Hi David, it would help to understand if you posted your if/else clauses. The —add-pois-to-areas adds the tag mkgmap:area2poi=true to a newly created node, the polygon is NOT changed.

The natural=bay [0x3d resolution 18] is commented in my polygon style file. The —add-pois-to-areas adds the tag mkgmap:area2poi=true to every polygons. My if statement is based on this tag in my points style. I tried this trick because I thought elements were removed after lines, polygons and points style are applied. My inspiration is based on the fact I am able to create contour lines for forest polygons with the lines style. All my tests are made with Ireland and the bay involved is Clew Bay.
