[mkgmap-dev] Feature request: Layer control

Thu Oct 11 12:25:36 BST 2012

Cutting out holes will be the best solution off course. In case of the
riverbank and fairway multipolygons, fairway has also to be considered as
the inner multipolygon of the riverbank. But for the buildings it will be
more complicated as there are more tags involved.

I really hope you can find a solutions for this problem. The Openseamap
project will provide a lot more waterdepth information (crowd sourced and
from official sources) in the near future. In my eyes all this is useless
until we can render shaded depth areas on a Garmin chartplotter.
