linear referencing / distance-along

A one-dimensional frame defined by distance along a linear feature (road, railway, pipeline). The coordinate is a scalar chainage or mile-marker; conversion to 2D/3D geographic coordinates requires the linear feature's geometry and is performed by the solver layer (Principle 12).
