Keep in mind that OSM apparently uses "compacted" to refer to macadamized roads, which is a specific process for building roads.
Maybe they wiki should be updated to say that roads with loose pieces of gravel scattered around but a hardened underlying surface is compacted, not gravel? -jack -- Typos courtesy of fancy auto spell technology On April 19, 2018 9:22:15 AM EDT, James Umbanhowar <[email protected]> wrote: >I grew up in an area with these kinds of roads and I don't think >they're technically compacted.
