I am two days late to write this post. Life gets in the way. However, I felt I should have this in writing. On 6 September 2025, after 11:30 PM, I suddenly realized that the ending day marks something significant. It marks the 10th year completion of my journey with OpenStreetMap. 10 years ago, on this day in 2015, I entered a workshop arranged by Save the Children International in Bangladesh. The workshop was arranged by a project named Kolorob (Bengali word for the sound of a lot of people cheering together) who were training youths on how to edit OpenStreetMap. Little did I know back then that it will entirely change the direction of my life.

10 years since 6 September 2015 consists of 3654 days. Checking my HDYC told me that I mapped 3425 days in that 10 years. That is about 9.38 years of mapping each day. It felt quite overwhelming. Mapping became such an integrated part of my life that it hardly feels something I do, rather something automated that is to be done regularly.

It was a rewarding journey, mixed with bittersweet memories of field mapping in hot summer days in the sun, venturing to unknown areas for GPS tracks, remotely mapping areas after areas that I will probably never visit, spending hours after hours on validating, figuring out how to best map an area, learning new tools, plugins, taking workshops, teaching and training new mappers, solving data collection problems, and so on.

Over time, due to various aspects of life and career, I drifted apart from organized mapping community. However, my mapping continued. I kept mapping unmapped areas of the world. My joy is to take a part of the world with no features mapped and then completing it, literally putting it on the map.

I hope to continue my mapping journey, one day at a time.

Hello

y first day in mapping was sweet and exciting. I felt good to know that even small tasks I did could help improve global maps. It was interesting to discover how roads, buildings, and other features are added, and I enjoyed learning while contributing to something meaningful. That experience motivated me to keep mapping and to grow my skills further.

Hello OSM friends! I’m Bhausaheb…… from Nashik, working in GIS Industry as an GIS Engineer. Recently, I have been mapped new buildings around my locality using ID Editor.

(My first diary entry, am I doing this right?)

I’ve been mapping my beautiful town for now 1.5 or more years. I discovered OSM through a Polish youtuber talking about motorways, and at first I made some small changes, not knowing what I got myself into. Through the years, I’ve fixed the landuse, updated all of the POIs, kept up with constructions, repairs, etc., and did all sorts of detailing.

I’ve reached a point where… I need to move outwards. There is not much left to do except wait for something to close, open or change.

It’s been a heck of a ride. I would like to give the Polish OSM community a warm thank you for helping me out in sticky situations.

Lifecycle Tagging

Lifecycle tagging is the representation of the temporal state of an object (e.g., whether it is under construction, demolished, or abandoned). Since there is no single convention universally accepted by the community, different and inconsistent schemes have developed, making automatic interpretation and uniform data management difficult. In many map editors, there is no section dedicated to editing this lifecycle, which makes it even more difficult for new users to understand how to use the system.

The goal of this project is to devise and implement a method for applying lifecycle tagging in a way that is simple, intuitive, and does not interfere with existing tagging practices.

PR can be viewed here.

Study

Before fully committing to the development of a new interface, a study was conducted to assess which tagging schema is the most popular, consistent and suitable for integration into the iD editor. Many other editors have been. Full study available here.

I also tried many of the existing editors and checked how they supported lifecycle editing.

SIWES Diary – Day 1 Date: 2nd September, 2025 Organization: Unique Mappers Network, Nigeria National Office: Suite 7, Mapathon Center, UNIPORT Mall, Abuja Campus, University of Port Harcourt

Activities:

-Reported to the National Office of Unique Mappers Network and settled into the Mapathon Center.

-Was introduced to the organization’s vision, mission, and the role of open mapping in sustainable development.

-Met fellow IT students including Favour, Alexander and Salvation, who are also undergoing their internship.

-Created an OpenStreetMap account and was tasked to locate my community and count the number of buildings. Many buildings were not visible, so using aerial imagery and my local knowledge, I edited the map by adding missing buildings.

-Since the office router had no internet subscription, I used my personal data for mapping and contributions.

-Received four major tasks for the internship period:

1. Watch the video “The Magic of Maps and Mapping” (YouTube link-https://youtu.be/5MyCtvSBATI?si=g6TM60pmY_oolnT) and reflect on how mapping can be applied to geology.

2. Work on mapping buildings in my community, since the area is not yet globally visible on OpenStreetMap.

3. Research and design an open mapping project that addresses at least five Sustainable Development Goals (SDGs).

4. Participate in research-related tasks assigned by the organization.

-Later in the day, I met the National Coordinator, Dr. Victor N. Sunday, who gave me a formal orientation. He emphasized the importance of my contributions and provided me with a WhatsApp link to join the National Community and Internship groups. Observations/Learning Points:

-Understood the operational structure of Unique Mappers Network and how it collaborates nationally on geospatial projects.

