Path Forward
Overview of DATIM: Vision
• Improve NFS monitoring designs and data analyses
by developing nationally consistent tools – Design
Tool (DTIM) and Analytical Tools (ATIM)
•
Initial focus on vegetation monitoring, but expand to
other resources that use plot-based sampling
•
While the tools will be publicly accessible, they were
initially designed with NFS in mind, which opens up
use of FIA data to its biggest partner as the new
Planning Rule is being implemented.
Overview of DATIM: History
•
Renate Bush and I submitted proposal to evaluate
the development of a Design Tool (DTIM) and an
Analytical Tool (ATIM) in 2007.
•
Ken Brewer led the Core Team in their development
of the requirements documents which were
completed Feb. 2009.
•
Starting in FY09, have received about $450K/year
from WO (IRDB from EMC) – total is $2,216K.
•
UNLV & regional developers were then engaged.
Overview of DATIM: Status
•
Soon became obvious that the Compiler and
DataMart were needed.
•
The Spatial Intersection Tool was added based on
idea from Wisconsin DNR (NIMAC project).
•
We are in testing for Phase 1 of development; it is
being deployed at NITC, and will receive Patch 1
soon.
•
Phase 2 should be developed and tested this
calendar year. Hope to go outside firewall by end of
2014.

Design Tool for Inventory &
Monitoring (DTIM)
•
Helps customers work through their monitoring
information needs: objectives, questions and
metrics.
•
“Expert” modules can be created for different
applications, such as for State intensification, the new
Planning Rule and by NFS Region.
•
•
Working with FAO to create an international module
Helps design the analytical tables
Design Tool for Inventory &
Monitoring (DTIM)
•
Helps determine the sample sizes (level of
intensification) needed to meet precision
requirements
•
Helps build cost-effective sampling designs to avoid
under-sampling, oversampling, or attempting to
monitoring attributes which are too expensive to
monitor with sufficient precision (so don’t
overpromise)

DataMart & Compiler
•
Developed the DataMart to store DATIM data and
metadata because FSVeg is optimized for flexible
data storage but not for use by analytical tools
•
First non-spatial database in the Enterprise Data
Warehouse (EDW)
•
•
Load data from FSVeg or FIA’s NIMS
Run Compiler to add NFS computed fields using FVS
routines, such as Dominance Class, habitat types,
volume, and biomass. Regions can customize.

Analytical Tool for Inventory &
Monitoring (ATIM)
•
ATIM is used to answer the monitoring questions
posed in DTIM using the FIA or Regional inventory
data in the DataMart.
•
ATIM (like EVALIDator or FIDO) allows the user to
pick the area of interest, the metric to estimate, and
the classes to group the results by (rows and
columns). It also provides the sampling errors
(confidence intervals) using Green Book or
bootstrapping.
•
Analyses can be further refined by filtering the data to
focus on the subpopulation or domains of interest.
•
Users can make snapshot of the data.

Spatial Intersection Tool
•
SIT allows the user to optionally identify the area of
interest using GIS (ArcGIS on PC or on the server)
•
SIT can return map attributes to ATIM to use as
grouping classes and data filters
•
•
Users can specify different stratification layers
•
SIT provides a powerful new way to analyze the data
– saving hours.
Working with SDS folks on encryption method so that
users can analyze based on actual coordinates
without being able to find out the coordinates.
Spatial Intersection Tool (SIT)
•
Can be used as an ArcGIS add-in or via CITRIX
