I added several extra parts to Hamel Street, which I had to name, because apparently there hadn’t been a name available on it. I added several houses, and will add more soon.

I added data to the Mauritania mapping for the agricultural component of the UN. Most of these appear to have been a result of the shape of the landscape, around the farmland.
I think that next time I will use the Josm tool.

A style using the Shortbread vector tiles is now live on OpenStreetMap.org. There’s been some minor issues with the roll-out, but nothing that caused me to panic. I’ve been taking a couple of days to unwind and relax, as this has been a major milestone.

A feature like this includes work across multiple projects, so people have been asking where to report issues.

1. Any issues that are present on the OpenStreetMap website but not on the vector demo page should be reported to openstreetmap-website. Some issues reported have been with attribution controls and strange panning at extremely high zooms

2. Style issues (e.g. colors, symbology, fonts, etc) are handled by the VersaTiles Colorful and VersaTiles Eclipse styles. Both can be found in a VersaTiles repository.

3. What is supposed to be in the tiles is defined in the Shortbread Vector Tile Schema 1.0. There are lists of what features should appear, and where they should appear.

4. The code responsible for what is actually in the tiles is contained in the Street Spirit repo. If something is missing that is supposed to be in Shortbread, this needs fixing. This also handles simplifcation and other parts of generating the tiles.

5. The software that serves the tiles is Tilekiln. If the wrong HTTP headers are being sent, this is where you report it.

6. The chef code pulls everything together on the OSMF servers. It’s unlikely you should report an issue directly here.

7. Some font rendering issues are part of MapLibre GL JS. This is most likely to come up in Southeast Asia.

Many OSM validators will report an error if a waterway crosses a highway without some additional tags or structure at the intersection, such as a bridge, culvert, or ford. That makes a lot of sense if you’re working in an area where the roads and waterways are already well mapped and where the waterways are actually wet. Those assumptions might work well in Europe, for example. They don’t work well in the Southwest United States.

Of the possible resolutions, adding a node with ford=yes is the easiest, so many mappers will do this to satisfy the validator – sometimes without looking closely at the situation. Then you get results like this, where the ford=yes nodes are meaningless.

If you get a warning from a validator that a waterway and highway intersect and need additional tagging, there are some things to consider first:

I like to map trees. Last year, I wrote a diary about trees mapping, a wiki page to document tagging of Italian monumental trees tagging, a trivia thread about the tallest trees in the database etc. In this diary, I’d like to focus on quality assurance (QA) checks we can perform on tree data. Many of these checks have been turned in MapRoulette challenges in my Tree Validation project.

Measures 📐

• Circumference

The circumference=* tag is used to describe the circumference of a tree’s trunk at a height of 1.3 metres above the ground, with the implied unit of measure being metres. Therefore, circumference=2.3 describes a trunk with a circumference of 2.3 metres.

According to the Guinness World Records, the greatest circumference for a tree is 43 metres. Trees with circumferences exceeding this value are likely errors. Often people forget that metres is the standard unit, so they tag using centimetres, creating giant trees. E.g. they tag circumference=650 instead of circumference=6.50.

• Height

The height=* tag is used to describe the height of a tree in metres. Therefore, height=15 describes a tree that is 15 metres tall.

Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world’s tallest known living tree, measuring 115.92 m. Trees with height exceeding this value are likely errors.

• Specific species measures

You can refine the above checks using known limits for individual species. For example, according to monumentaltrees.com, the biggest circumference for a Tilia cordata is 12.81 (instead of 43) and the tallest specimen is 41.60 (instead of 115.92).

• The “slenderness ratio”

The height-to-circumference ratio can be considered a form of “slenderness ratio”: lower values indicate stocky or stout trees, while higher values indicate slender or spindly trees. This can be helpful to find wrong circumference or heights.

Slowly working to edit and add information about public infrastructure, along with surveillance information.

I haven’t written anything in this diary yet, so I decided to just do that.

I have no idea any more when I first heard of OpenStreetMap. What I do still remember is the time where I didn’t know how to make changes myself. I noticed this mostly back around 2015 when I was using a GPS navigator based on OSM data, and often it didn’t bring me to the precise location because of missing house numbers. This wasn’t too bad, I was in the general vicinity, and I could mostly figure out where to go from there, but it was annoying, and I do remember two occasions where the same street was actually separate parts, making it hard to find out where I needed to be. I was thinking that it would be nice if I’d knew how to add those house numbers. Some I encounter along the way wouldn’t be much, but if everyone does a bit, a lot can be done was my idea.

