    At present the names for larger islands do not show on the maps. As far as I can see this is because larger islands are multipolygon relations. Would it make sense to treat them in the same way as (for example) desert, forest, wood, orchard, glacier, mountain_range, mountain_area etc.?

    Hi John,

    The reason why place labels tagged as within areas/ways/multypolys are not shown on the map is that „places“ are only included as NODES in the tagmapping. So only dedicated nodes „place=island“ is shown on the map.

    For me its perfect easy to handle the islands in the same way as other poly-labels = place labels in the middle of the island and add a bboxweight tag so that the labels of the bigger islands are shown at low zoom rates , labels from smaller islands at (eg) level 15.

    However, there will be duplicate labels with islands where a single node + a place as tag within MP.
    See on the shetlands: Noss, Mousa, St.Ninians, …
    It would be possible to remove the single nodes in tagtransform prior to making poly_labels so only place=island drived from MPs are shown on map.

    Themes would have to be modified to render island labels according to size of the polygon (bboxweight)

    @John,@Tobias – what your opinion on this.

    Best regards
    Christian

    That seems a good idea to me.
    PS The forum seems to have a mind of its own at present. I posted „seems“ above and it showed as „means“. I’ve corrected that but it now changes my British quotes to German ones.

    Fine for me. I’m not sure if bboxweight is really needed, this needs testing.
    Removing nodes for place=island is maybe not a good idea, as there are possibly islands that don’t have place=island on the ways.
    While you’re at it, place=islet and place=archipelago should have the same treatment then. Other places hopefully still have the node as main tag, although it seems that ways/MP are getting more common.

    place=islet and place=archipelago

    For shure, eg. shetland islands are combined in one MP tagged as place=archipelago.
    I will prepare UK_Scotland and GB Map for testing.

    Here are the csv’s of all poly_labels with sizes.
    You will notice that (small) St.Kilda is tagged as archipelago and not as an island.

    EQ keys for sizes (same as bevore):

    bBoxWeight tiny 1,2,3,4,5,6,7,8,9
    bBoxWeight xsmall 10,11,12,13
    bBoxWeight small 14,15,16,17,18,19,20
    bBoxWeight mid 21,22,23,24
    bBoxWeight large 25,26,27,28
    bBoxWeight xlarge 29,30,31,32
    bBoxWeight xxlarge 33,34,35,36,37,38,39,40
    bBoxWeight xxxlarge 41,42,43,44,45,46,47,48,49,50,51,52,53,55

    @John: The IDs in the csv are internal IDs of the poly_labels and don’t match any ID of OSM

    zoom_appear: archipelago=6, islet=12, island=10

    Maps will follow.soon

    Will this be incorporated in the next release of maps?

    Yes, of course!
    Its a real improvement for the maps – thanks for this great idea!
