026 * A 1-dimensional coordinate system that consists of the points that lie on the single axis described.
027 * The associated coordinate is the distance – with or without offset – from the origin point, specified
028 * through the datum definition, to the point along the axis.
029 *
030 * <div class="note"><b>Example:</b>
031 * usage of the line feature representing a road to describe points on or along that road.
