When linking to an image via the mapillary= key typically the link is just to an image id e.g. the full image.

With 360° imagery its getting difficult. Are you referring to the right or the left side of the road? So a street lamp may be ambigous.

In the panoramax key discussion page there was the idea to also use x/y and zoom as additional parameters to have the correct rotation and zoom in the link aswell.

So i quickly tried and it works - at least in josm.

iD does not offer a link anymore in the Fields as it seems it does some url key value validation, and when its not numerical it simply does not produce a link. A wise security decision, but needs some love.

Also the mapillary josm plugin does not offer to set a link with x/y and zoom so for now its a manual task.

So just the ball rolling i opened issues:

• josm mapillary plugin to set x/y and zoom for 360° imagery Josm/Mapillary/issues/244
• iD editor for showing a link with additional parameters Openstreetmap/iD/issues/10951

The very same issue of course applies to panoramax image uuids aswell.

Made in Tanzania, serving Global

March 2025 wasn’t just the end of a cohort—it marked the beginning of a movement.

At the Better Tomorrow Program Cohort 1 Closing Ceremony hosted by ROOTGIS, we saw young innovators pitch projects that tackled everything from waste management to housing access. But one powerful element tied these innovations together—geospatial intelligence powered by open data. And more specifically: OpenStreetMap.

🗺️ Why OpenStreetMap Matters

OpenStreetMap (OSM) is more than a map—it’s a platform. A canvas. A growing, living dataset built by volunteers and available to everyone. In a country like Tanzania, where commercial mapping tools are often inaccessible or outdated, OSM becomes a critical tool for innovation.

ROOTGIS has long been a champion of OSM, training youth and women in mapping, storytelling, and community data collection. This digital foundation made it possible for the young minds in this cohort to think spatially, act locally, and build globally relevant solutions.

Let’s break it down—team by team—to see how OSM played a role.

♻️ EcoCycle Tanzania (Team: Neon Nexius)

Turning organic waste into fertilizer and animal feed.

OSM relevance: Their approach requires identifying areas with large volumes of organic waste—markets, residential zones, and farming clusters. By overlaying OSM data layers like land use, landfills, markets, and transport routes, they can optimize where to collect and distribute products.

🏡 Nyumba Nyumbani (Team: Learning Hub)

Helping visitors and locals find homes before or after arriving in the country.

OSM relevance: This innovation is inherently map-based. Using OSM as the basemap, they can geotag apartments, neighborhoods, landmarks, and points of interest. It’s a true example of how open mapping can unlock trust and transparency in housing—a critical issue for urban newcomers.

🚛 Intelligent Cargo Optimization System (ICOS) (Team: Innovation Hub)

Matching delivery trucks with return cargo to cut transportation costs.

OSM relevance: This project depends on road networks, routing, and logistic corridors. OSM’s detailed mapping of Tanzanian roads—even in rural areas—helps them model routes, calculate optimal paths, and identify bottlenecks. OSM + logistics = efficiency.

🧱 Plastic Waste to Tiles (Team: Jenga Link)

Recycling plastic waste into construction tiles.

OSM relevance: To collect plastic waste effectively, they need spatial data on residential density, waste hotspots, and informal dumping grounds. Using OSM’s building footprints and land use tags, they can plan smarter collection routes and identify high-waste areas for community engagement.

🔥 Eco-Bamboo Charcoal (Team: Creators)

A sustainable energy solution replacing wood charcoal with bamboo briquettes.

OSM relevance: Mapping deforested areas, biomass-rich zones, and charcoal distribution points through OSM helps the team understand environmental impact and optimize production sites. They can also use satellite + OSM overlays to track and validate bamboo availability.

💡 A Foundation Built on Open Data

Every one of these teams used data as fuel—not just passion. And it’s data from the community, for the community.

ROOTGIS, as a regional leader in open mapping, made this possible by:

• Training youth in OSM data collection using smartphones and field apps like ODK, OSMAnd, and KoboToolbox.
• Encouraging innovators to treat geographic information as infrastructure, not just as a background layer.
• Hosting Mapathons and digital literacy camps to build a mapping culture across Tanzania.

🏆 Spotlight on the Winners

Two teams stood out and won development support:

• 🥇 Innovation Hub with ICOS: For tackling transportation inefficiencies.
• 🥈 Learning Hub with Nyumba Nyumbani: For creating a real-time housing discovery solution.

Their success isn’t just technical—it’s spatial. It’s a testament to what happens when young minds have access to the right data and the right mindset.

