Three words: LANDFIRE 2008 “Refresh.”
That is, many of LANDFIRE’s 20-plus spatial data layers have been improved or updated to be current as of 2008.
These maps show the vegetation disturbance information used to update LANDFIRE maps to circa 2008. Many of these disturbance events were submitted by the LANDFIRE user community to help keep LANDFIRE data current.
To create the LF 2008 “Refresh” products, LANDFIRE made a number of improvements to its products, many based on user feedback. Changes include:
- Improved forest height and cover mapping,
- Remapping of Biophysical Settings in some areas using more detailed soils information,
- Reclassification of fire behavior fuel model layers in protected landscapes to reflect situations where some agricultural and urban lands are managed as natural lands or are in a burnable type,
- Updated urban and agricultural mapping using details from the National Land Cover Dataset, National Agriculture Statistics Service and other data sets.
- Vegetation Condition Class information mapped for Alaska and Hawaii,
- Application of succession information to “grow” or transition vegetation from circa 2001 vegetation to circa 2008, and
- Incorporation of 1999 – 2008 disturbance and treatment information.
As always, these data are available for free on the Data Distribution Site and through the LANDFIRE Data Access Tool.
LANDFIRE is now working on its 2010 updated maps which are scheduled to be released in 2013. Similar to its 2008 "Refresh" counterpart, the LF 2010 products will incorporate succession and disturbance information as well as user feedback. LANDFIRE needs you. LANDFIRE's maps are driven by plot data and disturbance/treatment information (typically GIS polygon data), much of which is provided by users.
