In ARCGIS 10.1 network analysis, why results of service area are different if number of break points is changed?
For example, the grid is 300m*300m, I try to produce service area around a node.
settings are like this...
Then I got this result
then I only change breaks to 300,600, result:
Why the outside border is always in strange shape?
Why the service areas of 600m are different in these 2 cases? I try to change polygon generation to "detailed", it still generate this kind of results.
Really confused, and I have problems understanding any service area result because of this.
Highly appreciated to any ideas!
