The availability of some features of Place-n-Time depends upon the map projection in use.  The following table shows which of these features are available with each projection.

Additionally, the data displayed is only as rich as the data file.  Each of the following features is limited by the available data.  The table below shows what features are commonly available with each map series.  (Technically, each box in the table could be labeled "When available," since there is no guarantee that the data is available for every SDTS transfer.  But my experience has been that the data is usually available for boxes marked "Yes," and usually unavailable for boxes marked "No.")
