Exactly.

Suppose later some one wants to record water flow in terms of volume/time at stations
along a stream passage, where would that go? Or suppose I recorded the temperature at all
of the stations, so I could plot the thermal gradient to help understand airflow? It would
be nice if all this data was contained in one file.

In the discussion of groupings, it is my feeling that it would not be particularily useful
because the groupings typically are not mutally exclusive. I am simply suggesting it would
be easier to examine groupings, associations, relationships after the data is read by the
application. The methods of the groupings are stored as preferences the user has when
using that application, separately. That is like setting file associations in your browser
when you want to open a video clip, e.g. Quicktime vs MSMedia.
