What is meaning of breaks in Service Area Layer (Network Analyst)?

[AragonNette]

hi i am working with Network analysis in ArcGIS rest api and i didnt understand what the meaning of Default Breaks in rest structure ..

when i write 1000 in this input field it was giving me big polygon from 500...

is it meaning of  1000 meter or 10 minutes from added point?

thank you

"Default impedance values indicating the extent of the service area to be calculated. The default can be overridden by specifying the breaks value on the facilities.

Multiple polygon breaks can be set to create concentric service areas. For instance, to find 2-, 3-, and 5-minute service areas for the same facility, specify "2 3 5" as the value for the Default break values parameter (the numbers 2, 3, and 5 should be separated by a space)."

Make Service Area Layer

thnk for your reply

but in rest api 5 minutes not meet real result. when i add polygon of service area on my map it is drawing so little area... to accomplish this i multiplication 5 minutes with 100 for getting correct result...

my breaks_length : 10
polygon distance :100
outsr : 3857

is it to be involved with upper stettings?

Hi Aragon,

Could you tell what network dataset are you using?
What is the value of the impedanceAttributeName parameter you specify?

thanks,
Dmitry
