The purpose of this data is to provide boundary information for Humboldt-Toiyabe National Forest for use by Forest Service resource specialists, project planners, GIS specialists and others. Attribute values that describe these data are stored as spatial attributes. PROCESS: Administrative Forest boundary dataset was used as a starting point for this map. Subdivisions that are not based on exterior boundaries were created using feature information in other, current GIS datasets. The maps produced using this dataset may not exactly match the original Forest Plan map set due to boundary changes, cartographic adjustments, and land status changes. User must exercise caution regarding the spatial accuracy of these data. The source scale of the original maps was 1:126720, the features used to recreate the data were 1:24000. Data may be viewed and used by any and all entities upon request. However, data should not be changed or modified by anyone other than the originating National Forest. The USFS does not guarantee the accuracy of this data. Source.
