Mapbook atlas of riparian vegetation for 2006, 2016, and the change between years

Models of riparian vegetation were created by digital image sampling to collect environmental response data. National Agriculture Imagery Program (NAIP) imagery at the time step and a scripted Google Earth Engine image visualization and data collection interface was used to ocularly interpret the presence and absence of riparian vegetation. Final models were applied using Landsat composite imagery and associated vegetation indices with the digitally collected occurrence locations. The random forest algorithm was used within Google Earth Engine to develop models for 2006 and 2016 by Environmental Protection Agency (EPA) ecoregion III. Models were constrained to valley bottoms across the Colorado River Basin. A change map was created by differencing 2006 and 2016 results for a gain, loss and persistence map. Detailed methods can be found in Woodward et al. (In prep).
