  2. NACP NAFD Project: Forest Disturbance History from Landsat, 1986-2010

The North American Forest Dynamics Project (NAFD) products provided in this data set consist of 25 annual and two time-integrated forest disturbance maps for the conterminous United States (CONUS) for the period 1986-2010. Each annual map has classified pixels showing water, no forest cover and forest cover present, and forest disturbances that occurred in that year. The time-integrated maps are similarly classified, but over the entire 1986-2010 period with the first and last forest disturbance years identified and provided as separate maps. Maps have a nominal spatial resolution of 30 m, with forest disturbances mapped at an annual time step. These products are referred to as the NAFD-NEX data set to acknowledge the collaboration with the supercomputing facilities at the NASA Ames Research Center provided by the NASA Earth Exchange (NEX, Nemani et al. 2011) to process the large volume of Landsat imagery used in this study.
