| Foot mapping is a technique to convey exacting pressure release
information using a coordinate system. Each track should be labeled
whether it is a left or right foot, front or back foot (if
applicable), and the length and width of the foot. Next draw the
track to scale. Very small tracks may need to be scaled up to more
easily identify pressure releases in the track.
Next divide the track into quarters with a horizontal and a
vertical axis. Label the top left Quadrant 1, the top right Quadrant
2, the bottom left Quadrant 3, and the bottom right Quadrant 4.
Now, divide each quadrant with 20 evenly spaced horizontal lines,
numbering them from top to bottom.
Next, divide each quadrant, individually, into 8 evenly space
vertical lines. Letter them from A through H, starting with the line
next to the vertical axis and working towards the outside of the
track.
So, finally, if you were to tell Tom that you have a track of a
man's right foot with a rolling, negative pitched spiralling pock
pressure release covering Quadrant 1, numbers 2, 3, and 4, and
letters F, G, and H, he would know exactly where in the track you
are talking about. Then he would tell you that it indicates that the
person stopped to pick up a coin, or some small object. But, if the
pressure release was found an inch back, it would have meant they
had just bent over. |
