The first site appears relatively new and approaches what I see as second generation crime mapping. To put it simply first generation by my definition maps the location and times of crimes to a varying degree of accuracy and comprehensiveness. Second generation crime maps should focus much more on police activity tackling the policing problems within neighbourhoods with the purpose of addressing communication, reassurance, crime prevention, confidence, performance and funding issues. Second generation crime maps are therefore "Policing Maps" for the public.
I give Myneighbourhoodupdate.net a big thumbs up because it uses police incident data to map police activity.
