Existing data from the water board is verified, validated and, where necessary, supplemented. The digital register is loaded with objects and is, of course, subject to change. To update this register, the unique Iv-Infra scan car was deployed to accurately map the non-flood defence objects. The additional data collected by the scan car allows objects to be approved quickly, for example; it can be demonstrated that the dimensions of an object are so minute that any occurrence of failure will not influence water safety. The testing of all non-flood defence objects is thus improved and made more efficient.
