  We present a data simulation package designed to create a series of simulated
data samples for a detector with non-destructive sampling capability. The
original intent of this software was to provide a method for generating
simulated images for the Next Generation Space Telescope, but it is general
enough to apply to almost any non-destructive detector or instrument.
MultiDataSim can be used to generate "practice" sampling strategies for an
instrument or field-of-view, and thus can be used to identify optimal
observation strategies.
