Why are some land areas not in land grid cells?

All 25 km grid squares are defined as land or sea, based on whether a majority of their area consists of land or sea. This inevitably means that some coastal locations of the UK are not included with land grid cells.

In detail

Where this occurs, the User Interface will automatically default to the nearest land grid cell that is most appropriate for your selection. It should not be assumed that data for locations that do not have an overlying land grid square is less robust that those that do. It should also not be assumed that locations that do not have an overlying land grid square will be subject to inundation by the sea in the future; sea level projections for points around the UK are provided as part of UKCP09 and these should be used to consider future risks to coastal flooding.
