Q. What are the satellite imagery dates for the existing vegetation products?
LANDFIRE National (LF c2001) existing vegetation products portray vegetation composition and structure conditions circa 2001. The time period is determined by the average date of Landsat satellite imagery acquisition used for the original mapping, which occurred from 2000 to 2002. Subsequent versions (LF 2001, LF 2008, LF 2010, LF 2012, and LF 2014) used National as a starting point for data processing. Disturbances mapped in updated versions beyond National used imagery from 1999-2014 where the imagery year corresponds to the disturbance year.
