Exam 6: Geographic Data and Crime Mapping

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

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

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

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

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.

Analysts should rely on the default settings of GIS software.

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

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

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

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

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).

The following is not true about mapping by category:

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

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

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

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.

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

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