6. What else do I need to be aware of when the plot I am mapping is a seabed plot?
There is a section of guidance, Mapping Seabed, that deals with this subject in more detail.
Where a seabed plot is bounded by land, the text in the deed may expressly state that the plot is "bounded by" the foreshore, or that "the boundary between the points A and B on the plan follows the MLWS". There is no requirement to provide OSGB36 coordinates for the landward boundary in these circumstances, provided an acceptable verbal description is contained in the deed. Cadastral units wholly within the SEA registration county will be created using the OPS tool, which does not show the MLWS as a defined feature. Where a seabed plot is described as being bounded by, or following, the MLWS, a request should be made to the GIS team who will add the necessary MLWS data to the OPS tool.
