AS a crime analyst you need to establish a few maps that would help police to do targeted patrols, I've given data of suburbs, roads, incidents, boundaries. How can I establish patterns, hotspots and clusters?
The best applied application for performing hotspot and cluster analysis is CrimeStat. You will find all the needed data here:. Download it and use the manual to see what you can perform there.
Basically you will need a shapefile with the locations of the crimes, which you load in the first tab:
after which you will have access to the other tabs where you set up the analysis parameters, and use the Save... buttons to generate the files with the results.
I do not know what you mean by patterns, but CrimeStat also have a module for Spatial Modelling and Crime travel demand, so please read the docs and the papers behind the software and see if they match your needs.
