While visiting the family down south, I had a chance to join UP Mindanao’s own chapter, UPMin YouthMappers while their College (of Science & Maths) was celebrating Pi Day. The coordinator asked if I have any preference for the name of the activity we had in mind, and I suggested Map-Pi Day.
I’ve been kind of bouncing around various projects the past week.
I have tentatively completed sidewalk mapping in Emsworth Borough, and have moved on to adding sidewalks and pedestrian crossings in Avalon. I also did a little revamp of the playground adjacent to the Avalon Elementary School. It turns out that as I was extending the sidewalk along California Avenue, I met up with some previously mapped sidewalk bits, which is nice. Although they have not added a lot of the tags I do, so I will circle back to make this area a little more seamless with what I’ve added to the west.
I’m planning to go through Ben Avon and Emsworth to tag pedestrian crossings and curbs a little more consistently; I had been changing the way I tag things as I went based on new information/methodology.
I got kind of distracted when I realized that Pittsburgh Botanical Garden needed some updating due to their recent renovations. I was able to add the new visitor center and update a lot of the concrete paths, but I have some question marks as to the accuracy of some of the other paths on the property. I will take some good GPX tracks the next time I am there (likely this week). I especially want to see what progress has been made on the feature that is to the southwest of the Lotus Pond. I will also try to acquire a more precise/accurate/official property map from PBG, because the pictoral one on their website is great for ordinary wayfinding, but wholly inadequate in precisely showing where things are.
There’s lots of data stored in OSM about bus stops, but often maps and apps created with OSM data don’t make much use of it (with OsmAnd being the notable exception). For here’s a bus stop as shown by OSM Carto:
You can see that it’s a bus stop, and you’d be able to see the name if you could zoom in a bit more. However, in OSM there’s actually lots more information. For the map styles that I look after (both web-based raster maps and for Garmin devices) I tried to add a bit more detail. Here’s the result:
Today I decided to introduce a new format for sharing OpenStreetMap-NextGen development progress with the community. I’ll post weekly/bi-weekly updates highlighting changes and the current project status. Since this is the first update, I’ll cover some recent highlights.
You can subscribe to my diary updates on RSS: link.
I’ve begun migrating the settings/preferences section. My goal is to streamline this experience, as I’ve found the current system a bit complex. Surprisingly, many users don’t know it’s possible to change the default editor — I want to make this more obvious.
A new menu on the left of the screenshot (hidden, not yet finished) will provide clear navigation between general, 2FA, OAuth, and other settings.
This page is still work in progress. I intend to add a help text explaining how to contribute to translations and that the translations are made by the community.
As we commemorated International Open Data Day and International Women’s Day, we embarked on a journey to intertwine these essential themes for equitable development. On Saturday, March 9, 2021, amidst a global celebration of Open Data Day, our event in Rwanda stood as a beacon of empowerment, bringing together over 50 enthusiastic participants eager to delve into the world of open data.
Before delving into the event’s highlights, it’s crucial to acknowledge the significance of Open Data Day. With more than 60 events worldwide, it underscores the global community’s commitment to promoting open data’s usage and accessibility. Thanks to the support from key funders, including the Open Knowledge Foundation, these events serve as catalysts for change, fostering collaboration and innovation.
Last quarter, a “getting to know you” survey was made available to the local OpenStreetMap (OSM) communities in the Philippines, to help us better understand the current state of the active contributor base of our community.
The original idea was to run it just for the membership of local YouthMapper Chapters (YMC), but eventually it was made available to anyone who contributes to OSM in the Philippines, here or abroad, regardless of citizenship or affiliations.
I’m sharing my observations from the responses made by the participants who participated in the survey, again, majority of whom comprised of local YMC respondents.

While 86% of the mappers reported that they are physically in the country, mappers coming from elsewhere at 14% was bigger than I expected.
The YouthMappers UFRJ (Rio de Janeiro, Brasil) completed one year on March 14th, 2024.
