The coordinates for this dataset were collected using Global Positioning System (GPS) technology. Volunteers, using a Trimble ProXL receiver, mapped the trail in the summer of 2001 by walking and driving the trail segments. As this is a "new" trail, some segments did not exist as a feature on the ground, so the volunteers marked the trail with carsonite signs and mapped these segments also. Purpose: To show the location of the Continental Divide National Scenic Trail in the Lander and Rawlins Field Offices. The intended use of all data in the BLM's GIS library is to support diverse activities including planning, management, maintenance, research, and interpretation. This dataset was produced with an intended application at the 1:24,000 scale. Supplemental_Information: The Continental Divide National Scenic Trail was designated by Congress in 1978. The BLM designated an on-the-ground route in the Rawlins and Lander Field Offices in 1999/2000. The Lander and Rawlins Field Offices are located in central and south Wyoming. They include all of Fremont, Carbon, Albany, and Laramie counties, the southwest corner of Natrona County, and portions of Sweetwater and Hot Springs counties.

This procedure enhanced attribute accuracy by reducing attribute-related decision making in the field and minimizing keying errors. Some attributes were generated by the Pathfinder Office software. The outdoor recreation planner verified the attributes for those features that he had personally been to on the ground. The GIS specialist checked all attributes for consistency. Logical_Consistency_Report: Topologically clean dataset. There are no duplicate features present. Arcs were exported from Pathfinder Office into ArcInfo. Arcs were snapped to each other and overshoots were deleted in the ArcEdit module of ArcInfo. The ArcInfo commands INTERSECTERR and NODERRORS were used to identify missing or deviant data. Topology was built using the ArcInfo BUILD command with the "arc" option. Completeness_Report: The entire length of the Continental Divide National Scenic Trail located in Lander and Rawlins Field Offices was mapped. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The data were collected according to an accuracy standard of maintaining a maximum PDOP (Position Dilution of Precision) of 6, while tracking a minimum of 4 SV (space vehicles). These data were differentially corrected and have estimated accuracies in the X and Y direction of 0 to 5 meters. The horizontal positional accuracy was tested by verifying the location of the data on-screen relative to the corresponding 1:24000 USGS DRG (digital raster graphic) or DOQ (Digital Orthophoto Quadrangles) in the same projection and datum.

Source_Contribution: Provided coordinates and attribute data for features Process_Step: Process_Description: During July and August, 2001, two volunteers, Karen and Bill Gahr, walked and drove the Continental Divide Trail segment across Lander Field Office. They used a Trimble ProXL to map the route. In many places the Continental Divide Trail is coincident with such things as county roads, two-tracks, or trails. In other places the Continental Divide Trail went cross-country and had no real on-the-ground features to correspond to. The Gahrs followed the marked route and mapped it with the GPS unit. In addition, they documented the locations of carsonite sign posts that mark the route. A maximum Position Dilution of Precision (PDOP) of 6 was maintained for each set while tracking at least 4 satellites. At the end of a field day the Gahrs returned to the BLM Lander Field Office, where they downloaded the GPS data onto Windows NT computers running Pathfinder Office v.2.51. Differential correction was performed using Trimble Community Base Station data from the University of Wyoming site. The corrected GPS files were edited for known deviant and duplicate data. Data was then exported into an ArcInfo 7.2 format using geographic coordinates in NAD83. During the export Pathfinder Office was asked to include three attributes: rcvr_type, gps_date, and datafile (see attribute section for details) which the software can generate.