Somewhere in 2021, I met Pieter who is very active in the Belgian OSM community, and he was nice enough to give me a deep explanation of how it all works and what tools there are and what I can do to contribute. I decided to write this explanation down in a blog post, and from that moment on, I started to contribute to OSM. I was also pleased to hear that the house number problem I was having, was mostly a problem of the past, as the government released the needed data under a compatible open license, and people of the community are making sure the data is put to good use.

April 15–19, 2025, proved to be a special landmark in my mapping experience when I participated in the OSM Spring Mapathon 2025, sponsored by Youth Innovation Lab. I am excited to announce that I won the Beginner Category for 22,922 map changes!

This acknowledgement is meaningful to me—not only as a personal achievement, but also as a personal reminder of my growth since first hearing about OpenStreetMap (OSM) during 2021. At that time, OSM was merely another name, still learning its way into my periphery. Little did I realize the meaning that OSM would take on as an important part of my learning and contribution trajectory.

I committed a certain amount of time each day during the Mapathon to updating map data. Anything from adding roads, perfecting building footprints, or fixing map glitches and errors. Each change adding to a sense of satisfaction that somewhere someone would benefit from finally going through something that they could map out into a community, and their community becoming visible, sharing their data.

The event itself was inspiring. While Youth Innovation Lab was the primary host, the Mapathon brought together fellow mappers from across the land, and beyond. Each day’s schedule created an exciting and competitive environment that made staying sedimentary contagious.

Though I did not expect to win the Beginner Category, I am even more so grateful. The motivation of this experience is further proof that with the appropriate due diligence, sprinkling curiosity and learning, anything is possible!

Hi guys!

Quick midterm update from me! Just as a little refresher, my name is Anqi and I’ve been working on the Transliteration of Search Results project this summer.

Time has really flown by and we are at the halfway point! Here I hope to give a summary of the work that’s been done so far, as well as what I hope to accomplish during the next part of the summer! We want to be able to return the transliterated name as a field during search results, with a proof of concept shown here! We can see in this proof of concept that the results are as expected, with the addition of one transliterated name field.

RETEX: My Urban Recycling Trekking

To be continued, maybe:

• diary entry (upcoming): choosing tags for this trekking
• diary entry (upcoming): existential questions about my encounter with Panoramax

Context

Since April 2025, I’ve been discovering OSM and trying to contribute wherever I can. Needless to say, I’m learning something new every day about OSM mapping (thanks to the Wiki, forum, and fellow contributors).

While exploring my neighborhood, I added a voluntary drop-off point (for recyclable — though not always — waste) to OSM, located 800m from my home. I then discovered that the local intermunicipal authority has an app listing a large portion of the collection points. I wondered whether it was legally and technically feasible to retrieve those, and whether it would align with the OSM ethos.

The forum quickly (and kindly) set me straight (as I said, after only 2 months with OSM, I’m learning a lot every day):

• Extracting data from a website’s database is obviously illegal unless there’s an explicit license that allows it.
• Even if there were a friendly license (which is not the case here), it would still need to be ODbL-compatible to import the data into OSM.

This led me to pursue two parallel paths:

1. Finding a sustainable solution via an open data source, which means:

   • Trying to convince the intermunicipality to publish its data, ideally on www.data.gouv.fr
   • Convincing them to make this publication sustainable (i.e., generate an export every time there are updates)
   • Assessing how, in theory, this data could be used (completeness, attribute matching, duplicate detection, handling conflicts between open data and on-the-ground data — which can either be better or simply incorrectly entered)
   • Finding out how and by whom the data could be imported
   • Seeing if all of this could happen before 2035

2. Starting manual mapping myself through field visits (the foundation of OSM’s truth)

As you might know, we’re having OpenStreetMap Awards this year! Finally, after many skipped years, we will have the honour and the joy to recognize people and teams who have made an impact on OSM, whether it’s by mapping, writing, or coding!

The process is open, and the same as the last time: first we gather all the nominees we can think of, then some groups of notable OSM members will choose a few from those who feel to be the most notable, and after that — an open community voting to choose one for each category. And the categories are:

• Core Systems Award — for building or maintaining an core project.
• Innovation Award — for making something new.
• Influential Writing Award — for blog posts, tutorials and documentation.
• Greatness in Mapping Award — for tireless mapping!
• Expanding the Community Award — for finding us more members.
• Team Achievement Award — awarded to companies and groups.
• Ulf Möller Memorial Award — like a lifetime archievement award for individuals.

Note that only achievements made or announced in 2024 or before April 1st, 2025 are eligible.

And right now, I need you help. The deadline for submitting nominees is looming, and we’ve got too few. Each category needs at least twenty to make sense, and for some, we got like two.

This needs some archive work. Like, open WeeklyOSM or big community discussions (before April 1st), and add people, projects, and teams you think made the OSM in general slightly better.

