<dd><p>Provide a hint to the Data Access Framework indicating whether to load the
lat/lon data for a grid immediately or wait until it is needed. This is
provided as a performance tuning hint and should not affect the way the
Data Access Framework is used. Depending on the internal implementation of
the Data Access Framework this hint might be ignored. Examples of when this
should be set to True are when the lat/lon information is not used or when
it is used only if certain conditions within the data are met. It could be
set to False if it is guaranteed that all lat/lon information is needed and
it would be better to get any performance overhead for generating the
lat/lon data out of the way during the initial request.</p>
