Returns the approximate speed at a specified point (SpeedN(index INTEGER)) or between two points (SpeedN(iBegin INTEGER, iEnd INTEGER)) for a GeoSequence type.
Valid Data Types
Returns a FLOAT value.
|IF you pass in …||THEN …|
|iBegin and iEnd||the speed is calculated as the distance between the two points (along the LineString) divided by the time between them.|
|index||if the point is:
The units used for distance are the same units that are used by the coordinate system for the GeoSequence value, and the time units are in hours.