And submit them to https://awards.openstreetmap.org/

(Yes, we’ve got the official domain, thanks to Grant!)

July 20, 2025 - After 17 months, I have reviewed every road in the NFSR network for the Siuslaw National Forest. Below is a summary of what was involved and the process I used.

Foundational elements

The foundational elements of this project are two public domain road datasets, the NFSR data from the United States Forest Service, and the OR-Trans dataset from the state of Oregon. NFSR is the reference for road numbers, names given to roads by the USFS, road surfaces, and geometry to a certain degree. The OR-Trans data is a reference for primary road names, geometry verification, and the tag formatting of USFS roads. I was able to use additional GIS from counties to verify geometries and primary road names.

Project management

QGIS was utilized as a way to manage the entire project. I used conditional styles on manually added attributes to break the 1,977 roads from the NFSR data into workable chunks, and to keep track of what I had done. Those workable chunks were exported as KMLs to use as a reference when working in iD.

Edits on OSM

I elected to use iD for this project to force myself to manually review everything I was doing, and to remove the possibility of an accusation of a careless import.

The NFSR data contains good geometry for the most part, but there are quite a few errors that are very significant. The NFSR data also contains several discrepancies from reality, such as roads being marked as closed and not open for use, despite the roads not being gated and definitely being actively used. Blanket replacing the geometry and tags in OSM without manual review would worsen the quality of OSM data.

This was also a good opportunity to do some TIGER cleanup and resolve road/water crossing issues. Unfortunately, with the nature of the crossing issues, resolving one can lead to getting flags for multiple others along the road or waterway, which can make it appear that you are creating these issues even though they were already present.

In 2020, I was presented with an opportunity to participate in the Humanitarian OpenStreetMap Team’s Data Quality Internship, https://www.hotosm.org/jobs/data-quality-internship/,a twelve-week program designed to facilitate deep engagement within the Humanitarian OpenStreetMap Team and its community while acquiring transferable geospatial skills.

Commencing on August 3rd, I undertook a three-month internship that concentrated on Geospatial Data Quality within the Humanitarian OpenStreetMap Team. The primary objective of this internship was to prepare interns to evaluate data quality, execute mapping and validation tasks, and provide constructive feedback to mappers engaged in HOT’s remote mapping initiatives, which included various activations. This experience necessitated the acquisition and application of both novel and established OpenStreetMap Quality Assurance tools to enhance the quality of data within the OpenStreetMap framework.

-Data Quality Assurance with QGIS

1. Downloading OpenStreetMap data into QGIS

https://youtu.be/Mvh5l0PiOiE

1. Editing OpenStreetMap data in QGIS

2. Using Map Composer

-Mapping and validation on Tasks e.g #8294 and #9194

-Introduction to Overpass Turbo and Umap: filter OSM data, extract/export data

-Improving data quality with Overpass and creating simple webmaps using Umap

• The graphic interface and tools for creating a basic map layout through the manipulation of vector data

-Quality Assurance Tools such as OSMCha, OSM Inspector, Keep Right and Osmose

-The use of Map Roulette and Map Paint Styles

• JOSM training i.e mapping and validation using JOSM, task #9055

Questions

1. Does OSM track the last time a user made an diary entry?
2. Does the last map edit timestamp on a user’s profile indicate only the edits made to maps or diaries and notes as well?

https://osmand.net/blog/15-years/

Most of our mapping parties, if not all, start with a brief introduction. The newbies are informed about the various benefits of using and contributing to OpenStreetMap, such as massive improvements to the individual’s privacy and an easy mechanism to correct data.

However, I have been wondering if this approach is the optimal path. This doubt started nagging me after I picked up The Theory of the Leisure Class by Thorstein Veblen. If class distinctions are really so pervasive as theorized in the book, shouldn’t we try to incorporate these findings in our promotion of OSM in mapping parties and everywhere else?

A clear description of the context would be in order. Though our existing method of extolling the benefits of OSM is good, I don’t think it is the best one for India. India has, unfortunately, one of the lowest proportion of people contributing to social activities. In conversation with my friends, I often find them considering the idea of “doing something for free” repugnant. Maybe its due to the oppressive nature of the Indian classes, where people’s aspirations are mostly reduced to the singular objective of rising above their current class. Whatever is the reason, we can at least conclude that the current system of promoting OSM is unsatisfactory in the context of India.

We can, for instance, try to frame OSM as a hobby and actively compare the intensity of mapping activity with other mappers (say, by focusing on the heat map that is displayed on the OSM profile page). Setting aside the moral considerations this entails, I believe this approach is likely to bring some interesting results. People may or may not be excited by the idea of increasing their reputation by performing conspicuous leisure in the form of contributions. However, it must be tested on field before we derive any conclusions.
