Crime maps

Mock ups for Power of Information Task Force and Home Office

Presume ‘spot’ data available to overlay onto Google Maps – many forces have this, even if they don’t plan to publish it

Aggregates data into ‘post code sectors’ – several hundred households, an approximation to a neighbourhood (eg for NN6 8AH sector is NN6 8)

Includes call to action for people to do something about the crime – unique feature not found on most American and UK crime maps

Overlays non crime data such as schools, pubs, cash machines

All done on presumption that Safer Neighbourhood Teams have limited time

Pictures bring data to life – easy to over estimate numerical literacy when producing league tables and performance data:

47% of the UK population cannot understand…‘straightforward mathematical information’ nor can they ‘independently select relevant information from given numerical information’

‘Skills for Life’ survey 2003 DfES Research Report 490

Is crime rising or falling in my area?

Falling Rising

Computer generated heuristic text based on

data

Where SNT produce info it can be displayed here

SNT police can email in top priorities set by Safer

Neighbourhood Panel and is automatically displayed

Simple vote on SNP priorities

Links to SNT mini site or page on Force website

Slider to set time period for comparison

Post code driven

Force badge is post code sensitive

Two layers of detail and call to action

DUMMY DATA

How can I do something about it…..?

Interactive element – clicking on map converts

to an email to crime reporting email address

Simple email to SNT email address (they all

have one)

Call for volunteers (sends email to SNT)

Basic contact info

Connects to other participation mechanisms to write to Cllr, MP etc via www.writetothem.com and via www.fixmystreeet.com

Call to action almost completely missing in existing mapping propositions

DUMMY DATA

How does my area compare to similar areas?

Computer generated heuristic text based on

data

Crime relative to similar areas – similarity determined from

Acorn Demographic Profiles

DUMMY DATA

What precisely has happened in the last year?

Some crimes could be point data

Simple chart – ultra local, ward, borough

More detailed stats

Computer generated heuristic text based on

data

Detailed selector

DUMMY DATA

Some crimes ‘fuzzied’ up to post code sector to

protect victims etc

Where is it safe to park my car around here?

Car crime in different colours, mapped on to the

location of car parks

Rich potential to blend in other national data sets – eg cash machines, pubs

(for local licensing committees), schools

DUMMY DATA
