[mkgmap-dev] How to show land and see

Wed Jan 7 17:26:02 GMT 2015

Hi Andrzej,

your suggestion to revert back to the last working version
brought me directly to the solution.

I had 2 maps in the same directory with the same TYP.
All changes I made to the TYP of one map where ignored.
The device just took the info from the TYP of the other map.

The second error I made:
When I deleted the prio of the default background 4b,
TypViewer automatically gave it the lowest prio again.

Now my sea is back, I'm having a custom background
via Polygon 0x10000 and one command in Style,
natural=land  [0x10000 resolution 14]

I could not bring it to work with the default Background
Polygon 4b, but I don't care about that.

It's working and I'm happy.
Thanks a lot for your support.

Best regards,
Walter

PS: Now also the overview map is working correct and visible.
I am wondering, where mkgmap takes the info about the whole world.

Hi Walter,

some clarifications: object 0x4b is a special kind of polygon, it is
used as a map background and covers whole map area. You should not use
it in style, because it is created by mkgmap (except for transparent
maps). You can use polygon 0x4b in TYP to change background color of a map.

Priorities that you set for polygons in TYP actually are draw orders.
Polygon with draw order 1 is drawn before polygon with draw order 2. If
polygons overlap, then polygon with higher draw order will be visible.

I can't guess why you have problems with sea. I suggest that you revert
to the solution, which worked for you and then only add polygon 0x4b to
TYP file, without draw order or with lowest draw order.

Andrzej
