Tools and Tricks for Effective Spatial Analysis Rate Maps

Although "hot spot" maps are very useful in managing crime, rate maps are often more useful for analysis. A rate of vandalism to population may reveal low population areas with high rates. Or a rate of prisoner reentries with drug problems to all reentries will target neighborhoods for specific programs. A density map would not reveal these patterns. Rate maps require several steps, including creation of two density maps and calculation of a rate grid and a "mask" where the rates are not reliable. When population-based rates are used, additional steps are required to reconcile address-based data sources with block-based demographics.

Alternative Tools for Crime Mapping and Analysis

The use of software to aid crime analysis practice and research is essential to handle the mountains of data presented to today’s analysts. The knowledge discovery process includes data manipulation of some sort at each step: Selection, Processing, Transformation, Data Mining, Interpretation, and Presentation. There are many commercial software packages available, but many do not include the ability to customize and tailor the workflow to your organization. This workshop will give the audience the opportunity to learn of free and open source alternative software in the context of crime analysis workflow, and will demonstrate the effectiveness of these tools for each step of the analytical process. The software addressed in the workshop includes: databases, spatial databases, data visualization, data transformation, GIS, web mapping, and publishing. A CD with all software discussed will be included in the workshop materials.

Alternative Tools for Spatial Statistical Analysis

The use of software to aid crime analysis practice and research includes statistical modeling and exploratory data analysis. This workshop will demonstrate several software packages for spatial analysis available to everyone through government and open source software initiatives. Some topics covered will be data manipulation, visualization, and spatial statistical analysis. A CD will be provided with installation media for all software covered in the workshop.

Geographic Profiling De-Mystified

Geographic Profiling –prioritization of suspects based on comparing home and work locations to the distribution of crimes in a series – has become a widely-discussed (and broadly disputed) topic that is a darling of the media. Sensational claims and lively debate among advocates have attracted increasing attention from professionals. But what exactly are these methods, and how do they work? In this comprehensive, hands-on workshop, students will thoroughly explore the ins and outs of geographic profiling, will develop a well-grounded understanding of how these various techniques work “under the hood,” and will learn to perform them all without any specialized software.

Automated Probation Alerts – Spatial Analysis of Contacts

The MPD has built an Automated Email Alert System that, among many useful functions, notifies individual probation officers daily when parolees on their caseload have contact with the MPD. This system ensures timely notice to probation officers throughout Minnesota of the involvement of their probationers in criminal events in Minneapolis, regardless of the probationer’s role in the event. This workshop will inform participants about how the System works, the variety of products generated, and how the spatial analysis of probation contacts was conducted. The results and implications of the study for probation and patrol functions will be discussed.

The Basics of Cartography

The growth of geographic information systems (GIS) in criminal justice has been phenomenal. During the rush to get going with GIS, new users focused on the technology of making maps, ignoring the science and art of making a map. This serious oversight limits the efficiency, effectiveness, and in some instances, the credibility of crime mapping. This workshop is a discussion and illustration of the important basics of cartography. Topics include the elements of a map, generalization and scale, coordinate systems, visualizing different data scales, symbols and visual variables, color design, and different types of thematic maps.

Crime Travel Demand modeling

This workshop presents an overview of crime travel demand modeling, an application of transportation modeling to crime. The crime travel demand model is usually applied to a metropolitan region, though it can be used for other study areas. Attendees will learn about the steps involved and how modeling can be used for policy and intervention analysis. The modeling steps involve a data inventory, trip generation, trip distribution, mode split, and network assignment. Examples will be shown of using a crime travel demand model to study robbery patterns in a metropolitan area and to explore policy interventions for reducing DUI/DWI crashes.

Key Spatial Theories of Crime: What You Need to Know!

Do you want to understand why the dots are where they are on your map? Never had a class in criminal behavior? (or has it been a while?) This session is designed for crime mappers who want a primer on how offenders behave geographically, an understanding that is essential to targeting police and crime prevention activity. Avoiding all of the warm, fuzzy theories that have little practical benefit, this session cuts to the chase and will review the key spatial theories that explain why crime happens when and where it does, including; routine activities, rational choice, and crime pattern theory. The session ends with a brief introduction to the rationale for geographic profiling.

