[mkgmap-dev] New branch for default typ file

From Gerd Petermann gpetermann_muenchen at hotmail.com on Tue Dec 10 09:59:38 GMT 2019 

Hi Joris,

the file mapnik.txt says "Based on mkgmap default style version: r4262"
Is it the right file?

reg. line type 0x0b: highway=motorway_link & (mkgmap:exit_hint=true | mkgmap:dest_hint=*)
I want to look at the DestinationHook. If I got that right it should be OK to have a zero-length road with that type to get the wanted destination hint. In that case we don't have to care about rendering.

Gerd

Hi All,

I don't think any changes needed in mkgmap itself. When the draworder of bay is lower then water it will display correctly.
See attached new typ-file for correct usage.
Even better (but this is a change in default style): don't use natural = bay in polygons but only in points for displaying as name.

Today I spent some time testing and repairing.

The mapnik.txt in branch mkgmap-default-typ-r4268 was pretty old and also did not have the translations of all the languages anymore. It also lost draworder of a lot of polygons which made the bay-problem occur.

I did a complete recheck of the most recent default-style in: mkgmap-r4386.zip and changed de typ-file accordingly.

I downloaded a full europe-latest from geofabrik today, builded it as a big full europa map with the default style of r4386  and with mkgmap r4386.jar No errors occured.

I think it’s up to date again but some review and comments are always welcome.

See typ-file in attachement,

Kind regards,
Joris

Hi Gerd

Yes, you can do that with a draw level 1 higher than sea.

Draw orders are defined at the beginning of a (txt) typ file just before the polygons

using the following format

Type=0x type number , draworder

It is good practice to sort the draworders , as that is how they appear in a typ file

[_drawOrder]
Type=0x03,1
Type=0x28,1
Type=0x54,1
Type=0x01,2
Type=0x09,2
  Type=0x4E,2
  Type=0x10F1C,2
etc etc
[end]
I have no idea what the draworder for sea is , but just make it one higher
