A problem was recently identified with the Fire Regime Condition Class Departure Index (dep) layer for Mapping Zone 99. Processing of this layer for Zone 99 was incomplete, leaving many of the pixels unassigned. Users are advised to delete any local copies of this layer for Zone 99 and download the updated version as of November 17, 2008. We regret any inconvenience this may have caused. posted 22-OCT-08 | Zone 99: A problem was identified with the Fire Regime Condition Class (frcc) layer... |
A problem was recently identified with the Fire Regime Condition Class (frcc) layer for mapping zone 99. FRCC processing for zone 99 was incomplete leaving many of the pixels unassigned. Users are advised to delete any local copies of this layer for zone 99 and download the updated version as of October 20, 2008. We regret any inconvenience this may have caused. posted 27-SEP-07 | FRCC and FRCC Departure Index data products now available... |
External review has been completed, and these data products are now available on the National Map LANDFIRE. posted 03-JAN-07 | Zone 13: A problem was identified with the Succession Classes layer... |
A problem was recently identified with the Succession Class layer from Mapping Zone 13. Small residual errors from data processing resulted in a slight difference in the Biophysical Setting layer used to create the Succession Class layer as well as the version of the Biophysical Setting layer released for download. These differences could result in errors in calculating local measurements of Fire Regime Condition Class with the FRCC Mapping Tool. Customers are advised to delete any local copies of this Succession Class layer downloaded prior to January 1, 2007 and download the current version. We regret any inconvenience this may have caused.

A minor problem was recently identified with the Biophysical Settings layer for Mapping Zone 44. Users are advised to delete any local copies of this layer downloaded prior to October 20, 2008 and download the current version. We regret any inconvenience this may have caused. posted 22-OCT-08 | Zones 15, 18, & 28: The Environmental Site Potential (esp) layer was updated... |
The Environmental Site Potential layer for mapping zones 15, 18, and 28 was updated October 20, 2008. Users are encouraged to use this updated version of the fuel suite. posted 20-MAY-08 | Zones 25, 26, 27, 29, 30, 33, 34, 37, 44, 45, 55, 56, 58, and 98: A problem was identified with the relative age setting in the VDDT models... |
Relative age was not set correctly in the VDDT models in the following eastern zones when they were first made available for download from www.landfire.gov: 25, 26, 27, 29, 30, 33, 34, 37, 44, 45, 55, 56, 58, and 98. Relative age, according to LANDFIRE modeling rules, should be set to the inverse of the end age of the class (for example, if the class end age is 10 and relative age is used, it should be set to -10). In the aforementioned zones, relative age was set to the class end age rather than the inverse of the class end age. In some cases, an incorrect relative age setting could change the model results. The LANDFIRE team has corrected the relative age issue and redelivered corrected files. For zone 25 a new version of the model description document was released to correct inaccurate descriptive information related to this issue. For all other zones, only the VDDT database was changed. The error in the relative age setting did not affect any of the mapped products. Customers are advised to delete any local version 1 databases (that is, those that have "v1" in the file name) they may have downloaded and replace them with the version 2 databases (those that have "v2" in the file name) currently available from the LANDFIRE website. posted 18-SEP-07 | Zone 37: A problem was identified with the following layers... |
A minor problem was recently identified with the Aspect, Elevation, Slope, Existing Vegetation Cover, Existing Vegetation Height, and Existing Vegetation Type layers for mapping zone 37. While affected acreage is very small, users are advised to delete any local copies of these six layers downloaded prior to September 6, 2007 and download the updated versions as of September 18, 2007. We regret any inconvenience this may have caused.
