Following mobilization of volunteers and OSm newbies at Benue State University to kick-start a new chapter and team of Unique Mappers to drive Map Nigeria Mapathon project and the Makurdi on going project .We had a training for newbies. More than 20 newbies has been mobilized and signed up to OSM. These include William Hundu, the Team Coordinator, Lucas, Glory,Shater ,Jacob an others After the virtual meeting ,I hope to travel to Makurdi for in-person training and MOU with the University and Unique Mappers Network,Nigeria

Also .we are planning for stakeholders workshop for data use cases

Hello fellow mappers.

My name is Ayame Otsuki, and I am honored to be nominated as a 2025 voting member of the Humanitarian OpenStreetMap Team (HOT).

I’m based in Japan, and I’ve been engaging in mapping activities as a member of NPO Crisis Mappers Japan since 2015, and I set up a youth team within this community.This February, I gave a presentation about “20years Journey of OpenStreetMap” at State of the Map Japan. Sorry for it’s Japanese

I currently work as a data scientist and analyst at a Japanese telecom company.

What does HOT mean to me?

To me, HOT is a community of people who believe in the power of open data and try to provide humanitarian support across borders. HOT is the one that taught me that a single computer can help some people all over the world.

How did I become involved in HOT?

I first became involved with HOT when I participated in a crisis mapping activity for the 2015 Nepal earthquake, which was organized by Professor Taichi Furuhashi at university. I got to engage in mapping activities since then, and developed an efficient tool (BCr.map) for drawing buildings (rectangles) as my university graduation research project in 2019.

Why do I want to be a voting member?

I would like to be more actively involved in HOT community by becoming a voting member. And also, I want to serve a statistical and objective perspective in HOT’s strategy and governance as a data analysis expert.

My involvement in HOT, mapping, and/or humanitarian response:

I’ve been engaging in mapping activities by using HOT’s tool for 10 years and expand the Crisis Mappers Japan community. I’m also a drone pilot of a Japanese disaster drone rescue team and taught how to operate a drone to local kids.

My most important responsibility as a voting member:

Hi Everyone!

My name is Anqi Xu and I’m currently based in Vancouver Canada:) I am a geocoding (and open source) newbie and I’m super honoured to be working on the Transliteration of Search Results project this summer and am really excited to hone my coding skills and learn more about OpenStreetMap! The link to my proposal can be found here. Feedback is welcome (and much appreciated)!

A bit about me; I’m going to graduate (hopefully) from UBC Engineering Physics later this month. I’ve done a variety of internships in many different industries, including quantitative finance, particle physics research, and semiconductor manufacturing! I’m a big believer in lifelong learning, and I really enjoy board games, crosswords, and silly logic games! I’m also a big fan of travelling and visiting new places, and have recently started to document some of that on Youtube.

Thanks for having me and I’m looking forward to meeting everyon!

So today I get to talk other mappers. and I get to know how they map the challenges the have like; 1. Unavailability of internet connection 2. lack of Devices or tools for mapping etc. After the challenges we get to talk about solutions where we find a solution about getting a router and recharging it so the mappers in a particular area can come together and use it for mapping. And we still Provide systems for those without system to use for mapping till they get their own. I really learned alot from their experiences then by the end of this week i will be able to use JOSM cause we are suppose to be taught by a more experienced mapper. I really enjoy mapping and i still plan to meet mappers around the world so we can share our ideas together

Nisreen Mahmoud, 2025 HOT Voting Member Nominee

Hello fellow mappers, My name is Nisreen Mahmoud, and I am a GIS and remote sensing expert. I am originally from Sudan, and I currently reside in Egypt. I currently serve as the Supervisor of Surveying, GIS, and Remote Sensing Group in the Khartoum Reconstruction Initiative (KRI). In addition to my supervisory role, I also lead OSM Sudan. Previously, I served as the East African zone coordinator for African Women in GIS (AWiGIS) in 2023. Today, I’m also a proud mentee in the Women+ in Geospatial Mentorship Programme, where I continue growing my leadership and technical outreach abilities. I am passionate about creating spaces where emerging mappers, especially women, African mappers, and those from conflict-affected areas, are able to feel seen, heard, and empowered to lead. I am honored to have been nominated as a 2025 Voting Member of the Humanitarian OpenStreetMap Team (HOT). As someone whose life and work are deeply rooted in both humanitarian response and geospatial science, this opportunity feels especially meaningful. I am pleased to introduce myself and articulate my aspirations to contribute to HOT’s mission.

What Does HOT Mean to Me? HOT represents the fusion of community, technology, and humanitarian action. It’s a space where open data becomes a lifeline—used to empower communities, support climate resilience, and respond to crises. For me, HOT is about building bridges between people and tools, between local knowledge and global support.

So, I got invited to speak at a certain OSM community’s monthly online talk.

Nice, right?

Well, there’s just one problem: I have absolutely no idea what to talk about.

Sure, I could present one of my recent OSM-related programming projects, or share updates on what I’ve been mapping over the past few weeks. Maybe even talk about my personal hopes and dreams for the OpenStreetMap movement—or write a more reflective essay on the movement’s progress and future.

The deadline is still a ways off, so while I mull over the best topic, I figured I’d start with something simple. Something fresh. Something that literally popped into my head minutes before writing this post.

It all starts with a very basic question:

“Who is the most active mapper in city X?”


Why This Question Matters

If answered properly, this question could open the door to a whole series of follow-ups:

  • Are they local, organic contributors—not affiliated with a distant organized mapping group but actual residents who have lived in the city for a long time?
  • What does their OSM diary look like?
  • What have they been mapping lately?
  • Are they part of a local mapping group?
  • Have they initiated any projects in the past—or are they running one now?
  • Can we collaborate with them? Reach out?

Active mappers are often the “local ambassadors” of OSM. They can be our primary point of contact for a specific area—people who know the region inside out. They might even offer local tips, points of interest, or become a valuable reference for others mapping or traveling to the same area. Sometimes, these mappers even maintain detailed wiki pages for their city—outlining points of interest, transit routes, historical context, recent updates, or even personal anecdotes.


Meet Your Mappers

Hello everyone!

I’m Ayush Dhar Dubey, a 2nd-year undergraduate student at Indian Institute of Technology Roorkee, pursuing my major in Civil Engineering. While my academic roots lie mostly in reinforced concrete and structural design…software development and open-source have become equally foundational to how I think about solving real-world problems.

I’m thrilled to share that I’ve been selected for Google Summer of Code 2025 as a student developer with OpenStreetMap (OSM). My project, under the mentorship of Lonvia and Tordanik, is titled “Modernize the 3D Model Repository (3DMR)”.

What is 3DMR and Why Does it Matter?

The 3D Model Repository (3DMR) is an online platform that allows contributors to upload openly licensed 3D models and link them to OpenStreetMap features. Tools like OSM2World can then render realistic 3D views of real-world locations using this data.
