gis substation instrument Prevention in China

The time is right to re-examine current crime prevention policy and consider GIS as a technology that can make a worthwhile contribution to future policy directives. Increasing empirical evidence in the country suggests that crime and geography are inextricably linked which belie attempts to approach crime separately from its spatial context.
