Pra quem chama um Uber ou 99 e o motorista não encontra o local? Ou pra um estudante que precisa fazer um trabalho de faculdade, mas as ruas da sua comunidade nem aparecem direito no mapa? Isso tem um nome: dignidade.</p> <p>Dignidade é poder dizer onde você mora. É receber suas compras online.</p> <p>É chamar um carro de aplicativo sem preocupação. É poder passar seu endereço pra um amigo, pra um parente, pra um vizinho. As prefeituras, o governo estadual e federal deveriam olhar com mais seriedade para o registro de ruas, bairros, vilas e distritos. Se isso fosse feito de forma justa e abrangente, o Brasil não seria esse imenso vazio cartográfico, onde tantas ruas seguem sem nome.</p> <p>Felizmente, estamos aqui pra mudar isso. Estamos mapeando ruas, bairros, vilas e distritos no OpenStreetMap, com o objetivo de dar nome ao que existe — e dar dignidade a quem vive nesses lugares.</p> <p>Porque todo mundo merece dignidade. Fica aqui o meu pedido: que todos os órgãos públicos e empresas que possam colaborar com esse projeto de mapeamento colaborativo se unam a nós.</p> <p>Juntos, podemos construir um mapa mais justo, mais completo e mais humano.</p> <p>hashtag#Vem se juntar a nós, entre em contato conosco!

We confirm that, for the time being, OSM Foundation members will need to renew their membership manually.</p> <h2 class="wp-block-heading"><a></a>Reason for the change</h2> <p>The <a href="https://osmfoundation.org/wiki/Membership_Working_Group" target="_blank" rel="noreferrer noopener">Membership Working Group</a> has decided to stop automatic email renewals via PayPal for all members for now. This decision was made because many payments do not register automatically, leading to incorrect reminder emails that confuse and annoy members and can result in double payments. Over the past two years, we have been unable to resolve this issue, and managing problems with automatic renewals requires significant volunteer time, which we currently lack. <br /><br />While automatic renewals offer convenience and ensure that your membership remains active without any interruption, given the current challenges, we have had to disable this feature.</p> <h2 class="wp-block-heading">Manual renewal process</h2> <p>Until we find a proper solution, all membership renewals will need to be done manually. We understand that this may cause some inconvenience, and we appreciate your understanding. We have set up an automatic reminder system and you will likely receive automatic email reminders before your membership is due to end.</p> <p>The automatic reminder emails sent four and two weeks before your membership ends, will contain a link which you can use to renew. You will also get additional reminders if you let your membership lapse, spaced out over several months.</p> <p>Alternatively, you can renew via <a href="https://supporting.openstreetmap.org/#Membership-Categories" target="_blank" rel="noreferrer noopener">https://supporting.openstreetmap.org/#Membership-Categories</a>.

They sounded great and promising. Meanwhile I think, it was a mistake to add relations, and if I where to decide I would probably remove them from OSM and replace them with something better.</p> <p>Let’s have a closer look: Nodes and ways (and areas) are simple: A geometry with some properties. Relations do not share this simplicity. They share the properties, but they do not have their own geometry. Instead, they contain references to some elements. This makes things complicated.</p> <p>I could write several articles about relations and why I think they are a bad idea, but this article is about relations in Oma files, so I’ll leave it at that for now.</p> <p> </p> <h3 id="multipolygons">Multipolygons</h3> <p>Instead, I’m going to take a closer look at what is currently done with relations. According to <a href="https://taginfo.openstreetmap.org/relations" rel="nofollow noopener noreferrer">taginfo</a>, more than half of all relations are multipolygons, that is, a collection of areas. Since we’ve already got areas in Oma files, this is easy to handle: All multipolygons are converted to one or more areas.</p> <p><img src="https://github.com/kumakyoo42/osmblog/blob/main/Oma/mp.png?raw=true" alt="multipolygons are converted to areas" loading="lazy"></p> <p>You may be wondering why I didn’t add a multipolygon (or multiarea) data type. Well, in the case of nodes and ways, OSM does not have a multi variant. So I do not see why we should treat areas differently. (Please note that areas in Oma files can contain holes, while in OSM the ways that form areas cannot.) All in all: For me it is much more straight forward to omit multi-variations everywhere.</p> <p> </p> <h3 id="restrictions">Restrictions</h3> <p>Coming back to taginfo, the second place are restrictions. They make up about 16% of all relations. Typically, restrictions contain two ways (called <code>from</code> and <code>to</code>) connected by one or more elements (called <code>via</code>). Restrictions tell users whether or not they can continue their journey in a particular direction.