Normalized Difference Vegetation Index for Fanno Creek, Oregon
Fanno Creek is a tributary to the Tualatin River and flows though parts of the southwest Portland
metropolitan area. The stream is heavily influenced by urban runoff and shows characteristic
flashy streamflow and poor water quality commonly associated with urban streams. This data
set represents the Normalized Difference Vegetation Index (NDVI), or "greenness"
of the Fanno Creek floodplain study area. Aerial photography was used to isolate areas of
vegetation based on comparing different bandwidths within the imagery. In this case, the NDVI
is calculated as the quotient of the near infrared band minus the red band divided by the near
infared plus the red band. NDVI = (NIR - R)/(NIR + R).
