There is one data set for each year representing an aggregate of the approximate peak of the growing season (around August). The data was created using a sophisticated algorithm called LandTrendr. The visualization zooms into the Portland area showing different types of land such as agricultural, urban, and forests. We move south to a region that was evergreen forest for a number of years (blue), then was clear cut in 1999 (orange), then began to regrow (yellow). A graph shows the history for a particular location in the clearcut as the years repeat. The dots represent the original data from Landsat; and, the line represents LandTrendr analysis. Subsequent sequences examine the effects of insect infestations in the Three Sisters region, southwest of Mt. Hood, and east of Mt. Rainier. The final piece demonstrates the visible differences in management policy between forests inside and outside of National Park Service boundaries.
