Crime Scene Sketch

A measured, overhead-view drawing of the scene produced to scale. Unlike a photograph, it records spatial relationships and distances that are free of lens distortion, making it the authoritative spatial record for court and reconstruction.

Common questions
Why is a sketch considered more authoritative for distances than a photograph?+
Camera lenses introduce perspective distortion that makes distances and proportions unreliable to measure directly from an image, while a scaled sketch is built from actual measurements taken at the scene, so it is the record courts and reconstructionists rely on for spatial relationships.
Does a crime scene sketch replace photographs, or work alongside them?+
It works alongside them. Photographs capture visual detail and condition, while the sketch captures accurate measurements and layout, and both are typically presented together in court to give a complete spatial picture.
