What does a Datum Point provide at a crime scene?

A Datum Point provides a permanent, fixed point of reference at a crime scene, which is critical for accurately mapping and documenting the scene. This point serves as a baseline from which all measurements and distances are taken, ensuring that evidence can be precisely located and recorded. Using a Datum Point helps establish a clear and consistent framework for the investigation, enabling investigators to return to the scene or share the information with others involved in the legal process without confusion over the spatial relationships of the scene's elements. Its permanence ensures that the data collected will remain valid and reliable over time, regardless of changes that may occur at the scene. This level of detail and accuracy is essential for maintaining the integrity of the investigation and supporting the subsequent legal proceedings.
