<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset contains all the road centerlines in the Greater Yellowstone Area (GYA).

Additionally, the North Entrance Road (U.S. Highway 89) line was edited in April, 2025 to reflect the road's realignment following the June, 2022 flooding along the Gardner River. The WSGS has not formally reviewed or quality-controlled these data; users are encouraged to consult the original data source.</SPAN></P></DIV></DIV></DIV>
This dataset will provide a uniform, seamless road centerline network to the extent of the GYA.

Full line topology exists for this layer as verified by
Arc/info v8. The coverage has not been edited since the last BUILD
function.
This layer, in reality, represents a fraction of all roads
in the GYA. It leaves out many secondary highways, connecting
highways, and local roads.
The transportation data from each DLG dataset were
converted to ARC/INFO coverages using the SDTS2COV.AML. All quad
tiles were then appended into one coverage for each theme: roads,
railroads, and pipe and transmission lines.

These road arcs replaced those in the DLGs that covered
Yellowstone National Park. Thesse data were GPS'd, therefore
their accuracy (sub-meter) is much better than the 1:100,000 DLGs.

This layer was used to clip out the DLGs within
Yellowstone National Park so they could be replaced with more
accurate data (All Roads of Yellowstone National Park, Wyoming,

The west and east side of each 1:100k quad was converted
to ARC/INFO using the sdts2cov.aml, using the -layers 1..12-define
arguments. The master data dictionary from the USGS was installed.
1999-07-31
The append command was used to join the quads together.
The border arcs of each tile were deleted by selecting features
with entity-label = ' '. The matchnode command was then
run, with a match tolerance of 8.0.
1999-07-31
The coverage was then built with the line option. In most
cases, the arc attribute table needed to be updated to include ALL
items used in the GYA, so that all AAT's matched.
1999-07-31
A few DLG's had missing attributes. Border arcs in
these cases had to be manually deleted.
1999-07-31
Route_desc field was added, classifying class 1 roads as
"Primary routes," class 2 roads as "Secondary
routes," class 3 roads as "Roads or streets," and
class 4 roads as "Class 4 Roads or Streets," while other
descriptions from the entity_def field remained the same.
2000-06-14
Most original fields were dropped (NAME, TYPE, STREET,
ROUTE_TYPE, ROUTE_DESCRIP, ARBITRARY_EXT, RELATION_TO_GRO,
VERTICAL_RELATI, OPERATIONAL_STA, ACCESS_RESTRICT, OLD_RAILROAD_GR,
WITH_RAILROAD, COVERED, HISTORICAL, LIMITED_ACCESS, PHOTOREVISED,
LANES, ROAD_WIDTH, BEST_ESTIMATE, ROUTE_TYPE1, ROUTE_TYPE2,
ROUTE_TYPE3, ROUTE_TYPE4, COINCIDENT1, COINCIDENT2) due to lack of
descriptive data in fields.
2000-06-15
In arcedit, those arcs with no attribute information were
coded for primary roads only.
