Up-to-date and accurate maps of the waterways are a prerequisite for safe and efficient shipping in Germany. Authorities such as the Federal Maritime and Hydrographic Agency, but also private harbour operators, are obliged to provide these in an up-to-date form at all times.
The main reason for this is to avoid accidents caused by an incorrect or outdated card. This includes the classification of federal waterways, their kilometres, existing locks, lifting and barrages, other surrounding waters, places and borders. Currently, mapping is carried out by conventional ships with trained personnel, which is time-consuming and expensive. This can result in long intervals between measurements at a particular location.
