Steven Sobieszczyk 2011 raster digital data http://water.usgs.gov/lookup/getspatial?fannoCk_ndvi_09 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). This data set was developed as part of an USGS carbon study that examines sources of carbon-rich organic material along Fanno Creek. In order to quantify how much material enters the stream, the different river and floodplain features needed to be defined. In this data set the vegetative cover was defined in order to represent the location and extent of vegetation available within the Fanno Creek floodplain.

The observed agreement was 89%, chance agreement was 62%, and the Kappa coefficient was 70%. NAIP imagery from 2009 was used to verify that the mapping was reasonable. Data set manually derived from 0.5-meter resolution aerial imagery. Data are complete. Comparable to NAIP imagery, within six meters of ground control points.
