良かった点

・複数の航空写真から吟味してマッピングした

・航空写真だけでもかなりの密度のマッピングが可能だと判明

 → この結果、国内でも中々お目に掛かれない密度へ(しかも農村部で、おそらく私がマッピングしなければ100年は放置されていたであろう)

反省点

・比較的新しい航空写真を見つけることが思いの外難しかった

・やっぱり現地調査を行なってくれるユーザーが居ないと辛いところがある (コンビニっぽい建物にセブンイレブンのポイントを追加してくれるだけで謎の多幸感に襲われた)

・恐らく必要以上に水路をマッピングした地域がある (先日、青い森鉄道や東北新幹線から田んぼを凝視したが、明らかに田んぼである所を水路にしてそうだなと思った)

・was:buildingタグの建物の削除を行なってしまった (これは私の無知。しかし、首都圏などでこれを一々マッピングしてたらとんでもないことになりそうだと推測)

疑問点

・牧草地と耕作地の違い

→現地調査してくれるユーザーが登場するのを待つしかない(訓練された道民なら分かるのだろうが)

・耕作地はどの程度詳細に描くべきだろうか

→正直、クソデカ耕作地はもちろん、ブロック単位の耕作地もあまり好きではない。しかし、離農が相次ぐ現在では一反一反描画するのは現状をマッピングできているとは言えないとも考えられる。

しかし、災害時に使われることや将来的なことを考慮すると、現状のマッピング方法が好ましいと考えている。

・コンビニやガソリンスタンド、集合住宅っぽいものが航空写真に写っていたら、地図メモで残しておくのは有用か

→今後、現在マッピングしている上尾市で検証したい。

月形町でのノウハウは現在精力的にマッピングしている上尾市などで生かせればなあと思っている。

自分1人だったら正直、モチベーションが怪しかったので協力下さった皆さんには感謝しております。ありがとうございました。

Tasking Manager, an open-source project, recently undertook a significant migration: transitioning from Flask to FastAPI for our web framework and from psycopg to asyncpg for our database interactions. FastAPI offers substantial performance improvements by leveraging asynchronous programming and simplifying API development with automatic interactive documentation and modern Python features. asyncpg enhances database interaction throughput with its asynchronous design and high optimization. Despite challenges like the learning curve and extensive code refactoring, this transition promises enhanced performance and scalability, providing valuable insights for the community and encouraging the exploration of FastAPI and asyncpg for similar projects.

For a detailed account of our migration journey, read our full post here. We invite the community to get involved, share feedback, and contribute to Tasking Manager. Your insights and collaboration are invaluable as we continue to innovate and improve in the world of open-source software.

Welcome to the fifteenth OpenStreetMap NextGen development diary.

I am sorry for the delay in the development diary! Due to my participation in the recent State of the Map EU 2024, I had to dedicate some of my time to making the presentations and attending the event. Nonetheless, thanks to other project contributors, we have more highlights to show off! This is the beauty of an open community collaboration 🙂.

Multiple Changeset Bounding Boxes

OpenStreetMap-NG is resolving one of the most common newbie issues on OpenStreetMap while making area monitoring more accurate. Changesets now support incremental and deterministic clustering of changes, enabling multiple bounding box support.

This change is backwards compatible, as API 0.6 and others will continue to return a single bounding box per changeset. This feature will only be available directly on the website, as well as in API 0.7.

Let’s mark the end for issues like these:

Why it’s bad: Everyone monitoring for changes within the bounding box receives a notification. When a single changeset covers half of the world, this leads to a lot of noise, making the system less reliable and difficult to follow.

Implementation of Recent Activity Chart

We have also finished the implementation of the recent activity chart, which is displayed on user profiles. Originally announced in Development Diary #11.

This feature will make it easier to moderate and monitor activity on OpenStreetMap, providing a quick peek at the recent mapping experience of a user.

Updated Geolocation Icon

We have received feedback that the existing geolocation icon is confusing, making some people unaware of this feature. We are now experimenting with a new, more typical design for it:

In the future, we will make the new icon theme match the surrounding icons. Currently, the icon appears a little too thin.

Feature-Parity Process

This week, we have also made progress towards reaching the feature-parity goal. This includes final development of the search functionality and the “Where is this?” feature. We have also corrected a few small bugs and added support for Data Layer alert auto-dismissal.

