Individual Landscape Features
These maps show the individual landscape features plotted from 2D and
3D data. For further detail refer to the maps in the popular booklet and in the technical
Note that the features shown in the Bristol Channel area are extrapolated
from 2D data, and thus although their general character and location is likely to be correct,
no detail is known; implying that there are numerous landscape features awaiting discovery
in this area. Features identified from the 2D data include two lakes/areas of wetland, numerous
channels and areas of higher ground.
In Liverpool Bay the area for which high quality 3D data is available is
clearly delineated by the large number of individual landscape features identified. These
mainly consist of fluvio-glacial and other channels cut into a wide, low-lying plain. The
absence of these features immediately to the south and east is not a true absence, but rather
indicates a lack of 3D data. Here, many more similar landscape features may await discovery.
Closer to the Welsh and English coasts the situation is similar to that of the Bristol Channel,
where features were extrapolated from the only available 2D data.
