Question 9

In a service area, the location for which you are determining the area of service is referred to as:

Accepted Answer

B)   rearranging the order of stops
C)   visiting stops in order but allowing the first and last stop to be rearranged
D)   rearranging all but the first and last stops of a network

Question 14

In GIS, a "stop" refers to:

Accepted Answer

B)   An intersection of two lines
C)   A network edge
D)   A network junction

Question 15

How is a service area different from a simple buffer?

Accepted Answer

A)   It can only be created around lines, unlike a regular buffer which can be created around all three vector objects.
B)   It is constrained by the edges of the network unlike a regular buffer.
C)   It can only be constructed in a designated urban setting, unlike a regular buffer that can be created anywhere.
D)   It cannot be created using a distance measurement, unlike a regular buffer.
