Wooded extent and foliage projective cover -...

Foliage Projective Cover (FPC) is the percentage of ground area occupied by the vertical projection of foliage. The Remote Sensing Centre FPC mapping is based on an automated decision tree classification technique applied to dry season (May to October) Landsat-5 TM, Landsat-7 ETM and Landsat-8 OLI imagery for the period 1988-2013. The wooded extent product has a nominal accuracy of 85%. The field data used to calibrate the imagery/FPC relationship was mostly collected over the period 1996-1999. Corrections have been applied to remove errors due to topographic effects, cloud, cloud shadow, water, cropping, and regrowth following clearing. Some errors may remain. The product was generated from WRS-2 path/row scenes obtained from the United States Geological Survey (USGS). While some land cover change may be detected in the FPC processing, this product is not designed to generate clearing or regrowth following clearing layers, and should not be used to assess clearing or be compared with previous years for change monitoring. The Statewide Landcover and Trees Study (SLATS) produces accurate clearing layers for this purpose.
