Triangulation Method - Answer-From two fixed points, measurements are taken to
specified points on an item or within the crime scene. There is no need to worry about
whether or not measurements have been made at a right angle because the points
derive from a known fixed point, such as the corner of a room, or edge of a door frame.
From these fixed points, a minimum of two measurements are made to each identified
point
Rectangular Coordinate Method - Answer-Two measurements are taken to a point on
an item or location at the scene. One from each identified baseline.
Base Line Method - Answer-This is the most basic—and least accurate—form of crime
scene mapping. For this method, a baseline is developed or identified from which to
conduct measurements. This can be an existing area, such as the edge of a roadway, a
wall, fence, etc., or it can be developed by personnel, such as by placing a string or
tape measure through the scene and conducting measurements from there.
Once the baseline is established, measurements are taken from the baseline at an
approximate 90 degree angle from the baseline to a point on the identified item or area
of the crime scene