Simplified Authorization System

During the recent State of the Map EU 2024, I received a hint that the authorization system could be made even simpler, making it easier to test and maintain. We no longer have a separate system for handling user session tokens (cookies); we are now reusing OAuth2 core with a simple wrapper on top of it. Nothing has changed functionally, there’s simply less code. Win-win-win \🙂/.

Sponsors

This two week’s work was sponsored by 17 people!
8 donors on Liberapay, and 9 on GitHub Sponsors.

Department of Disaster Management (DDM) , Thimphu Municipality (TT) and BSc. Environment Management, Royal Thimphu College (RTC) and the Open Mapping Hub Asia Pacific (OMH-AP)

Initiative

Since OpenStreetMap (OSM) is the most accessible data for individuals and agencies for map visualization, geospatial analysis, research, and decision-making, the DDM and TM conducted a one-day session on using spatial data in urban planning and humanitarian efforts. During this session, students learned how to update or contribute point data or Point of interest (PoIs), such as shops, offices, and hotels, to OSM using a mobile app called Organic Map. A session was also included by Mr. Mikko from OMH-AP, the Philippines.

Session on OSM

Who maps the most

For a duration of five days after students were taught how to update OSM, they were encouraged to do mapping by declaring mobile data as prizes for top contributors. Students mapped up to 590 PoIs over 5 days, likely during their time off from college in Thimphu, Bhutan.

Today I realised that it’s probably significantly more efficient (in terms of effort and time) to simply state the reason(s) for (in)validating a task in the task comments, and ask contributors to read the project comments where I can post some more detailed comments, explinations, pictures etc. related to common mistakes I find while validating the project.

This efficiently accomplishes at least four objectives;

  1. Contributors who read the comments recieve feedback regarding their contributions
  2. It is easier to get an overwiew of quality issues in the project.
  3. It saves time in comparison to giving feedback on each individual task.
  4. Contributors to the project who map areas yet to be mapped and read the project comments can get a heads up, before contributing increasing the likelihood that they will avoid making the same mistakes.

Farewell to giving feedback on every task, unless it is truly unique. 😌

My journey with mapping began during my undergraduate studies in geography at Eastern University, Sri Lanka. My fascination with maps and the potential of Geographic Information Systems (GIS) to solve real-world problems sparked a deep interest that would shape my career. In 2019, I joined OpenStreetMap (OSM), an open-source platform that allows users to create and share maps of their communities. This was the beginning of a transformative experience. Through OSM, I discovered a vibrant community and shared my passion for open data and community development. I quickly became an active contributor, dedicating countless hours to mapping underserved areas in Sri Lanka.

As my involvement with OSM grew, I became proficient in using various mapping tools and mobile applications, which allowed me to conduct efficient and accurate mapping projects. I got appointed as the YouthMappers Chapter Secretary at Eastern University, where I played a pivotal role in promoting open mapping practices among students and local communities. My commitment to mapping and community development led me to join Sarvodaya Fusion, an NGO dedicated to empowering communities through technology. At Sarvodaya Fusion, I organized workshops and training sessions to teach others how to use OSM and GIS tools. These initiatives not only enhanced the mapping capabilities of participants but also fostered a sense of community and shared purpose.

In 2024, my dedication and hard work were recognized on an international level when I honored as the “Mapper of the Month” by the United Nations. This prestigious recognition highlighted my significant contributions to the OSM community and my role in promoting open data and mapping. My journey with mapping took another exciting turn when I was selected for the YouthMappers Fellowship Program in Jamaica on 2023. This opportunity allowed me to collaborate with fellow mappers from around the world, exchange knowledge, and contribute to impactful mapping projects. The fellowship enriched me to understand of global mapping challenges and provided me with new perspectives and ideas. Throughout my journey, has remained committed to using mapping as a tool for social and economic development. My journey with mapping is a testament to the impact that dedicated individuals can have in building resilient and informed communities through open mapping. I continues to explore the potential of GIS and contribute to the global mapping community.

I am mapping every day, but i am unable to write a diary entry for every day i map. due to limited internet access and being on the move most of the time.

During the past 4 days, including today, i have mapped Villages Mesul, Cerjan, Bishqem and Papër and i have done a lot of mapping in Kosovo.

I have also gotten some private message these days to whom i have been unable to respond, so i ask you to bear with me. I will be back home in a week and will catch up with you all. Thanks a lot for contributing on mapping Albania! <3

Good morning!

