How to hide notes?

On the OSM website, how do I hide the note icons? I made them appear by using the 'Add a note to the map' button but I can't remember how to hide them again.

3D Buildings

Hello everyone!

I'd like to build some 3D models in OSM (some churches for example) but with JOSM or iD it is not really visible, if the changes I am doing make sense. Is there some WYSIWYG-Tool for building 3D related stuff? Thanks in advance!

Geofabrik Datas

I'm trying to create a database of all municipalities (cities, towns, villages, hamlets) in Italy with the following information (using this file italy-latest.osm.pbf ) :

  • Name
  • Coordinates
  • Region
  • Province
  • Type (city, town, village, hamlet)

But I'm really struggling...

I'm using the Geofabrik italy-latest.osm.pbf file, but I can't seem to extract provinces and regions with osmium.

So far, I can only extract 64,000 rows that include the filtered place types and coordinates, but nothing else.

I'm new to these technologies, especially osmium. Does anyone know how to help me extract the province and region associated with each row?

extremely frustrated with overpass syntax and documentation

Hi. I need to work on all the driveways within a hospital that is geographically delimited within a multipolygon.

Every single time I need to work with Overpass Turbo, I get the same frustration. The syntax is... what is is, and the documentation is... what it is.

What I want to do is select ways with certain keys (access=*) that are located within the geographic boundaries of a multipolygon relation.

Do you have better guides to suggest than the documentation at https://wiki.openstreetmap.org/wiki/Overpass_turbo ? I find it to lack structure, consistency, logic.

Thank you.

Access denied when importing OSM data via osm2pgsql into Postgres 17

Hello,

I am out of my wits end. And it seems so simple. I have Postgresql 17 installed with postgis extension and created a database OSM_Netherlands with owner postgres. Simple.

On a different drive I have installled Osm2pgsql, which includes the default.style file and the data to import (europe-latest.osm_01.pbf).

When executing the following command, I get the error Access denied (in Dutch: Toegang geweigerd, to be precise):

osm2pgsql -c --slim -S default.style -C 400 -d OSM_Netherlands -U postgres -W -H localhost -P 5432 europe-latest.osm_01.pbf.

It seems to me something related to Postgresql, but the owner of the database is postgres, so that shouldn't be any problem.

Furthermore, I have done this in the past several times with no such error. Just two weeks ago I bought a new PC, with newly installed Windows 11 Pro. Are there any windows settings that I overlook? Or other advice?

Any help is welcome.
Kind regards,
Pim Verver

Magic Lane (Magic Earth) sing up page not working

I couldn't find a dedicated reddit forum for Magic Lane so I am posting here since the app uses OpenStreetMaps. I am trying to sign up with Magic Lane

https://developer.magiclane.com/api/register

but after I fill out the fields and click on "Get Started" button nothing happens. I tried using a different browser but no luck. I sent an email to the company and I am waiting to hear back from them. Has anyone else experienced the same issue and how did you resolve it?

How to tag a library with both staffed and self-service hours?

Library that has both regular staffed hours and self-service (unstaffed) hours. To enter the library druing self-service, a library card is needed. During this time some services like printing are not available.

Should I include self-service into opening_hours or leave it out completely.

Here's an example of a typical day: Self-service 6-11 Staff 11-18 Self-service 18-21

Weird Routing on Valhalla... anyone know whats going on here?

Hi Folkes.

I'm doing some work playing with valhalla routing and have come across a bit of a corner case which also appears in the open test area of valhalla.

These three routes all end at the same place but start just a few metres apart and the route returned are wildly different (like by a factor of 10 in distance)

Any thoughts on what could be going on here?

Best way to tag Historic Landmark Plaques?

California (and many other places) has a registry of official historical landmarks. Each of these is recorded on site with a variety of different monuments, but each of them has a metal plaque on the site indicating te registry number and a brief inscription about the historical significance of the landmark.

What's the best way to tag these sites? The landmark itself should be getting the historic=* tag, to indicate that detail. But there are some locations that don't have a physical object to indicate beyond the plaque, such as "first landing of ...".The plaque is not a memorial for an individual, so memorial=plaque does not seem to fit. These are landmarks, but landmark=yes doesn't properly apply to the plaque, nor is that indicated to be best practice for appropriately communicating the significance of the place. Nor does historic=epigraph really fit, since the inscription isn't a direct park of the landmark, nor is the plaque itself historic.

Is there a consensus to the best practice here that I couldn't find? Am I wildly overthinking this?

Google Map and OSM data doesn't match, also OSM road nodes doesn't align with Google map route.

Google Map

OSM Map

Hey guys, I have a question about this. When I try to compare OSM data with Google Maps, I notice a lot of differences, and I’m not sure how to correct or resolve them. The OSM nodes don’t match with Google Maps, even though I’ve used the Google Maps API to check the most up-to-date version. How can I fix this? The reason I ask is that I’m trying to create a routing algorithm for navigation, and Google Maps is more up-to-date than OSM. Some locations have already changed, and if I rely solely on OSM, there will definitely be issues. So, I’m wondering if there’s a way to solve this problem. Thanks in advance!

Does Josm have a shortest path plugin.

I have an osm file that I extracted from a dataset that contains only waterways.

If a mass of connected waterways are unnamed, I would like to select a point at each end of the waterways and for Josm to select all the ways between following the shortest point.

Is this possible without creating a routing layer which I assume involves considerable work.

Overpass Turbo Assistance - Query to Find Geographic Extreme Points

Can anyone help me create a query in Overpass Turbo that finds the geographic extreme points within the municipal borders of a city.

