Agencies that participated on the Wisconsin LTA Project Team include the Wisconsin Department of Natural Resources, the Natural Resources Conservation Service, the USDA Forest Service (State and Private Forestry and National Forests), the Wisconsin County Forest Association, the University of Wisconsin (at Madison and Stevens Point), Menominee Tribal Enterprise, and the Wisconsin Geological and Natural History Survey.
The LTA delineations in the NHFEU dataset are presented as an ArcInfo Region feature class ("region.lta"). For a detailed explanation of the contents of the LTA dataset, processing steps used in its development, and guidelines for use of hte LTA dataset information, refer to the following documentation, available upon request from the Wisconsin DNR (see contact information): "LTA Data Dictionary"; "LTA Processing Procedure"; "LTA User's Guide".
For the digital creation of LTA lines, a process was developed with standard data capture and QA/QC procedures. Coplete detailed information can be reviewed in the "LTA Processing" documentation (see Supplemental Information).
Periodically the ArcInfo feature class "region.lta" is converted to polygon shapefile format distribution and use.
