Maps in support of community oriented policing and problem oriented policing|
Chapter 3: Maps That Speak to the Issues
Three broad categories of maps can be used in support of community oriented policing (COP) and problem oriented
- Crime and offender information. This includes information about the times, locations, and types of offenses, repeated offenses, methods of offenders, property taken, points of entry, linking evidence, types of vehicles used, and suspect information, such as personal appearance and case status, which is also an aspect of accountability (figure 3.16).
- Community and government resources. These include information about neighborhood watch groups, storefront stations (figure 3.17), parolees, probationers, tax assessment and zoning laws, owner occupancy, utility data, patrol beats, building footprints (planimetrics), alarm customers, alley lighting, playgrounds, walls as barriers, afterschool programs, high social stress areas such as low-income housing, liquor stores, and crime
- Demographics. These include information about population change,
ethnicity, race, socioeconomic status (SES), the percentage of female-
headed households with children, the age of housing, and the school-age
Extremely broad-based geoarchives are very useful in COP and POP applications. Because it is impossible to predict what will be needed at any given moment, a reference-type archive is necessary. The ideal, noted in chapter 4, is an "enterprise" database that crosses departmental lines but remains accessible to all agencies.
In addition, there is need for versatility and flexibility in map preparation. For example, line maps of streets will probably need to be superimposed over aerial photos, which demands that their coordinate systems match (for more information, see chapter 4).