🔄 A Call to the OSM Community

To my fellow mappers: your edits matter more than you know. That footpath you traced? It might become a delivery route. That school you added? A reference point in someone’s housing search. That garbage dump you mapped? A launchpad for waste recycling innovation.

We often say that maps change lives. In Tanzania, we’re now watching that happen in real-time.

Let’s keep mapping. Let’s keep empowering. Let’s build a better tomorrow, one node at a time.

Posted by a mapper who believes innovation grows best when it’s rooted in open data.

Leaving my country, Nigeria, to attend the 2024 SOTM conference at the University of Nairobi, Kenya was a thrilling and enlightening experience for me. The whole event immersed me in the dynamic world of open mapping. The conference brought together various groups of professionals in the field of open mapping and it was great to finally see them in person. Most importantly, I was able to reconnect with YouthMappers Regional Ambassadors, fellow YouthMappers from Africa, Asia, America and wonderful OSM contributors from the globe.

It was an ideal opportunity for me to participate in insightful discussions and interactive workshops, all focused on utilizing OSM for advanced evaluations and humanitarian initiatives. Networking with fellow mappers allowed me to exchange ideas that deepened my understanding of the innovative technologies being employed to improve mapping efforts across the world. I participated in talk sessions that highlighted how empowering local communities to contribute their knowledge can significantly improve the accuracy and relevance of mapping data, ultimately leading to more effective solutions for regional challenges. I was particularly interested in these talks highlighted below:

Openrouteservice version 8- Experiences and insights from 10+ years of running and providing a global OSM driven, free and open-source routing engine by Julian Psotta , Sustainable Transport on the Map by Taylor Reich, Generating Ways with the Strava Heatmap by Derick Yang, Cloud-native OSM for Visualization & Analysis by Wille Marcel

I was delighted to volunteer as a session host for the Amboseli room where I facilitated workshops like;

• Mapping with every door by Ilja Zverev
• Hands-on data validation on OSM: Best practices and tools by Michael

On the final day, I gave a lightning talk on CampusGuide, a tool aimed at improving campus navigation using updated maps on OSM. Exploring the city was an exciting moment for me and also attending social events was a great way to connect with other mappers, share experiences, and build lasting friendships within the global OpenStreetMap community.

As I prepared to leave Kenya for Nigeria, I was overwhelmed by a flood of emotions because I knew I was going to miss the city, experiences and friends I have made during my stay. Though my stay was brief, the impact the whole event had on me is lasting and unforgettable. All thanks to HUMANITARIAN OPENSTREETMAP TEAM (HOT) for making my participation a reality through the OPEN SUMMIT TRAVEL SUPPORT GRANT. I really look forward to the next annual conference which is going to take place in the Philippines.

Binnenkort gaat onze pop up koffiebar weer open. Dan kan je een lekkere kop koffie of een heerlijke homemade lemonade komen drinken, of je kan hem gewoon meenemen (take away dus).

Zet alvast donderdag 29 mei in je agenda, dan openen we onze koffiebar, later meer info over de tijdstippen.

Les bornes de servitude militaire des bornes deployees autours des forts et place militaires au 19eme siècle. Elles délimitaient trois zones autours des terrains militaires dans lesquels il était interdit de construire ou planter. Certaines de ces bornes peuvent encore être trouvées dans la nature. Elle ne doivent pas être confondues avec les bornes de propriete qui délimitent les frontières de terrain militaire et qui sont octogonales et non carres comme les bornes de servitudes.

Note: Dans cet article, je donne ma version de la cartographie de ces bornes. Je n’ai pas trouve beaucoup d’informations sur la manière de cartographier des bornes alors j’ai bricole un ensemble de tags que je trouve cohérents.

Comment cartographier

Sur un node specifique pour cette borne, on ajoute les tags suiavnts:

• historic=boundary_stone
• inscription=*
• format=squared_stone

Je me base principalement sur la cartographie des bornes de fontieres.

Kirtlington is not very well mapped Nor is weston on green business park - depends how much detail, e.g. compare to iSlip

Today we released version 2.1.0, a bugfix and maintenance release. The main visible change is that osm2pgsql now works better together with connection poolers and similar database middleware: prepared statements now use protocol level prepare instead of PREPARE SQL commands and there is a new option to explicitly create a primary key on flex tables.

Other fixes and features:

• check flat node file format for forwards compatibility to prepare for future changes of the flatnode file format
• fix two-stage processing when flat node file is used
• fix getting node locations in slim node with two-stage processing
• updated included libosmium, protozero and fmt libraries

Você já parou pra pensar no que essa imagem representa na vida de quem tenta encontrar um endereço e não consegue?

