SpeedN ( { index | iBegin, iEnd } )
- index
- An INTEGER for the index of the point within the GeoSequence type, where the index of the first point is 1.
- iBegin
- An INTEGER for the index of the starting point for which to calculate the speed, where the index of the first point in a GeoSequence type is 1.
- iEnd
- An INTEGER for the index of the ending point for which to calculate the speed, where the index of the first point in a GeoSequence is 1.
