*** Notice *** The CIO performs regular maintenance updates on our servers on Friday nights between 9 and 11 pm EST. Online tools may be briefly unavailable during the maintenance window. Thank you for your understanding.
Nov 4, 2021: Warning! ATIM reports using either County, Unit, or NFS Administrative Forest Code ALP as the column format selection will result in inaccurate results in both the Excel and XML output. This issue is not present with HTML output..
Oct 21, 2021: Warning! FIA’s Alaska inventory is not spatially complete and FIA inventory unit boundaries do not follow Alaska’s borough and census area boundaries or ecoregions. Therefore, estimates and statistics based on these spatial features may be misleading. For more information, please refer to the supporting documentation here.
Sep 27, 2021: There is a known issue with EVALIDator and the EVALIDator API regarding temporal selections in change reports. If users select Inventory Year for the page, row or column, only the Current temporal option is recognized and used for reports even if a different temporal selection is made.
Jun 14, 2021: EVALIDator continues to experience stability issues. The CIO has determined that the server on which EVALIDator is currently running is unstable, causing intermittent unavailability. If you are unable to access EVALIDator, please use DATIM. DATIM provides the same capabilities as EVALIDator, as well as additional features that users will likely find useful.
Aug 6, 2020: We are in the process of updating periodic remeasurement datasets for some states. You can find the list of affected states and their associated evaluation groups along with supporting documentation here.
