About this book:

Geospatial Crime Mapping: Using GIS for Patrol Allocation and Hotspot Detection provides a comprehensive guide for law enforcement agencies seeking to leverage Geographic Information Systems (GIS) to transform crime data into actionable intelligence for proactive policing. The book establishes foundational concepts in geospatial crime analysis, tracing the historical evolution from rudimentary pin maps to modern GIS applications, and emphasizes core principles such as the non-random nature of crime, the importance of proximity and context, and the iterative nature of analytical workflows. It meticulously details the critical early stages of data collection, preparation, and geocoding, stressing that accurate location data is the essential bedrock for all subsequent analysis, before progressing to spatial analysis techniques like kernel density estimation (KDE) for visualizing crime intensity and statistical hotspot detection methods including Getis-Ord Gi* and Local Moran's I for identifying statistically significant crime clusters.

Building upon spatial analysis, the book explores the integration of temporal dimensions to understand crime patterns across time, covering diurnal, weekly, and seasonal cycles, time-series analysis, and forecasting methods. It then demonstrates how spatial and temporal analysis converge in advanced techniques such as space-time cubes, emerging hotspot analysis, and risk terrain modeling (RTM) to provide dynamic, predictive insights. Practical implementation is addressed through step-by-step workflows for both QGIS and ArcGIS, encompassing data import, symbology, KDE, statistical hotspot analysis, temporal filtering, animations, and space-time cube creation. The text further applies these analytical capabilities to operational challenges, detailing principles of route optimization for patrol allocation, methodologies for building data-driven patrol zones using GIS, and the application of vehicle routing problem (VRP) algorithms to generate efficient patrol routes, culminating in discussions of dynamic patrol allocation systems that respond to real-time data streams from CAD, AVL, and emerging hotspot detection.

The book concludes by covering predictive policing applications using machine learning and spatial regression models (including spatial lag, spatial error, and geographically weighted regression), rigorous methodologies for evaluating the effectiveness of geospatial interventions through before-after analyses, control groups, and displacement/diffusion assessments, and two illustrative case studies demonstrating measurable reductions in response times and targeted crime reductions. Crucially, it addresses ethical considerations surrounding data privacy, bias mitigation, and community impact, and provides guidance on building sustainable geospatial crime analysis programs through leadership buy-in, skilled personnel, robust data infrastructure, standardized workflows, continuous evaluation, and integration with operational systems. The final chapter looks toward future trends including AI and ML integration, IoT and smart city data, real-time spatial analysis, augmented reality, and the growing importance of algorithmic transparency and ethical governance in shaping the next generation of intelligence-led policing.

What You'll Find Inside:

• Complete workflow of geospatial crime analysis from data collection and preparation through hotspot detection to predictive modeling techniques
• In-depth coverage of spatial analysis methods including Kernel Density Estimation, Getis-Ord Gi*, space-time cube analysis, and Risk Terrain Modeling
• Practical guidance for patrol allocation and route optimization using GIS network analysis tools like Closest Facility, Service Area, and Vehicle Routing Problem solvers

Who's It For:

This book is designed for crime analysts, law enforcement professionals (including patrol officers, supervisors, and command staff), urban planners, and criminal justice students who seek to apply Geographic Information Systems (GIS) to public safety challenges. It will be particularly valuable for those aiming to move beyond reactive policing to data-driven, proactive strategies for hotspot detection, patrol optimization, and crime prediction. Readers should have basic familiarity with crime data concepts, though the book provides foundational knowledge suitable for newcomers to geospatial analysis while offering advanced techniques for experienced practitioners.
