Started this year with a weekend mapping project: locate and map public traffic camera feeds from city’s website. Day 2 and I’m halfway done, about 130 out of ca 260 have live feed links now. Roughly 5 of them weren’t previously mapped at all.

Purpose of this diary entry is to save the checker scipt in publicly accessible place for unlikely reuse. Script scrapes all possible camera IDs and cross references them against already mapped feeds via overpass.

Link to the Time Lapse Video of Amaravati (2015-2025)

Time lapse video of OSM has been of interest to me for more than 10 years. I learned to use QGIS in 2015 and made a physical map of Andhra Pradesh in my first attempt. Learning QGIS with its myriad menus and concepts of GIS was daunting to venture further during my infrequent attempts. Finally I made my first time lapse video after 10 years. I found OSM contributor radiotrefoil's diary entry on the subject posted about an year back very helpful. Still I had to struggle to make a good video for OSM edits for Amaravati, the green field capital of bifurcated Andhra Pradesh, a province of India. This is an attempt to document my learnings and make it easier for others.

Mi sono preso l’impegno di mappare per bene il mio quartiere, e mi sono accorto che ci sono diverse cose da aggiornare, senza contare che alcuni numeri civici sono messi quasi a casaccio, ma poco male, mi sto divertendo un sacco e piano piano sono sicuro di poter fare un bel lavoro. Per quanto riguarda le informazioni dei negozi, sto cercando di metterne il più possibile, numero di telefono, sito web, e addirittura a pagina Facebook.

Mi piacerebbe anche dare una rinfrescata grafica proprio a open street map, perché ne avrebbe un gran bisogno, ci sono cose che sono pugni negli occhi, tipo le icone viola, ma sinceramente non so chi “controlla” la grafica di OSM, e non saprei neanche dove iniziare a cercare per proporre la cosa.

Una cosa fighissima da fare sarebbe integrare il protocollo Activity Pub in mondo fa poter interagire con il social federati, come ad esempio mastodon, ma anche li non saprei da dove cominciare per proporre la cosa.

Detto questo, non pensavo che OSM avesse una community molto attiva e la cosa mi fa piacerissimo e mi fa venire voglia di mappare sempre di più e meglio

今天是2026年1月1号,前段时间一直想要在我的世界中复刻自己的县城,一直不知道从何下手,从高德api到arnis的生成,由于数据缺失和技术受限没能完成,这几日开始填补osm的数据,以便后续使用。 今天完善了油竹的部分区域,包括青田之心青田中学伯温中学和部分居民区,继续加油!也希望有人能够加入我的这项工作。

Last weekend I traveled to the west coast of Java, specifically Anyer in Banten. The journey was done by train from Jakarta to Cilegon, followed by a local shared minivan taxi to Anyer.

Throughout the trip, I collected field observations using Sakumap. The result was a raw GeoJSON file containing coordinates and timestamps for each entry.

For observations I considered significant, I wrote a detailed report on the OSM Wiki. Less critical features such as restaurants, fuel stations, farms, and forest areas were added directly to OpenStreetMap by importing the Sakumap GeoJSON into iD Editor or JOSM, without additional documentation on the wiki, as the overhead did not seem justified.

He intentado hacer unos cambios en el mapa para que nos dirija por un trayecto más corto y sin curvas necesasias, además de excrementos de vacas. Conozco esa carretera. Los Gps gratis que usan open street map dirigen por una zona que no debiera. Si ese mismo trayecto lo indico con el gratis de la marca que no puedo escribir o con el famoso que fué diseñado por una empesa de israel pero ahora pertenece a la gran multinacional que no puedo escribir por normas de osm, dirige por donde es rápido, más directo, sin excrementos de vacas. Y entonces mi pregunta es ¿que cambios se necesitan para que funcione correctamente? es que no es lo único que hacen mal los gps que usan open street map. Tanto que es gratis, que no depende de una empresa pero funciona mal. para que me lleve por unas escaleras, por una zona pantanosa o cualquier zona por la que no se puede ir, prefiero W _ A _ Z - E o M -A - P - S

Alguien me puede responder por qué funciona mal? No me gusta depender de un gps de una multinacional, pero si tengo que elegir la seguiridad en la carretera, lo elijo.

Gracias por la respuesta.

Hey, this is my first post here and I think it would be fitting if I’d tell all of you why I even created an account here and started making my own edits on OSM.

