The trails data set is represented by six individual layers in WFDSS:
The data for each of these layers was compiled categorically and then each individual layer was extracted from the resulting national layer. Minor edits were performed on the data to ensure a consistent format across layers. The attributes of each source data set were manipulated to ensure that the trail name and type were included for each line segment. The data were dissolved in such a way as to ensure that a consistent segment length was maintained. This will ensure that the data perform well within the application when copying or downloading a segment of line.
The trails data are not available for download/copy however, you can view feature information for these layers using the identify button on the maps.
The overall accuracy of these data varies across the layers and is due to the fact that each data set was created at various scales. These data are intended to be used for strategic planning only and should not be used to make tactical decisions on the ground. Always verify specific trail locations with local knowledge.

The WFDSS application is "data rich". It requires data which is spatially oriented and graphically displays information to support wildland fire and other natural resource decisions. Due to the type and number of interagency spatial data sets required in April 2009 an interagency GIS Team was formed to provide data support for WFDSS. This Team is responsible for acquiring, consolidating, and validating their agency spatial and tabular data. In addition this team developed and maintained communications among local, regional, and national agency personnel to improve the collection process and provide explicit guidance on data needs. The members of the WFDSS GIS Team are:
