Name | Type | Definition | Description |
---|---|---|---|
CaveChamber_P | Feature Type | An interconnected series of naturally occurring subterranean chambers. | Typically located in limestone, and often open to the Earth's surface either vertically or horizontally. Alterations may have been made to the cave chamber. |
CaveChamber_S | Feature Type | An interconnected series of naturally occurring subterranean chambers. | Typically located in limestone, and often open to the Earth's surface either vertically or horizontally. Alterations may have been made to the cave chamber. |
CaveMouth_C | Feature Type | The entrance to an interconnected series of naturally occurring subterranean chambers. | Typically located in limestone, and often open to the Earth's surface either vertically or horizontally. Alterations may have been made to the cave mouth. |
CaveMouth_P | Feature Type | The entrance to an interconnected series of naturally occurring subterranean chambers. | Typically located in limestone, and often open to the Earth's surface either vertically or horizontally. Alterations may have been made to the cave mouth. |
Crevice_C | Feature Type | A narrow opening or fissure produced by a crack in the land, especially in rock. | May also describe a deep vertical opening in the terrain that appears after an earthquake. |
Crevice_S | Feature Type | A narrow opening or fissure produced by a crack in the land, especially in rock. | May also describe a deep vertical opening in the terrain that appears after an earthquake. |
Depression_P | Feature Type | A sunken place in the terrain that is completely surrounded by higher terrain. | - |
Depression_S | Feature Type | A sunken place in the terrain that is completely surrounded by higher terrain. | - |
GeologicFault_C | Feature Type | A fracture or zone of fractures in a rock formation, marked by the relative displacement on either side of the plane of the fracture. | The intersection of a geologic fault with the ground surface is termed the 'fault trace' and is commonly plotted on maps to represent a fault. Since geologic faults do not usually consist of a single, clean fracture, the term 'fault zone' (or 'distributed fault') is often used when referring to the zone of complex deformation and numerous small fractures that is associated with the fault plane. |

Hill_P | Feature Type | A small, isolated elevation, smaller than a mountain. | The local relief is typically less than 300 metres. |
Hill_S | Feature Type | A small, isolated elevation, smaller than a mountain. | The local relief is typically less than 300 metres. |
Island_P | Feature Type | A land mass, other than a continent, surrounded by water. | - |
Island_S | Feature Type | A land mass, other than a continent, surrounded by water. | - |
LandArea_S | Feature Type | A geographically defined part of the land. | It may have a proper name (for example: the Alps, the Rocky Mountains or the Great Plains). |
LandMorphologyArea_S | Feature Type | A region of the land surface that is homogeneous with respect to form. | For example: a butte or a valley. |
Moraine_S | Feature Type | An accumulation of soil and stone debris deposited by a glacier. | - |
MountainPass_C | Feature Type | A narrow route through a mountainous region or over a mountain range. | - |
MountainPass_P | Feature Type | A narrow route through a mountainous region or over a mountain range. | - |
MountainPass_S | Feature Type | A narrow route through a mountainous region or over a mountain range. | - |
RidgeLine_C | Feature Type | A line delineating the top of a ridge. | - |
SlopeRegion_C | Feature Type | A region where the terrain slope is within a set range of values. | - |
SlopeRegion_S | Feature Type | A region where the terrain slope is within a set range of values. | - |
SteepTerrainFace_C | Feature Type | A steep, vertical, or overhanging face of rock and/or soil. | For example, an escarpment, a bluff, or a cliff. |
SteepTerrainFace_S | Feature Type | A steep, vertical, or overhanging face of rock and/or soil. | For example, an escarpment, a bluff, or a cliff. |
