This mapper function returns the standard deviation of each sliding window. The location and elevation returned are those associated with the most recent value in the sliding window.

The standard deviation is the square root of the variance as computed by mapper.var.

The mapper.sd function can only be applied to values of type LONG or DOUBLE, when applied to STRING or BOOLEAN it does not return any value.

mapper.sd is available since version 1.0.11.
