HMDIF (Highways Maintenance Data Interchange Format)

UKPMS makes use of a standard file format for the exchange of Highways-related data, known as HMDIF. HMDIF formats have been defined for the following types of data within UKPMS:

• Network Referencing
• Item Inventory
• Condition Data (DVI, CVI, Deflectograph, SCRIM, SCANNER, Rutting)
• Works Records and Pavement Samples