</p> <p>After thinking for a long time about how to fit them into Oma files, I realised, that the <code>from</code> and <code>to</code> ways are not completely needed. Only the last segment of the <code>from</code> element is used and only the first segment of the <code>to</code> element is used. Once I realised this, it’s obvious, that restrictions are just ways, with the first and last segments playing a special role. And so I decided to convert restrictions to ways.<sup id="fnref:1"><a href="#fn:1" rel="nofollow noopener noreferrer">1</a></sup></p> <p><img src="https://github.com/kumakyoo42/osmblog/blob/main/Oma/restrictions.png?raw=true" alt="restrictions are converted to ways" loading="lazy"></p> <p> </p> <h3 id="routes">Routes</h3> <p>Next on the taginfo list are routes. They are difficult to convert, and for a long time I didn’t know what to do with them. Unlike multipolygons and restrictions, they are not just a geometric replacement for another type: In the case of routes, the tags of the members can be important. In other words: They are real reference types.</p> <p>Until now, the Oma file format was a reference-free format. I reluctantly accepted that I had to add some references here. In OSM files the references point from the relation to the members. This is problematic in Oma files, because some elements have been split, so the IDs wouldn’t be unique any more. And anyway, IDs were not needed at all up to here.</p> <p>So I turned the references around: For this type of relation, they now point from the members to the relation, or collection as I call it in Oma files.<sup id="fnref:2"><a href="#fn:2" rel="nofollow noopener noreferrer">2</a></sup> This is better, because now only the collections need to have an id. This saves space and the ugliness is at the place, where the ugly elements are.</p> <p><img src="https://github.com/kumakyoo42/osmblog/blob/main/Oma/routes.png?raw=true" alt="routes are converted to a collection of backward references" loading="lazy"></p> <p>The drawback of this approach is obvious: when you’ve got a collection, you do not know the location of the members, so you need to search the whole file for them. To avoid this, I have added a slice description list to each collection. This list tells you, which slices contain the members of the collection and thus can speed up the search.</p> <p>Development of this part is still ongoing. The current implementation of the converter does not compute this list, and so searching the whole file cannot be avoided at the moment. The problem is that calculating these lists is not easy and probably needs a fourth step in the converter. I hope to find the time to implement this in the near future.</p> <p> </p> <h3 id="boundaries">Boundaries</h3> <p>On with the show: Next are the boundaries in taginfo. Boundaries are almost the same as multipolygons. The only difference is a few small additional elements, in most cases just the admin centre.</p> <p>Once collections are set up, the solution here is simple: Convert all members that resemble multipolygons to areas and make a collection of them and all other elements.</p> <p><img src="https://github.com/kumakyoo42/osmblog/blob/main/Oma/boundaries.png?raw=true" alt="boundaries are converted to a mix of a collection and areas" loading="lazy"></p> <p> </p> <h3 id="public-transport-destination-signs-and-other-relations">Public Transport, Destination Signs and other Relations</h3> <p>There are two other types of relations left: <code>public_transport</code> and <code>destination_sign</code>. Public transport relations are quite new, and if I were to predict the future, I’d say they’re going to cause some trouble. However they are here and I have decided to treat them similar to routes as a collection.</p> <p>Destination signs, on the other hand, are quite similar to restrictions, except that they can contain the location of the sign. So I created some ways from the restriction like members and made a collection out of them together with the sign position.</p> <p>I didn’t look more closely at the other relations. They are not used much anyway. The converter converts them to collections.</p> <h3 id="see-also">See also</h3> <ul> <li><a href="https://www.openstreetmap.org/user/kumakyoo/diary/406287" rel="nofollow noopener noreferrer">A New File Format for OSM Data</a></li> <li><a href="https://www.openstreetmap.org/user/kumakyoo/diary/406340" rel="nofollow noopener noreferrer">Using the Oma Library</a></li> <li><a href="https://www.openstreetmap.org/user/kumakyoo/diary/406393" rel="nofollow noopener noreferrer">Getting Files in OMA File Format</a></li> <li><a href="https://www.openstreetmap.org/user/kumakyoo/diary/406438" rel="nofollow noopener noreferrer">The OMA File Format</a></li> </ul> <hr> <ol> <li id="fn:1"> <p>It’s possible for restrictions to contain more than one <code>from</code> or <code>to</code> ways.

