Linear referencing (sometimes referred to as dynamic segmentation) involves storage of geographic data (such as a pipe or road segment) to a relative position along a linear feature (such as a pipeline in a utility network or a road in a road network model) without explicit use of x,y coordinates. Each segment can have unique attribute information.

For linear referencing with the DK, refer to the DK functions:

• ​TGIS_ShapeArc.GetPointOnLine
• TGIS_ShapeArc.GetSegment
