for some time now I wonder about malformed polygons rendered for buildings by mkgmap. It’s probably a misconfiguration on my side, but I can’t find a handle:
While using JOSM (or “official” OSM renderings) e.g. a church may have several small, more or less rectangular jutties, recesses and the like, its representation by
building='church' [0x0B level 2]
(from polygones) seems to render with missing (but also seemingly “new”) nodes, hence triangular shapes and overall malformed buildings, although the basic shape is there. To some degree this applies to many buildings having small displacements of sections. It even occurs if buildings are clustered (building at building, but with some parallel offset; the offset part renders malformed).
So far I could not identify the effect for other polygones, but it might be due to node density or proximity typically beeing higher for buildings.
Is there a parameter accessible I could tune to deal with that effect? (Toolchain: geofabrik downloads - osmconvert - splitter - mkgmap)
P.S.: Unfortunately I’m not able to attach screenshots or the like here, or how would I do that? I guess, the image tag accepts links only, does it?
