DM-16 - Linear referencing
- Discuss dynamic segmentation as a process for transforming between linear and planar coordinate systems
- Construct a data structure to contain point or linear geometry for database record events that are referenced by their position along a linear feature
- Explain how linear referencing allows attributes to be displayed and analyzed that do not correspond precisely with the underlying segmentation of the network features
- Describe how linear referencing can eliminate unnecessary segmentation of the underlying network features due to attribute value changes over time
- Demonstrate how linear referenced locations are often much more intuitive and easy to find in the real world than geographic coordinates
