Deck 8: How to Perform Spatial Analysis in Arcgis

Question 1

What are two ways of finding a shortest path between stops in a GIS?

Answer 1

Two methods are: 1)Find the shortest path between a set of stops in order.For instance,three stops may need to be visited in a specific order from home-stop 1 first,stop 2 second,and stop 3 third.Of all possible paths,the GIS would determine the shortest route from home to stop 1,then from stop 1 to 2,then from 2 to 3.2)Find the shortest path by re-ordering the stops.For instance,it may be overall shorter to travel from home to stop 3,then to stop 1,then to stop 2.

Question 2

TIGER files typically contain all of the following data except

A)number of houses per street.
B)address ranges on streets.
C)zip code information for streets.
D)names of streets.

Answer 2

A

Question 3

A major road (such as Virginia Beach Blvd. )would be represented in a GIS as

A)a single record.
B)multiple records,with each representing one piece of the road.
C)two records,each representing half of the road's distance.
D)one file entitled "FENAME = 'Virginia Beach Blvd'."

Answer 3

B

Question 16

If an address is matched to the correct street segment but the wrong location on that street,the problem could be that the

A)reference database does not contain the proper zip code information.
B)address ranges in the reference database do not match the actual street address ranges in the real world.
C)linear interpolation algorithm used in the process is out of date.
