1. Boundaries for the selected SMA were digitized directly from 1:100,000 scale Surface Management Status Maps published by the Bureau of Land Management.
2. Boundaries for the selected SMA were manually transcribed from a 1:126,720 scale USFS Management Area Map to the corresponding 1:100,000 scale BLM Surface Management Status Map and digitized.
3. Boundaries for the selected SMA were digitized from a paper overlay that had been manually traced from a USFS 1:24,000 scale stand management map.
4. Boundaries for the selected SMA were digitized directly from 1:24,000 scale blue line reproductions of Wildlife Habitat Management Unit (WHMA) maps developed by the Wyoming Game and Fish Department in Cheyenne, Wyoming.
5. Boundaries for the selected SMA were derived from 1:24,000 scale blue line reproductions of Wildlife Habitat Management AREA (WHMA) maps developed by the Wyoming Game and Fish Department in Cheyenne, Wyoming. The reproduced maps did not contain control points (points of known latitude-longitude) and could not be registered for digitizing. Also, the WHMA boundary was considered to be irregular or non-linear, such as boundaries following rivers. Transcribing irregular boundaries would have introduced considerable positional inaccuracies. Therefore, a data-capture method was developed which consisted of several steps. First, the WHMA boundary was digitized from the blue line map using digitizer units (inches). Second, the digitized boundary was converted to raster format. Third, the rasterized boundary was matched up with the corresponding area within the vector landstat layer and points common to both the rasterized boundary and the landstat layer were identified. Fourth, the CONTROLPOINTS routine within ARC/INFO was used to link common points between the WHMA raster and the vector landstat layer (note: the number of common points varied with WHMA - see blue line map for the number of control points used). Fifth, the WHMA raster was "rubbersheeted" to fit the landstat layer using the ARC/INFO GRIDWARP command. Sixth, the warped WHMA boundary was converted back into a vector format and incorporated into the landstat layer using the ARC/INFO UNION command. Seventh, sliver polygons were removed.
6. Boundaries for the selected SMA were derived from 1:24,000 scale blue line reproductions of Wildlife Habitat Management Unit (WHMA) maps developed by the Wyoming Game and Fish Department in Cheyenne, Wyoming. If the boundary of the SMA consisted of polygons already within the landstat layer, then the SMA was not digitized from the 1:24,000 scale blue-line maps. Instead, the existing landstat polygons were verified using the blue-line maps to ensure correct boundary locations and attributed with the SMA code. The positional accuracy of the WHMA boundaries taken from the landstat layer is recorded as FAIR.as the WHMA boundary was linear in nature, then the WHMA boundary was transcribed onto the corresponding BLM map and digitized. WHMA boundaries done in this manner were adjusted to fit existing linework in the landstat layer. The positional accuracy of the WHMA boundaries taken from the landstat layer is recorded as POOR. 7. Boundaries for the selected SMA were manually transcribed from a small scale map provided in the Resource Management Plan to the corresponding 1:100,000 scale BLM Surface Management Status Maps and digitized.
8. Boundaries for the selected SMA were given to WY-GAP from the Shoshone National Forest of the USFS. The SMA boundary was digitized at the Shoshone Supervisor's Office using 1:24,000 scale base maps.
9. Boundaries for the selected SMA were given to WY-GAP from the National Ecology Research Center (NERC). The SMA boundary was digitized at the NERC Office using 1:24,000 scale base maps.
10. Boundaries for the selected SMA were digitized directly from a map sent by the resource manager that was not included in the resource management document.
11. Boundaries for the selected SMA were derived from a map sent by the resource manager that was not included in the resource management document. The SMA boundary was transcribed to the corresponding 1:100,000 scale BLM Surface Management Status Map and digitized.
12. Boundaries for the selected SMA were derived from USPLS legal descriptions listed in the resource management document.
SMANAME: Primary special managed area
SMANAME2: Where two special managed areas overlap, this identifies
the secondary code of the overlapping area
When a code for the attribute SMA2 exists (not zero), it means that
the special managed area identified by the code overlaps another
special managed area identified by the SMA1 code. The managing agency
coded by SMA1 has primary jurisdiction over the land (there are two
instances: Wind River Indian Reservation (SMA2) with Wyoming Game
and Fish Dept.'s Spence/Moriarity WHMA (SMA1), and the Bighorn National
Recreation Area (SMA2) with Yellowtail WHMA (SMA1),
