Summary

Description

This point file displays the 1543 accuracy assessment (AA) points visited in the summer of 2005 as part of the vegetation mapping project. The points were randomly selected, stratified by the map units used for vegetation mapping and further screened so as not to fall on inaccessible isolated mesa tops or vertical canyon walls. The coordinates were uploaded to Trimble and Garmin hand-held GPS receivers so that ecologists could navigate to them in the field. Some AA points fell on ecotones and two sets of data were recorded on the evenly-split sites. AA points that fell along polygon edges sometimes did not represent the entire polygon well and some AA points fell on small patches of vegetation that were different than the community in the larger polygon. Field photos are associated with each plot.
