Deck 6: Geographic Data and Crime Mapping

Question 1

A GIS uses three types of features to represent objects and locations in the real world-points, lines, and polygons-which are more generally known as:

A)Raster data
B)GIS data
C)Vector data
D)Aerial data

Answer 1

C

Question 2

All but one of the following are steps in the geocoding process:

A)Data entry of crime and address data
B)Preparing the geographic and tabular files
C)Specifying geocoding preferences
D)Matching within the GIS

Answer 2

A

Question 3

A specified area around a feature on a map that can be set at small or larger distances.

A)Polygons
B)Density areas
C)Buffers
D)None of the above

Answer 3

C

Question 4

Geocoding is a seven-step process that is used to bring primary and geographic data together for mapping.

Question 5

Due to the earth being round, there are certain adjustments to the data files as they are incorporated into the software and used for analysis in a GIS to depict geographic data in a flat format.What are these adjustments called?

A)Vectors
B)Coordinate systems
C)Scales
D)Projections

Question 6

Which type of mapping do police agencies use to communicate the locations of drug distribution corners to police personnel?

A)Single-symbol mapping
B)Graduated color mapping
C)Chart mapping
D)Density mapping

Question 7

Graduated mapping can be utilize size or color differences to indicate changes in the data.

Question 8

The following is not true about mapping by category:

A)Categories are typically displayed on a map either as different types of symbols or as symbols in different colors or degrees of shading
B)Variables such as race, sex, method of entry, point of entry, weapon used are most appropriate for these types of maps
C)Single symbol mapping is primarily used in mapping by category
D)Graduated size point mapping is primarily used in mapping by category

Question 9

A type of mapping in which a simplified geographic information system is made available to novice users over the Internet.

A)Web-enabled mapping
B)Internet GIS
C)Customized crime mapping
D)Interactive crime mapping

Question 10

A type of mapping that does not limit does not limit the analyst to examination of predetermined areas, but shows how incidents cluster and concentrate across space.

A)Single-symbol mapping
B)Graduated color mapping
C)Graduated sized mapping
D)Density mapping

Question 11

Which mapping classification is MOST appropriate in mapping robbery locations over the last year to get a sense of the data distribution?

A)Natural Breaks
B)Equal Interval
C)Quantile
D)Standard Deviation

Question 12

A GIS uses four types of vector data to approximate real-world elements: points, lines, areas, and images.

Question 13

Which type or map would a crime analyst use to display incidents of robbery, assault and rape that occurred in a particular area during the same period of time?

A)Buffers
B)Graduated sized map
C)Chart Map
D)Interactive Map

Question 14

A vertical photograph taken from a satellite or an airplane that is digitized and placed within the appropriate coordinates is an example of:

A)Raster data
B)GIS data
C)Vector data
D)Aerial data

Question 15

Two ways of locating tabular data on maps are matching records to parcel data and using latitude and longitude.

Question 16

Which mapping classification is MOST appropriate in determining whether police beats have similar amounts of crime?

A)Natural Breaks
B)Equal Interval
C)Quantile
D)By Category
E)Density

Question 17

Quantile is the only statistical mapping classification used for all three map features.

Question 18

Which mapping classification is MOST appropriate in mapping robbery locations over the last year to get a sense of the data distribution?

A)Density Mapping
B)Equal Interval
C)Quantile
D)Standard Deviation

Question 19

This is a type of mapping in which the sizes of the symbols reflect how many cases were reported.

A)Single-symbol mapping
B)Graduated color mapping
C)Graduated sized mapping
D)Density mapping

Question 20

Which mapping classification is MOST appropriate in determining areas with significantly higher number of auto thefts?

A)Natural Breaks
B)Equal Interval
C)Standard Deviation
D)Custom

Question 21

An inherent problem with density mapping is the fact that it doesn't account for incidents occurring outside of the city boundaries (i.e., border bias).

Question 22

When using either vector or raster data in GIS, it is unnecessary to make adjustments to the data files because GIS depicts geographic data in a round 3D form.

Question 23

In single-symbol maps, individual uniform symbols represent features.

Question 24

In mapping, using different numbers of categories typically yields similar results.

Question 25

Crime analysts take two distinct approaches to the spatial analysis of crime and disorder problems: interactive and graduated mapping.

Question 26

Crime analysts use categorical, statistical, and manual methods in displaying data and statistics in graduated-size and graduated-color maps

Question 27

For categorical and statistical mapping classifications, break points are determined based on the uniqueness of the database being analyzed and are not comparable between different databases.

Question 28

In density mapping, crime analysts use the exact coordinates of incidents to determine concentrations of incidents that are not limited to predetermined areas.

Question 29

The term interactive crime mapping does not refer to a type of mapping; rather, it refers to simplified geographic information systems made available to novice users over the Internet.

Question 30

Analysts should rely on the default settings of GIS software.
