Kdo vlastně vytváří ostrá geodata? Před očima hned naskočí postava geodeta s laserovou stanicí na stativu, nebo člověka s GPS přijímačem pobíhajícího po poli. Ale když se vyskytnu v prostředí lidí, kteří se živí úplně jinou prací v krajině, tím víc si uvědomuji, že kolem nás vznikají obrovské zásoby prostorových dat, o jejichž přítomnosti ani jejich autoři mnohdy nevědí.

Traktorista, který celý den jezdí po poli, dávno není jen řidič stroje. Je to aktivní sběrač geodat. Systémy přesného zemědělství, které dnes jezdí v kabinách zemědělských strojů, jsou malé GIS platformy. Terminály jako John Deere Operations Center, Trimble GFX nebo česká platforma CleverFarm pracují s prostorovými daty. Řidič může okamžitě zaznamenat bod, linii nebo plochu s přesností na centimetry, pokud má k dispozici RTK korekci. Šachta meliorační sítě uprostřed pole, vyčnívající balvan, osamocený strom, podmáčená plocha nebo sloup elektrického vedení jsou v systému záznamem s GPS souřadnicí. Software data zapamatuje, příště obsluhu varuje a podle nastavení upraví cestu a automaticky zvedne pracovní nářadí.

Formáty, ve kterých se data z traktoru ukládají, jsou převoditelné do světa otevřeného GIS. Standard ISOXML je sice trochu průmyslové esperanto, ale export do Shapefile nebo GeoJSON je u většiny platforem možný. Přesto tato data takřka nikdy neopustí uzavřené firemní systémy. Zemědělec je vnímá jako výrobní know-how. Vědět přesně, kde je pole podmáčené nebo kde leží kamenná mez pod ornicí, to má pro hospodaření skutečnou hodnotu a tu nechce sdílet s konkurencí. Ale stejný zemědělec rád využívá jiné otevřené informace. Jako např. Intersucho, Agrorisk, nebo ClimRisk.

Agradeço, desde já, a sua leitura… Dedico este breve artigo aos cinco anos e algumas semanas desde que comecei a editar no OpenStreetMap, e atingi mesmo 400 sessões de edições (aquando do momento de escrita). Eu pelo menos festejei um minuto :) Na minha opinião, é muito importante contribuir para a sociedade através do OSM, apesar de isto não ser a minha primeira prioridade. Claro que tenho a vontade de continuar a editar o mapa, acabando por ajudar aqueles que desfrutarem do site. Cumprimentos, e até breve.

This post presents the results of a student project carried out by the following group: Pierrick Causeret, Humbert de Chastellux, Paul Enjalbert and Othman Ouhaddou.

Introduction

This project is a follow-up of last year’s project Shade-optimized routing paths for pedestrians which introduced a shade routing calculator for OSM. Our objective was to make this project available on mobile.

Our github repository

Choosing an App

We first had to choose an app or website to work on. We wanted something easy to publish for us and easy to install for potential users. It also needed to work on both Android and iOS. This excluded all apps that didn’t have plugins or ways to customize them without editing the core code. With all those constraints, we settled on OsmAnd.

Creating the shade data

The full pipeline integrates the previous project, which is the calculation of the shade percentage for each way. This information is then added in the .pbf file as a tag, and then converted to .obf for the app.

I’m new to this.

I did what most people probably do and added/adjusted footprints of houses in my neighborhood. Great but I soon noticed that there were choices to be made about what did or didn’t get included, what level of detail to go to, etc. and no really obvious source of guidance about that.

Which is probably just as well, because if there were masses of prescriptive guidance about every little thing a new user would get buried. Anyway. I settled on what seemed reasonable to me and fleshed out the neighborhood a bit. Fun.

I’m a private pilot, so I checked out my local airport to see how things looked there. It was really quite good in some respects, if a little out of date. But again since there’s no guidance the previous editors had just made reasonable assumptions and got on with it. I noticed a few taxiway connections were missing (I taxi along them regularly so I know they’re there!) and added them. Then realized that the previous editor had only been adding taxiways that correspond to the painted lines. Reasonable but in reality things are more joined up than that. Food for thought.

