5. Conclusion
In this paper, GIS-based hot spot identification in criminal cases, mainly for the testing spatial patterns
of criminal cases, criminal cases and case studies focus calculation. Spatial patterns of criminal cases
developed test tools, point form of hot computational tools, surface area calculation tool and oval shape
hot hot form computational tools. Finally, the Chinese city in 2010, drug cases, identify hot spots of
criminal cases were demonstrated. Through case studies concluded that: the process of identifying hot
spots of criminal cases, in criminal cases, the distribution of spatial patterns are clustered under the
premise of different forms according to the characteristics of hot spots of criminal cases should be
followed by complete surface area calculated form of hot, hot point calculations and forms Hot oval shape
calculation. Hot spots in the clear area on the basis of surface morphology can be a particular hot spot
area for further calculation of points and elliptical shape hot hot form calculated to get more accurate
information on hot spots of criminal cases.
