Amethyst launches new Cornwall Crime Explorer using InstantAtlas: beyond crime mapping to visual reporting

EDINBURGH, UK – 04 April 2009 -- Amethyst, the Information Hub for a Crime and Disorder Reduction Partnership in Cornwall UK, has recently launched their Cornwall Crime Explorer based on InstantAtlas from GeoWise.  The aim of the Cornwall Crime Explorer is to report crime statistics at a local scale to meet the needs of both the local public sector partners and citizens.

The Cornwall Crime Explorer is the result of a collaborative effort between Amethyst and GeoWise to produce a Rich Internet Application (RIA) for crime reporting.  It reflects the years of experience of the Amethyst team in crime mapping combined with the application of sound statistical practices and data visualization principles from business intelligence dashboards.

Data are presented in interactive tables, charts and maps on a single page to assist interpretation.  Commentary taken directly from static reports is embedded in a context-sensitive manner into the application to help people understand what they are looking at.  Detailed background mapping from the Ordnance Survey (OS) provides a rich geographic context to the thematic mapping.  Data are easily updated using Microsoft Excel.

Phil Davies, Project Manager for Amethyst, explains: “We have tried to create an interactive picture of Cornwall that allows users to compare any locality with all others.  We wanted users to be able to understand the levels of crime for different crime types and to appreciate how these levels varied over a much wider area. We are also seeking to communicate how crime levels change over time.  We believe the Cornwall Crime Explorer is a tool that both analysts and casual data users can utilise to support them in an initial ‘scan’ of the crime landscape.”

“Overall” says Davies, “we are very pleased with the presentational capabilities of the Cornwall Crime Explorer and we hope this will lead to greater empowerment through more effective engagement. Amethyst see InstantAtlas as well suited to filling the gap between internal and external crime data reporting.  The lessons learnt from the project are universally applicable to anyone delivering crime data online.”

John Maslen, Government Solutions Director at GeoWise adds: “Development of the Crime Explorer has been a collaborative process.  It demonstrates what can be achieved with limited budget using data visualization tools, built as (RIAs), designed to communicate local statistics.  It contributes good practice in public crime reporting applications for other police forces and public safety agencies. I believe the Crime Explorer demonstrates an evolution from traditional ‘crime mapping’ to effective ‘crime reporting.’”
