About calibrating route measures using points—ArcMap

Calibration. It is possible to adjust route measures to correspond with known measure locations using a procedure called calibration. Calibration adjusts route measures by reading measure information stored as an attribute in a point feature class. Each point falls on the particular route it calibrates or within a given tolerance of the route line.Get price
