Handling of line pause during collection with GPS input on SIR-4000 about readgssi HOT 4 CLOSED

a GPS velocity record pulled from the DZG of a line with a big pause in the middle (y axis unit is meters per second):

from readgssi.

Pause identified by velocity falling below a threshold (0.16) for more than 3 samples:

from readgssi.

A more surefire way: find values under a velocity threshold, group them together based on their contiguousness and cut them into categories, then test whether the number of consecutive rows is greater than 3:

This means the algorithm ignores brief speed drops:
