I came across an article with a map in our local newspaper yesterday via a Facebook post, and at once, I thought “Oh, this map looks very much based on OSM”. This map had been published by the local County Council and had no attribution (to any map provider). So before sending a strongly worded email (because it’s not the first time they used OSM data without attribution), I played a game of spot the difference comparing the published map with OSM and the Táilte Éireann (government agency) data. Here are just four things I found: map of Kilkenny

Their map data is from before July 8th 2023 which is when I changed the name of a road according to new signage, but they still have the old name on their map.

I think it’s very interesting that the local government continues to choose OSM over the government provided data (not sure whether it’s a financial issue or a data quality issue), but it would be very decent of them if they attributed correctly.

There doesn’t appear to be a resource available to aid in mapping The Mississippi Schools for the Deaf and the Blind, making it that much more important to map.

This diary entry serves mainly to help center my mapping efforts to the most important uses I can.

One of my current focuses is the University of Mississippi Medical Center. To my surprise, much of the campus was not mapped - specifically buildings and parking garages. I get it - it looks a daunting task and it is.

Resource

Thankfully the University shares a campus map which has helped greatly. I’m still in the process of mapping the buildings, roads, footways, grass, trees, and flower beds.

Purpose

Obviously mapping a medical campus aids those who need to navigate their way around the various buildings and facilities in an easy and efficient manner. Hopefully this allows those that come after me to:

  1. Build on this information, contributing more than I can.
  2. Add ways to utilize this data for helping others (apps, guides, maps, etc.).

Como corresponder as variáveis do CNEFE 2022 com as etiquetas do OSM?

O Instituto Brasileiro de Geografia e Estatística publicou a versão atualizada do Cadastro Nacional de Endereços para Fins Estatísticos (CNEFE 2022) e esta é uma proposta para correspondência entre as variáveis CNEFE 2022 e as etiquetas do OpenStreetMap.

Por Raquel Dezidério Souto (IVIDES.org e GeoCart-UFRJ)

O IBGE, orgão máximo da cartografia nacional brasileira, realizou o Censo Demográfico do Brasil 2022 e um dos produtos é a atualização dos dados do Cadastro Nacional de Endereços para fins Estatísticos (CNEFE 2022), que serve de referência para todas as pesquisas realizadas pelo orgão. Neste cadastro, estão integrados dados de regiões urbanas e rurais do país, mas o seu conjunto ainda apresenta inconsistências, que podem ser sanadas pelo mapeamento colaborativo.

Nessa via, o OpenStreetMap, a maior plataforma on-line de mapeamento colaborativo da atualidade, provê a estrutura necessária para a coleta e disseminação dos dados geoespaciais de logradouros, independentemente de sistema operacional ou equipamento do usuário.

Para realizar a importação dos dados do CNEFE 2022 para o OSM, uma das etapas de pré-processamento corresponde à compatibilização semântica entre as variáveis do CNEFE e as etiquetas do OSM.  Esta é uma proposta de correspondência entre as variáveis CNEFE 2022 e as etiquetas do OpenStreetMap (v. 5, 26 de dezembro de 2024).

You know what can really mess up carefully laid plans? What can even lead to a dangerous situation? When you get to the crossing of the South Fork Trinity River Trail and the East Fork South Fork Trinity River, a waterway that very much is still a river, and that bridge that someone has assured you they know is there is not there. There’s not even the evidence of once having footings for a bridge.

Apparently the mapper knew based on Bing aerial photography. Through thick trees. I can make guesses about how that crossing goes, too. At least when I guess wrong, I know it was a guess and might have made contingency plans around it.

Fortunately in the early days of Autumn, that ford I was LIED to about is just 4m of knee high wading without much current. That river comes out of some mountains that collect snow. It isn’t always so low.

The thing is, if it is important, it HAS to be correct. Your guess isn’t good enough. If it isn’t important, it can be left until someone who knows feels like doing it. There’s no renderer having trouble deciding how to render this crossing. It’s quite common that they aren’t specified.

I’ve been coming across a lot of guesses lately. I know they are guesses because they are wrong.

I was looking over an area I’d been working on when something started feeling wrong. It took me a couple minutes to notice that one of the roads I had aligned recently had sprouted four bridges. What? It was the unimportant spur of an unimportant low standard Forest Service road. They also get referred to as “unimproved” roads. We’re talking a road that might be produced simply by running a blade across the dirt. The whole thing probably cost a fraction of the cost of a bridge and suddenly it had four. Based on Bing imagery again, in which you can clearly see it is just a dirt road.

Загадка: Дом без окон, без дверей, полна горница людей. Что это?

