Description:
Abstract:
The National Land Cover Database 2011 (NLCD2011) percent tree canopy cover layer (TCC 2011) was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium (www.mrlc.gov). The MRLC Consortium is a partnership of federal agencies, consisting of the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service, the U.S. Forest Service, the National Park Service, the U.S. Fish and Wildlife Service, the Bureau of Land Management, NASA, and the U.S. Army Corps of Engineers. One of the primary goals of the project was to generate a current, consistent, and seamless national land cover, percent tree canopy cover (PTCC), and percent impervious cover at medium spatial resolution. Puerto Rico and the US Virgin Islands TCC 2011 was produced by the USDA Forest Service Remote Sensing Applications Center (RSAC). For the PTCC layer, the pixel values range from 0 to 100 percent; 255 represents the background value. The PTCC layer was produced using random forest. PTCC values that were less than a calculated uncertainty were set to zero. The PTCC has data gaps due to persistent clouds/shadows in the Landsat images used for modeling. These data gaps are represented by the number 127.
Purpose:
The goal of this project is to provide the Nation with complete, current and consistent public domain information on its tree canopy cover.

Attribute_Accuracy_Report:
No formal independent accuracy assessment of the Puerto Rico and the US Virgin Islands TCC 2011 has been made. The random forest regression algorithm (Breiman 2001; Liaw and Wiener 2002; Cutler et al. 2007) employed in the Puerto Rico and the US Virgin Islands TCC 2011 mapping calculates the mean of squared residuals along with percent variability explained by the model for assessing prediction reliability. The random forest models consisted of 500 decision trees, which were used to determine the final response value. The response of each tree depended on a randomly chosen subset of predictor variables chosen independently (with replacement) for evaluation by that tree. The responses of the trees were averaged to obtain an estimate of the dependent variable. The standard error is the square root of the variance of the estimates given by all trees. A summary of the random forest model is available in the supplemental metadata.

Process_Description:
Creation of the Puerto Rico and the US Virgin Islands TCC 2011 Percent Tree Canopy Cover (PTCC), cartographic version (main process). The cartographic version of the PTCC product is a filtered version of the corresponding analytic product, in which values less than a calculated uncertainty have been set to zero. In essence, the filtering process reduces errors of commission by eliminating values that are not significantly different from zero. A threshold value was determined using data from 500 runs of the Random Forest™ algorithm on bootstrap samples. From these data, t-statistics were calculated. The t-statistic at the 95th interval was selected as the threshold value, which was 2.25. To create the cartographic layer, the product of the t-statistic threshold value and the standard error from the analytical layer was subtracted from the analytical PTCC value. If the result was less than 0, the PTCC value for that pixel was set to zero in the cartographic layer; otherwise, the PTCC value from the analytical layer was used.
