[Tagging] Geological Faults

[J.J.Iglesias]

Well, is not my goal to map the whole extension of a fault, but just the visible portions like where there is shear terrain indications or waviness in known faults or unstable terrain due to faults, not the actual extension of San Andreas, I agree that there is several Geological Maps were this data is depicted, not in OSM.

  Geological faults should not go into the OSM data base, only visible features should go into OSM. This may include visible features that are caused by geological faults, including, in particular, features that mark such faults on the surface.
  Specialised maps of geological faults exist and can be consulted by experts. Such maps could be meshed with OSM data to produce maps combining surface features and underground features.

    & couldn't this only be done in OSM if the fault (or evidence of it) is actually visible on the Earth's surface?


    I mean, can we actually map a fault that's several / 0's / 00's klm under the ground?


    As David said though, really just a guess as I've also never been involved in that sort of thing.


    Thanks
