Analysis of digital data


Digital Data Analysis is part of De Montfort University FdSc in forensic collision investigation.

There is more and more digital data available to assist in the reconstruction process.  This module firstly looks at what digital data is, its relavence and what to consider before you use it.  The module is not specific to any particular device as there are many different data collecton devices including these days any number of Apps. 

What you will study

  • Block 1 - What is digital Data
    You will be introduced to how analogue waveforms are converted to digital data, the binary number system and data sampling.You will be asked to consider differing sample rates and what the effects may be

  • Block 2 - Telematics
    This block is devoted to the gathering of raw automobile data. It considers in detail what an incident data recorder is, what components make up these devices and what if any variables there are there that cause its reliability to be questioned. The purpose of this is to develop a rationale for the collision investigator when dealing with the question; Is this data reliable? There is no definitive answer and therefore much of the work in this section will be considered by you from your research.

  • Block 3 - Route Tracing
    This block is inextricably linked to both of the preceding blocks especially telematics and will be used to develop further thinking of the overall concept of accuracy and precision. The foundation of thinking for this block will be taken from various research papers and projects where opinions have been formed.

Entry requirements

We assume that you hold a UCPD, City & Guilds or equivalent in forensic road collision investigation. We recommend you have studied Applied maths to get the most from this module.

Pre-course study

Some of the maths will not have been covered at UCPD level but will have been covered in Applied maths. Some of the assessments require the use of a spreadsheets, (Microsoft Excel) thus you will need to be able to use Excel to complete the module. Click on Entry level on the menu bar and select our free Excel course.

Study method

6 weeks distance learning.

What you will need

Your joining instructions list any specific requirements.  General tools include a scientific calculator.  We recommend any Casio with a 'Natural Display'. Microsoft Excel, Apple's Numbers or similar.

Teaching and assessment

Your course tutors will help you with your studies during the course.  They will mark and comment on your final exam and coursework.
