Depending on the zoom level, the CycleOSM Layer is corrupted with a large number of false straight roads. I’m looking at a region near Angers, France.

Someone is littering openstreetmap with streets that do not exist. A Russian hacker is the cause and one other person.

In January, I introduced Overpass Ultra v2. Today, I’m pleased to announce some updates to further improve Overpass Ultra’s customization capabilities, enabling you to make custom maps like this one:

Loading queries from URLs & Gists

In order to facilitate sharing updatable overpass queries&maps, Overpass Ultra is now able to load queries from a URL or Github Gist.

To use this feature, specify either query=url:... or query=gist:... in the hash parameters. For example to load a Gist:

https://overpass-ultra.us/#query=gist:02ab2139d146dd2ee0306a38d96a9c9d

or to load that same Gist with the more flexible (but more verbose when using Gists) url: option:

https://overpass-ultra.us/#query=url:https://gist.githubusercontent.com/dschep/02ab2139d146dd2ee0306a38d96a9c9d/raw/8d4b0d38eac64e8dbd772284d4cc094708cd3b26/gistfile1.txt

I was recently asked how I find and review notes on the OSM US Discord (you should check it out!).

I use the following links to see recent notes. This one is all note actions, last 1k notes: https://resultmaps.neis-one.org/osm-notes-country?c=United%20States

This one is only open notes. It is only opened, commented and reopen actions. You can see the last comment. https://resultmaps.neis-one.org/osm-notes-country-custom?c=United%20States&query=open

I start with the most recent notes and work my way back. The notes can vary wildly. Some are onosm.org ones where a business submitted a request to be listed and all that is needed is to validate it exists, the tags are correct, and it is correctly located (according to reported address), and then you add the business w/ appropriate tags. Some are to identify an error or addition that is beyond the editor being used. Some are clearly spam (Ex: Give CurlingMan13 a beer and a raise!), but you get a feel for it after a while.

Now before I submit that single changeset, I look around the map in that region and search for other notes that I can resolve (some are related, some are easy).

Another good source is NotesReview. You can search for specific text, age, specific users, etc. This one is really good if you want to kill off the oldest notes. https://ent8r.github.io/NotesReview/

its been 4 days i see this lines like exploded roads … when zooming map location , i tried showing amusement park when editing , it also showed exploded road lines hope ( OSM Servers ) Are fine , and its necessary for a company to do monthly backup for all data

take a look at picture:

This celebration of 126th Independence Day as a July 12.

Today I mapped Lavdar i Korçës which according to OSM data has a population of around 1152. The village was not very big, and I was quite motivated today, so I moved to another village close to Lavdar.

Polenë, according to OSM data, has a population of around 752. Did not fully map it, but I think I might have mapped around 80% of the buildings. To my surprise, the streets were mapped pretty well.

I do hope I can continue to map daily for the next 4 days because I will be volunteering at WordCamp Europe in Torino. If I do not manage to map, I will catch up when I get back home.

Overview

This was the mapping with haved the a #Mapping101 via Bagong Pilipinas

Today i mapped two villages from the list, Mokricë-Zleushë and Tenë.

Mokricë-Zleushë is a small village in Përmet. It is a tiny, remote village which also seems quite far away from the other villages around.

Tenë is a small village in Rrëshen. Another tiny, remote village far from the main road.

I would like to check how far from these remote villages are the closest schools, medical centers, hospitals, main streets and the closest city. I know it is possible leveraging OSM data and most probably QGIS or even JOSM (not sure about this). If anyone got some good tutorials and would not mind sharing, i would deeply appreciate it. Unfortunately, i do not have time currently to deep dive into either of those apps.

The link for the public version https://sdm.etica.ai/v/0.5/ I made an effort to make it easy and very cheap to host (currently is a client side static vanilla JavaScript+HTML app) and, as a side effect, the privacy of your data is kept.

Since I joined OpenStreetMap in 2022, I’ve done some tools without a graphical interface, and this one I’d love to receive feedback from potential users on such a very niche topic.

