A SPECIAL KEYNOTE ON THE REVISION OF MOZAMBIQUE’S ENVIRONMENTAL LEGISLATION AS AN OPPORTUNITY TO HIGHLIGHT THE IMPORTANCE OF OPENSTREETMAP AND OPEN DATA

---

 

On May 13, 2026, a roundtable discussion was held on the implementation strategy for Mozambique’s national environmental policy, which is currently undergoing a major revision. The event was hosted by the Faculty of Earth and Environmental Sciences at the Pedagogical University of Maputo (FCTA UP-Maputo), in partnership with the Brazilian company IVIDES DATA®.

 

At the invitation of the organizers, Dr. Raquel Dezidério Souto (IVIDES DATA® and UFRJ, Brazil) delivered a special keynote titled “Development & Conservation” (translated from Portuguese), followed by a discussion on the recent Mozambique’s environmental strategy. A copy of the presentation can be found in Portuguese at https://zenodo.org/records/20149423 (*).

Yesterday I cleaned up some map data by removing unnecessary email and unrelated details from several objects. I am learning and trying to follow proper OpenStreetMap mapping guidelines.

把南车站路-中山南路-鲁班路-徐家汇路中间区域的楼全描了，也就是陈欣恬的家、我的家、刘珺瑜的家、我的学校那片。

Lots of data is Switzerland is produced by the cantonal GIS offices (while it might seem to originate from swisstopo it often doesn’t), for example the hiking path/trail data is all cantonal and we can only utilise such data, even when using the data distributed by swisstopo, if the cantonal terms are compatible with our license.

In the following I’m using open in a hand wavy, “close enough” fashion here, and not applying the strict definition as per the open defintion. Class A refers to the federal ordinance definition for generally accessible geo data¹.

To set the scene: Switzerland does not have sui generis database rights regulation or anything similar, nor does it adhere to a sweat of the brow copyright doctrine. Between non-government entities any (minimal) protection available is based on contract and fair competition law. The big exception is geo data where the federal government has written in to law rights that are essentially a “data copyright light” and many of the cantons have followed suit.² There is no relevant case law that I know of and how any of this would work out in an actual dispute is, well, open.

My name is Chukwuemeka Emmanuel Nwosu, a 300-level student of the Department of Geography and Environmental Management, University of Port Harcourt. This diary documents my Industrial Training (I.T.) programme as I undergo it.

After careful thought, deliberation, and counsel from my mentor and my brother, I decided to carry out my I.T. programme at the Mapathon Center of the Unique Mappers Team, University of Port Harcourt. I officially resumed on Tuesday, the 11th of May 2026.

On my first day at the Mapathon Center, I had the pleasure of meeting several interesting individuals who, like me, were present for their Industrial Training. Among them were Matel, who serves as our I.T. representative, and Wisdom, both students from the Department of Geology, Rivers State University, and two of my coursemates from the Department of Geography and Environmental Management: Rania and Obasi Emmanuel. I also learned of a few other trainees I had yet to meet in person.

Notably, I was able to complete a part of the week’s assigned task on this very first day. The task required me to create a map of the University of Port Harcourt, situating it within the context of Rivers State and Nigeria as a whole, while clearly indicating the locations of Abuja Park and Delta Park within the university.

Sono entrato a far parte della community OSM da poco, e nell’ultimo mese ho iniziato a prendere sul serio l’attività, decidendo di impegnarmi per tenere aggiornato e arricchire il database. La domanda è: ci sono dei mappatori in provincia di Varese che sono disposti a scambiare opinioni e consigli?

On the quiet early morning of 18 July 2018, pilgrims from the Mega Arafah Hajj Guidance Group (KBIH Mega Arafah) gathered at the Mega Arafah office near Gedung Sate.

Their first stop was West Java Regional Police headquarters (Mapolda Jabar Gedebage), where pilgrims from across Bandung had assembled.

Я створив невеликий втулок для JOSM з назвою Fillet Tools (fillettools.jar).

Він додає інтерактивний режим для заокруглення кутів ліній, подібний до інструмента «fillet» у CAD-програмах. Основний сценарій використання — контури підʼїзних шляхів та інша точна геометрія, де ручне розміщення кількох точок для заокруглення кута займає багато часу.

Ви можете знайти проєкт у репозиторії GitLab, а завантажити перший тестовий jar-файл — зі сторінки релізу v0.1.0.

Як це працює:

• увімкніть режим Fillet Tools на панелі інструментів (або натисніть клавішу V);
• наведіть мишу на лінію або всередину замкнутого багатокутника;
• біля доступних кутів зʼявляться маленькі маркери (ручки);
• потягніть за маркер, щоб побачити і підібрати радіус бажаної дуги;
• відпустіть кнопку миші, щоб застосувати заокруглення.

