Welcome to DATIM!

The Design and Analysis Toolkit for Inventory and Monitoring (DATIM) is a suite of software tools used for designing inventory and monitoring programs and analyzing the results of those programs.

News and Alerts:

5/8/2024 6:11:27 PM CT: ArcGIS Pro 3.3 is now available and with it comes a new version of SIT Pro that is not backwards compatible. While the Forest Service moves away from ArcGIS Pro 3.2, users who wish to work with SIT Pro in ArcGIS Pro 3.3 may request the new addin from us directly through the Contact Us page. The SIT Pro download link and T-Drive directory listed on the SIT page will only work on ArcGIS Pro 3.2 or below.
5/8/2024 5:13:31 PM CT: From now on, all DATIM User Guides will be hosted on the new FIA Tools and Data webpage. Please note that the DATIM version 19.0 User Guides will be uploaded soon. Thank you for your patience.
3/26/2024 12:21:24 PM CT: User accounts are required to be locked (inactivated) after 60 days of inactivity. Locked accounts will usually trigger an "eAuthNotAuthenticated" or "eAuth authentication is not supported by this server" error. If your account has been locked, you can request reactivation by reaching out to us through our Contact Us page.
1/18/2024 11:05:46 AM CT: For spatial intersections, DATIM is transitioning away from ArcMap and towards ArcGIS Pro. SIT will be available for both applications through September 2024, afterward the ArcMap addin will be decommissioned and only the ArcGIS Pro addin will be available. If you have any questions, please reach out to us through the Contact Us form.
6/1/2023 4:17:38 PM CT: 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 FIA Tools and Data.
3/10/2022 12:47:29 PM CT: Users should be aware that the creation of a custom analysis with custom estimation units will not work if a user selects more than one forest. The analysis may get created but results will be spurious. Custom estimation unit creation is in BETA and future efforts will accommodate this need.

DATIM Tools

With the exception of the Spatial Intersection Tool (SIT) and My Dashboard (Saved Objects), you do not need to login to use DATIM. To access advanced features, such as saving your work to the DATIM server, please login.

To get started, select one of the tools below.

Analysis Tool for Inventory and Monitoring (ATIM)
Generate reports of estimate summary attributes for an area of interest and survey year. Users can select existing analysis datasets for use in reporting. Advanced users (login required) can create new analysis datasets.

Design Tool for Inventory and Monitoring (DTIM)
Design an inventory and monitoring plan to address specific information needs by identifying objectives, questions and metrics.

Spatial Intersection Tool (SIT)
Perform spatial intersections between plot-based data and user-selected geospatial layers, and return map attributes for use in ATIM summaries.

My Dashboard (Saved Objects)
Access and manage your custom collection of ATIM reports and analyses, SIT attributes, and DTIM projects. Depending on the object type, you can view, edit, run, or share your custom objects with other users. You can also access custom objects shared with you by other users.
