In instances where route features do not have from- and to-measure fields populated, you can update them using the LRS Convert Measures To Attributes tool. This tool copies the first m-value and last m-value into fields on the route feature. This allows you to store the starting and ending points for the route features relative to their positions on an entire route. For example, if you have a route that represents a section of Interstate 10, the starting value is not necessarily going to be 0, and the ending value does not represent the end of the freeway.
The m-values can be copied to two fields of type double on the route feature class.
Exporting m-enabled data from the geodatabase to other data formats may remove the measure values in the geometry. Storing the starting and ending measures as attributes on the route ensures that events can still be referenced to the route when using other data formats.
