Maps.me is turning to mulch too

Use Organic Maps - made by some of original authors, with nasty parts like trackers, data stealing and ads eliminated.

Thanks for writing and sharing! A very interesting article.

Nitpicking:

We just need to select the smallest number of large gravel zones that lie between our starting point and destination. The route with the shortest length of paved roads must travel through these zones.

is not necessarily true

@Adamant1 Yes! In fact processing all changesets ever made is relatively easy.

One of my current project is making analysis like this - to show lifetime of many users at all in a graphical form. I am curious who is using SC - new people? New people who become more involved - or stay on SC forever? People mapping already?

Not sure when I will do this but I can link some code processing this data if anyone wants.

I am also surprised that OsmAnd (my favorite navigation app) is a source of more edits than Vespucci.

OsmAnd has more users. Vespucci mappers has about 15 times more edits (by volume of edited objects which in this case should be comparable).

My area has lost work because of a bug.

Can you be more specific? There were some known data-damaging bugs but affected versions were blocked and all affected data was repaired.

It dumps “legitimate” tagging bloat.

Also here, can you be more specific? I am not sure is it complaining about deleting tags or about adding tags.

It simplifies complicated situations which masks places that haven’t actually been accurately mapped.

For which types of answers?

Is it case of mappers answering incorrectly?

I’ve mentioned some ICA commissions in original post, but you can find a full list here: https://icaci.org/commissions/

From looking at it - “OSM is doing nothing on any front” seems clearly untrue, unless by “is doing nothing” you mean “is doing nothing that I like” - like with QA.

It is not professional, it is not quality work, it is not representative. There is no point of even mentioning it.

It is a bit misleading and confusing to describe guidelines you dislike or consider as useless/harmful as “absolute lack of QA measures/guidelines”.

Even if it would be based solely on haruspicy then it would be misleading and confusing to describe it as “absolute lack of”.

I’ve mentioned some of a number of cartography commissions (“directions” if you wish) which ICA is busy with, OSM is doing nothing on any front.

Can you give some examples?

whole thing is rampaged by several clueless people

I think that proposing something specific and something that actually can be done would be a better solution than insulting people.

Or at least do both, just insults and vague complaints about everything getting worse are not going to change anything.

The actual problem is the absolute lack of QA measures/guidelines on this level.

On which level there is lack of QA measures/guidelines? Is it about tag creation/deprecation/use?

While viewpoint of “proposal process as it stands and ‘Any tags you like’ is harmful” can be internally consistent, claiming that there are is “absolute lack of QA measures/guidelines” is not consistent with reality.

I did some statistical analysis of this in Belgium a few years ago

Do you still have code for getting activity data from changeset dump and comparing with welcome message data?

Statistically speaking, there doesn’t seem to be an impact on mapper retention either.

Has anyone actually measured this? I would not be surprised if retention after one year would be 1% vs 1.1% - 10% increase but not noticeable for someone sending welcome messages.

This tool has now wiki page:

See https://github.com/osmbe/osm-welcome-tool/issues/171 osm.wiki/Welcome_tool

How this would look like if only more productive mappers would be shown?

Excluding people who made less than say 25 edits.

Maybe also excluding accounts which are blocked and/or number of edits is low compared to total block length (number of edits smaller than blocked days * 10). But that is likely not impacting much.

And maybe also plotting blocks would be interesting.

they commit to regular editing sessions in which they are active for across multiple hours

I would expect StreetComplete mappers to end here often, despite low number of edits and low impact.

For example I likely register as very long mapping session nearly every time I leave home.

(I am also likely ending there due to my habit of making small edits in rotation with other things, despite that this edits are tiny tagfliddling tasks like osm.org/changeset/114152146 where I remove descriptive name - equivalent of landuse=garages name=garages)

Comparison of solar power locations on OSM (blue) and those predicted by Kruitwagen (dark red)

Maybe green for one in both datasets would be nice?

Gratulacje!

But isn’t that what is already happening with all the other big polygons imported from CanVec, like woodland data?

Forest multipolygon with thousands of elements are also mistake that should be fixed.

I would still straighten Derry St because it looks better and it should be that way. Derry St has much higher functional classification and should not be compromised. The angle should be okay still after that.

Oh right, it ended being moved a bit. I straightened it now.

The parcel owner has the rights to say no thru traffic when the road is also owned as private. So no problem doing that.

The problem is whether this restriction is actually applied (some people map nonexisting restrictions and I worried that may happen here)

access=customers should be used. No free parking there (yes you will be towed).

Done!

I also fixed shape of road on parking, added parking itself (with access=unknown, feel free to detail it if you are familiar with this location), added missing parking aisle.

I tried to preserve

• topology (which is useful as you point out, though rhetoric is a bit extreme)
• road shape
• intersection shape

At cost of deviating from strict centerline matching (what is often done, for good reasons)

osm.org/edit?editor=id#map=21/40.26140/-76.85723

PS is access=destination an actual legal restriction there?
