| 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.  |
