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
GeoSequence
Result Type
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.
