Not sure what you mean. If you split a given country in a higher number of tiles (lower max-nodes) final size will be the same or slightly bigger, as there are more duplicated info due to overlap. Or you are loosing some information in the process to reduce final file size.

    Hi all,

    I wonder what splitter should do in this case:

    Stephen uses paramter --max-nodes=80000
    and splitter reports
    "Highest node count in a single grid element is 557,084"

    It is obvious that at least one tile will have much more than the
    requested 80.000 nodes,
    on the other hand, the file africa.osm.pbf contains large nearly
    empty areas,
    and that makes it very difficult to find a good split.
    The current version r416 fails because it doesn't accept tiles
    with less than 5% of
    the max-nodes value, so it searches for a solution where every
    tile has at least 4000 nodes,
    and that might not exist.

    I see these options:
    1) splitter can continue trying to split the data, accepting
    almost empty output files
    (e.g. some with < 5 nodes and very high aspect ratios like 32)
    2) if that fails,  splitter can set the max-nodes value to 557,084
    and try again
    3) or stop with an error message that tells the user that it is
    not possible
    to split with the used resolution
    4) or restart using a higher resolution  (15 would be required
    here instead of 13),

    @Stephen
    What reason do you have to use such a small max-nodes value?
    Would it be ok for you to use a higher one?

    Gerd
