Manage and deliver IMKL network data

The information model cables and pipes (IMKL) is a Dutch standard data model for the data exchange of digging activities. The IMKL is founded on the INSPIRE models for cables and pipes. The IMKL is the result of a Dutch law concerning the information exchange for underground networks (WION). The purpose of the WION is to prevent economic losses caused by digging damage to water and gas pipes or electricity and telecommunication cables.

Diggers are obligated to report their digging activities by the Kadaster. The Kadaster is the Dutch authority that manages the national registration of cables and pipes. The network administrators are obligated to offer their network information in a digital format to the Kadaster. Network administrators deliver their network information to the Kadaster in a GML format according to the IMKL standard. The data model of the IMKL standard is fully described in a XSD used by the Kadaster to validate the delivered network information of the administrators.

Network information concerning pipes and cables is usually available by the network administrator in other formats (ESRI Shape file or AutoCAD) than the IMKL format. Existing network information can be imported and further managed in GeolinQ. The IMKL model is generated in GeolinQ based on the XSD describing the IMKL model. The existing network information of the administrator is bind by views and unions to the generated IMKL model. The network information is exported as GML based on the IMKL XSD and finally delivered to the Kadaster.
