[talk-au] [EXTERNAL] Re: Many Sydney residential roads have incorrect surface of paved

Wed Jan 6 22:44:58 UTC 2021

Hello, I'm Kana from the Microsoft Open Maps team. I wanted to follow up on the points previously made in this discussion. All edits by the Microsoft Open Maps team have been made directly by our editors and were not applied by a computer algorithm.

When we added these surface tags around Australia, a few of our editors used "AI" as an abbreviation for "aerial imagery". We have since amended our changeset comments to avoid confusion with the more commonly-known abbreviation "AI" for "artificial intelligence."

Each road we applied surface tags to in Australia was viewed via one or multiple layers of aerial imagery to determine whether a "paved" or "unpaved" tag was more appropriate.  We wanted to leave more specific surface types to local community mappers with on the ground knowledge. If an editor could not determine a surface type with certainty, we would not add a surface tag to the way.

Please feel free to ask if you have any questions. I will add to changeset comments our team made featuring the term "AI" to clarify the situation for future discussions.

I've been reviewing the maps in Sydney and have noticed that quite a few roads have a surface of paved yet are actually asphalt when compared against Google Street View

As Kim implies, Google street view (or other Google products) cannot be used in OSM.

---------------------

Removing 'paved' and not replacing it decreases the data, so that is not a good idea.

If you want to add more detail then replace paved with the more precise value. The DCS NSW Imagery has the best resolution that may help determine which kind of paving has been used, of course a personal survey is best.
