Detailed Description

A class to represent a trajectory data set.

This class represents a view on a DataSet that contains observations of a trajectory.

A trajectory represents the variation of spatial locations or boundaries of an object over time. It is composed of an observation data set where one observed property is a geometry. The observations have a fixed object identity and measured geometries at controlled times.
