Overstated volumes from "pushing" the point

"Pushing" a prism point by failing to keep the prism over the sample point will cause volume to be overstated. The amount of overstatement differs by tree dbh, BAF, and distance the prism is from where it should be. Large dbh's are less overstated than small dbh's, large BAFs cau...

Summary:"Pushing" a prism point by failing to keep the prism over the sample point will cause volume to be overstated. The amount of overstatement differs by tree dbh, BAF, and distance the prism is from where it should be. Large dbh's are less overstated than small dbh's, large BAFs cause more overstatement than small BAFs. Large errors in prism position can cause overstatements of 7% to 19%; small errors can cause overstatements of 2% to 4%