Die Schüler:innen, ihr Lehrer sowie der Schulleiter hatten die vielleicht weiteste Anreise aus dem deutschsprachigen Raum zur Konferenz auf sich genommen. In Ihrem Vortrag stellten sie ihr Projekt der Zusammenarbeit zwischen Schule und Kommunen vor. Umgesetzt wurde das Projekt mit PostgreSQL und QGiS im Rahmen des jährlichen Vermessungspraktikums eines technischen Gymnsiums in Südtirol. Dieses schöne Beispiel für den Einsatz von FOSSGIS in Schule und Ausbildung will andere Schulen ermutigen, diesem Beispiel zu folgen. Insbesondere das Feedback der Schüler:innen zu ihrem Praxisprojekt zeigt eindringlich den Mehrwert und empfiehlt es zur unbedingten Nachahmung.</p> <p>Zum Ausklang der ersten drei Konferenztage lud der FOSSGIS e.V. zum Sektempfang ein.</p> <h3 id="rahmenprogramm">Rahmenprogramm</h3> <p>Das großartige Rahmenprogramm wurde gut angenommen. Es gab Exkursionen durch Münster, am Dienstag in Form eines geographischen Stadtrundgangs, am Freitag stand die Kartensammlung des Landesarchives NRW auf dem Plan und am Samstagnachmittag begaben sich die Teilnehmenden auf einen archäologisch, historischen Stadtrundgang.</p> <p>Das Treffen der GeoChicas am Dienstag vor der Konferenz war ein großer Erfolg. Über 20 Frauen waren dabei und kamen schnell ins Gespräch. Auch der inoffizielle Start zeigte wieder, dass viele schon am Vortrag der Konferenz die vernetzung und das Gespräch suchen.</p> <p> <img src="https://www.fossgis.de/news/images/2025-03-28_FOSSGIS2025_GeoChcias_inoffiziellerStart.png" width="1000" style="border: 1px solid #808080; border-radius: 3px;"/></a> <br> <em>FOSSGIS Konferenz 2025 Treffen GeoChicas und inoffizeller Start am Vortrag der Konferenz</em></p> <p>Die Abendveranstaltung mit mehr als 500 Teilnehmenden in der Mensa am Aasee war ein kulinarischer und geselliger Höhepunkt der Konferenz.</p> <p>Zum Auftakt des OSM Samstag gab es am Freitag ein Treffen im Hier und Jetzt am Ufer des Aasees.

