landformdescriptionvalue

This code list is used in association with the Description attribute which is present within the Landform Feature Type. The code list describes the types of landform features represented as polygons, such as a cliff, an artificial slope for transport, or a burial mound.

Label	Definition
Area Of Disused Shafts	An area of multiple collapsed, partially filled in, or covered, vertical (or near vertical) shaft entrances related to former mining activity.
Area Of Former Mineral Workings	An area of land with a collection of different features indicating former mining activity. This is for areas where there is clear evidence from the terrain of mining activity, but the features cannot be precisely captured and identified because of their age. Examples include areas of former tin or lead mining where a mix of disused shafts, hushes (channels washed out to expose minerals), dams, drifts, levels, spoil heaps and other unidentifiable features combine to form a distinctive landscape, but most or all of the individual features appear too eroded to be captured individually.
Area Of Shake Holes	An area of steep-sided holes or funnel-shaped depressions in the ground, formed as the result of subsidence over underground cavities.
Artificial Slope For Flood Controlling	A manmade inclination in the ground designed to manage the level of water during abnormal conditions. Applies to flood prevention banks, typically located alongside rivers.
Artificial Slope For Flood Or Water Controlling	A manmade inclination in the ground designed to manage the level of water during both normal and abnormal conditions, or when the more specific function cannot be determined.
Artificial Slope For Historic Purpose	A manmade inclination in the ground which is the result of historic activity.
Artificial Slope For Mineral Or Fuel Extraction	A manmade inclination in the ground associated with mineral or fuel extraction.
Artificial Slope For Other Built Environment	A manmade inclination in the ground associated with the built environment and not included in any other slope function classification. This is usually used where major earthworks have been undertaken to allow the construction of buildings or playing fields or similar.
Artificial Slope For Screening	A manmade inclination in the ground designed to reduce the visual or audible impact of another feature. This also includes containing any spillage from hazardous substances, or impacts from explosives.
Artificial Slope For Transport	A manmade inclination in the ground associated with transport infrastructure.
Artificial Slope For Unknown Purpose	A manmade inclination in the ground, where the purpose of the slope has not been identified.
Artificial Slope For Water Controlling	A manmade inclination in the ground associated with a body of water, such as a dam or reservoir, and rivers and canals. Includes banks for dams, and balancing ponds.
Bell Pit	An underground structure, like a small cave, accessed by a vertical shaft, generally used for mineral extraction.
Boil Hole	A hole in the bed of a watercourse where water emerges under pressure into the watercourse.
Burial Mound	An ancient burial mound, being of historical interest.
Cave	A subterranean chamber, usually natural, with an entrance from the surface.
Cliff	The feature representing a steep rock face, usually natural, most commonly occurring where the land meets the sea. Cliffs may be semi-natural, in the case of disused mineral workings, or manmade, in the case of rock faces that are the result of construction activity.
Coastal Slope	An area of steep natural slopes along the coast. They are less steep than a cliff; however, because of their nature, they are rarely put to any use, and are commonly covered in some form of vegetation. They may appear similar to cliffs, but made are of earth rather than rock.
Collapsed Shaft	A collapsed or partially filled-in shaft.
Dene-hole	An underground structure, like a small cave, accessed by a vertical shaft, generally used for mineral extraction. Specific to chalk areas of the South East of England.
Grotto	A cavern, usually artificial, that contains attractively shaped or coloured rocks, and is commonly part of formal gardens.
Historic Cave	A subterranean chamber, usually natural, with an entrance from the surface, that is of historical interest.
Historic Pot Hole	A natural hole caused by the erosion of underlying limestone, and being of historical interest.
Level	A horizontal or near-horizontal area from which mining is undertaken, typically the entrance to an Adit.
Mound Of Earth As Boundary Marker	A low hill, either natural or artificial, indicating the proximity of an administrative boundary alignment.
Pot Hole	A natural hole caused by the erosion of underlying limestone.
Ravine Slope	A steep-sided natural slope, forming ravines / gullies which, in turn, form an obstruction to pedestrians in an area which is generally traversable by pedestrians.
Sand Dune	Small ridges or hills of sand found at the top of a beach above the inter-tidal zone, usually with patches of rough grass that stabilise their position.
Shake Hole	A steep-sided hole or funnel-shaped depression in the ground, formed as the result of subsidence over underground cavities.
Swallow Hole	A hole into which a stream empties, usually in limestone areas.
