The Barrow Area Information Database (BAID) road layer includes data for the villages of Barrow and Atqasuk on Alaska's North Slope.
BAID is designed to enhance logistics and research planning efforts. The proximity of research sites and instrumentation to maintained roads is important for project planning, logistics support and maintenance.

For RTK and post processed surveys the precision is greater than .05 m. For locations that were mapped via air photo interpretation +/- 3'
Trimble Survey Controller Version 7.72 precision parameters.
For RTK and post processed surveys the precision is greater than .04 m. This is a function Geoid 99 as applied to the NAD 83 Datum for Northern Alaska.
Trimble Survey Controller Version 7.72 precision parameters.
Road data sources were compiled from Aerometric for areas within the city limits (digitized off aerial photography) and by students from Michigan State University's Arctic Ecology Lab and the University of Texas at El Paso Systems Ecology Lab for the outlying areas using Differential Global Positioning System (DGPS) technology which is post-processed with Trimble Geomatics Office.
