Mapping of deadwood on the ground and calculation of its volume

Each piece of deadwood is represented by a line leading lengthwise through an axis and connecting all vertices (base, all break points and end) of the deadwood and by a polygon circumscribing the deadwood in a horizontal projection. The polygon is created by connecting the base and the top (or optionally at each break point) of the deadwood.

Deadwood can e defined by two end points (mostly conifers) and additionally by a number of break points (broadleaf trees).

The length and volume of each deadwood is calculated automatically. Field-Map also stores information about the Z co-ordinates of break points, so the volume is always calculated in 3D projection (this is particularly important on the slope, where “2D volume” in underestimating)

Field-Map user can choose whether to calculate the total deadwood volume or the volume for part of deadwood, which is lying within a plot boundary (volume inside the plot).
