Description:
Abstract:
This coverage, created by the Alaska Department of Transportation and Public Facilities Statewide GIS Mapping Section, depicts the roadway centerlines for the major highways in Alaska . The centerline data was collected using a Trimble Pro XR DGPS receiver during the summer of 1997 to the fall of 1999. The raw centerline data was exported from Trimble's Pathfinder Office software into ARC/INFO where it was converted into an arc coverage, edited, attributed, and projected.
Purpose:
The Alaska Department of Transportation and Public Facilities Statewide GIS Mapping Section collected the DGPS centerline data and created this centerline coverage in an effort to establish a current, accurate digitial transportation data set for the state.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The road centerline data was collected using a twelve channel Trimble Pro XR receiver with a Trimble TSC1 data logger running Trimble's Asset Surveyor software. Centerlines were captured as line features with a collection interval of one position per second. All rover files were differentially corrected with the best available base station data.

Trimble specifies the Pro XR receiver as capable of delivering differentially corrected C/A code position accuracy to better than 50 centimeters (RMS) horizontal. The 50 centimeter level of horizontal accuracy is obtained only under optimal operating circumstances. The accuracy of each determined position may be greatly degraded by many factors. Factors that degrade accuracy may include but are not limited to atmospheric interference, satellite geometry, satellite clock errors, satellite orbit errors, topography, receiver noise, and multipathing errors.

Since our road centerline data was collected in very dynamic driving conditions it is not possible to make a blanket statement of accuracy. However, Trimble's Pathfinder Office software does provide tools to predict the precision of both individual observations and entire features. Trimble's precision estimates are RMS based. Average horizontal 2dRMS values for our road centerline data range from four to eight feet. Precision estimates should be used as a gauge of quality and repeatability and not be misconstrued as a measurement to or from true feature location.
