This procedure enhances attribute accuracy by reducing attribute related decision-making in the field and minimizing keying errors. Park staff have ground checked and verified all features to the best of their knowledge. GIS personnel verified all features and attributes. Logical_Consistency_Report: There are no duplicate features present. Polygon features (if present) begin and end at the same point. . Completeness_Report: The data only includes features shown to the GPS collection team by a park staff member while on site. Additional features may exist at Fort Laramie NHS. 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 (satellite vehicles). These data were differentially corrected and have estimated accuracies in the X and Y direction of 0 to 5 meters, using the above standards while SA (selective availability) is set to zero. No tests were done to confirm this. In Trimble Pathfinder Office software, accuracy is not represented. Instead, precision is an estimation of the positional error (closeness to truth) available as feature attributes. To estimate precisions the software uses: receiver type (for noise), baseline length, Dilution of Precision, covariance and reference variance components. It is a repeatability measure not an accuracy measure. Horizontal Precision for line and area features looks at all the individual points that make up the line/area feature and a mean value is computed by the software.

Process_Step: Process_Description: The transportation theme was included as road and trail features in the data dictionary attribute menu for use in the GPS data logger. GPS based coordinates were collected at Fort Laramie NHS during June of 2002 using Trimble ProXR and GeoExplorer3 receivers in datum NAD83, UTM - zone 13, meters coordinates. A maximum Position Dilution of Precision (PDOP) of 6 was maintained for each set while tracking a minimum of 4 satellite vehicles. Source_Used_Citation_Abbreviation: GPS data Process_Date: Process_Step: Process_Description: The GPS processing software was Trimble Pathfinder Office Version 2.51. GPS files were differentially corrected using Trimble Community Base Station data from the University of Wyoming site. The corrected GPS files were edited for known deviant and duplicate data. The Pathfinder Office Combine utility was used to merge features collected with identical data dictionaries by different GPS collection teams throughout the 2 day collection period. The combined features were then exported into ESRI ArcView version 3.2 shapefile format. Source_Used_Citation_Abbreviation: GPS data Process_Date: Source_Produced_Citation_Abbreviation: GPS data Process_Step: Process_Description: Feature data was compared to features in the digital raster graph and digital orthophoto quarter quads for accuracy. GIS personnel verified all features and attributes.

The next 2 items, TYPE & COMMENTS were user-defined attributes from the GPS's datalogger data dictionary user input. The last item, MARKINGS, was created while in ArcView to add additional field note information. The remaining items had Pathfinder software produced values: PDOP_MAX, CORR_TYPE, RCVR_TYPE, GPS_DATE, GPS_TIME, DATAFILE, UNFILT_POS, FILT_POS, UPDATE_STA, STD_DEV, GPS_HEIGHT, HORZ_PREC, VERT_PREC.
