Online Tutorial for Using NACJD Data with GIS Software
NACJD has created an online tutorial to highlight data collections freely available from the archive that can be used for mapping and spatial analysis. This online tutorial consists of four parts:. The purpose was to create a system that could collect case information and link it to specific geographic locations. This study contains the programming code used to customize the user-interface of the Microsoft R Access case tracking database and ArcView R 3. While interest in crime-mapping technology within the law enforcement community appears to be growing, until recently little data existed on how widely computerized crime mapping was used, in what capacity, and which factors influenced an agency's implementation of a geographic information system GIS. Agencies that reported using computerized crime mapping were asked how the spatial analyses were performed and the mapping maintained; what types of analyses were conducted; and which external sources funded, contributed to, and shared the data. Agencies that reported no use of computerized crime mapping were asked whether they used other electronic crime data.
The advent of easy-to-use GIS applications has allowed crime mapping and analysis to flourish within law enforcement agencies. Software, training and resources are easily available to those interest in this use of GIS. The start of the article reviews a crime case in which spatial analysis was used to pinpoint and subsequently arrest a sex offender in Toronto. Most crime analysis produces maps and statistics for crimes that already have occurred. The Los Angeles Times has an article about predictive policing which looks to analyze when and where crimes are the mostly likely to occur. George Mohler, a professor in the Department of Mathematics and Computer Science at Santa Clara University, has adapted math formulas used to calculate aftershocks. Mohler, using the phenomenon that homes in an area that has already been burglarized are more likely to also be burglarized called an exact or near-repeat effect , has developed a computer model to can accurately predict the likely occurrence of crime in a given neighborhood in Los Angeles.
