Seventy-two of these points were randomly selected and stratified using a random cluster method to constrain the points to areas where high resolution imagery was available. The sampling scheme included a range of conifer species, health, and elevation range. None of these points were used as training sites for image classification. Six additional sample points were obtained through the collection and assessment of field data. Purpose: To show the location of accuracy assessment points that were used to validate the accuracy of the 2008 conifer health classification for Colorado project. Supplemental_Information: Additional method and background information to create these data are described fully within the pamphlet accompanying the map. It is strongly suggested that the user consult the text and be familiar with limitations in the methodology when using this data set.

Logical_Consistency_Report: There are no duplicate points present in this dataset. Completeness_Report: This dataset includes all the accuracy assessment points that were visited for the 2008 conifer health classification project for Colorado. Lineage: Process_Step: Process_Description: Based on field observations and remote sensing theory, it was determined that if an area approximately the size of a pixel contained 20 percent or greater visibly dead trees, that pixel would be classified as "unhealthy" and coded to the value of "1" in the Field_Ver attribute. The number of actual trees dead varied depending on the density and type of tree species in that area. A value of "2" or "healthy" was given for a pixel area that contained less than 20 percent dead trees. An additional value of "0" was used to describe an area where no call was made, usually due to clouds or inadequate image coverage.
