What does the coordinate method involve?

The coordinate method in crash investigation involves taking two measurements from a reference point to accurately locate evidence and points of interest on an accident scene. This method is crucial because it allows investigators to create a precise mapping of the area, ensuring that all relevant details can be documented and later analyzed. By establishing a reference point and measuring distances in two perpendicular directions—typically horizontal and vertical—investigators can accurately reproduce the scene for further examination, court presentation, or reconstruction purposes. This method enhances the reliability of the data collected, which is fundamental in understanding the dynamics of the crash.
