Hi,

you can find a rather complete documentation of all mkgmap:* tags in the mkgmap style documentation (http://www.mkgmap.org.uk/doc/index.html). Please let us know if you miss something.

If you have a problem with a specific way I propose to use the following rule in the finalize block of the lines file:

osmid()=227105752 & highway=* { echotags "Wrong roadspeed?" }

This prints out all tags for way 227105752.

Hi,

I have observed weird road speeds when using current mkgmap r2977. See
this way:
http://www.openstreetmap.org/way/227105752

It has no maxspeed tag. It should be rendered as primary road, speed
class 4. This is what I get, if I disable including "roadspeed" file
from default style.

With "roadspeed" all is different and depends on tile area. I have
prepared sample data, where this road get speed class 6. Croping a bit
tile area (outside the road) changes speed class to 3. See picture
showing both cases, dark blue is class 6, green is class 3:

I have prepared an example of source data:
http://files.mkgmap.org.uk/download/172/speed-problem.7z

It contains source data and a poly file for cropping. I have included
batches, that I have used for creating maps.

Actually I'm not sure, what is the behavior of mkgmap:road-speed-class
tag. I couldn't find any description. For example if I define a road
like [0x03 road_class=3 road_speed=4 resolution 19], does it create
mkgmap:road-speed-class=4?