Пишите свои ответы в комментариях :)

Сделал еще один такой: Ответ на загадку: Здание в OSM Кажется, это храм какой-то религии. На шпиле вроде был какой-то символ…

P.S. Надеюсь с высотой если и налажал, то не сильно :)

Ich habe ausgehend von einem anderen Projekt, fehlende Hausnummern in einem Ort entdeckt (Langenlipsdorf). Weil ich da aktuell nicht vor Ort sein kann, habe ich die Hausnummern vom Brandenburgviewer übernommen. Als Quelle (source) habe ich nun, wie auf den Seiten des Brandenburgviewer beschrieben den folgenden URL angegeben:

http://www.govdata.de/dl-de/by-2-0

Wie auf der Seite weiter oben beschrieben konnte ich im Brandenburgviewer keinen konkreten Datensatz ausfindig machen.

Frage: Reicht die Angabe des URL für den Source-Eintrag oder gibt es eine bessere Quellangabe?

Geofabrik OSM Inspector

何年か前には、広域森林などがよく壊されていた。 エラーチェックにOSM Inspector をよく使った。 近年は OSM Inspector を使っていない。機能が豊富なので、使いこなすのは簡単ではない。

左上の選択は 「Areas」とする。目下、横浜市泉区をマッピングしているので、そのあたりを 表示してみた。

かなり多くのエラーがある。OSM Inspector でエラーを見つけ、relation とか way などの osm_id を JOSM に入れて、エラーオブジェクトを表示する。

二つのポリゴンで描かれた公園の接合部にエラーがあった。合体させて、一つのポリゴンにした。

boundary=administrativeの一部が欠けていた。このエラーは多くある。 とりあえず、簡単な2件のエラーを修正した。

農地をouter polygonとするマルチポリゴンのエラーも修正した。

OSM Inspector にエラー修正が反映されるのは確か数日後であったと記憶する。

今回、4つのエラーを修正したが、まだ多くのエラーが残っている。 境界線エラーが多いと思われる。

誤って消されたとは限らず、分かる範囲で境界線を描き、不明分が描き残されているのかもしれない。境界線が交差のない閉ループにならなければ、エラーとなる。

道路や河川の県境などは現地確認できるが、詳細な境界線の確認には手がかかる。 残りのエラーのいくつかは後日修正するが、修正できないものもあるだろう。

行政境界線を強調表示する[2024.11.15]

日本地図全体では無数のエラーがある。横浜市泉区では、特に、行政境界線のエラーが多かった。いくつかは修正したが、簡単には修正できないものもある。

Hello OSM Community,

I’m currently working on a project to capture 360° images of the city of Salzburg for Mapillary, and possibly for Panoramax later. My goal is to enhance OSM data in Salzburg, especially in areas with notes that could be resolved with better visual context—something 360° images can provide.

Getting the Camera

I reached out to the OSM Belgium team to ask if I could borrow one of their 360° cameras. To my surprise, they informed me that there was already a GoPro MAX 360 in Austria! After checking with the local OSM chat, it turned out that mcliquid had the camera and kindly offered to send it to me.

Route Planning Challenges

Before starting the project, I wanted to plan an efficient route to cover as many streets as possible without overlapping - essentially the Chinese Postman Problem. Unfortunately, I couldn’t find a tool for this problem.

Initially, I tried bikerouter.de to created a GPX route. After importing it into OSMAnd, I found that it wasn’t working as expected - it tried to auto-route between the points instead of following the plan I made. This wasn’t practical for me for capturing 360° images.

The Solution I’m Using Currently

I eventually opted to use OSMAnd’s built-in recording feature. By activating the setting, I could record my route in real-time and have the GPX displayed directly on the map. This way, while cycling, I could instantly see where I had already been and decide on the fly which streets to cover next. This flexibility worked much better for capturing pictures around Salzburg.

Managing the Photos for Upload

From past experience, I knew that the Mapillary uploader struggles when handling too many files at once, leading to issues that require a full reset of the uploading-tool.

To avoid this, I used PowerShell to split the images into folders of 250 files each, which made the upload much smoother and basically error-free. This small step ensured that I could process and upload my imagery without hiccups.

Opis projekta

S obzirom da je riječka obilaznica (dionica između čvora Učka i izlaza Sveti Kuzam) ključna cestovna prometnica koja povezuje Primorsko-goransku županiju i grad Rijeku, odlučio sam se za opsežan i detaljan podhvat ažuriranja svih podataka ove autoceste. U planu je cjelokupno i detaljno mapiranje svih postojećih objekata i podataka te dodavanje novih detalja kako bi se karta uskladila sa aktualnim uvjetima i stanjem na autocesti.

  • Status: dovršeno
  • Autocesta: A7 Rupa – Rijeka – Žuta Lokva
  • Obuhvaćena dionica: čvor Učka – izlaz Sveti Kuzam, oba smjera
  • Početak: 1.10.2024.
  • Planirani završetak: 15.3.2025.
  • Završetak: 10.4.2025.

