Trackway	Combination of impressions, imprints or trails displayed in a recognizable manner across the substrate.
Midline	Theoretical line parallel to the long axis of the trackway and located halfway between the external margins.
Medial	Referring to imprints positioned anywhere between the greatest lateral extent of the trackway.
Stride	Distance between two adjacent tracks on the same side of and measured parallel to the medial line. Note again that tracks occur at standard intervals.
Width	Distance between outer edges of tracks measured across the midline.