Already at early versions of it (I stated a prototype in 2023 mere debug for the real conflation done non interactively before load on OSM editors), I truly attempted to think how to make it as a plugin for JOSM or think how to extend iD instead of keeping it side-by-side with iD or alt-tabbing with JOSM.

The good news: It does have basic support to use one or more files to match by distance and/or by tagging with the one or more target files and then you download the geojson. Okay, addr:street would need language and country level comparison (because misspellings), and also addr:postcode may already have logic to tolerate near matches. If you know vanilla JavaScript to code a function to your country, then it could be more forgiving.

The bad news: for points of interest, the so-called “edgematch links”, “rubber shedding links” or whatever the term to be use to export file “these 0-N items in dataset A matches these 0-N items in dataset B” necessarily need human-in-the-loop and it happens in unpredictable ways. And links which aren’t obvious 1-to-1 (while there’s room for suggestion) require need human input. It started as the “typical leaflet” plus a text-only, but we might need a way to visualize N:M links (unless any you have an UI suggestion to plot such links already over pins in a map!).

I first heard about the OMGuru Fellowship in November 2023 at the FOSS4G conference in Bangkok. Intrigued by the opportunity, I applied and was thrilled to be selected for the mapping fellowship. What followed was an incredible journey of learning, growth, and impactful experiences.

During the fellowship, I was introduced to various powerful tools such as JOSM, RapID, Mapillary, and the EverDoor app. Each of these tools enhanced my mapping skills and broadened my understanding of the technological landscape in the field of geographic information systems.

A significant highlight of the fellowship was participating in a climate change competition. This ongoing challenge provided me with hands-on experience using MapSwipe and MapRoulette and allowed me to lead a team, further honing my leadership and collaborative skills.

Over the past five months, the fellowship has not been without its challenges. Natural disasters such as an earthquake in Papua New Guinea and floods in Afghanistan required urgent mapping efforts for response activities. The OMGuru Fellowship equipped me with the tools and knowledge to contribute meaningfully to these efforts, opening doors to real-world applications of my mapping skills in crises.

The OMGuru Fellowship has been a transformative experience, providing me with invaluable skills and the opportunity to make a tangible impact. I am grateful for the support and guidance from OpenStreetMap and APHub, and I look forward to continuing my journey in the world of open-source mapping.

Introduction

Hello, fellow mappers! I’m excited to share my experiences as a part of the Open Mapping Guru Fellowship program for 2024. This journey has been an amazing mix of learning, challenges, and making a real impact in the world of open mapping.

From OSM Beginner to Validation Fellow

My OpenStreetMap (OSM) journey began in October 2021 during a training organized by the Geomatics Engineering Students’ Association of Nepal (GESAN). I was immediately drawn to the collaborative nature of OSM and its ability to create free, up-to-date maps for everyone. I wanted to do more than just make edits. That’s when I found out about the OM Guru Fellowship, which has tracks for Mapping, Training, and Validation. The Validation track really interested me, and I was lucky to be selected for it. Knowing that my work helps create reliable maps for disaster response, humanitarian efforts, and other important uses gives me a strong sense of purpose. It feels good to know that behind every useful map, there are contributors working hard to make sure it’s right.

Fellowship Experience:

Being a part of OM Guru Fellowship was more than just learning new skills; it was a transformative experience. The fellowship made me think critically about data quality and gave me more knowledge of powerful validation tools. From OSMCha and Osmose for thorough quality checks to MapRoulette for fun task completion, I learned to find and fix errors precisely. Each task was a new challenge, keeping me engaged and helping me improve as a validator.

My Learnings:

The biggest lesson I learned from the fellowship is the power of collaboration in open mapping. Every validation task, every discussion and every challenge shows the collective effort that goes into creating high-quality maps. It’s humbling to be part of this global network of passionate individuals, all working towards the same goal – a more accurate and accessible map for everyone.

My Achievement

Kastriot is a village located in Peshkopi, and it has a population of around 6000, according to 2011 population statistics.