Projekt uređenja riječke obilaznice obuhvaća uređenje postojećih čvorova (ispravak ulaznih i izlaznih krakova), korekciju zelenih površina, zaštitne ograde i područja za akumulaciju oborinske odvodnje, uređenje postojeće signalizacije i uvođenje pozicija LED promjenjivih displeja iznad profila kolnika, ispravak ili ažuriranje podataka o trakama (broj traka, ograničenje brzine), uvođenje pozicija kamera za brzinu te nadzornih kamera sa direktnom poveznicom na URL kamera, ažuriranje daljnih cestovnih pravaca i odredišta na izlaznim i ulaznim krakovima čvorišta, dodavanje informacija o tunelima, duljini tunelskih cijevi, godini izgradnje i tehičkim specifikacijama iste prirode te uređenje svih popratnih površina, SOS ugibališta i odmorišta na području navedene dionice.

Uređenje riječke obilaznice provodi se u etapama kako bi se osiguralo da podaci odgovaraju onima sa terena. U samom početku provodila su se ažuriranja čvorova i njihovih naziva, potom dodavanje zaštitne ograde, nadzornih kamera i ograda za buku, pa ispravak pružanja čvorova, ulazno-izlaznih krakova, dinamičkih displeja te SOS telefona i aparata za početno gašenje požara u zonama tunela i odmorišta.

Projektom su obuhvaćeni:

Hei alle sammen (altså… dere som følger meg fortsatt og kan god norsk). Jeg har bestemt meg for å komme meg tilbake og hjelpe med kartredigering! Jeg hadde vært fraværende særlig lenge, men nå skal jeg ikke det. Jeg skal hjelpe med å oppdatere kartet der jeg studerer i utlandet (Denver i USA) og… trur det er alt da! Ha det fint dere :)

I recently finished this mini-project where I implemented the classic 15 puzzle game but using the standard OpenStreetMap tiles as the sliding pieces!

While there are many implementations of this game online and in app stores (some even let you upload your own image), as far as I know, not one directly uses OSM slippy map tiles for the pieces. I figured this would be a nifty side coding project and it was fun to do!

Currently you can play any of 20 map locations. Enjoy! 🎉

It’s that time of the year again, and once more, I find myself sharing my experience from State of the Map Nigeria 2024. Unlike last year, when we didn’t have workshops, this time we were spoiled with multiple workshops, covering various topics that kept participants actively engaged. Plus, for those who missed any sessions, we now have everything recorded and uploaded to our YouTube channel to revisit at any time!

Unfortunately, as the Programs Lead, I missed many of the live sessions myself. But during the few times I could sneak into a session, I was blown away by the depth and engagement. This conference had that special vibe, the kind that makes you wish it lasted longer. I’m confident that everyone who joined will be excited to return next year.

One of the things that stood out this year was the diversity in our participants. We had people coming from across the north, south, east of Nigeria, and even Ghana! Meeting new faces, like my new friend Calvin Menttor from Ghana, was an absolute pleasure. By the way, I finally got to see the Ghana cedi in person 😄.

To my Tech Crew, Joshua, and Justice, I must confess that I still mix your names up sometimes 😅, but it was a fantastic experience working with you both! Together, we made the media coordination a breeze (though, Justice, you did leave me to freeze by taking the duvet 😂).

Shout-out to my Logistics HoD, Olurunkosebi, and Welfare HoD, Titi. You both made my job so much easier! You ensured that meals arrived on time and that all the participants had a comfortable experience.

And I can’t forget Hajar from TomTom, who supported us with the mapping project used during the conference. Your contributions were invaluable, and we’re incredibly grateful.

Heatwaves have become a growing concern in recent years, and this year they’ve hit Bangladesh harder than ever, posing serious health risks. Our team, Three Dot, is competing in the Forewarn Disaster Hackathon 2.0, where we’re developing an app to provide heatwave alerts and an AI assistant that offers crucial advice on heat-related health issues.

One of the key features of our solution is providing users with the location of the nearest cooling centers—places with public accessibility, where people can cool down safely. These could be shopping malls, super shops, or mosques—any space that’s well-ventilated and free for the public to stay in.

The challenge we faced is that such attributes don’t exist in OpenStreetMap (OSM) for Bangladesh. Drawing on my previous experience as the former president of YouthMappers at Eastern University, I took the initiative to map out potential cooling centers. We’re tagging these places with: 1) Cooling_center: yes and 2) Cooling_center_bd: yes, to create a reliable resource for users and develop our heatwave project on top of that. Initially, our target location is, Dhanmondi and Mohammadpur.

Our initial focus has been on mapping spaces open to the community, such as large shopping malls and mosques, so that people can find refuge during extreme heatwaves, even if just for a short time.
