I am experiencing weird off shoots which are beyond my network when creating service areas using Network Analyst. The red circle in the picture below shows an example. I am currently using ArcGIS 10.0 SP5.
ArcGIS 10 Network Analyst Service Area Problem/Peculiarity with Solving, but did not have an answer beyond using detailed polygons instead of generalized polygons.
Where might this error come from?
Perhaps it is due to a dirty/poor network or a peculiarity within the calculation of generalized polygons.
