Convention for the positive direction of measurement along a 
linear feature. In DIGGS, measurement always proceeds from 
first to last coordinate, but this allows semantic labeling.
                
These are primarily semantic labels that clarify the meaning of 
"increasing" measurements without changing the fundamental coordinate 
order basis.

Facets
enumeration increasing 
Positive direction follows coordinate order from first to last.
This is the DIGGS standard and default convention.
enumeration downward 
Semantic label indicating positive is downward (deeper). 
Common for boreholes where first coordinate is collar and 
last is bottom of hole. Measurements increase with depth.
enumeration upward 
Semantic label indicating positive is upward (shallower). 
May be used for core logging from bottom to top, or for 
elevation-based referencing systems.
enumeration forward 
Semantic label for horizontal features indicating positive 
is in the forward direction of survey or alignment.
Common for transects, pipelines, and tracklines.
