Calculating LRS Measure Values For Crossings

How can I calculate LRS Measure (KM or mile marker) values for where linear data such as rivers etc cross my road network?



The following GeoMedia Transportation workflow might be used as a means to calculate LRS measure values where another linear feature crosses LRS network.



In the attached workflow document, the following steps will be used to calculate LRS measure values on intersection markers for where rivers overlap the LRS network:

  • Review Coordinate System of the LRS
  • Perform spatial intersection of LRS with the crossing linear feature class (rivers in the example workflow)
  • Use functional attributes to:
    • expand collections
    • filter for true point geometries
    • calculate X and Y projected coordinate values
  • Use GeoMedia Transportation Conversion to convert the coordinate values/events to LRS measure values
