Answer 2

No Answer

Question 3

A geodatabase feature class in ArcGIS can havex,y, andm values:x andy values locate the feature in a coordinate system, andm value is a linear measure.

Answer 3

True

Question 4

What kinds of data are required as inputs to address geocoding?

Question 5

Geocoding errors are typically higher in rural areas than urban areas.

Question 6

Which of the following can be used as reference data for geocoding in the United States?

A) SDTS files
B) DLG files
C) TIGER/Line files
D) SSURGO files

Question 7

Dynamic segmentation bridges two measure systems. What are these two systems?

Question 8

How can you tell a point event table from a line event table?

Question 9

What is intersection geocoding?

Question 10

You are asked to prepare an event table that shows portions of I-5 in California crossing earthquake-prone zones (polygon features). You are given two digital maps of California, one showing the interstate highways and the other showing earthquake-prone zones. Describe the procedure you will follow to complete the task using dynamic segmentation.

Question 11

Errors in address geocoding can be caused by:

A) both misspelling of street names and missing zip codes
B) missing ZIP codes
C) outdated reference database
D) all of these are correct
E) misspelling of street names

Question 12

A geocoding engine uses ________ to determine whether an address is matched or not:

A) minimum candidate score
B) Both of these are correct
C) minimum match score

Question 13

What methods can one use for creating routes from existing linear features?

Question 14

Illustrate the use of linear interpolation for address geocoding.

Question 15

Define "geocoding."

Question 16

How can photos be geocoded?

Question 17

Geocoding is used by Internet browsers such as Google and Yahoo for location-based services.

Question 18

Different events can reference the same route.

Question 19

Explain the importance of geocoding in crime mapping and analysis.

Question 20

Explain how linear measures are stored in a route feature class of a geodatabase.

Question 21

Bus stops are treated as _____ events along a bus route:

A) continuous
B) linear
C) point

Question 22

A route intersects itself is called a:

A) combined route
B) looping route
C) split route
D) simple route

Question 23

Define "routes" and "events" in dynamic segmentation.

Question 24

You are asked to use the dynamic segmentation method to verify the statement that traffic accidents happen more frequently along stretches of a highway with poor pavement conditions. What types of data will you need for the project? What procedure will you follow to analyze the data?

Question 25

Different routes can be built on the same linear features.

Question 26

Street-level geocoding refers to:

A) address geocoding
B) intersection geocoding
C) Both address geocoding and intersection geocoding
D) ZIP code geocoding
E) All of these are correct

Question 27

Geocoding can be based on:

A) Place names
B) All of these are correct
C) Street address
D) Both street address and place names
E) Parcels

Question 28

One can use a reference database that is based on geographic coordinates, instead of projected coordinates, for address geocoding.

Question 29

Point and polygon layers can be used as inputs for creating event tables in ArcGIS.

Question 30

Event tables can be created from an Excel table as long as the Excel table includes the route ID and linear measures.
