    Hi, I’ve noticed a potential rendering order issue in Elevate (most recent version) with Locus. It does not occur with the Voluntary theme.

    I think heathland is being rendered above forest at closer zoom levels. I’ve attached some screenshots from the Great Britain map, UK grid reference shown on the photos (Lake District, just below Harter Fell). The forest is lost when you zoom in.

    That’s a case of bad mapping; we have two landcover sections that are overlapping. The forest ist displayed completely up to ZL 11. When the heath is displayed starting with ZL 12, it covers the forest because it is drawn later in Elevate. With correct mapping the landuses shouldn’t overlap. To correct this this huge natural=heath should be turned into a mulipolygon which leaves out the forest parts (and maybe other landuses):

    I used to draw landuses transparent at high zoom levels, but this also had this issues and mapping got better so it wasn’t that often necessary anymore.

    One workaround for this case would be to draw forest later and heath earlier, but usually in the areas I use Elevate the forests are larger and heath smaller, and with incorrect mapping like this heath would still be visible if it’s just a small island in a huge forest.

    Thanks. I’ll have a look some point at correcting the maps then. I noticed a few examples in Wales also.
