Improving the line intersect method: Solution that gives better results
Dimitre D. Dimitrov,Ross W. Wein 장전수학회 2008 Advanced Studies in Contemporary Mathematics Vol.16 No.2
The line intersect method (LIM) have been used in estimating the volume per unit area of dead and downed wood in northern forests. The theory and formulae behind the LIM are strengthened so as to give more precise and accurate results. The improved line intersect method (ILIM) introduces a measure of stands specific diameter:length ratio of dead and downed wood that is proven to be a factor of primary importance for the ILIMs precision. Both ILIM and LIM have been tested in the lab and in the forest and the results compared with independently determined volumes per unit area, as well as between each other. In conformity with the theory the ILIM calculates precisely the volume per unit area and gives better accuracy in terms of the narrower standard error intervals. Also in conformity with the theory the LIM was shown to overestimate the volume per unit area and to give lower accuracy in terms of its wider standard error interval. The extent of this overestimation depends on the newly introduced factor, i.e. the stand-specific measure of stands dead and downed wood diameter:length ratio.
