    Hi, often the areas of national parks, large swamps, and/or touristically interesting areas disturb the view of details in these areas (Openandromaps, Elements LE, Locus Pro). Example see screenshot1. Nowadays, there was a large “swamp area” added in this area, so it is a mess to recognize anything else in this area (not shown yet on this screenshot). Swamp areas were often introduced in a very rough way, so details like lakes and others lay behind the “swamp”. Example1, Example2

    Often I would like to prevent the display of these 3 types of areas.

    After choosing a render theme like “elements LE”, I can select/deselect the display of certain groups of map elements. For instance, when I deselect “borders + special areas” and “tourism & culture” (screenshot2), national parks and touristically interesting areas are not shown any more. But at the same time other details, like borders or touristically interesting points, are also lost.

    Would it be possible to switch off exactly these 3 surfaces in a targeted way, and nothing else?

    Thanks for your suggestions. I won’t introduce any specific on/off switches for just one tag, as I want to limit the switches to a reasonable number. I already think they are a bit too much. And the mapsforge overlay switch system doesn’t support submenus.

    But there are other solutions:
    – Wetland: is painted pretty early in Elevate, so e.g. lakes are above it and don’t get lost. Also wetland has transparency, so e.g. forests with wetland above are still visible. If you have any area, where real problems exist, please post screenshots and at best provide OSM links.
    – tourist=attraction: I think it’s wrongly mapped here (in conjuction with the national park), but anyway – in the next version, tourist=attraction won’t be visible when the same area is mapped as national park etc. Also it will be limited to the highest zoom level as it is defined in the maps. There is a bug in mapsforge where other tags are already visible as a defining tag, here national park. The latter is wanted at this zoom level, the first is not, that’s why some tags have to be limited in Elements as well – just cautiously.
    – Protected areas pattern: I already thought about introducing an overlay switch which combines all “special areas” which aren’t real landcover. But I think sometimes it makes sense to switch off borders as well, e.g. when a hiking path is on a border or a river, and it’s better visible without. But I don’t really want to introduce a “border only” switch. We’ll see..

    I have solved this problem for myself by restricting the display of the swamp areas to the zoom levels zoom-max=”14″. If I keep zooming in, the swamp surface is gone.

    If necessary, I deactivate “Borders + Special Areas” and “Tourism + Culture” if I do not want to display the areas of national parks and areas of Tourist attraction.

    Great that you solved it for yourself. I would still be interested in problematic areas, so any links/screenshots would be welcome.