Você já parou pra pensar no que essa imagem representa na vida de quem tenta encontrar um endereço e não consegue?

Pra quem mora em um bairro onde a rua sequer tem nome no mapa? 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.

Dignidade é poder dizer onde você mora. É receber suas compras online.

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.

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.

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.

Juntos, podemos construir um mapa mais justo, mais completo e mais humano.

筆者は、この表示の存在を当たり前のものと認識していたのだが、実際は日本固有のものらしい。
設置は航空法施行規則第79条十七（e-Gov）に定められており、日本国内のほぼすべての空港にあるようです。この規定について、上位存在となる国際条約などは確認できませんでした。また、AIPドキュメントでも当該表示について言及を確認できませんでした。

タグ利用による地物の明示

aeroway=navigationaid
navigationaid=id
inscription=(実際の表示文字列)
colour=(文字色)

この組み合わせでのエリアタグ付けとしました。 navigationaidがVisual航行向け支援の要素が強いということ、
AIPドキュメントで id = 識別・標識 という訳語が充てられていること、
から決定しました。

Mapping campaigns

• OpenStreetMap Ireland has successfully completed its Louth mapping task, which was launched on 12 November 2024. The project, finished in just three months, was made possible by the contributions of Anne-Karoline Distel, jonnymccullagh, Jonako, Ciarán Staunton, and snoozingnewt. During the mapping process, three previously unrecorded archaeological sites were identified and reported to the National Monuments Service, with two of them confirmed.
• OpenStreetMap India contributor Nilabrata was recently featured in a news article that highlighted their effort to map amenities in Siliguri through field surveys with their college.

Community

• ^[1] OpenCage interviewed Julien Minet, the developer behind OpenArdenneMap, a map style designed specifically for hiking in Belgium’s Ardennes region.
• In a bid to curb the growing issue of SEO-related spam, Allison P has launched a campaign targeting fraudulent edits in OpenStreetMap.
• Christopher Beddow highlighted the power of volunteered geographic information, such as OpenStreetMap, emphasising its decentralised nature. No individual can grasp the entire system, but each contribution helps build a more complete picture, as every observer brings a unique piece of knowledge toward assembling the whole, continuously shaping our understanding of the world.
• We reported earlier on the weekly presentation of the Japanese edition of weeklyOSM by our colleagues in Fukushima on YouTube. Gregory Marler, a long-time active OSMer, took up our suggestion for a visual and linguistic presentation in other languages and discussed issue #766 on YouTube, beautifully organised by category in English. Recommended for imitation.
• Jan Prazak argued that objects in private gardens that do not require building permits, such as small shelters and, in particular, movable items like round swimming pools, should not be included in a public map.
• Martijn van Exel has developed ‘Meet Your Mappers’, a website designed to generate a list of active mappers in any given local area.
• Rphyrin has authored a brief biography of Gunther W Holtorf, a German national and Lufthansa Airlines manager in Jakarta, who developed the city’s first modern map in 1977. Encouraged by his peers, who found his hand-drawn sketches invaluable for daily navigation, Gunther took on the project to create a more comprehensive and accurate map of Jakarta.
• se_bras recently took part ► in a community-led mapping campaign at the El Totoral Wetland, utilising ChatMap, a WhatsApp-based mapping tool developed by HOT.
• TonyJC commented on the newly released Esri World Imagery for Panama, noting that previously mapped features, such as buildings and roads, now appear significantly misaligned with the updated satellite imagery.

Local chapter news

• OpenStreetMap Austria announced in a blog post and on the OSM Community forum that the organisation has completely revised its website.
• The OpenStreetMap Indonesia community recently uncovered a case of a ‘trap street’ (a fictitious entry added to a map to catch unauthorised copies). This case involved German cartographer Gunther W Holtorf, who labelled a landfill in Bantargebang, Bekasi, Indonesia, as ‘Monte Klamot’. Holtorf later admitted that the name was a Berlin-specific joke related to landfill sites. The ruse worked. A well-known Indonesian cartographer was caught incorporating ‘Monte Klamot’ into their own map, unaware that the name was entirely fictional. A Bekasi-based OSM Indonesia community member confirmed that no such place exists in Bantargebang, reinforcing that the entry was a deliberate trap to expose plagiarism.

