[mkgmap-dev] supershort ways - creating routing problems on some devices

Hi Felix,

I fear I don't understand. Do you want that this combination of steps and footways is somehow made more attractive
for cyclists?

Betreff: [mkgmap-dev] supershort ways - creating routing problems on some       devices

Hi Everyone,

with my style
https://www.openstreetmap.org/way/111528845
this micromapping of steps is creating problems for autorouting. It would be great if there would be a way to force join ways below XX meters to the next longer way (or other way around).

Basically here someone mapped ways 1-2m long - so it's a 2m piece of highway=footway, then 2m highway=step step_count=1, then again 2m of highway=footway, then 2m of highway=steps, step_count=4, then 1m long highway=footway - and then finally a little longer highway=steps with 11 steps.
Now there is no way right now to simply drop the highway=steps and join it to another way - as in style we do not know what the other way actually is.
Optimally here either highway=steps is removed and all made highway=footway (footways often have steps) or the other way round - the short footways become highway=steps and the footway pieces thereby removed.
It would be good to have a filter remove ways shorter than XMeters - and do the joining (maybe needs a separate file for rules? I guess mostly such ways are highway=steps anyhow however).

With my map this causes garmin devices to freeze. With others it's fine - but this micromapping really serves not much. On the other hand of course we cannot remove the detail from OSM in the database.

The remove-short-arcs options once did something similar - but it's ben deprecated.
