Combining Spatial Analysis Techniques Delivers Powerful Intelligence for Public Safety

Combining multiple spatial analysis methods offers more powerful intelligence for both immediate interventions and long-term strategy. Research from the Rutgers Center on Public Security finds that combining multiple spatial analysis methods offers more powerful intelligence for both immediate interventions and long-term strategy. Hotspot mapping, near repeat analysis, and environmental risk modeling each provide distinct insights:

• Hotspot mapping reveals where crime clusters.
• Near repeat analysis identifies when and how quickly crime incidents are likely to recur near existing events.
• Risk Terrain Modeling (RTM) assesses the environmental characteristics that make places prone to crime.

There's three key findings from the research. First, crime clusters are not just functions of past incidents; they are deeply tied to environmental features like bus stops, schools, and nightlife venues. Second, near repeat events — where new crimes occur close in space and time to prior incidents — are influenced by both past crime and place-based risks. And finally, integrating analytic methods provides a composite risk picture that is more actionable (and predictive) than any single technique.

Therefore, a 3-stage, integrated process for analyzing crime incident location data can produce layered insights for tactical response (prioritize deployments to emergent hot spots), temporal strategy (anticipate windows of elevated risk for repeat incidents), and strategic prevention (focus interventions on high-risk environments before crimes concentrate).

Clear Takeaways

• Crime intelligence is strongest when multiple spatial techniques are combined.
• Analytical integration enhances resource allocation efficiency and supports both tactical and strategic objectives.
• Institutionalizing these processes — within CompStat, SARA problem-solving, or daily operations — is essential for public safety programming that is impactful and effective over time.

Repeating analytic processes that bring together diverse tools and techniques — from hotspot and near repeat analysis to risk terrain modeling — is the best approach to informing operations and driving meaningful action in public safety. Technology platforms like ActionHub by Simsi further support this by enabling analysts and practitioners to operationalize complex spatial insights into clear, actionable strategies that involve multiple agencies and partners who can focus their resources and expertise at key settings.