This is my first diary entry. I am new to OSM and have a lot of learning and growth to do. I have to say I knew nothing about OSM and am absolutely blown away by how many companies use OSM in their mapping efforts. Truly awesome!

I am starting out building a interactive eruv map using OSM. I am getting lot of help and I am learning all the code words of the OSM community. Learning what for instance nods are points, I think they are called wazes or lines, and relations are a combinations of points and lines. Learning to Tag as well. I am also learning and trying to learn daily the LearnOSM website. Going through the tutorials are very good. I am enjoying doing it, yes it is frustrating at times but that is learning.

I am building this eruv map for my community and looking to embed it on the Synagogues website. Learning right now I am learning about the editor and how to place points and lines.

I will keep posting every so often my wins, loses, and how it worked for me.

On May 24, 2024, I led an “Introduction to OpenStreetMap (OSM)” training session at the Geography Department of the University of Laos in Vientiane. The session was organized with the help of Professor Sonnasack Phaipasith, who provided translation support and organized the venue and invited his students. We had 15 participants, all students of Geography - eight women and seven men.

This training was part of my assignment with the Humanitarian OpenStreetMap Team’s (HOT’s) Open Mapping Hub - Asia Pacific (AP Hub) Guru Fellowship program. The Guru Fellowship program is a program aiming to engage with and upskill OSM mappers to fully utilize their knowledge and experience in advancing the Open Mapping movement in the region. Within this Open Mapping Guru Fellowship program, I also organized a Happy Hours OSM mapping meetup in Vientiane as well as 2 online trainings about “Mapping Relations” and “Good practices of Tagging Names in OSM”.

Training participants

For this in-person “Introduction to OpenStreetMap” training we met from 8:30 AM to 12:30 PM at the University of Lao. We covered the basics of OpenStreetMap, how to use it effectively and explored how mapping and OSM skills can benefit young Geographers in building their career.

The training covered the following topics:

  1. Understanding OpenStreetMap, Its Data, and Community We started with an overview of OpenStreetMap, including its website, wiki, and community. We also compared Google Maps with OSM to highlight their similarities and differences.

  2. Accessing and Using OpenStreetMap I demonstrated various ways to access and use OpenStreetMap data. Participants explored the OSM website, Organic Maps, the QGIS plugin (quickOSM), the HOT export tool, Geofabrik, and Overpass Turbo. This session showed how versatile and accessible OSM data can be.

  3. Contributing to OpenStreetMap One of the key parts of the training was learning how to contribute to OpenStreetMap using the iD editor and briefly showed the JOSM editor. These tools help users add and update map data, making it easy to contribute to the community.

  4. Local Initiatives and Community Involvement We also talked about local OSM initiatives and how participants can get involved. I shared information about the Lao OSM community and HOT’s work, encouraging everyone to contribute to these efforts.

  5. Skills and Opportunities for GIS Professionals The session wrapped up with a discussion on the skills needed and opportunities available for GIS professionals in Laos. This part was important for those looking to use their new OSM skills in their careers.

The “Introduction to OpenStreetMap (OSM)” training at the University of Laos was a great success and fun for everybody. With support from the Geography Department esp. Mr. Sonnasack Phaipasith, the participants learned about OSM and gained some practical skills they can use in the mapping community and their professional lives.

This training was a valuable step towards building a more connected mapping community in Laos and beyond.

Getting to know OpenStreetMap (OSM)

I love maps. Since I was a kid, I was fascinated by the old atlases and maps I found in my grandfather’s drawers. I could spend hours learning about countries’ borders, historic events, and the world through those thematic and topographic pieces of art and science.

Circumstances had it that eventually I ended up with a Masters Degree in Geography, unleashed onto the professional world, trying to make some positive contributions, some might say, “to change the world”, on the beautiful island of Lombok, Indonesia.

I still remember, when back in 2008, my colleague showed me an article about a crazy project to make a free map of the world, basically by using GPS tracks as the main data source – high resolution satellite imagery as we know it now, was not yet accessible. Crazy idea, impossible, overambitious, were a few thoughts that popped up. Though, “why not give it a try” and add a few roads and places in my neighborhood. I don’t think those few edits made a big difference to OSM – but it thought me of how to use and contribute to OSM.

