Český Krumlov stojí před rozhodnutím, které zdaleka není jen technické. Postavit severní obchvat, anebo hledat jiná řešení dopravní zátěže? Na první pohled jde o jasný krok. Odvést tranzit mimo město. Jenže realita krajiny, chráněných území a členitého terénu ukazuje, že nic takového nejde udělat bez následků. Severní svahy města přecházejí do CHKO Blanský les a přírodního parku Cvičák, kde každý zásah znamená dlouhodobou změnu charakteru krajiny. Městská varianta trasy zas počítá s tunelem, který by stavbu významně prodražil. Ani jedno ale nepovažuji za kvalitní odpověď k výzvě, co s dopravní situací.

Bank and ditch

Preliminary

This is a provisional report about a future proposition for specific tags for the following types of banks and ditches:

• bank and ditch barrier
• hedge and ditch barrier
• fossé bordier
• talus
• old way (e.g. Tiense Groef)

About bank and ditch



Bank and ditch or hedge and ditch are man made earthworks in the landscape. All have a historic interest as being the landmark for present and past administrative boundaries. They were used to limit lands, parish, communes, forests, etc.

I’m raising funds to purchase the historic 1:50,000 topographic map series of Eswatini (formerly Swaziland), so I can preserve and share them online as a seamless, zoomable mosaic - free for everyone.

In 2008 I successfully raised £1000 to acquire the equivalent series for Namibia (South West Africa). You can explore that project here: https://namibia-topo.openstreetmap.org.za/

Donate and more information: https://www.gofundme.com/f/purchase-historical-eswatini-topographic-maps

Inspirado pelas estatísticas disponíveis em OSMstats, compilei abaixo a lista de todos os países e territórios atualmente monitorados na plataforma.

Cada nome está vinculado à sua respectiva relação administrativa no OpenStreetMap. A lista dessa forma ajudou muito na tarefa de mapear em todos os países e territórios do OpenStreetmap, conforme relatei aqui.

Esta lista pode ser útil para consultas, análises ou scripts que envolvam os limites administrativos, permitindo acesso direto às relações correspondentes.

Vale aqui uma observação. Entre os 260 nomes apenas 216 correspondem ao admin_level=2, o que é considerado de facto o nível de país. Os outros valores que aparecem são admin_level=3 (17 locais), admin_level=4 (14 locais), admin_level=10 (2 locais) , e 11 locais não possuem a chave admin_level.

Saber onta

This is the story of how the cycling association measured streets in Bruges and got what they wanted - a cycling zone - 5 years after the initial campaign…

The setup

First some belgian road law. One of the peculariaties of Belgian is that we have the concept of a ‘cyclestreet’. This is a street where cars are not allowed to overtake cyclists - one of the tools to make cities more liveable. A cycle zone is similar, except that it is about multiple streets. It needs different traffic signs and is in effect until the “end of cycle zone”-traffic sign.

The cycling association of Bruges wanted a cycling zone in the entire city center. To force this, they devised a plan using a different law. The Belgian road code says that cars are not allowed to overtake a cyclist if the space between a cyclist and the car would be less then 1 meter.

In other words, if the cycling association could prove that most of the streets in Bruges are too small to legally overtake cyclists anyway, that would be a good starting point to force a cycle zone in the city. In practice, it would make the already existing situation more explicit.

Enter OpenStreetMap

As such, the local cyclist association asked me to help them in 2020, in the middle of the corona lockdowns.

I did create a custom version of StreetComplete to ask for the street width (a quest that StreetComplete would officially add about a year later).

And, as such, we got out into the city and, armed with a laser measurement device, took the width of every street in the historic center - a perfect activity to do during the corona lockdowns.

To display the information, I setup a custom map theme on MapComplete (which was quite young as well) to show the widths of the streets.

Using the measured width, parking and sidewalk information, MapComplete can automatically determine which streets are to small to officially overtake a cyclist.

Há algum tempo estabeleci para mim mesmo um desafio ousado: registrar pelo menos um changeset em cada país/região listada no OpenStreetMap. Eu me baseei na lista oficial do OSMstats, composta por 260 locais ao redor do mundo — e hoje posso dizer que o desafio foi concluído.

O mais interessante dessa jornada foi perceber como o mundo é diverso até no mapa. Em alguns locais, o mapeamento está tão detalhado que foi muito difícil encontrar algo para contribuir. Já em outros… praticamente tudo ainda precisa ser mapeado — sem falar na falta de imagens de boa qualidade para servir de referência.

No fim das contas, foi muito mais do que completar um checklist. Foi uma viagem virtual pelo planeta, enxergando paisagens mapeadas e não mapeadas, contrastes culturais e diferentes níveis de engajamento da comunidade.

E é exatamente isso que torna o OpenStreetMap tão especial. Cada contribuição, por menor que pareça, faz o mundo ficar um pouquinho mais visível.

Agora é pensar no próximo “desafio” 😄 28/10/2025

Solo tengo que escribir? Aparentemente si

When I was using JOSM tonight, the satellite imagery shown on my screen reminded me of something.

It reminded me of a simulation game I loved playing several years ago : SimCity 4.

