as also discussed previously, there is slightly different meaning: ground is a synonym for without vegetation/bare (can also be rock) and without man made coating / pavement, earth is about the material (soil, which is organic material and mineral mixed) and dirt could be a reference to dirt roads and mean pebbles or split/grit or sand / dust.

I agree that dirt would better be avoided, as it could mean a lot of things, earth should maybe be soil and instead of ground we should maybe suggest different tags according to what should be tagged.

Substituting earth and dirt with ground should not be done.

cheers,
Martin
