### Standardized water level exchange format

The IEHG has agreed upon a standardized data exchange format for detailed water level information that can be used by applications to display the actual water depth or for voyage planning. A precondition is the encoding of the depth in accordance with I.1.2 of the Encoding Guide for Inland ENCs:
