    dct:description """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).""" ;