Becoming an OSM contributor

The following year I ended up living and working in the town of Putussibau, Kapus Hulu District. Take a dart, throw it somewhere onto the middle of a map of Borneo, the biggest Island in Indonesia, and if you slightly missed the exact middle a little bit to the north-west - that’s where I found myself. Surrounded by amazing nature, amid local Dayak, Iban, Punan and Malayu as well as other Indonesians who had moved there more recently from other parts of the archipelago, I was teaching GIS and conservation, mapping forests, customary boundaries and the manifestations of an increasing human footprint there – road infrastructure, oil palm plantations, gold mining areas and the like.

While my maps slowly filled up with data of villages, roads, rivers, online maps such as Bing and Google had very little to say about Putussibau and Kapus Hulu, mostly just showing a huge expanse of – “empty, nothing”.

Here is where my OSM journey really started. I figured out how I could include my data into OSM, started to digitize more rivers, roads and when I left two years later OpenStreetMap had probably the best publicly available map data for Putussibau Town and many other areas in Kapuas Hulu. Somehow it felt good to put “a place onto the map”, to be able to fill some void.

The idea of OSM, to create a free map of the world suddenly did not sound so crazy anymore – I realized that if many people collaborate with a common goal, the seemingly impossible is suddenly within reach.

The value of collaboration and community

Back on Lombok, I started to share my OSM experiences, encouraged and helped others to also share their data with the OSM community and continued to map here and there. It was very helpful that at the same time Microsoft started to allow the use of their Bing satellite imagery to trace features for OSM – as it made contributing to OSM much easier and allowed to also excite non-Geographers or mapping people to become part of the OSM community. OSM also became a good way to start teaching about mapping and GIS and give students the feeling that after a relatively short training, they could already create something useful – not just some training exercise data, to be discarded afterwards as in my previous mapping trainings.

While working on Lombok Island and the province on East Nusa Tenggara I met with people from the Humanitarian OpenStreetMap Team (HOT), who were supporting projects, focusing on rural development in eastern Indonesia and disaster risk reduction in Jakarta through training mappers, supporting mapping missions and developing tools and leveraging the OSM ecosystem.

As a self-taught hobby OSM’ler this was exciting and I was lucky enough to find ways to become more deeply involved in some of their and their partners’ project activities, gaining a much better insight of OSM, see how OSM can be used by government agencies, communities and others to really make a change and also experience some of the many challenges, meeting inspiring people and making new friends.

What I also like about OSM is that while easy and simple to contribute and use, below the hood, it is nevertheless a complex system of data infrastructure, mapping and data access tools, evolving mapping standards & best practices and last but not least, it’s a community of like-minded people each with their own strengths but sharing the common interest for free and open data and mapping. There is always something new to learn. Engaging with OSM taught me a lot and pushed me to expand my understanding of GIS and working with data and within a community.

Making and impact through sharing data with OSM

When I eventually left Indonesia for Myanmar, I made sure I was able to share as much relevant data as possible from my work with OSM, e.g. adding a wealth of thoroughly mapped roads and points of interest for Mataram, Lombok’s biggest city, and parts of north-western Lombok. And if you find yourself sipping a cocktail at a beach bar on the (in)famous Gili Trawangan Island, keep an eye on the street signs. You’ll likely see roads named after local sealife—names created, agreed on and made official by the local community, with assistance from Gili Ecotrust and partners, using OSM data and derived maps.

Very often, so-called development projects go to great efforts to create a lot of quality geospatial data. Unfortunately, very often, at the end of those projects those data disappear in data archives accessible to only a few, are forgotten or lost entirely. With a little extra effort, some of those data could (and should) be made available to the public. It would be effort well spend to filter out sensitive data, remove less relevant project specific data, document and transform the remaining data and share those with OSM or other open data platforms.

OSM in Myanmar

I was fortunate to arrive in Myanmar at a time when the country’s fortunes seemed to finally be heading in the right direction. Astonishing reforms were initiated, bringing a new sense of development, openness and democracy, and improving the prospects of the country and the lives of millions.

With people just starting to get access to internet, there was obviously no vibrant Myanmar OSM community yet, nor did many people use (or know how to make use of) maps anyway. Nevertheless, things changed when internet became more and more affordable and with the likes of Grab “forcing” people, or at least the cab-drivers, to use maps. Organizations and individuals increasingly mapping in and using OSM.

