We’d like to inform you that OptimoRoute is conducting an organized editing activity starting in late November, focused on improving the accuracy of truck access information across various regions in Australia. Our primary focus will be on editing existing ways to add missing constraint tags such as maxheight, maxweight:hgv, and similar.
You can find more information about our project, including objectives, data sources, and editing techniques, on our Organised Editing page.
We welcome your feedback and any questions you may have. Feel free to contact us at osm@optimoroute.com.
A question though when you say “Use government-issued maps and datasets in combination with publicly available information in OSM tools to identify missing information”
Where are you getting the data from, thanks, & what licence has it been released under?
Thank you for the question. Government-issued data serves solely as guidance for identifying areas of interest. The actual tag entry is based on Bing Streetside imagery available within the OSM iD editor, which is properly licensed for this activity. I hope this answers your concerns.
As noted on our Organised Editing Page, we primarily use Bing Streetside among the imagery integrated in the iD Editor, but we may consider Mapillary as well in areas where it provides more current coverage.
We’ve actually received feedback from our users about mixed coverage in areas such as Sydney. Based on this feedback, we re-prioritized Australia to start earlier in our project than originally planned.
I had a brief look at the sign recognition for maxheight in Mapillary. It detects the yellow diamond shape signs okay, but not the larger black on white. Indeed some of the black/white ones were privacy blurred by mistake.
There is an object API in Mapillary that might be worth looking into. ie dump the location of all maxheight signs. I don’t know how the terms of usage works for that but I understand an application and login is needed. Mapillary/Sign overlays are also available on iD.
Weight limit signs are also recognized, but I couldn’t remember any places I had been that had them to check!
Regarding Mapillary, a quick check in the Sydney area does show decent coverage of major roads. However, residential streets—always the more challenging ones to cover—seem to have far less coverage.
Here’s an example of a good resource for one area within Sydney that allows for relatively quick identification of missing tags: City of Ryde - Heavy Vehicles.
Sorry, I haven’t been able to get back to this over the last couple of days.
Unfortunately, that’s a perfect example of the problem I mentioned earlier - that page is copyright Ryde Council, & we (OSM) do not have a waiver allowing us to use their data: Australian Data Sources - OpenStreetMap Wiki
Have you obtained a waiver, or any other permission, to use their copyright data?
Hi @Fizzie41,
To clarify, we will not be using that publicly available example list to enter tags into OSM, nor will we process that data programmatically or use it to make conclusions about required OSM edits. The list serves solely as guidance to help identify areas of interest. All OSM reviews, conclusions on missing data, and edits will be based on licensed Streetside imagery, with signs identified as not having appropriate tags.