And to celebrate this special date, we interviewed Dr. Rogério Luís R. Borba, analyst at the IBGE Foundation and manager of the Brazilian Geospatial Data Directory (“Diretório Brasileiro de Dados Geoespaciais, DBDG) of the Brazilian National Spatial Data Infrastructure (“Infraestrutura Nacional de Dados Geoespaciais”, INDE).
🎥 Watch on IVIDES.org’s YouTube channel.
Rogério talked to us about the importance of open data and how the collaborative mapping can helps Brazil in the production of official cartographic data. The interview was conducted by Dr. Raquel Dezidério Souto and all details can be found at:

As part of my commitment to OpenStreetMap-NextGen migration, I undertook a comprehensive security review of the existing OpenStreetMap website. I followed the principles of coordinated vulnerability disclosure, working directly with the maintainers to responsibly report my findings. Today, I’m making the details of this process public and verifying the status of the fixes.
Authorization tokens (oauth, session, user tokens) are stored in plain text. Read access to the database allows full impersonation of any user.
Status as of 2024-03-15: Partially vulnerable (oauth still depends on plain text storage)
NextGen Codebase Status: Fixed (all authorization tokens and credentials are hashed or encrypted for secure storage)
The tokens used to ensure the authenticity of email replies are too short (24-bit), making them susceptible to brute-force attacks. An attacker could potentially guess the token and impersonate a legitimate user in email conversations. This vulnerability is especially dangerous if the attacker already has access to a conversation’s metadata (allowing for complete security bypass).
Status as of 2024-03-15: Fixed (now with 48-bit security)
NextGen Codebase Status: Fixed (128 or 256-bit security; undecided)
Apparently, OSM in Vietnam is in a very poor condition. And one of the reasons would be the absence of several nature reserve areas, even compared to the two neighboring Indochinese brothers, Laos and Cambodia. Despite the fact that the Department of Forestry has published a document stating that there are 34 national parks and 56 nature reserves, until now (15 March) only half of them have been mapped to OSM.
Here’s the list:
Official “Nature Reserve” title refers to the fact that these areas have their own management board (ban quản lý) and is usually a division of the provincial departments of agriculture and rural development (Sở Nông nghiệp và Phát triển Nông thôn). These includes:
we present the Mapeia Belém project to the Brazilian openstreetmap community, which is an initiative of UMBRAOSM União dos Mapeadores Brasileiros do Openstreetmap and partners such as Meninas da GEO, Capitulos Youthmappers and other groups and in addition to the Brazilian Openstreetmap community and aims to update data in city of Belém for the Major Events that the city will host in 2024 and 2025 such as FOSS4G and COP 30.
The key “name” is one of the 10 most frequently used characteristics of objects - according to Taginfo 100 million times. It is probably also the tag with the most errors. A random sample in my neighbourhood showed an error rate of 8.4% (N=1092). Possible reasons:
The proposal relates to point 2, possible misunderstandings regarding the meaning of the “name” tag.
The main article names lists 14 different keys of the proper name, differentiates them from each other and from non-proper names and gives many examples. The article is quite extensive with 29k characters.
Of the 14 keys, 5 keys do not have their own wiki page: int_name, loc_name, nat_name, reg_name and nickname.
The article on the key name is similar to the main article names, only somewhat shorter. It is still quite extensive with 18k characters. All other articles are short.
Readability.
The text is very extensive and therefore requires perseverance. However, it deals with all aspects of name keys in detail and consistently. Many examples illustrate the basic idea.
Readability, redundancy, clarity.
The text for the key name is very long at 18k characters, the essentials are lost in the sea of words. Much of it is a repetition of information that is already available elsewhere:
In addition to the high redundancy, the text is also blurred. The core - the proper name - is not mentioned at all. The explanations lead to problematic statements.
For all that have been eagerly awaiting this to happen, there is more good news, however!
The OpenStreetMap Foundation had quite recently launched a worldwide membership campaign with the objective of growing and diversifying OSMF membership in regions where there are very low or no OSMF members. And I am proud to say that I was/am part of this campaign. I should say that it is also my very first time volunteering for the OpenStreetMap Foundation and the experience has been & continues to be very enriching to say the least. In late January, I had responded to a call for volunteers & campaigners to help grow OSMF membership on Slack & since then, I’ve been part of a very diverse, talented & committed group of campaigners & volunteers.
