2. Administrative boundaries clutter the map. They appear like roads and can be confusing while driving.

Agreed - do they have to be there at all? I can understand that maybe country boundaries should be present, but minor admin boundaries are a PITA.

Could the minor boundaries be displayed on close zoom levels? They can be useful when the neighbour of a large city is mostly agricultural. It's often nicer to ride a bicycle in rural areas, on minor roads with little traffic or intersections. Marko

Hi Toby, all, and sorry for replying to an old post. On Thu, Apr 16, 2009 at 03:57:41PM +0100, Toby Speight wrote:

I have this in my style/lines:

/------ | boundary=administrative | { name '${left:country}/${right:country}' | '${left:county}/${right:county}' } | boundary=administrative & admin_level<5 | boundary=national [0x1e resolution 17] | boundary=administrative & admin_level<7 | boundary=political [0x1d resolution 19] | #boundary=administrative [0x1c resolution 21] | boundary=national [0x1e resolution 17] | boundary=political [0x1c resolution 17] \------

I haven't really tweaked it to my liking, but it shows the principle.

I adapted this for the default style last week. However, http://wiki.openstreetmap.org/wiki/Relation:boundary says that relations are used in order to avoid "name:left name:right, nation:right, region:right." I did not investigate if such *:left and *:right tags have been used in place of left:* and right:*, but I would like to remove the rules for left:* and right:* and solely rely on the relation names (one relation per country/province/city/suburb etc.). Seeing unnamed "State border" lines on the Garmin map should encourage mappers to define boundary relations. What do you think? Should I remove the rules for left:*, right:* names from the default style, or should I just add a comment to the effect that "these are deprecated, see the 'relations' file and wiki/Relation:boundary"? Best regards, Marko

The boundary relations weren't in (common) use at the time I wrote that rule; do we have a way to get the relation values onto the lines? If so, then great. As to whether to deprecate the above, or just remove it, I have no strong opinions.

Thanks for chasing this up - and I though /I/ was a long way behind with reading this list!

I had to tweak a few things in mkgmap to get it to work correctly, but now the default style does apply the names from the relations. Very well, I will remove the left:*, right:* that I added to the default style shortly before learning that they are deprecated. Marko