I'm having a hard time figuring out the best way to structure a query that would find the northern-most, southern-most, eastern-most, and western-most points. Thanks in advance for your help!

What is the cheapest suitable 360 camera?

I noticed that my town is almost not represented on KartaView and decided to buy a cheap 360 camera, stripe it on my helmet and ride around on a bike. I know they accept images from regular cameras but I would like to make it "the proper way".

What cheap camera would be good enough? Currently I'm inclined towards QooCam Fun that I found selling used for 50 USD. Would it be good enough? Are there better options?

How to create geojson of buildings in a neighbourhood

Hi, Im trying to get a vector point file for buildings in a neighbourhood that I can pull into geojson.io and edit as a polygon.

Ive read the reddit and got myself to overpass and osm, but I think Im not running the wizard query for overpass right. Ive tried type=building but nothing highlights? However I think the meta data is just there, just not the points.

Any help would be great!

No house numbers in my town

I mostly use the map for street numbers as it’s more accurate than google. But for some reason my town does not show them at all. I have tried via OSmand app and directly on the web and it’s the same.

The town is Widnes, Cheshire.

Also is there a way for me to start adding them in?

Edit: Cheers for all replies so far, this could be my new hobby!

How out-of-reach would be having our own satellite imagery?

It surely is expensive to buy satellite images with a right to sublicense (I only found prices for small areas for internal use online, and if they scale the total for the whole planet would be over a billion dollars). Doesn't really line up with 776261 USD OSMF's 2024 budget.

But how crazy would be launching our own satellite?

Or maybe we should switch to areal photography with drones? Maybe we can find enough volunteers to cover most of the land.

Maybe some government would decide to release their photos to public domain?

Get only one point for each roundabout ?

Hello,

I'm new here, and not really a good programmer

I wanted to test Overpass Turbo and so I try to get the roundabout In Bruxelles in Belgium.

But I wanted to get one point for each roundabout and it seems to give me more than one point. And I don't see the difference between the two round about in pictures below. I firstly thought it was because of the difference between roundabout and mini_roundabout, but apparently not. Do you know why I have more than one point ?

The main idea is to get like the picture 2 one point for each roundabout and transform the seven points of the picture 1 into one point within the query.

Here is my query : https://overpass-turbo.eu/s/1XiG

Thanks in advance for your answer.

PS : I may have made mistake as english is not my first language

[RFC] sensory_friendly

Hello r/autism! Your wonderful mods have allowed me to make this post to request feedback on helping to make the map more useful for the sensory-sensitive.

I am an avid contributor to OpenStreetMap, which is a massive, crowdsourced map used in part by all the big names you know like Google, Apple, your city government, and pretty much everywhere you see a map online.

Historically, we have had markers we add on the map (called nodes) for those with physical constraints (such as those in wheelchairs with ramps, accessibility, curbs, etc.) It’s 2025 and it’s about time our maps start sharing sensory information as well. As such, I have made an initial proposal to introduce 2 keys which can be added to a map location:

  • sensory_friendly which can have a value of yes / no / hearing / vision / balance / smell / touch / taste.

  • sensory-friendly hours to display alongside the opening hours of a location if the location has designated sensory-friendly times of not all day.

Link to the formal proposal

Link to our discussions thus far on the topic

I would like some feedback from potential users of this data on how it can be of better utility or if this type of information being present on maps would be useful.

As an example, after reading through this community, I am thinking adding crowds as an option would be a nice addition to indicate less crowded or crowd-limited times.

Thank you all in advance for your feedback! This is just the first step and I hope to build upon this foundation in the future!

Level crossing suppression and OpenRailwayMap?

ORM marks existing railway crossings with a red X and inactive crossings with a black X. OSM doesn't seem to have the option to mark a crossing as removed, though, only to delete it. Will deleting a crossing on OSM create a black X on ORM, or will it disappear altogether?

Simulated Panorama View from OSM Data?

Is there a website / app that can simulate a panorama view from a / for a location on the map?

I'm thinking of something like this: https://wiki.openstreetmap.org/wiki/Creating_a_panorama_with_OS_OpenData , ideally with annotations for certain POIs like peaks or settlements (similar to touristic panorama outlines of mountains with named peaks)

Routing website non-standards

Thanks to "those" maps for some inexplicable reason no longer working in Firefox 115.18.1esr, I've started to use Valhalla and GraphHopper , and both work well, although I find the fact that the former returns coordinates that are probably accurate to a micrometre, a bit over the top, so I round them to just seven decimal places, which should result, correct me if I'm wrong, an accuracy of 1 cm. I'm also a bit disappointed that Valhalla limits the zoom factor. (But I do like that both allow, at least for now, 20 (Valhalla) and even more, not tried to find the limit (GraphHopper) "via" points)

However, I've hit a (minor/huge) snag when I try to compare results from both websites, in that for some incomprehensible reason they use different formats, in casu, swapping (expletive deleted) longitude and latitude. Obviously when accessing the data programmatically, it's easy to cater for this difference, but pity the poor soul, aka me, who uses Cut & Paste of lat/long - long/lat pairs, to get routes that either don't even display, or are totally wrong.

So why the flucking 'ell couldn't these two organisations agree on a standard, set by "those" maps, lat/long format?????

First time editing a map, can anyone help.

I'm not sure if I'm doing it correctly. If I post my profile link would you be able to check whether I've correctly edited an existing hiking trail that needed correcting?
