State Highway Network Odometer

The Odometer dataset is used to support accurate distance-based referencing along the State Highway Network. It helps users compare postmile values with actual route mileage, identify mileage changes caused by realignments, and support LRS-based mapping, querying, event placement, and data quality review.
