Appendix 2. Prospective Mapping SurveyPlease read carefully:The UCL Jill Dando Institute of Crime Science has been commissioned by the Home Office and theGovernment Office for the East Midlands (GOEM) to undertake a research project that has beenpiloted in Derbyshire ‘A’ Division from August 2005 to February 2006. It is essential with a project ofthis kind that an appropriate evaluation is carried out to understand and assess exactly whathappened and to identify any factors that particularly facilitated or impeded implementation.This survey has been designed by the research team to gain an understanding of how much you knowabout the pilot and how useful you feel the maps were in ‘A’ Division, and more specifically, yoursection.Please note that this is an anonymous survey. Your individual answers will not be seen by anyoneother than our research team and we will not be able to identify you by the answers that you give, norwould we wish to do so.Thank you for taking the time to fill out this questionnaire.Please turn over to begin79
