Hello
Do I understand correctly, that there are still problems with multipolygons?
Lakes marked as inner ways of multipolygon having forest as outer
way are still not rendered. Some of those lakes appear as a hole in
forest, some have no influence on rendering (lakes are displayed as
forest re

Yes, thank you, I've added that relation and will test the map
generation tomorrow (after geofabrik publishes todays data)!

I will try fixing the data (while fixing 4500 lakes in tiny
territory of Lithuania will not be a small task:). Just from my
experience adding multipolygons is quite a challenging task for
beginners, so I will have to come up with some automated way of at
least identifying such forest+water combi
Hi Tomas,
may first guess would be that a multipolygon relation (with role=outer
for the forrest and role=inner for the lake) is missing.

OK. Thank you all for answers!

I agree. The areas on the Garmin should be drawn by the drawing priority

Assuming that the data is correct, I can confirm that you need to set
draw order in a typ file.
I encountered a similar issue with building and landuse polygons. I
had to set a higher draw order so that buildings are drawn over
landuse.

the data is wrong in the first place. a lake and a forest can't be in
the same place. the forest should be created as multipolygon with all
the lakes as inner ways.
if you ask the software to fix bad data it will fail on some corner
cases and will succeed in some places. but then random eff

No, I am not. And some lakes marked the same way ARE visible on the map...

Do you use a custom typ file for your map?
If yes you can define the drawing order of the polygons. In your case you
should give the lakes a higher order than the forests so that the la

I've noticed strange problem with lakes (natural=water) in a middle
of forests (landuse=forest).
Some of them are displayed on Garmin (Colorado), some are not. The
only difference in data I can see is that the ones displayed have
