Hey all!
TfNSW's recent waiver-signing gave us access to their Cycleways dataset
( https://opendata.transport.nsw.gov.au/dataset/cycleway-data ) which
includes shapefiles and information about cycle paths, shared paths,
cycle lanes, and shared lanes. The data is quite detailed ( see
https://opendata.transport.nsw.gov.au/system/files/resources/NSW%20Cycle%20Data%20Guide.pdf
) covering everything from lit= to operator=.
There's been discussions about this dataset and its place in OSM on the
OSM World Discord server ( https://discord.gg/q6HnfNZ #asia-pacific )
and we think we should present to you lot for discussion. Here's a
summary of the consensus so far:
- The metadata about the ways is useful in OSM, but the shapefiles
aren't accurate enough for an import. The data is also too old to be
considered for a direct import (some ways date to 2009!)
- The metadata, however, is extremely useful to apply to existing ways.
An editor could load up a separate layer, manually review the tags
before selectively copying them over, or compare the data with OSM to
highlight potentially unmapped ways.
In line with this, I've drafted an osmosis TagTransform file that can
turn the raw TfNSW dataset (after being run through JOSM's OpenData
plugin, for example) and turn it into the usual OSM tagging schema.
Check it out:

There's some notes at the top of the file, please read them! After
discussion on Discord, it's been changed to not output name, alt_name,
or cycleway:difficulty:tfnsw (a new tag to describe TfNSW's low, medium,
high ratings). ref:tfnsw - which is the OBJECTID inside the dataset - is
also being considered for removal.
This is also being written up in a wiki page:
https://wiki.openstreetmap.org/wiki/TfNSW_Cycleways_Data
That page has the procedures we've been using to generate an .osm file
to muck around with in JOSM.
Big thanks to aharvey and ortho_is_hot for helping out with this!
