Landscape change monitoring based on a large a suite of ecological and geomorphological processes occurring across broad spatial scales Purpose: LandTrendr has come to refer to the suite of change-detection algorithms which tracks the spectral trajectory of Landsat pixels through time. The main steps in the LandTrendr process include processing Landsat imagery,then smoothing the spectral index signature of each pixel into coherent segments describing periods of stability or change. The primary outputs from LandTrendr are the year of change onset, the duration of change, and the magnitude of the change. Objectives: 1) Create a polygon layer with a minimum patch size of r 0.8 ha (2.5 acres) representing landscape changes of less than 4 years in duration. This will be created from LandTrendr outputs that have been processed into patches based on the year of onset and duration of change. 2) Determine change agent. A Random Forests classification model will be applied to label polygons by their change type. The eight change types of interest are: Avalanches, Clearings, Development, Fires, Mass Movements, Progressive Defoliation, Riparian, and Tree Toppling. Field and office validation of the labeled results is conducted to determine the accuracy of the Random Forest classification. For each park in the NCCN, data analysis and reporting will occur every three years and trends will be reported every 10 years. With the development of the Landscape Change Monitoring Protocol, NCCN represents one of the first natural resource management agencies in the country to use the dense Landsat time-series data for monitoring.