So I thought I would check out a large nearby airport. Whoever did this has made a different set of assumptions about what a reasonable level of detail is. Nothing wrong with them, just different.

Then I checked out Chicago O’Hare. Wow. Someone went to town here. Every single parking spot in the parking garage is individually mapped. That seems excessive (and dragged my machine to it’s knees as well). I’m sure some aggregation would be better. Never mind.

Checked out Newark. Much more reasonable level of detail here. But I suppose that depends on what you expect people to use it for. JFK is different again.

O Município de Saúde receberá um novo Colégio Estadual de Tempo Integral, este que será construído no perímetro rural da cidade.

O Colégio Modelo Ernesto Carneiro Ribeiro iniciou suas atividades em Saúde em 1902 na Praça Ruy Barbosa, centro da cidade; recebendo uma nova sede no Bairro do Beco em 2008; e agora, ganhará uma nova estrutura próxima do Bairro Nova Saúde.

A estrutura será construída pelo Governo Estadual da Bahia num terreno antes pertencente à prefeitura, agora doado. Ao que se sabe, não há data prevista para o início da construção.

Demais obras no município:

• Urbanização da Praça da Vila Lelinha; (iniciado)

• Urbanização e Drenagem no Alto da Santa Cruz;

• Unidade Básica de Saúde no Bairro do Cardoso;

• Modernização do Mercado Municipal de Carnes - futuro Mini Shopping;

• Revitalização do Mercado Municipal;

Wraz z wprowadzeniem linii nocnych komunikacji miejskiej w Legnicy zamknąłem trwający kilkanaście miesięcy projekt dotyczący transportu zbiorowego w Zagłębiu Miedziowym. Kolejno zostały wprowadzone sieci komunikacji autobusowej w Polkowicach, Lubinie i Rudnej, Głogowie i Legnicy wraz z gminami ościennymi. Na obszarze podległym opracowaniu, obejmującym 2734,94 km2, mieszka ok. 400 tys. osób. Według moich szacunków był to największy powierzchniowo i ludnościowo fragment obszaru Polski, pozbawiony w OSM opracowania komunikacyjnego.

For some reason, the sidewalks near main roads in Sandy have been deleted without much warning. I just have to question what is with these changes and who is responsible for removing the work of mine and others.

Hello,

I recently noticed that Someone, Which I do not know of, Has vandalised clyst vale by Removing the entire school, and replacing it with a sainsburys, ive wrote this to alert a mod to hopefully revert the changes at clyst vale

OpenArdenneMap is an open-source map style designed for the production of topographic maps for printing. Based on OpenStreetMap data, it is available for use with QGIS and the Mapnik/cartoCSS libraries. Here is the winter 2025–26 release.

I started working on OpenArdenneMap about nine years ago. My aim was to create a map style for producing high-quality topographic maps intended for printing, using mainly OpenStreetMap data. The main challenge is to automate map production, to limit ‘manual’ corrections as much as possible (without eliminating them entirely). Since then, the style has been used in several mapping projects: together with colleagues, I have set up a website for downloading hiking maps (hiking.osm.be) and have been able to test the deployment of a tile server on https://www.nobohan.be/webmaps/oam-tile/.

One of the most memorable phases of my OpenStreetMap journey was being part of the Autumn Mapping Sprint 2025, sponsored by Youth Innovation Lab. This was a funded mapping sprint that lasted for one full month, making it both exciting and challenging at the same time.

What made this experience even more intense was that, during the very same month, I was also involved in a one-month field campaign in Dolakha district as part of my studies. Managing both at the same time was not easy.

My days were filled with fieldwork—collecting data, traveling, and completing academic responsibilities. And yet, despite the physical exhaustion, I stayed committed to mapping. Every evening, I tried to make time—sometimes small, sometimes longer—to contribute to the sprint. It required discipline, time management, and a lot of determination.

