SMS:Recompute All Stations

This function can be used if an arc's "Computational Length" value on a river changes. It sets the Start and End station values for each of the arcs with the same river name based on the computational lengths of each arc. So, for example, if there are three arcs in a river, the most downstream arc being 30 feet, the next arc being 40 feet, and the next arc being 50 feet, the starting and ending stations would be as follows for each of the arcs:

Arc	Start Station	End Station
1 (downstream)	0.0	30.0
2	30.0	70.0
3	70.0	120.0

These start and end stations are set when assigning a river name to an arc, so the Recompute All Stations command should usually not be needed unless there is a change to the computational length, start station, or end station values for a centerline arc.