On the first few virtual meet-ups via Google meet, I had promptly signed up for the visual comms/mapmakers role as I believed I could use whatever little designing skills & experiences I had to aid in creating & designing comms material for the campaign. In doing so, I had been thrown into a mix of incredible volunteers from around the world. Our work as visual comms/mapmakers volunteers had revolved around creating posters, pubmats, infographics, maps, etc. and these materials feature a lot about the OpenStreetMap Foundation, testimonials, how to join, membership types, why join, etc. However, generating these materials wasn’t an easy feat as the process often involved planning, a lot of discussions, facilitating, reviewing, and amending the materials as per suggestions/recommendations from the OSMF Board.
I believe that this volunteering opportunity has helped me grow in ways I wouldn’t have imagined because in the short period of only two months, I have learnt a lot about community, having being part of a group with shared or common interest but also acknowledging the different ideas, strengths & capabilities that each one of us had & brought to the table allowed us to effectively work together to bring about the outputs we were tasked to deliver.
A recent discussion on the osm-gb IRC channel was about how to map chapels within crematorium buildings.
I thought it was worth summarising some of that discussion. These notes pertain to crematoria in England and Wales. I have attended a funeral at that in Geneva, but that was twenty years ago.
One of the difficulties is that most visits to a crematorium are likely to be to attend a funeral service. This is not conducive to any kind of sophisticated micromanaging, but does allow a decent amount of basic observation. In addition I’m not aware of well-developed tagging standards for various features, as may become apparent by looking at some of my examples
Hello Community,
Recently, I embarked on a quest to explore second-hand stores and made an intriguing discovery—not only about the variety of hidden treasures but also about the limitations of the existing data in OpenStreetMap.
At the beginning of my search i obviously used OSM to look for second hand shops. I used https://openstreetbrowser.org/ and created a custom category with the code
query:
13: nwr[shop=second_hand]
and discovered that there are just few second-hand stores mapped in my area. I was sure that this is not possible and so i searched the internet to create my own list while cross-referencing various websites, blogs and platforms.
To optimize my exploration, I looked to create an efficient route—the classic Traveling Salesman Problem. There are various tools and APIs that can be utilized for this purpose. After some deliberation, I opted for Routexl, which best suited my needs as its possible to use it for free if you don’t have more than 20 points.
Armed with the list and the route, I got out with my bicycle on two separate days to visit most of the second-hand stores and map them. But my journey didn’t end there. I checked again with the OpenStreetBrowser and and shared it the first time within a local community. The community then showed me another second-hand store specializing in computers—an aspect I had not previously considered, as my focus was on clothing stores.
Now there are two already mapped stores where its not clear if they are still in operation. More research and exploration is required to keep everything recent.
It was interesting to discover how these store did not get mapped previously or did not get any attention even after they got added to OSM. It was a nice experience to find something that might be needed locally.
Lets fill the map with new discoveries!
Open street mapping training was started at. 09:00, it was located at Kacyiru in Gift house where headquarter of OpenStreetMap Rwanda located. it was started by Jeannette as coordinator of Eco mappers, she starts with welcoming all newcomers (the trainee of the day) with good greeting and asked them to feel at home. as continuing she asked Jack to explain for us what OpenStreetMapping mean? what Eco mapper do? he told us where Eco mapper comes from, their vision and missions etc. jeanette continue as the newcomer to present itself and then she shows us her team one by one in his/her name and what he/she responsible for in Eco mappers group. continuing with receiving speakers, our special guest etc. also, we taking tea break together, then we follow another speaker. as we continuing to be celebrating women day, we play game together, and then we start to study how can we contribute to mapping process, Liliane helper us and another ecomappers member then we start to map, where the first mapper of the day mapped 170 buildings, he is a boy, finally, we took photos and sharing food together.