There were moments when I felt overwhelmed, but I didn’t want to give up. Being part of a funded program and representing myself among advanced mappers motivated me to keep going. I reminded myself why I started this journey and how far I had already come.

Throughout the month, I continued mapping—adding buildings, improving roads, and refining data with care. Even with a busy schedule, I managed to stay consistent and complete my contributions.

Being recognized as one of the advanced mappers during this sprint made the experience even more meaningful. It wasn’t just about mapping anymore—it was about proving to myself that I could handle challenges and still stay committed to my goals.

Looking back, this month feels like a true test of my dedication. Balancing fieldwork and mapping taught me resilience, time management, and self-belief.

This experience showed me that no matter how busy life gets, with determination and passion, I can always find a way to keep going.

Looking back at my OpenStreetMap journey, two dates will always hold a very special place in my heart—June 21 and October 14.

On June 21, I achieved something I had been working toward for a long time: I became the top mapper in KU Youth Mappers. That moment felt surreal. From the days when I was just learning how to draw my first building on the map to reaching the top position—it was a journey filled with patience, consistency, and continuous learning. Every late night of mapping, every small correction, and every effort finally felt worth it.

But the journey didn’t stop there.

On October 14, I reached another incredible milestone—I became a top mapper in UN Mappers. This achievement felt even bigger, as it connected my work to a global level. Contributing alongside mappers from around the world and being recognized among them made me realize how far I had come.

These milestones are not just about rankings or titles. They represent growth, dedication, and the impact of consistent effort. From starting out as a beginner to becoming a leading contributor in both university and international communities, my journey has transformed me—not just as a mapper, but as a learner and contributor.

Sometimes I pause and think about how it all started with simple curiosity. And now, those small steps have led to achievements I once never imagined.

This journey reminds me that with passion and persistence, even the smallest edits can lead to the biggest milestones.

Ihr wisst ja, ich hab’ einen OpenStreetMap-Fetisch :) Schon sehr lange trage ich gemeinsam mit der Schweizer OSM-Community die Idee rum, dass die ~2000 erfassten Gemeindegrenzen in OpenStreetMap besser gepflegt werden sollten.

Diese wurden vor ~14 Jahren in einem sogenannten Import in die OpenStreetMap-Datenbank eingepflegt und seither bei Gemeindefusionen Anfangs Jahr immer mal wieder gepflegt, aber nicht in toto überwacht.

Vor einiger Zeit habe ich im OSM Forum die Diskussion zur Grenzpflege begonnen, das dort angesprochene Tool der serbischen Community ist zwar sehr toll, aber der Umbau auf die Schweizerischen Gegebenheiten hat nicht befriedigend geklappt. Dies trotz der tollen Hilfe der SOSM mit einer virtuellen Maschine (mersi Datendelphin im Speziellen) auf der SOSM-Infrastruktur. Auf dieser VM lief das serbische Tool mit Anpassungen für die Schweiz, war aber nur schwer zu “bedienen”.

In einem Projekt bei der Arbeit habe ich mich etwas eingehender mit den sog. GitHub Actions beschäftigt, mit denen es möglich ist, ja nach Zustand eines GitHub-Projektes Aktionen durchzuführen, die ebenso auf einer virtuellen Infrastruktur (aber halt von Microsoft laufen). Eine solche Action baut beispielsweise aus etwas LaTeX-Code, der online liegt automatisch meinen Lebenslauf (ich hab’ keine Bewerbung offen, brauchte aber letzthin aus anderen Gründen einen Lebenslauf). Oder aus etwas Textschnipseln eine Webseite und ein PDF, das eine Pubikation ergeben wird.

Item, Programmcode im Internet etwas machen zu lassen, ist mit solchen Actions einfach, schnell iterierbar und etwas weniger komplex, als per ssh auf einem Server Python-Code laufen zu lassen.