Background

First, you need to know that I’m a student at Westpomeranian University of Technology in Szczecin in department of computer science. That means that me, and 90% of people there are nerds with interests like: trains, transportation, hacking, programming, opensource and… well… maps.

How it started?

It all started during a normal day at University. We were walking from one building on campus to another when I noticed that my friend has a map open with a lot of pins and some questions on his phone. I asked him what it is and he told me about “Street Complete”. That’s it! I already knew that my ADHD butt found a new hyperfocus for the indefinite amount of time. I installed it and 3 of us started adding the detail information on the map around our campus.

Street Complete era

So… for the next few days I had Street Complete open on my phone during every tram ride and every walk. I wanted to fill every question. This took some time, I answered some question around the Poland in Szczecin, Kielce, and recently in Wałcz.

Taste for more

Right now I’m at my family house in a village where most OSM information where updated several years ago. I went on a walk and - as usual - opened Street Complete. It was great until I came by a few buildings that were demolished few years ago, but were never deleted from the map. I knew that I can’t just leave them there and I couldn’t do this from Street Complete. I went back home and booted my laptop. I opened the OSM editor for the first time and started making edits around the village. Adding houses that were build recently, deleting stuff that no longer existed, updating the zones, etc.

My diary entries are all my own thoughts and do not represent OpenStreetMap, The Humanitarian OpenStreetMap Team (HOT) or any organisation using the HOT systems. Any errors are all my own work.

Back in January 2025 I found myself mapping a HOT project in Kulob, Tajikstan. I had wanted to find a project to gain some experience of mapping water features and this project fit the bill. In support of a local tuberculosis screening programme, Médecins Sans Frontières required the update or addition of roadways, waterways and residential areas. No buildings. This was not a high priority project, so did not get much interest from the general HOT community. Only 11 mappers, with 3 completing tasks. Local mappers would be updating feature and area names. I mapped about 85% of the project, so I have a little stakeholder interest in the data use.

Around the same time I had started attending the Missing Maps London on-line mapathons early in month and mid-month events. As well as getting mapping advice, this put me in touch with the wider HOT mapping community. It turned out that Jorieke, the Kulob project manager, is a regular of the Missing Maps sessions. Along with several of my HOT on-line mapping colleagues, we met at SOTM Europe in Dundee .

Today Jorieke sent me a link to a podcast interview with one of the MSF doctors using the OSM data in Kulob. We rarely get to know about how our mapping supports end users, you can hear it here and discover other mapping related podcasts.

I was visiting Sa Pa, Vietnam, and navigating with Organic Maps. I was looking for a street that would bring me back to the city center. I could not see any on OSM or Google Maps. I walked for a while and was able to see a street that led in the right direction. It turns out that it connected to another street that brought me where I wanted to go. This made me realize how much of the useful information in maps depends on people walking, running, or commuting through those streets. You cannot see these kinds of streets from satellite images. You can only know them, but knowing them, you may not use GPS tracking to record them. I think this leaves only runners and anyone who likes walking to discover most of the streets that are not currently on the map.

কাতিলা দারুস সালাম ক্বওমী মাদরাসা রাজশাহী জেলার বাগমারা উপজেলার নিচু কাতিলা এলাকায় অবস্থিত একটি পরিচিত ক্বওমী ধর্মীয় শিক্ষা প্রতিষ্ঠান। মাদরাসাটি নাগা বাজারের উত্তর পাশে অবস্থিত এবং নাগা বাজার থেকে আনুমানিক ১২০০ মিটার দূরত্বে অবস্থান করছে, যা স্থানীয় সড়ক ও পায়ে চলাচলের মাধ্যমে সহজেই পৌঁছানো যায়। প্রতিষ্ঠানটি আশপাশের গ্রামগুলোর শিক্ষার্থী ও ধর্মপ্রাণ মানুষের কাছে সুপরিচিত।

এই ডায়েরি এন্ট্রিতে মাঠ পর্যায়ে যাচাই (ground survey) ও স্থানীয় তথ্যের ভিত্তিতে মাদরাসাটির সঠিক অবস্থান, নাম ও প্রাসঙ্গিক ট্যাগ যাচাই করে OpenStreetMap–এ সংযোজন/হালনাগাদ করা হয়েছে। এর মাধ্যমে নিচু কাতিলা, নাগা বাজার ও পার্শ্ববর্তী এলাকার শিক্ষা প্রতিষ্ঠান সংক্রান্ত ভৌগোলিক তথ্য আরও নির্ভুল ও ব্যবহারযোগ্য হবে বলে আশা করা যায়।
