Footprint and Tire Track Frame of References


Footprint and Tire Track Frame of Reference:
Two Sided Dual Edge Rulers
 

ORC Forensics’ Footprint and Tire Track Frame of References are rulers and corner squares purposely designed to compliment the FBI’s Bureau Scales.  The original Bureau Scale is a specific corner square based on FBI guidelines and recommendations.  These items are used as official equipment for their photographers at crime scenes.  But don’t worry; we can sell them to you as well.  Use the Footprint and Tire Track Frame of References as measurement guides when taking photographs out in the field, the black-and-white graphics are calculated to give the user clarity and great readability from a distance.

The Two Sided Dual Edge Rulers in this section are made of a hearty 1/16 TK plastic and feature non-glare surfacing.  They each read in millimeter increments on the top and bottom edges, which allow the rules to used in both left- and right-hand reading varieties.  On one side of this Bureau Scale is a white background with black graphics, while the reverse side has a black background with white graduations and numerals.  Two sizes are available in this style, a 15cm long model and an 18cm model.

Another feature of our Footprint and Tire Track Frame of References are the Parralox Circles at each of the ends.  The Parralox Circles are a useful tool to the people who analyze the photographs that have our scales within the frame.  An investigator can examine the shape and displacement of the circle graphics in order to determine if the picture was taken at an angle or if there is a change of depth.  This is something that would be incredibly difficult to ascertain using rulers without these circles.  The Parralox Circles help to prove our commitment to making measuring devices that achieve the highest level of accuracy and functionality.

Dual Edge Fixed Angle Corner Squares

The Dual Edge Fixed Angle Corner Squares share many advantages with our other Footprint and Tire Track Frame of References.  They each possess a non-glare finish on durable .04 TK plastic.  These units are an “L” shape with graduations on each edge of the rule.  The outside edges are 1” (3cm) longer than the equivalent inside edge.  The Fractional versions read in inches with 1/16” graduations, and the Metric styles read in centimeters with millimeter graduations.  The Fixed Angle part of the description refers to the units being made of one piece, stationary at 90º.

Another feature of our Footprint and Tire Track Frame of References are the Parralox Circles at each of the ends.  The Parralox Circles are a useful tool to the people who analyze the photographs that have our scales within the frame.  An investigator can examine the shape and displacement of the circle graphics in order to determine if the picture was taken at an angle or if there is a change of depth.  This is something that would be incredibly difficult to ascertain using rulers without these circles.  The Parralox Circles help to prove our commitment to making measuring devices that achieve the highest level of accuracy and functionality.   

In addition, you will notice that the Dual Edge Fixed Angle Corner Squares make use of our Optirectilinear® graphics.  Notice in the pictures of these Corner Squares the stripe of black-and-white rectangles.  These are the graphics you see on many of our rules and were created to enhance visibility of the rulers’ increments from a distance and in photographs