Three years ago, I was tasked to send volunteers for a door-to-door campaign in support of a local independent candidate from the miners for the parliamentary elections. Almost every village in the region was visited, but I wish I had the knowledge of OSM I have today. It would have been so much help. I spent so much time on the maps back then that these villages feel like home, even though I have not visited most of them yet. I am glad, I am finally mapping this villages now.

Maybe most of us have experienced unpleasant situations with maps, like getting lost on the road due to navigation issues caused by incorrect or outdated maps. This problem is particularly troubling in unfamiliar areas or during long journeys. Poor geospatial data quality often leads to these inaccuracies, resulting in significant inconveniences and even potential dangers. This highlights the crucial role geospatial data plays in our daily lives; when it is inaccurate, it can lead to serious issues.

Geospatial data quality depends greatly on who creates it, especially on platforms like OpenStreetMap (OSM), the world’s largest open mapping platform. OSM’s data comes from many different contributors with different levels of geographic knowledge. This diversity can enrich the data but also lead to heterogeneity. For instance, in the picture below, you can see the differences in digitizing done by various contributors. Some highways are more detailed, indicated by the higher number of nodes in the highway line.

Hello OSM community,

I’m excited to share my experiences as a participant, validator in the OM Guru Fellowship, 2024. This program has been an incredible journey of learning, growth, and community engagement.

My Journey

Before joining this fellowship program, my experience with OSM was primarily limited to downloading OSM data and using it in GIS software. While I knew that I could edit and contribute to OSM, I lacked the practical knowledge on how to effectively edit and contribute data.

From the moment I joined the OM Guru Fellowship, I knew I was embarking on a unique adventure. The fellowship provided a structured platform for me to enhance my mapping, validating skills, collaborate with fellows and contribute to meaningful projects on HOT Tasking Manager. One of the highlights was working on HOT Tasking Manager Projects, where I learned the HOT Tasking Manager plays a crucial role in leveraging the collective efforts of a global community of volunteers to improve mapping data where it is most needed. It supports humanitarian organizations and local communities in making informed decisions based on accurate and up-to-date geographic information.

Learnings

Throughout the fellowship, I gained a wealth of knowledge. I improved my technical skills in using various OSM tools, learned not only effective mapping techniques but also creating & contributing at HOT Tasking Manager Projects. The mentorship and trainings/ workshops were particularly beneficial, offering insights into best practices and innovative approaches to mapping. I also learned the importance of community collaboration and how collective efforts can lead to significant outcomes.

Hello, my name is Julmira de Almeida. I'm one of the Open Mapping Guru Fellows in 2024. First of all, I am deeply grateful to Open Mapping Hub Asia-Pacific for offering me this brilliant opportunity to participate in the Open Mapping Guru Fellowship. This is my first time participating in an international fellowship activity while pursuing my studies at the University. As a young woman who is highly passionate about mapping activities, participating in this fellowship is extremely significant. I have many opportunities to learn and further explore the various open-source platforms we can use in mapping activities.

This figure illustrates the process of capturing street-level imagery using Mapillary.

Introduction

The Open Mapping Hub - Asia-Pacific (AP Hub) aims to create a sustainable OpenStreetMap (OSM) ecosystem, engaging governments, humanitarian and development agencies, underrepresented sectors, businesses, and citizens in the open mapping movement. In early 2023, AP Hub started the Open Mapping Guru Project to create a network of skilled OSM contributors who help build communities by sharing skills and creating training materials. By the end of 2023, this project expanded into a Fellowship Program from January 2024 to May 2024. This five-month Fellowship aimed to develop the skills, knowledge, and capacity of Gurus through intensive guidance and training, focusing on making impactful contributions to the open mapping movement in the region. The program had three tracks: Training Fellowship, Mapping Fellowship, and Validation Fellowship, each focusing on different aspects of open mapping. I have been an active mapper since 2020, continuously contributing to various projects. As an Open Mapping Guru, I chose and also got selected under the Validation Fellowship to sharpen my validation skills and deepen my knowledge of data quality.
