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.

  • I get these issues is my services areas sometimes too and would like to know why it is happening. – bailey Dec 6 '17 at 17:01
