Iowa is one of the few states with a full Linear referencing System (LRS) on all public roads and statewide LiDAR. Iowa’s LRS gives the ability to locate with many methods, like mile point, and translate from one method to another. The LRS also stores accurate traveled way centerlines of over 114,000 miles of public road.