Efficient Animation Workflow Using ESRI Model Builder and Macromedia Flash

Crime analysts and cartographers are forced to find creative solutions to the problem of depicting patterns in time. This workshop will focus on an efficient workflow to create a versatile multimedia product that clearly tells a story and is easily disseminated. The workshop will begin in theory, move to working with ESRI Model Builder, demonstrate exporting from ArcGIS, and then bring the pieces together in Macromedia Flash. This workshop is intended for all audiences, but previous experience with ArcGIS will be beneficial.

Environmental Criminology, Problem Oriented Policing

Crime analysts are increasingly called upon to use their crime mapping and GIS skills to support problem-oriented policing projects. But many new analysts lack knowledge of environmental criminology that would help them to make their full contribution. These concepts include the problem analysis triangle, the journey to crime, repeat victimization, risky facilities, crime facilitators, displacement, and diffusion of benefits. The workshop will show how mapping can use these concepts to support problem-oriented policing projects. It will make use of Crime Analysis for Problem Solvers, a manual published by the COPS Office during the summer of 2005.

Accessing and Using Census Data for Crime Analysis

While many crime analysts are familiar with and extremely capable of analyzing crime data at the point or aggregate level, contextual data is ignored too often when performing analyses. One of the best ways to get a better picture of a crime problem is through the analysis of contextual data about locations to better understand the area and what may be driving an area crime problem. Yet, while contextual analysis is highly beneficial, acquiring and using contextual data is often a long and difficult process, even for the most technologically savvy analyst. This workshop is designed to provide crime analysts with the skills needed to access, download, manipulate, and analyze census data alongside crime data. Specifically, participants will learn how to download census data, create working variables from the data, and use it to perform basic and advanced analysis. Participants will be provided with step-by-step instructions and need not have any prior experience with Microsoft Access, ArcGIS, or SPSS to complete the workshop.

Moving Practitioners beyond Simple Crime Mapping Techniques

This workshop provides participants with a better appreciation and application of descriptive and inferential statistics in comparison to relying exclusively on mapping techniques. The workshop will include five components. First, CMAP's Crime Analysis Tactical Clearing House (CATCH) project will be discussed. CATCH has resulted in the creation of a spatially resolved, standardized database of both solved and unsolved crime series from across the United States. The second component demonstrates the weaknesses of analysis through mapping techniques alone. The second component establishes a foundation of basic descriptive and inferential statistics. The third component focuses on determining which statistical tests are appropriate for specific situations. The fourth component will be a hands-on demonstration of how to conduct specific analysis and interpret the results. Participants will conduct statistical analysis using Microsoft Excel software.

Maximum Mapping: Presentation and Mapping Skills to Get the Message Across!

Many spatial crime analysts spend weeks working on a project only to see their efforts wasted through mediocre maps or poor presentations. This session guides crime mappers and people who might not have taken a cartography or presentation skills class in two ways. The first half explores how people see and interpret color and how this understanding can improve the clarity and impact of maps and graphics. The second half explains how to convey text and graphical information in a Microsoft PowerPoint briefing with some simple guidelines. The presentation finishes up with a concise guide to standing up and presenting!

Spatial Regression Techniques

Spatial regression techniques have been implemented in a number of fields, including criminology, economics, demography, and public health. In this course, we review some of the spatial analytical techniques and their utility in studying social, political, and economic processes. The workshop helps participants develop an intuitive understanding of the utility of spatial analysis techniques in social and policy sciences, a working understanding of using spatial analysis software (specifically Spacestat, GeoDa), and an understanding of the connections between specific spatial statistical techniques and substantive social processes (e.g., operationalizing diffusion processes).

Thematic Mapping Principals

This workshop will address three main themes of the 5 major thematic mapping schemes. First it will address the definitions of each classification scheme. Second, it will address the advantages and disadvantages of each scheme. Finally, it will address ‘when’ and ‘when not to’ use each scheme and which scheme is most/least appropriate based on the underlying data distribution.
