Question 1

What is a 'crime hotspot' in geospatial crime analysis?

Accepted Answer

A geographic area with a statistically significant concentration of criminal activity

Answer

A crime hotspot is a specific geographic area where crime concentrates at a rate significantly higher than surrounding areas.

Question 2

Which spatial statistics method is most commonly used to identify statistically significant crime hotspots?

Accepted Answer

Kernel Density Estimation (KDE)

Answer

Kernel Density Estimation smooths point crime data into a continuous surface to highlight areas of high concentration as statistically significant hotspots.

Question 3

In crime mapping, what does 'near repeat victimization' describe?

Accepted Answer

The elevated risk of crime near a location where a crime recently occurred, for a limited time period

Answer

Near repeat victimization theory holds that a crime elevates the risk of new crimes nearby for a short window afterward, often due to the same offender returning.

Question 4

Which of the following coordinate systems is most commonly used in US law enforcement crime mapping?

Accepted Answer

WGS 84 (World Geodetic System 1984)

Answer

WGS 84 is the global standard coordinate system used by GPS and is the most widely adopted system in US law enforcement GIS applications.

Question 5

The 'journey to crime' concept in geographic profiling refers to:

Accepted Answer

The distance and route an offender typically travels from their home base to commit crimes

Answer

Journey to crime research shows that most offenders commit crimes within a limited buffer around their home or anchor point, helping analysts narrow search areas.
