Google Maps of Australian Crime

At the recent MashUpAustralia event one dataset that generated quite a lot of interest amongst developers was New South Wales Crimes, which allows access to the data by offence type, month and Local Government Area (1995-2008).

All Things Spatial has taken a look at some of the Google Map mashups created with this crime data and has allowed Google Maps Mania to repost some of the highlights.

NSW Crime Explorer

The NSW Crime Explorer presents crime statistics in tables, graphs and on Google Maps as thematic overlays (only 2008 data).

A drop down list of all Local Government Areas enables easy navigation between locations of interest. The Google Map shows 2008 crime data, ranking incidents standardised by population (ABS data) for each NSW Local Government Area (LGA). The map offers a selection of overlays for each crime type and clearly shows where the offences were committed.

NSW Crime Map

This site demonstrates yet another approach to presenting crime statistics with Google Maps and Google Visualisation tools.

The number of crimes committed in major NSW regions, in any given month, is represented as dots on the map. The size of the dots is proportional to the number of committed offences. Different crime types are selectable from a list next to the map and dates can be selected with a slider tool.

A dynamic graph under the map displays monthly counts of incidents between 1995 to 2008.

How Safe Is Your Suburb

How Safe is Your Suburb is an application created with commercial software integrated with Google Maps and Flash graphics.

Crime data is presented in four different ways: based on geographic distribution (thematic map with data table), as a cross tabulation of offence by type and year (pie chart and data table), as a cross tabulation of year of the offence and type by Local Government Area (with line graph and data tables) and as summary statistics highlighting the most dangerous regions in NSW.

NSW Crime

This site provides a very simple mashup presenting crime data in two columns and a Google Map with location points depicting user selected Local Government Areas.

The first data column contains a list of LGAs and counts of all crimes committed in those areas. The second column lists various types of offences and counts for a selected LGA. There is also an option to specify a time range for calculating statistics. Although this is a simple Google Maps mashup it shows a wealth of information.
