The feature types within the contours enable their representation as individual features to allow for easier interpretation; for example, the contours can be drawn as different colours to highlight the index contours, the high-water mark, and spot heights over a certain value. The contours and tidelines have been rounded to two decimal places.
The column names have been reformatted to facilitate compliance with Esri software.

The ContourLine sub-type value names align with INSPIRE draft elevation specification. The terms 'master' and 'ordinary' represent the more traditionally recognised terms index and standard (contours) respectively.
