate of spread scale and at least one real time rate of spread scale, related on the surface of the element;
- and
- and the real time scale utilizes GPS technology.
A rate of spread tool comprising:
- a geometric plotting element;
- at least one type of rate of spread scale, selectively being at least one of an historical time and real time, related on the surface of the element, wherein, in use, the tool is oriented so that the scales on the tool is readable for a moving fire depicted on a map;
- and
- wherein said rate of spread tool is an essentially triangular shape.
