This element stores the azimuth of the x-axis used to describe the relative coordinate system for plot shape (dsgpoly) and other spatial information about the plot. Typically the azimuth is parallel to the long axis of the plot (in the case of a rectangle).
This field is a text string containing the points circumscribing a plot area. These points are anticipated to have been collected using tapes, GPS, or calculated from the plot shape and area. Points are X-Y coordinates in m relative to plot origin.
Total area of the plot in m2. If many subplots, this area includes the subplots and the interstitial space. RESERVED VALUE: -1 is used to indicate that the plot had no boundaries.
The extent of this community occurrence in relation to the plot size: very extensive (>1000x plot), extensive (>100x plot), large (10-100x plot), small (3-10x plot), very small (1-3x plot).
