Re: [talk-au] Suspicious amount of removed bicycle tags

Hi all

I am thinking that OSM maybe could better confine itself to what can  
be ground truthed.


If a path exists, motor vehicles are physically excluded and that  
there is no signage

motor_vehicle=no highway=path

if there's signage then =designated or no

Its not for us to judge if the path is legally a footpath. Applying a  
bicycle=no is not even correct because under 12 year olds and  
accompanying adults can use it.


Let the map renderers and routing engines worry about the legalities  
which change over time and which apply equally to the same physical  
features and can be applied "globally" by them and let OSM concentrate  
on the ground truthed physical features.

Yeah, I?m aware of that. As far as I can tell, there is no legal   
difference between (unsigned) footpaths and (signed) Shared Paths in  
 regards to bicycles in Queensland as far as I can tell.




e.g.   
https://www.qld.gov.au/transport/safety/rules/wheeled-devices/bicycle#footpath




simply lists the two cases together as one.



On one hand, that makes bicycle tagging easy.



On the other hand, because of the equivalence, the local council, at  
 least in my suburb, doesn?t seem to bother putting up any shared   
path signs, despite the fact that some paths are by their   
construction (2.5m+ in width) pretty clearly designed as shared paths.




I noticed yesterday that some of them have this stamped on the   
surface every few 100m:

But, legally speaking, because of the absence of shared path signs,   
they are still footpaths.




Now, under the Australian Tagging Guidelines, I?m supposed to tag   
all of these as highway=footway as far as I can tell:   
https://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines#Australian_Footpath_.28no_sign.29




But I don?t think that really makes sense in this context because   
you do want the 3m paths perfect for cycling to stand out from the   
80cm footpaths.




When I started mapping my suburb donkey years ago, some of these   
larger ?footpaths? where mapped as highway=cycleway with various   
inconsistent tags on top. I?ve since standardized them to:




highway=cycleway

foot=designated (should that be only yes?)

bicycle=yes (to distinguish them from signed ?real? shared paths   
which are designated)


segregated=no



I believe this falls under the inverse of the rule:

Unfortunately, it is possible in Australia for a legally designated   
cycle facility to be completely unusable. A bicycle lane that is   
really a parking lane, or a shared path sign on a obstructed or even  
 non-existent path. Mappers should use common sense and discretion,   
and map the effective facility that exists on the ground if it   
differs to what is defined by the Australian road rules.




But, given that I think this situation (councils not bothering to   
put up shared path signs for paths that are clearly designed as   
such) is probably common in Queensland and other states where there   
is equivalence of unsigned paths and shared paths in regards to   
bicycle rules, maybe it would be worthwhile to reach some kind of   
consensus about this and document it in the ATGs?

& in Qld, at least, bicycles are allowed to be ridden on the   
footpath, unless specifically barred.




" Riding on the footpath
In Queensland, cyclists of any age are allowed to ride on a footpath  
 unless prohibited by a ?NO BICYCLES? sign. You must give way to   
pedestrians and ride in a manner that does not inconvenience or   
endanger other footpath users."




Thanks

Well, that pretty much matches what I said before:



Anything that remotely looks like a footpath (is meant for people to  
 walk on) is, in the absence of one of the 4 (3 + one mirrored)   
official signs I linked, a footpath.




It is not in any way limited to things that would be tagged as   
?sidewalk? in OSM.




e.g. take this example from my local neighbourhood:   
https://cdn.discordapp.com/attachments/558999688670609448/889134418067881994/unknown.png




In the absence of any signs saying otherwise (spoiler, there aren?t   
in this case) all of these are ?footpaths? as defined by law.

The upshot of the conversation is that we?re looking at ways to mitigate
our impact on the planet using something other than throwing money at
offsetters


Hi

I made contact with Parks Victoria (Australia). They are not in the  
business of providing carbon offsets but they would consider accepting  
money in return for agreeing to revegetate an area of land, resulting  
in carbon sequestration. The revegetation species mix would be  
carefully chosen to restore biodiverse bushland.


Contact me if you want to follow this idea up.

does anyone have any issue with using this suburb boundary shape file for
SA http://data.sa.gov.au/dataset/suburb-boundaries

a couple of notes;

1. this is not the same data as the ABS (see the .mht in the zip)

2. the shape file is released under CC license

Once I learn how to upload a shape file I will do it
