There are lots of different types of easements.
Other than buried gas pipe lines there are;
buried optical fiber lines
over head power lines, and access tracks to them
public roads through property (farms, State Forests, National Parks etc)
private access through one or more properties to another private property
old stock routes (the long paddock) .. these can be see on the DCS base
map - e.g. Sturt National Park
And probably more...
The old stock routes cannot be 'seen on the ground'. Yet someone could
insist on using it.. they would need permission from IIRC the stock
board who usually imposes restrictions - start dates, minimum speed -
where stops are made and for how long .. etc.
Mapping what you see is fairly safe. Mapping an easement ... ? how wide
is it? There would be lots of questions about it .. I'd stay away unless
you have a formal source that can easily be checked.

Thanks for raising the issue, Graeme.
I opened the issue but I have limited understanding of what an
easement is in different jurisdiction.
Ben makes a good point in that an easement can be considered as an
absence of something else, so might not need to be mapped, more
specifically a space in between plots that can be built. Maybe why
there is so little of it mapped on OSM?
Where the note points, I believe the reason it exists is access to the
small bit of bushland and the creek, for emergency services for
example. In that case, should it be tagged as a track rather than a
footway? And what access tag should be used?
Cheers

If there is no formed track (but vehicles do use it) then I would
think that highway=track or path, surface=grass, visibility=no, low,
etc. and access=private, otherwise landcover=grass would be fine in
my opinion.
OSM is not a town planning serves it, it does not contain
zoning codes or laws so why should it contain easements?
Further to this, easements are a lack of ground structure (due to an
underground, overground, or planned utility/road), therefore not
having anything mapped on top of them would not cause a problem (and
the eagle eyed may think there is an easement there)

A note had been raised concerning mapping a Council access easement:
https://www.openstreetmap.org/note/2883145#map=19/-27.50901/153.03017
Suggestion was made that these should be leisure=nature_reserve
as it is not to be developed on?
I suggested that they're just highway=footway + surface=grass,
possibly with access=private if so signposted e.g:
https://www.openstreetmap.org/way/538670878
Alternative suggestion was landuse=easement?
Have just done some searching &, strangely, there are basically
no easements in OSM!
https://taginfo.openstreetmap.org/search?q=easement
The 13 "easements" are all in Australia for gas pipelines:
https://overpass-turbo.eu/s/1gXr,
while the 28 "easement_filed" are all in Florida for power lines:
https://overpass-turbo.eu/s/1gXs
The only other mentions of easements are in the wiki for US
Public Lands:
https://wiki.openstreetmap.org/wiki/United_States/Public_lands,
together with a brief mention in Massachusetts:
https://wiki.openstreetmap.org/wiki/Massachusetts/Conservation
So, how would we like to map these areas?
3 alternatives would seem to be nature_reserve / landuse or highway?
Any other suggestions / thoughts?
What do we all think?
Thanks
Graeme
