Surviving circles should be examined further for possible related variables or at the very least mapped because they cannot 18 I. Turton and S. Openshaw so easily be made to go away. However, there may also be a case for looking at the circles that GAM found signiﬁcant but which in whole or in part have been explained away to try and establish the reasons and the coverages responsible. Mode 3: GAM as a ‘GCEM’ Another way of running GAM is to change the mode 2 operation so that it replicates the intention inherent in the original ‘GCEM’ (the Geographical Correlates Exploration Machine outlined in Openshaw et al.
Indeed, there are many different possible variables that may be considered important. Some of these could well be related more to individual behaviour, others to geographical location, and some to both. This is particularly the case in studies of disease, where some important variables relate to the unmeasured individual exposure to allegedly harmful chemicals. Yet many of these ‘thought to be important’ variables in developing a better understanding of a disease may well be missing from the available spatial databases.
Part Four contains two North American contributions, which give an international perspective on crime mapping. The US is particularly advanced in the use of crime mapping and spatial analysis tools for informing crime prevention practitioners. Doug Williamson and colleagues describe a software package developed for use by the New York Police Department (NYPD) that offers a number of spatial analysis and mapping techniques that can help inform the Police of emerging crime problems. The techniques described include block aggregation, voronoi diagrams, kernel smoothing and animation.
