- I love adding random stuff. I'm in #Ashburton in #newzealand so of course I have to add #SimsBakery midcanterbury.co.nz/location/s… to #openstreetmap using #streetcomplete - The best Cream Donuts - only matched by #SydnenhamBakery in #christchurch - #notanad

This study from MIT used geo data collected from cars in Milan, Italy, to check the effectiveness of 30 km/h zones in reducing speed.

The first conclusion is that the signs don't work: 85 percentile speeds are all over the place in 30 km/h zones in Milan, as shown in the figure below:

The second step was finding correlations between speeds and street features extracted from openstreetmap. Results are as expected: narrow, short, curvy sections correlate with lower speeds, as do 1 lane vs more, one way vs 2 ways:

The final step is also interesting: the authors made a model to predict the compliance of 30 km/h speed limit on streets that are 50 km/h at the moment. Useful for urban planning to understand if charging an area to 30 km/h would need structural interventions (like bumps, narrowing of the street...) or not:

There is so much more in the article, I suggest to read it fully.

I just got a new(ish) phone and am reinstalling all of the apps that I used to have on my old phone, and I remember that there was an app out there where I could type in an address, and then it would auto-open OSM by passing in the geo-coordinates. I cannot find this app again for the life of me. Does anyone have any idea where I can find this?

Ich als Vampir habe nun das @openstreetmap App was ich beim jetzigen Wetter wirklich benötige aber kann es noch momentan nur in Zürich nutzen.

I thought this was quite a nice piece about OSM and the humanitarian mapping team.

You may say this is basic or this is really nitpicking or micro mapping. But this is something that bothers me for a long time. So I'm currently mapping sidewalks in my village and according to this

https://wiki.openstreetmap.org/wiki/Guidelines_for_pedestrian_navigation#Sidewalks_and_crossings

What I should do, is to separate sidewalks from pedestrian crossings - so top and left of the blue dot is a pedestrian crossing and bottom and right is a sidewalk. Got it.

Now things start to be complicated (at least in my head) when StreetComplete starts asking me for the surface of that crossing. An example:

Now my mind starts to go to crazy and I'm not sure which option is correct:

1. Set the surface of that pedestrian crossing to paving_stones since that's the actual surface of that path. The fact that it crosses the asphalt road doesn't matter as that's the surface of the road

2. Split the pedestrian crossing into 3 parts, set their surface accordingly so paving_stones, asphalt, paving_sones. But all are still pedestrian crossings.

3. Split the pedestrian crossing to 3 parts, set only middle of that to be the pedestrian crossing as that's the actual crossing, set the other parts to be a sidewalk. Set surfaces accordingly

4. Similar to 3., split the pedestrian crossing into 3 parts, set only middle of that to be the pedestrian crossing as that's the actual crossing, set the other parts to be footways (so no sidewalks), since those are just separate footways connecting the sidewalk and the crossing. Set surfaces accordingly

All of those have some logic in my mind but I won't go to details as it'd be very long post. But I guess the number 2. is correct? Although I then start wondering what to do in case the sidewalk is right next to the road? Just setting it to asphalt?

Anyway, please help me bring peace to my mind - which one is correct?

You can sponsor our student mapping stars to attend SotM LATAM here.

A powerful video showing how Oaxaca communities document informal transport networks. We’ve added English closed captions so more people can appreciate this grassroots effort in action.

I have the OSMand app on the Phone for offline and survival use. Plan is to search for campfires in an easier manner.

Right now, I have to zoom in (quite a lot), in order to even see a campfire icon.

I want to simply click a tag that displays all campfires and yet be able to zoom out a lot to see all campfires in the area. Is this even an option or am I just a moron and don't understand how the app works? (Don't answer that last part ;D)

The Duitama Mapping Stars—a group of Colombian high school students—have digitized informal transport networks from East Africa to Southeast Asia to Latin America. Their work powers apps and planning tools that make cities more inclusive and mobility more equitable. Their edits and mapping efforts have powered our open source apps and improved the mobility experience for countless people.

Let’s make sure the world sees what community-driven, youth-led innovation looks like

Which maps can you recommend / do you use?

I'm looking for a map that has english names all over the world. Moreover a more beautiful world map would be awesome.