Digitalni ortofoto Grada Karlovca 2023 na TMS i TM serveru

Zadnjih nekoliko objava se odnosili na DOF sniman dronom, za manja urbana područja. Prije smo objavili DOF sniman zrakoplovom za veća urbana područje poput Knin 2007, Zagreb 2012, Zagreb 2018 i Rijeka 2020. Sad imamo kombinaciju, snimke dronom za veće urbano područje.

Pitali smo ih, a Grad karlovac nam je dopustio korištenje svoje snimke. Ne samo dopustio korištenje nego su nam ustupili i snimke koje sad objavljujemo na našem tms serveru. Snimke su nastale snimanjem dronom i to u 11. mjesecu 2023. godine. Tako da su to najnovije snimke koje imamo.

Za korištenje potrebno je ručno upisati TMS adresu u željeni editor.

Ecco qui, altro luogo dove scrivere, userò questo diario per gli spostamenti, mi pare adatto :-)

A partire da questa domanda sul gruppo Telegram, mi è venuto in mente che fosse utile creare un breve tutorial per spiegare come visualizzare le informazioni delle direzioni all’interno delle applicazioni per modificare OpenStreetMap, che è un argomento, a mio avviso, semplice, ma poco intuitivo per i neofiti del progetto.

Non tutti i nodi hanno bisogno una direzione! Solitamente, i nodi legati a una way possono avere una direzione. Questo perché in OSM le way hanno un senso di costruzione (che viene generalmente indicato con delle freccette sulla way).

My morning walks got replaced by Car driving lessons.

I turn on my GPS and go for driving and after returning I upload the traces to OSM.

I am wondering other than uploading the GPS traces, is there any other way I can utilize my local knowledge to contribute to OSM.

I’m honored to begin my journey as a 2025 Fellow with the Open Mapping Advocacy Network (OMAN) under the HOT Open Mapping Hub – West and Northern Africa (WNAH). Over the years, I have actively contributed to the open mapping ecosystem through OpenStreetMap Sierra Leone and YouthMappers, as a 2023 YouthMappers Leadership Summit Fellow and 2023–2024 YouthMappers Regional Ambassador for West Africa and a Trainer, OSM Sierra Leone. These experiences have shaped my passion for leveraging geospatial technology as a tool for sustainable development, data-driven decision-making, and youth empowerment.

I applied to join the OMA Fellowship because I deeply believe in the transformative power of open data and participatory mapping to promote inclusion, community actions, and resilience. The OMAN Learning Initiative provides a meaningful opportunity to expand my skills in course design, open mapping advocacy, and community engagement, while collaborating with my co-fellow to co-create impactful learning resources that empower local mappers and communities across West Africa. Together with my co-fellow Jimerveille Thierry-Ngouama, we’ll be co-developing the course “Open Mapping for City Management and Planning.” This learning initiative explores vital and practical themes such as: -Open Data for Sustainable Cities -Informal Settlement Mapping -Disaster Preparedness and Resilience -Disability Assessment and Accessibility Mapping -Revenue Generation and Urban Innovation These themes strongly resonate with challenges faced across West African cities, where limited access to reliable geospatial data often hinders effective governance and urban development. Open mapping offers a powerful and practical pathway to strengthen urban planning, disaster risk management, and inclusive infrastructure design ensuring that no community is left behind.

About me

A geospatial tools and technologies enthusiast from the Republic of Congo. First, a chapter’s Vice-President of YouthMappers de l’Université DENIS SASSOU-N’GUESSO, before serving as a Technical YouthMappers Regional Ambassador. Now, more than pleased to shape the future of Open Mapping within the North and West African region as a Content and Community Engagement Fellow at the HOT WNA Open Mapping Hub.

How did I end up here?

Having witnessed the power of Open Mapping, I am dedicated to raising awareness around it and its related tools and technologies. So, when I heard about the Open Mapping Advocacy Network (OMAN) Learning Initiative, I felt excited to dive into it. More interestingly, the selection process to become a fellow in this program was one of the best experiences I have had. Indeed, no interview for shortlisted, the selection team directly provides us task to complete, linked to what is expected of us and what we are supposed to be doing once selected. This process taught me a great deal about situational thinking and problem-solving.

According to my view, why is open mapping so important?

Open mapping is neither just about freely available online maps for getting from place A to B nor collaborative mapping projects anyone can join. It’s really about democratizing locational knowledge for facilitating decision making, helping problem solving, and supporting one’s geographic experience. The reason why the course under development is titled “Open mapping for sustainable cities” and will be subdivided into five (05) modules, emphasizing an introduction and four (04) mapping thematic as follows: informal settlements, disaster management, disability assessments, and revenue generation.

FPAS replica map with custom colours for MetService

A few days ago I found what appears to be a criminaly underviewed video (currently with 81 views) about imagery interpretation. I almost cannot believe I hadn’t seen it up untill now. It’s breif, contains many of the points I’d write to others about, and there’s next to nothing which I dissagree with. A wonderful addition to my feedback toolbelt.

I want to give this video a signal boost in all relevant mapping channels, since it’s a fantastic resource which can help contributors improve their imagery interpretation. An Introduction to Aerial Imagery for New Mappers

The video is titled for beginers, but the fundamentals don’t change; check it out!