Також є дві корисні клавіші-модифікатори:

I made a small JOSM plugin called Fillet Tools (FilletTools.jar).

It adds an interactive mode for rounding corners of ways, similar to a fillet tool in CAD software. The motivation is simple: in the real-world, many objects are not designed with sharp corners. Roads, sidewalks, residential landuse areas, sports fields, running tracks, and other planned infrastructure often have smooth, consistent curves. Mapping these curves by hand usually means placing several nodes one by one, which is slow and often inconsistent. Fillet Tools is an attempt to make this specific editing task easier in JOSM.

You can find the project in the GitLab repository, and download the test JAR from the v0.1.2 release.

How it works:

• enable the Fillet Tools mode from the toolbar or by pressing v;
• move the mouse over a way or inside a closed polygon;
• small handles appear near available corners;
• drag a handle to preview the radius;
• release the mouse button to apply the rounded corner.

Quienes se interesan en la región de América Latina saben que somos relativamente jóvenes en la organización de los States of the Map regionales, iniciados en 2015 después de un encuentro fortuito entre personas apasionadas por OpenStreetMap de diferentes partes de la región durante la conferencia Abrelatam en la Cineteca Nacional de la Ciudad de México en 2014 (mismo contexto en el que se decidió crear un chat de Telegram regional, semilla de la comunidad actual). Posterior a este año, se tuvo cierta continuidad hasta la pandemia, por obvias razones, y también por una desmotivación generalizada de la comunidad, que había vivido cierto “renuevo generacional” que había tenido poca interacción con las pasadas, y, claro, también por la precarización general causada por la pandemia, de la que no nos hemos repuesto ante la situación global actual.

GPS handle (handheld GPS) tidak direkomendasikan untuk digunakan sebagai alat ukur utama Ground Control Point (GCP) pada pemetaan drone atau fotogrametri yang membutuhkan akurasi tinggi. Meskipun GPS handle dapat merekam koordinat, tingkat ketelitiannya hanya dalam hitungan meter (rendah), sedangkan GCP memerlukan ketelitian sentimeter.

Mengapa GPS Handle Kurang Tepat untuk GCP?

• Akurasi Rendah: GPS handheld (seperti Garmin seri 64/66) menghasilkan kesalahan posisi hingga 1-5 meter, yang akan merusak hasil akurasi peta foto udara.

• Standar Pemetaan: Pengukuran GCP wajib menggunakan GPS Geodetik/GNSS (RTK/PPK) untuk mencapai ketelitian sentimeter.

Kapan GPS Handle Bisa Digunakan?

• Pemetaan Skala Kecil/Tingkat Akurasi Rendah: Jika pemetaan hanya untuk visualisasi umum dan tidak membutuhkan akurasi geometris yang ketat.

• Titik Bantu: Sebagai titik acuan awal, namun hasil foto udara tetap memerlukan koreksi manual yang intensif.

Tornadoes

Tornadoes are very complex natural disasters involving many shapes and sizes. For a tornado to be on the ground, Look for rotating dust on the ground. The funnel does ## NOT have to touch the ground to be considered a tornado.

Notable Tornadoes

The most notable tornado is the May 22, 2011 Joplin EF-5tornado because it was the deadliest tornado in over 70 years. Not even 3 days after, one of the strongest and most notable oklahoma tornadoes happened, May 24, 2011, El Reno - Piedmont EF-5

Hiking has become a popular choice for many outdoor enthusiasts. Especially since the spread of COVID in the early 2020s, hiking has gained widespread popularity. Even people who previously rarely or never went hiking began to see it as a healthy and enjoyable activity during the pandemic.

In response to this continuing trend, an idea emerged: what if we at Kaart invited the OSM contributor community in Bandung to hold a joint activity? Besides serving as a recreational gathering, the event could also become an opportunity to learn about the tagging system related to hiking trails. We first shared this idea in a limited group in Bandung, but it was enthusiastically welcomed by two YouthMappersgroups: UPI YouthMappers and UNJ YouthMappers. Despite the long distance from Jakarta, UNJ YouthMappers showed particularly strong enthusiasm.

The UNJ and UPI YouthMappers community event was successfully organized and ran very well. The program took place smoothly in a series of activities beginning with the arrival of participants from Jakarta on the evening of April 17 and ending with everyone’s departure on the morning of April 19. The number of participants nearly reached the expected target. A total of 17 participants attended, consisting of 2 representatives from Kaart, 10 members from UNJ YouthMappers, and 5 members from UPI YouthMappers.

