A data frame is a set of data columns along with some associated metadata including:
the latitude, longitude, elevation, and time zone
the type, units, color, and measurement height of each data column
the column display settings that determine the naming, order, and visibility of data columns
the list of flagged segments, flags and flag rules used in the data frame
some default calculation settings including shear profile, calm threshold and Weibull fit algorithm
You can think of a data frame as a table of data displayed in rows and columns, with a row for each
time step and a column for each
data column like the following example:
Start Time
Speed 75m
Direction 72m
(m/s)
(°)

A dataset contains the current data frame plus a list of
revisions, some of which may contain archived data frames.
