Which of the following is listed as an advanced measurement method for sketches?

• A. Triangulation
• B. Laser systems
• C. Compass rose
• D. Transecting baseline

Answer: (B)

Laser systems are an advanced measurement method for sketches because they provide direct, high-precision distance data and create detailed 3D representations of a scene without physical contact. In forensic documentation, this means you can quickly capture accurate coordinates of objects and surfaces, generate point clouds or 3D models, and export data to CAD or analysis software. This reduces human error from manual measurements and calculations and speeds up the process, especially in complex or large areas where traditional methods might be slow or incomplete. By contrast, triangulation relies on angular measurements and known baselines, which require more manual setup and calculations; a compass rose is simply an orientation symbol on a drawing, not a measurement method; and transecting baseline involves establishing and moving along a baseline to collect measurements, which is still manual and time-consuming.
