Quality Accuracy assessment procedures fall into three steps: 1) sample selection 2)
labeling of reference and map sites and 3) generation of error matrices and
estimates of accuracy. A population of vegetation polygons 5 acres or greater
from which to sample was generated from the unclassified Landsat TM imagery
using Image Segmentation. The resulting ... View entire text
