Tracktype is a measure of how well-maintained a track or other minor road is, particularly regarding surface firmness. It usually applies to highway=track but is often used for non-tracks too, especially in less-developed places where many main roads are unpaved. The proposal from which this key originates may be found at Proposed features/grade1-5. The proposal was voted on, but was standardised primarily because of its widespread use.
surface=* refers to surface material and sometimes to material structure. It may suggest a track type sometimes, but because the same surface material/structure can exhibit various degrees of firmness, it is still advisable to add tracktype=*.
smoothness=* is also an important surface property and refers to surface regularity/flatness, regardless of material.
See below for tag values for 'tracktype':
|tracktype||grade1||Solid. Usually a paved or heavily compacted hardcore surface.|
|tracktype||grade2||Mostly solid. Usually an unpaved track with surface of gravel mixed with a varying amount of sand, silt, and clay. See Gravel road on Wikipedia.|
|tracktype||grade3||Even mixture of hard and soft materials. Almost always an unpaved track.|
|tracktype||grade4||Mostly soft. Almost always an unpaved track prominently with soil/sand/grass, but with some hard materials, or compressed materials mixed in.|
|tracktype||grade5||Soft. Almost always an unpaved track lacking hard materials, uncompacted, subtle on the landscape, with surface of soil/sand/grass.|
