Hi Graeme,

 

It also needs to be recent footage as lots have changed in the last couple of 
years (at least in TAS) and much of my old Mapillary footage would now be out 
of date. I would personally filter any town speed imagery by the last 12 months.

 

Cheers - Phil

Just looking at some of the work that's been done, I also have some concerns 
that a lot of this is based on Govt data, not actual road reports.

 

A couple that stand out to me are 
https://www.openstreetmap.org/changeset/161546799 & 
https://www.openstreetmap.org/changeset/161332341, with that one in particular 
spanning half of NSW! They must have a very busy driver reporting to them that 
day!

 

Also noticed https://www.openstreetmap.org/changeset/161043708 in Qld, 
apparently based solely on 
https://www.data.qld.gov.au/dataset/speed-limits-for-state-and-local-roads/resource/a733d0a2-3164-4c63-b2f6-01ae491356f0,
 which, when you open it, says Speed: 100, Sign_Num: Unsigned. I would have 
translated that to no speed sign which should then mean no limit posted in OSM?

 

Bob3Bob3, are you able to comment at all on side road speeds, as you've been 
out that way: https://www.mapillary.com/app/?lat=-27.88184393155384 
<https://www.mapillary.com/app/?lat=-27.88184393155384&lng=150.3552983872255&z=19.80526275306296&pKey=866587440868417&focus=photo&x=0.4890568269273885&y=0.5948579482782078&zoom=0>
 
&lng=150.3552983872255&z=19.80526275306296&pKey=866587440868417&focus=photo&x=0.4890568269273885&y=0.5948579482782078&zoom=0

 

I'd be much happier if they were basing their changes on actual dashcam 
footage, rather than Govt reports.

 

Thanks

 

Graeme

Hi Mark,

 

Well at least that user name may provide some detail on who the actual company 
is behind the edits

 

https://www.novasystems.com/au/what-we-do/global-alerting-platform#gap

https://www.linkedin.com/in/harsimranjit-kaur-253a00196/?originalSubdomain=au

 

If they continue to make incorrect edits (after changeset comments mentioning 
the errors) then I suggest another word to DWG

 

Cheers - Phil

I’m just following up on this. I haven’t seen the promised Wiki page regarding 
these edits.

 

Harsimranjit Kaur’s last edit was 17 June 2024. Another user started doing 
similar edits starting on 8 July 2024. 
https://www.openstreetmap.org/user/Nova%20Systems%20GAP

(Or is it the same user with a new account?)

 

I’ve found one problematic edit from this user - 
https://www.openstreetmap.org/changeset/160414255

Msxspeed through Nimmitabel had been updated in 2021 following an official 
change of max speed from 60 to 50.

Maxspeed was still 50 when I travelled through Nimmitabel in Nov 2024. (I had 
deleted my voice recording file after doing these edits, but found the voice 
recording in a Time Machine backup to confirm this was correct.)

Maxspeed was changed to 60 by this user. (I’ve reverted this change tonight.)

Sources for other changes by this user was "based on NSW Speed Data”, no source 
was given for this change, and the user has not responded to my query. I looked 
at the NSW Speed Data site, and it has maxspeed=50.

 

I haven’t checked the other edits (now up to 149 changesets)

 

I’ve had a look at the NSW Speed Zone interactive map, and have noticed a few 
incorrect speed zones in places.

They responded a few days ago but, as we're travelling atm, I didn't have a 
chance to do anything about it.

 

Their response:

 

"We sincerely appreciate your efforts in bringing to our attention the 
organised edits rules and guidelines, of which we were previously unaware. We 
acknowledge the necessity to adhere to these guidelines and commit to creating 
a wiki page for our organised edits accordingly. However, we kindly request 
some time to complete this task. 

 

Regarding our compliance with other editing rules, we are confident that we are 
fully adhering to them. It's important to note that our system utilises tools 
that rely on OpenStreetMap data. Upon discovering numerous discrepancies in the 
NSW speed zone data within OpenStreetMap, we initiated edits to rectify these 
inconsistencies.

 

Our editing process follows a detailed verification procedure, outlined as 
follows:

 

1.      A driver reports a speed discrepancy on a specific road.
2.      The driver report undergoes thorough verification and is escalated for 
further examination.

3.      We utilise NSW Speed Data 
(https://opendata.transport.nsw.gov.au/dataset/speed-zones) to verify the 
reported speed limit.

4.      If the claimed speed limit aligns with the NSW Speed Data, we proceed 
to update it in OpenStreetMap.
5.      Conversely, if the reported speed limit does not match the NSW Speed 
Data, we reject the claim. However, if multiple drivers report the same speed 
limit discrepancy over time, we request evidence from the drivers, often 
resulting in the provision of images depicting posted speed limit signs. Based 
on this evidence, we update the speed limits in OpenStreetMap accordingly. 

 

We are eager to address any discrepancies that other mappers may have reported 
concerning the edits we have made. Could they kindly provide us with evidence 
to facilitate a detailed investigation? This will enable us to reassess and 
update our map editing processes as necessary.

 

Our primary objective in making these edits is to enhance the experience of our 
drivers and community. Therefore, we welcome any suggestions or further 
discussion that would contribute to ensuring the accuracy of our edits."

 

Don't know if that answers the questions you have?

 

I've suggested that they set up an account here to talk about what they are 
doing.

 

Thanks

 

Graeme
