The key landform=* was created for use with the tag natural=landform to specify the type of landform during the CanVec import. However, most values of landform=* can be represented by much more common tags.
The only other documented tags are landform=dune and landform=dune_system, which duplicate the existing tag natural=dune.
The key natural=* is an established tag for landforms, and natural=* is presently much more commonly used for landforms.
Usage
The key landform=* was added to features with natural=landform, mainly areas mapped as closed ways. There are slightly under 7000 uses of landform=* in this way, as of 9/2019.
Rarely landform=* has used by itself. There are 57 uses without natural=* as of 9/2019
CanVec Import
The tag natural=landform and key landform=* were created for the CanVec import to be used for elements classified as landform in that data set containing various geological forms as well as landcover types. Most of these are generally represented by other tags in OpenStreetMap, therefore you should consider the alternative taggings:
- Eskers (natural=landform + landform=esker) could also be represented by natural=ridge and geological=esker
- Areas of bare undifferentiated glacial debris (natural=landform + landform=glacial_debris) could be tagged natural=esker, natural=till or geological=moraine
- Moraines (natural=landform + landform=moraine) are normally tagged geological=moraine
- Sand areas use natural=sand or natural=dune or natural=beach + surface=sand depending on their form and location.
- Beaches (natural=landform + landform=beach) are tagged natural=beach
- Raised beaches would most appropriately be tagged geological=raised_beach
- Tundra (natural=landform + landform=tundra_polygon) is tagged natural=tundra or natural=fell
- Pingos (natural=landform + landform=pingo) and other permafrost forms currently have no established tagging