The event showcased an impressive array of presentations and workshops, from mapping remote areas of the Amazon to using innovative tools and techniques for open mapping. I am so grateful to everyone who shared their work and insights, broadening my understanding of the challenges and opportunities in Latin America.</p> <p>As a Director of the OpenStreetMap Foundation (OSMF), I had the opportunity to present about the role of the OSMF, the purpose of the <a href="https://osmfoundation.org/wiki/Board_Member_Bios" target="_blank" rel="noreferrer noopener">Board of Directors</a>, and how we strive to support the global OSM community. Engaging directly with attendees highlighted how essential it is for the OSMF to maintain stronger connections with regional communities. I was surprised to learn that this was the first time an OSMF Board member had attended a SOTM LATAM. Representation matters, and I am committed to ensuring this is not the last time. Strengthening our communication channels with the LATAM community is vital, and I am eager to build more meaningful and consistent engagement.</p> <p><strong>Open Conversations with the Community</strong></p> <figure class="wp-block-image size-large"><a href="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150.jpg"><img decoding="async" width="1024" height="768" src="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-1024x768.jpg" alt="" class="wp-image-176661325" srcset="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-1024x768.jpg 1024w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-300x225.jpg 300w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-768x576.jpg 768w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-1536x1152.jpg 1536w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150-624x468.jpg 624w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3150.jpg 2016w" sizes="(max-width: 1024px) 100vw, 1024px" /></a></figure> <p>A key part of this experience was the opportunity to hear directly from participants. During the event, an open online collaborative document page was shared, allowing attendees to express their thoughts, feedback, and even grievances with the Board. Some of the valuable insights included:</p> <p><strong>Regional Representation on the Board</strong>: There were discussions around creating dedicated Board seats for representatives from different regions to ensure equitable representation, particularly for communities that may struggle to gain sufficient global votes.</p> <p><strong>Lack of Awareness of <a href="https://osmfoundation.org/wiki/Working_Groups" target="_blank" rel="noreferrer noopener">Working Groups</a></strong>: Many attendees expressed that they were unaware of the existence and functions of OSMF Working Groups. Promoting these groups and encouraging participation from Latin American communities could strengthen regional representation and collaboration.</p> <p><strong>First Formal Board Presence</strong>: For many, this was the first time they had the opportunity to hear directly from a Board member. The engagement was positively received, and it was clear that there is a desire for more consistent interaction between the OSMF and Latin American communities.</p> <p><strong>Recognizing Regional Entities</strong>: Some established and active communities in the region are not formally recognized as <a href="https://osmfoundation.org/wiki/Local_Chapters" target="_blank" rel="noreferrer noopener">official OSM chapters</a>. This can create challenges in accessing grants and participating in global events. Greater support from the OSMF could bridge this gap.</p> <p><strong>Building Strategic Partnerships</strong>: Participants highlighted the potential for OSMF to collaborate with independent media organizations in Latin America, especially within data journalism, indigenous journalism, and environmental reporting. Strengthening these connections could increase OSM visibility and promote responsible use of open geospatial data.</p> <p><strong>Funding for Training and Capacity Building</strong>: Accessing financial resources for training journalists and other community members on OSM tools was identified as a critical need. Expanding funding opportunities for local projects could accelerate mapping efforts and amplify the impact of OSM data.</p> <figure class="wp-block-image size-large"><a href="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1.jpg"><img loading="lazy" decoding="async" width="1024" height="768" src="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-1024x768.jpg" alt="" class="wp-image-176661352" srcset="https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-1024x768.jpg 1024w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-300x225.jpg 300w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-768x576.jpg 768w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-1536x1152.jpg 1536w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1-624x468.jpg 624w, https://blog.openstreetmap.org/wp-content/uploads/2025/04/IMG_3125-1.jpg 2016w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></a></figure> <p><strong>Moving Forward</strong></p> <p>The feedback shared during SOTM LATAM was invaluable. Meaningful participation and representation of all regions are essential for the growth and success of OpenStreetMap. We need to be more engaged with this and all communities. If you have any suggestions our communication channels (<a href="https://community.openstreetmap.org/c/osmf/41" target="_blank" rel="noreferrer noopener">1</a>;<a href="https://lists.openstreetmap.org/listinfo/talk" target="_blank" rel="noreferrer noopener">2</a>;<a href="https://lists.openstreetmap.org/listinfo/osmf-talk" target="_blank" rel="noreferrer noopener">3</a>;<a href="mailto:board@osmfoundation.org" target="_blank" rel="noreferrer noopener">4</a> ) are always open.</p> <p>To everyone I had the pleasure of meeting, thank you for your warm welcome and for sharing your perspectives. If you have further questions, comments, or feedback about the event or the OSMF, please feel free to reach out. ¡Obrigada, SOTM LATAM!</p> <p><strong>SOTM LATAM 2025</strong><br />I’d like to also share with you all that SOTM LATAM 2025 will be in Medellin, Colombia from September 4th-6th. This is a great opportunity for all to get to know this amazing OSM Community and learn about the inspiring work they are doing.</p> <p>Additionally, I’d like to ask our sponsors and contributors to consider becoming sponsors of this event. This is an amazing opportunity to become involved and support the Latin American Community.
