All the original data were retrieved from http://peterbird.name/oldFTP/PB2002/ in June 2014 and parsed using Python and Global Mapper 11. Further data manipulation was performed in ArcGIS 10.2. The main edits regarded segments spanning the -180/180 boundary, which had to be manually split and moved.
