CWT-LTER Data Set Summary

Accession: 5001 CWT Research Theme: Disturbance and Land Use
Contributor: Virgil E. Johnson
Title: Southern Appalachia NLCD Landcover
Abstract: Satellite imagery (mosaicked +ETM and TM imagery satellite imagery from late 2005 through mid-2006) were downloaded from the web for spring, leafoff, and leafon conditions (Fig. 2). From these layers we derived tasseled cap bands 1,2,3. Other data used included digital elevation models (DEMs), DEM slope calculations, and 2006 NAPP DOQQs (used for training sets). We classified imagery using classification and regression tree method (CART) using a combination of Landsat TM imagery and ancillary data. The specific CART program used was See5, which implements a gain ratio criterion in tree development and pruning (Quinlan, 1993). We used boosting and cross-validation to improve classification accuracy (boosting) and estimate accuracy (cross-validation).
