Linear Referencing
Linear Referencing is a way of defining positions along linear geometries
(LineStrings
and MultiLineStrings
).
It is used extensively in linear network systems.
There are numerous possible Linear Referencing Methods which
can be used to define positions along linear geometry.
This package supports two:
- Linear Location - a linear location is a triple
(component index, segment index, segment fraction)
which precisely specifies a point on a linear geometry.
It allows for efficient mapping of the index value to actual coordinate values.
- Length - the natural concept of using the length along
the geometry to specify a position.