Working initially for a conservation NGO in the country, I experienced first-hand the scarcity of quality large scale geospatial data. MIMU, a UN organization did and still does a great job trying to provide medium and small scale geospatial data, but if you are looking for geodata to make maps and conduct analysis on anything going beyond township level scale, the only options you had was illegally using topographic map scans “leaked” from a military affiliated government department or outdated topographic maps produced by the colonial government a century ago. For large scale map data, suitable to make maps on village tract or site level, you were completely on you own.

When, after some years, changing jobs to working on a project with a strong focus on geospatial data with the Centre for Development and Environment (CDE), new opportunities to more strongly reengage with OSM opened.

CDE jointly with Fauna & Flora International (FFI) translated essential OSM training materials from learnOSM, the Official HOT OSM learning materials into Myanmar https://learnosm.org/my and we provided funding and technical assistance to Phandeeyar, a Yangon based technology seed accelerator to organize and support the emerging Myanmar OSM and open data community. Furthermore, I was able to provide numerous OSM beginner trainings in Yangon, the largest city in Myanmar, and in the coastal city of Dawei, which became my home for several years.

It was always exciting to see how many OSM beginners enthusiastically mapped their home villages and areas they had a personal connection to. Some of them continued to contribute by mapping large areas to the extent that I wondered where they even found the time to do so.

I believe that contributing to OSM is most effective when organized as a community with clear goals in mind. A collaboration between the Red Cross, Missing Maps, CDE, and Phandeeyar to map the city of Mawlamyine in 2018 is a perfect example. https://www.missingmaps.org/blog/2018/09/24/mapping-in-myanmar/

OSM in the face of Myanmar’s new realities

Tragically, Myanmar’s path to progress was abruptly halted. Following the military takeover in February 2021, the country has largely descended into crisis, chaos, and conflict. Poverty has risen sharply, security has severely deteriorated, political freedoms have been significantly reduced, and armed conflict taking place in many parts of the country.

Many, especially young people, have either left the country or joined the resistance. The space for open dialogue has diminished, making ends meet becoming a daily challenge and in the face of reality, the once-ubiquitous smiles of the Myanmar people are becoming increasingly rare. In light of this dire situation, the once-active Myanmar OSM community had largely disintegrated.

Civil society, humanitarian organizations and passionate individuals are trying to provide basic assistance to the most vulnerable people in Myanmar. Having access to reliable maps can help them to be more effective. If access to geospatial data was challenging during Myanmar’s better years, it has only worsened since. While google maps for Myanmar has improved significantly over the last decade and is used widely, its terms-of-use and access limitations severely limit its usability, not to mention the lack of detail and coverage, esp. in rural areas.

I believe that OSM, as the best available open mapping platform offering detailed large-scale geospatial data, becomes even more valuable in such circumstances. As such me and my organization is working to re-activate the Myanmar OSM community, support Myanmar OSM mappers, and collaborate with HOT, e.g. to provide technical assistance and facilitate remote mappers to help improve essential OSM data for Myanmar.

MyOSM, our Myanmar OSM group, has since grown in numbers and skills and it is amazing how much myOSM has already been able to map, improving data on settlement areas, roads, rivers and other features that can be mapped remotely – field mapping for security reasons is currently highly restricted.

HOT’s Open Mapping Hub - Asia Pacific (AP Hub) Guru Fellowship program was instrumental as it provided four myOSM members essential skills for OSM focused training, mapping and validation. Furthermore, joining the 5 months fellowship program fostered a sense of community and belonging to an international group helping each other and joining hands to improve OSM. Equipped with the new skills, we are more confident in our OSM activities and can better share those skills with and help other OSM mappers.

Expanding to Lao PDR

My journey with OSM is far from over. Currently, I am based in Vientiane, the capital of Lao PDR. Access to large scale geospatial data is also a challenge in Laos and unfortunately there is no strong Lao-OSM community yet – with most OSM mapping here done by individuals, mostly foreigners. Though our OSM-Laos group is trying to change this by organizing trainings, outreach activities and smaller mapping missions.

In my case, I helped with a OSM beginner training at the Department of Geography, National University of Lao and organizing a Mappy Hours Event – a mapping meetup for OSM mappers in Vientiane.

Building an active community here may seem challenging, but so did the idea of creating a free map of the world back in the mid-2000s. If we believe in our goals and work together, nothing is impossible.

Happy mapping, everyone!
