Change Detection product for Mission Trails Regional Park (MTRP) generated using difference image overlay technique.

PS: Images show two burn areas before and after the fires between 1998 and 1999.

The product above is a change vector classification illustrated with band 3 of the 1999 ADAR image as a backdrop. The red, blue, yellow, and green colors indicate the following categories of change, respectively: green vegetation decrease (due to phenological differences), complete vegetation loss (due to fire), litter decrease/soil increase (due to fire and recreation impacts), and green vegetation increase (due to increased vigor of mustard plants and riparian vegetation). The hilltops on either side of Mission Gorge road demonstrate change artifacts associated with misregistration between the multitemporal ADAR imagery.
