| This map shows our test GPS data taken on a drive in Seattle, WA USA and its eastern suburbs. The trip starts in the upper right corner near Marymoor Park. The data was sampled at 1 Hz using a RoyalTek RBT-2300 GPS logger. The drive took place on Saturday, January 17, 2009 starting at 20:27:37 UTC (12:27:37 local time) and ending at 22:34:28 UTC (14:34:28 local time), for an elapsed time of 02:06:51. A much higher resolution map is available here. |

Note that it is always permissible to travel from the "From Node" to the "To Node" on an edge. If "Two Way" is 1, then it is also permissible to travel the opposite direction.