Events

• The material from the ‘OpenStreetMap Training Course’, maintained ► by the IVIDES.org Institute, will be used in the face-to-face training that will be offered ► to participants of the Latin American Free Software Festival – FliSol Resende 2025, to be held in person on Saturday 26 April. You can still register ► and take part in this event. The IVIDES.org thanked the organisers for including OpenStreetMap on the agenda.
• Christoph Hormann (1) and GeoObserver (2 ►) have shared their insights from the FOSSGIS 2025 Conference.

Education

• You can now access the full training guide for tree field mapping with OpenStreetMap (in Portuguese) that was offered ► at the Green Open Data Day 2025, Rio de Janeiro, Brazil. The video of the live session with the speakers and other files are available on Wikimedia Commons. The organisers would like to thank their partners and sponsors for their collaboration in this event.
• Teachers at the initial, primary, and secondary levels of GAL School ►, Cusco Peru, have begun training to integrate mapping tools into classes. Together with their students, they will explore these tools in greater depth through the HOT Learning Centre platform.

OSM research

• Otakar Čerba has published a study introducing a methodology for assessing territorial innovation potential using OpenStreetMap data and geoinformation technologies. This research highlighted that OSM-based assessments offer spatially detailed, flexible, and replicable insights into regional innovation potential. However, the study also acknowledges the challenges of crowdsourced data, including variability in quality and completeness.

Humanitarian OSM

• The Argentine newsletter NewsData talked ► with Juan Arellano, from HOT, about the importance of collaborative mapping in disasters, in relation to the floods in Bahía Blanca and the subsequent mapping campaign, emphasising the importance of coordinated work with local authorities so that the data produced can be used.

OSM in action

• One of the biggest Italian online map providers has switched ► to OSM as its main data source.
• The Trufi Association has been recognised in a recent case study by the Open Source Observatory and Repository (OSOR), a platform that celebrates the impact and potential of Free and Open Source Software in public administration and beyond. OSOR’s mission is to promote the use of open-source software, and Trufi naturally align with their values, particularly in the realm of urban mobility.
• Stadlholz, an online marketplace for wood products and related services, is utilising OpenStreetMap data to display listings by region.

Software

• Mapy.cz has officially been rebranded to Mapy.com, citing the need for a more globally recognisable name.
• In response to GitHub’s decision to archive its repository over an alleged connection to a US-sanctioned region (we reported earlier), the Organic Maps team has migrated its development repository to a self-hosted Forgejo instance.
• Gregory Marler compared plugins that integrate OpenStreetMap into WordPress sites and enable geotagging of posts, demonstrating the MiKa’s OSM plugin and highlighting its advantages over directly embedding map JavaScript into content.

Programming

• Kumakyoo provided a technical breakdown of their OMA file format, a newly introduced format for storing OpenStreetMap data.
• As his contribution to last year’s iteration of the pen plotter postcard exchange (#ptpx), Noah Doersing has built a small web-based tool that extracts road data from OSM, then converts it to a colour-coded SVG file ready for drawing on an AxiDraw pen plotter.

Releases

• The GeoDesk team have released Version 1.0 of their OpenStreetMap toolkits for Python and Java, and outlined the upcoming capabilities expected in Version 2.0 (most notably support for fast incremental updates using minutely change files).
• Geotoko has released the latest version (25 March 2025) of their PostGIS dump of the OpenStreetMap database for the Netherlands and neighbouring regions.

Did you know that …

• … the France 3 (Grenoble) channel published a report in October 2007 on the OpenStreetMap project, in which Raphaël Jacquot showed how he mapped city streets in the field with a notebook and a GPX trace? The video recording is available on Framatube.
• … weeklyOSM is written with the help of OSMBC? Created by TheFive, this specialised tool simplifies the editorial process, allowing editors to efficiently gather news references and later refine them using Markdown and translate into various languages.
• … there is a script that allows you to copy OSM data to the OSM sandbox?