I got into looking into maps and understanding where everything is. I’m at the point where if I’m at a location I’ve never been before, I will start looking all around me and then using my brain to put everything into OpenStreetMap. I love this website. It’s like a passion project when nothing else sounds fun. Anyway… The point of this Diary is all the changes I added to different locations around the northern parts of Minnesota and Wisconsin. Here is what I wanted to update users past and present on what changes I made.

I want to thank the community for not deleting @MidwestMapGeek’s building outline. Today, I came here to fix what is the updated version. My goal is to help Semi Drivers and anyone trying to get to this company’s site. You are amazing @MidwestMapGeek <3

• Used Bing Maps Aerial to redraw buildings

– Changes – -Deleted outline of the building -Reworked the new outline for the company -Added another outline for a building next to an existing building -Reworked the rail system so it is clear the the train goes through (underneath) the building -Reworked the road leading to the building site (TPWS) -Added the scale shack that the site has -Finally added a “point” for anyone that is going to TPWS -hours, website, and location are added // note: the address that was given to the company is technically another access point to get inside but from what I heard, you can’t access from there and have to go underneath the bridge near Graymount

– Changeset Number: 182447332 –

Generally speaking, Lifecycle Prefixes mean that when something is no longer in use, a tag such as amenity gets changed to disused:amenity. That should be straightforward, but sometimes disused=yes creeps in.

This example overpass query for nwr["amenity"="fast_food"]["disused"="yes"]({{bbox}}) finds a couple of examples. In these cases we can have a look at the tag history and (as seen in the picture at the top) notice that the FHRS ID changed recently, and the disused=yes actually corresponded to the name of a different business on the same site (in fact that that one has the full set of such tags: ["amenity"="fast_food"], ["disused:amenity"="fast_food"] (which don’t make sense together) and ["disused"="yes"]. In these cases you can often look through the tag history and see what the current status is supposed to be; if the last changeset comment was “this has now closed” it’s fairly obvious.

Hari Perempuan Internasional diperingati pada 8 Maret tiap tahunnya. Pada peringatan ini pula, banyak hal yang perlu direfleksikan terkait pemenuhan hak-hak perempuan dan kesetaraan gender. Salah satunya, apakah fasilitas umum di perkotaan sudah ramah manusia, khususnya perempuan?

Sejak Maret 2026, saya mengikuti kampanye Jalanin Aja Dulu (JAD) yang diselenggarakan oleh lakunakota di Cekungan Bandung. Pada kampanye tersebut, partisipan didorong untuk berjalan kaki sejauh 2,5 km setiap harinya untuk melatih budaya mobilitas dengan berjalan kaki. Saya memanfaatkan momen ini untuk memetakan dan menilai kondisi infrastruktur pejalan kaki yang saya lalui ke OpenStreetMap (OSM).

Metode

Pemetaan saya lakukan sambil berjalan kaki dengan pace antara 9’00” (berarti 9 menit per kilometer) hingga 20’00”, rentang pace yang ditetapkan dalam kampanye JAD. Saya menggunakan aplikasi StreetComplete untuk mendata banyak objek, seperti keberadaan trotoar, penerangan, menambahkan fasilitas umum, dan menambahkan catatan untuk hal-hal yang kompleks. Setelah itu, saya berusaha merapikan pemetaan yang saya lakukan sebelumnya menggunakan desktop iD Editor.

Saya biasanya berjalan kaki di sekitar Jalan Dago, Kota Bandung. Terkadang saya juga berjalan kaki di tempat lain yang familiar, seperti Kota Baru Parahyangan dan Jalan Buah Batu. Tak jarang pula saya memutuskan untuk berjalan kaki di tempat-tempat yang belum pernah saya lalui, seperti Baros di Cimahi atau gang-gang sempit di tengah Kota Bandung untuk mendapatkan sensasi tersendiri. Selain itu, sebagian sesi berjalan kaki saya lakukan antara pukul 6 sore hingga 12 malam, menambah relevansi data yang saya dapat dengan ruang aman perempuan di jalan.

Welcome to my first entry in OSM.

I have been quite interested in being here every once in a while, it actually helps the fact that there’s a map that needs constant updating and can actually do something.

So far, from what I’ve done within my local city of London, Ontario, I finished up:

1. New Plaza at Fanshawe/Highbury
2. Bus routes
3. Road classification
4. Fixing of OSM notes
5. Coveted new developments at the South and West sides of the city.

Im not surprised that theres alot more for me as an individual to explore, nothing much and thats just all.
