2-Day Shooting Scene Documentation Course


Course Objectives: The goal of the course is for attendees to understand what shooting documentation methods are best to choose in any one situation and what methods are easily deployed or at their disposal. Various methods including the laser scanner and digital camera with basic tools will be covered. There are other techniques that include digital ellipse fitting and “virtual scans” which will be demonstrated. Attendees will walk away from the course with some extra tools to assist with good trajectory documentation.


  • Manual measurements with angle finder and protractor

  • Photographic measurements with Photoshop or Gimp (free)

  • Photographing glass and converting to “virtual scan”

  • Ellipse method with CloudCompare

  • Rocker method/Lead-in method

  • Cartridge Case ejection patterns (documenting at scenes)

  • Shotgun blast patterns – documenting, calculating area and distance.

  • ...and more

Part of this course is to understand the literature and latest research surrounding uncertainty, errors and how different methods may be better applied than others. Hands-on applications of these methods with some simple tools plus working with digital software will be part of the course.
