摘要：

Equations are provided to permit forest inventory specialists to quantitatively estimate the total field inventory travel distance, and thus time, based solely on inputs of property size, the number of inventory samples desired, and the type of systematic grid employed. Total inventory travel time is estimated for square and varying rectangular grid spacings for property sizes from 100 to 10,000 ac to estimate the time savings for rectangular grids over square grid patterns for the same number of inventory samples.
