LTD is being updated, and the version available with ArcFuels is not the most current. Please contact Alan Ager (aager@fs.fed.us) for the most current version and support for LTD.
The LTD program is a multicriteria spatial prioritization and optimization system to help design and explore landscape fuel treatment scenarios. The program fills a gap in the fuel treatment planning process between fire model programs such as FlamMap and planning systems such as ArcFuels10, by providing a systematic way of planning spatially explicit fuel treatments. The LTD uses inputs on spatial treatment objectives, activity constraints, and treatment thresholds, then identifies optimal fuel treatment locations with respect to the input parameters.
Example LTD treatment solution, in which the lighter shade within each treatment block (1-4) is marked as needing treatment.
The input data represent polygons that are attributed with information about expected fire behavior and the polygon’s overall contribution to one or more landscape management objectives. Four types of output files are generated with each run: (1) a text file with all the input data with treatment locations indicated, (2) a summary text file of input parameters and output results, (3) a results comma separated file with the input parameters and output results, and (4) a shapefile with an attribute table that identifies patch locations and stands selected for treatments.
The Landscape Treatment Designer form is available when the LTD program is downloaded and linked via the Edit Project Settings form.
For more detailed information about the LTD, refer to the General Technical Report (GTR) by Ager et al. 2012 or visit the program Web site.
