National Forest Roads

While the bulk of Utah's roads are based on TIGER data, within NF boundaries, TIGER roads were mostly deleted in favor of NF roads. The advantages are many, up to date road existence, more accurate vectors, road numbers and names, road type. In some cases ten TIGER roads were deleted for each NF road added.

The major exception to deleting TIGER roads would be county through roads  If the NF road data did not include these through roads, TIGER data was used. Also, state and federal highways in the TIGER dataset were never deleted.

The forest road dataset allowed for the creation of a unique bold line type for High Clearance roads. So a quick glance at the map can give you much more information about if a road exists and the expected road type. TIGER road data has sparse information as to road type.

While rarer in the NF than TIGER data, orphan roads can and do happen. If you find one and have a track showing the correct linkage, email the data as a .gpx file.