Other “geo” things

• A satirical campaign and petition to crowdfund the purchase of California on behalf of Denmark has launched, widely seen as a response to President Donald Trump’s proposal to acquire Greenland. Though humorous in tone, the movement, which has amassed hundreds of thousands of signatures and global media coverage, is seen as a critique of US foreign policy and territorial ambitions.
• Are you developing digital services, simulation models or thematic digital twins? Are you a player in the fields of management, energy, transport or insurance? Then this IGN (France) initiative ► may be of interest.
• The IHO has a crowdsourced initiative to improve the collection, quality and availability of hydrographic data worldwide, which has resulted in the creation of the Crowdsourced Bathymetry Working Group. The IHO has been responsible for maintaining the GEBCO (General Bathymetric Chart of the Oceans) over the past 10 years, and they have been collecting data from ships and other vessels to improve the global chart by 2030.
• Lormaccone demonstrated how to use a Kindle eBook device as a high-contrast GNSS display in a 2017 article.
• Maxar Intelligence, a subsidiary of the US space technology firm Maxar Technologies, has developed ‘Raptor’, a visual navigation system designed to function without GNSS. It converts satellite images into 3D data, enabling drones to compare real-time camera footage with terrain models to determine their exact position and orientation. Primarily developed for military drones, the system enables operations in environments where navigation satellite signals may be compromised.
• The 2GIS company talked about their experience launching a crowdsourcing Telegram bot for collecting photos of POI.

Ich habe versucht den Möhnetalradweg einzutragen: osm.org/relation/18945126 und dann festgestellt, daß jemand anders das an anderen Stellen auch schon begonnen hat: osm.org/relation/12548746 Wie fügt man das Ganze zu einer einzigen Relation zusammen, ohne daß alles einzeln als Handarbeit erledigt wird?

On the 28 of March, I just discovered that our Village is not well represented in the wikipedia map, as well as the article about our community on wikipedia is not comprehensive, as i was researching further about my local community online.

That was the beginning of my journey on openstreetmap, as I’ve decided to become a contributor to help improve the visibility of our community on the world map.

Though I’m starting as a novice as at today been the 4th of April, 2025, I’m determined to walk myself through the process of learning how to edit on open street map. As I’ve started on a self learning steps, I look forward to maybe joining a community of mappers, finding someone as a guide and becoming a full member of openstreetmap community.

We want to notify OpenStreetMap Foundation members about an important recent change in the renewal process for memberships set to be automatically renewed via PayPal, and how it may affect you.

If you had enabled the automatic renewal of your membership via PayPal, you must have received an email from PayPal stating: “We stop all recurring payments of all members to prevent inadvertent double payment”. We confirm that, for the time being, OSM Foundation members will need to renew their membership manually.

Reason for the change

The Membership Working Group 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.

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.

Manual renewal process

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.

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.

Alternatively, you can renew via https://supporting.openstreetmap.org/#Membership-Categories. Please ensure that you:

• Select the correct membership type.
• Fill the email address associated with your OSM Foundation membership, if you have multiple email addresses.
• Have the OpenStreetMap user name ready that shall fulfill the baseline activity requirement . If you have an Active Contributor Membership with your membership fee waived via mapping contributions (so you are not affected by this issue with auto-renewals), you still need to have at least 42 mapping days in the past 365 days at the time of your membership renewal.

To ensure that your membership remains active, we strongly advise you to:

• Add a reminder about your need to renew the membership to your personal calendar, and
• Check that you receive a confirmation email after manually renewing.

Questions about your membership?

If you have questions about your membership, please email us at [email protected], from the email address associated with the membership. Please note that we are just a few volunteers, dedicating our free personal time to Foundation issues, so there might be some delay in the replies.

We need your help

Additionally, we are looking for volunteers to help with various tasks, including managing issues with membership renewals. You can read more information about what we do here. If you are interested in volunteering your time, please let us know at [email protected] with subject “Helping the Membership Working Group”. Your support would be greatly appreciated.

Thank you for your continued support to OpenStreetMap and for your membership.

Best regards,

Michael Spreng,
Membership Working Group Volunteer

This blog post is part of a series of blog posts about the new OSM file format “OMA”. This is the fifth post. At the end of the article you’ll find links to the other blog entries.

When relations where introduced (in 2008, if I remember correctly) I was a big fan of them. 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.

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.

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.

Multipolygons

Instead, I’m going to take a closer look at what is currently done with relations. According to taginfo, 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.

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.

Restrictions

Coming back to taginfo, the second place are restrictions. They make up about 16% of all relations. Typically, restrictions contain two ways (called from and to) connected by one or more elements (called via). Restrictions tell users whether or not they can continue their journey in a particular direction.

After thinking for a long time about how to fit them into Oma files, I realised, that the from and to ways are not completely needed. Only the last segment of the from element is used and only the first segment of the to 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.¹

Routes

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.

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.

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.² 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.

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.

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.

Boundaries

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.

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.

Public Transport, Destination Signs and other Relations

There are two other types of relations left: public_transport and destination_sign. 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.

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.

I didn’t look more closely at the other relations. They are not used much anyway. The converter converts them to collections.