-Learned the importance of open data contribution to global platforms like OpenStreetMap.

In 2025 alone I found vandalism incidents specifically targeting map of Indonesian parliament compound twice, in March and now in late August. Thankfully these are all restored.

What made me sad that some Indonesians don’t understand the OpenStreetMap at all, what they only know in their head is political activism. They do by erasing - or editing - the place of institution they despise. Not really sure if these incidents are unique to maps in Indonesia or there’s international example of politically motivated vandalism of OSM maps?

Memang repot menghadapi sebagian netizen Indonesia yang sepertinya menyalahgunakan peta sebagai alat perjuangan politik ketimbang bantuan navigasi dan informasi.

Selama delapan bulan terakhir, vandalisme bernuansa politik sudah dua kali terjadi: Maret 2025, dengan mengubah batas wilayah negara (yang mungkin gampang diketahui oleh pengurus OSM); dan Agustus 2025 dengan mengganti dua tempat menjadi reservoir.

Target utamanya kalau tidak lain dan tidak bukan kompleks DPR/MPR, khusus untuk Agustus 2025 juga menimpa peta kawasan Polda Metro Jaya (DKI Jakarta). Jika anda punya ketidakpuasan politik di Indonesia, jelas OpenStreetMap bukan tempatnya dan yang anda hadapi adalah dihukum oleh pengurus OpenStreetMap. Mungkin ini satu-satunya vandalisme bernuansa politik di OpenStreetMap

(Update 06/9/2025 - sebenarnya bukan, cek kolom komentar di diari versi Bahasa Inggris, dimana disebut terjadi vandalisme besar-besaran di peta Rusia dan Ukraina terkait perang, serta kasus vandalisme peta TMP Fort Bonifacio di Filipina akibat politik domestik).

Jika anda berpolitik, cobalah untuk menulis di media sosial dan jangan bikin repot orang lain.

Styles for vector tiles are typically written in the MapLibre GL style language. These definitions exist in JSON, which, for various reasons, is not a good language for humans to write in. Software called Charites preprocessed my Street Spirit style to improve readability. This helped a great deal and removed the two largest pain points: no comments and only one file.

Charites’ main features are:1

1. letting you write in YAML instead of JSON,
2. importing other YAML files into the main one,
3. and the use of simple variables to allow common style constants to be set once.

I made use of the first two features, but I still found myself limited by them. I still faced issues where the project’s structure revolved around the styling language rather than what makes sense to a cartographer.

A good example of this was road layers. With Charites I had to have separate files for each layer, so I had separate files for each of the thirteen layers. With glug I was able to have one file for the twelve layers that drew the casings and fill, and one file for the road text layer. This kept related definitions in the same place, which makes everything more readable.

Expressions are essential for writing performant MapLibre GL styles. A simple expression example is filtering to only show labels of larger areas. A filter property such the one below does this.

{"filter":
[">=",
["get","way_area"],
['*', 750, 6126430366.1, ['^', 0.25, ["zoom"]]]
]}

This JSON doesn’t allow comments, so you have to hope it’s obvious from the text what is happening.[2]

Charites lets this be reformulated to YAML

filter:
  - '>='
  - [get, way_area]
  - ['*', 750, 6126430366.1, ['^', 0.25, [zoom]]] # Only show areas larger than 750 pixels at current zoom

It’s a bit better, but the comment shows a limitation of the language. Filtering by area is a very common task. It shouldn’t require a comment to explain the basic math. With glug this instead becomes

… TODO

Desenhá-los de forma individual, além de correto, proporciona um visual mais agradável.
À primeira vista pode parecer desafiador, devido à quantidade e disposição dentro de uma planta solar.

Desenhar um painel e iniciar um processo de copiar e colar não é uma boa prática, pois é muito difícil acertar a posição para que fiquem espaçados e alinhados entre si.

Então, como fazer?

Gridify

Desenhar o contorno de um bloco e usar esse plugin garante tamanho e espaçamento iguais para todos.

1. Para o caso em que os espaços têm a mesma largura dos painéis, a contagem é:
   T x 2 - 1 (onde T é o total de blocos).
2. Para o caso em que os espaços têm o dobro da largura dos painéis, a contagem é:
   T x 3 - 2.

Um ponto negativo do Gridify é que não há opção para adicionar apenas os blocos necessários, sendo preciso remover manualmente os blocos que ficam nos espaços internos — uma tarefa bem trabalhosa se houver muitos painéis.

Então, como agilizar?
