True versus perturbed forest inventory plot locations for modeling : a simulation study

  title={True versus perturbed forest inventory plot locations for modeling : a simulation study},
  author={John W. Coulston and Kurt H. Riitters and Ronald E. McRoberts and Greg A. Reams and William D. Smith},
USDA Forest Service Forest Inventory and Analysis plot information is widely used for timber inventories, forest health assessments, and environmental risk analyses. With few exceptions, true plot locations are not revealed; the plot coordinates are manipulated to obscure the location of field plots and thereby preserve plot integrity. The influence of perturbed plot locations on the development and accuracy of statistical models is unknown. We tested the hypothesis that the influence is… CONTINUE READING
