I really wanted to participate in the State of the Map 2024 in Kenya to broaden my horizons, understand what is happening under other skies and exchange with members of other communities to draw from their experience: How they are organized and how t…


I am happy to receive the HOT Open Summit scholarship to attend the State of the Map 2024 held in Kenya. I can give a lecture on-site. But unfortunately, I got influenza and felt very ill during my trip to Kenya.

Individual trees are not “natural woods.” Someone has marked all the trees around my house as individual woods, but they are actually trees I planted, not many separate woodlands.



Come closer and lets have a jiffy conversation
Hear me out. You can only take advantage of so many things when youre a student, especially when it comes to personal and professional development.
I present to you YouthMappers!


Giving back to the community has been the focus. On 26_07_24, I had the opportunity to meet the UMaT YouthMappers chapter while attending the 5th WAIMM Students Conference (an annual 3-day conference).


On March 15th and 16th, OpenStreetMap Ghana (Sir Mawutor) and I visited UCC YouthMappers to familiarize them with how to fly a drone to map and to also map with Mapillary. It turned out to be an excellent result—a massive turnout. Appreciation to Dr.


I am grateful to YouthMappers for providing me with the knowledge and abilities that would enable me to impact and transform deprived communities and contribute to sustainable development.


Once upon a time a bunch of people decided to start collecting informative bits about stuff they‘re concerned with into a geo-referenced database. They mapped streets – hence the name of their experiment – and also PoIs. Records consist of a so-called tags, key-value pairs. In hindsight tags are differentiated into a primary tag, a.k.a. the substance/essence and a number of secondary tags, a.k.a. the attributes. There‘d be e.g. highway=secondary; name=Abbey Road.

One of those days, somebody noticed a problem: They wanted to map a so-called shared-space, where pedal cycles and pedestrians both allowed and traffic sings put up to show that intention. One solution might have been to tag a highway=cycleway;footway. Thereby turning the right hand side of the tag into a list. This looked ugly, a tag no longer would code for a 1:1 relation but a 1:n relation. Users of the data do not like that.

Some pondering later, the idea was born: Put the function/use/arbitrary detail of the mapped entity into the attributes where they can merrily coexist. foot=designated; bicycle=designated should from now on convey what previously was told by the primary tag. Only problem left: What would be the substance then? It must be something generic, something that provides as little information as possible over what the highway key already contains.

This marked the inception of highway=path as a light and unspecific shim over highway. All it says: It is probably narrow (But don‘t depend on that.) You likely will not see cars moving there. (With few exceptions.)

So they married, and everyone lived happily ever after.



A project I worked on, the Toronto Public Washroom Import recently finished up and I thought it would be interesting to do a quick lessons learned:


On Saturday, September 14, 2024, Pakistan hosted its first-ever mapathon, a collaborative event aimed at contributing to the OpenStreetMap (OSM) community.




I spent 11 nights backpacking in Glacier National Park this summer (on two separate trips), and noticed that existing mapping of the campsites is minimal.



It is definitely good knowing how to use field tools to map on specific projects.

There comes experience 😊 regardless of previous teaching on how to use these tools like ODK, Vespucci, Mapsme and others; in the field you definitely have to use your own discretion to relate and adjust to what is given to maintain your nobility at work.


I became interested in the issue of localizing the map of Ukraine into English and decided to raise it in several forum discussions (first, second, third) to delve into the nuances and find optimal approaches to filling out the tag for objects in Uk…


Last week we released Rapid v2.4, the most advanced web-based editor for OpenStreetMap. This release wraps up several months of work, includes numerous bugfixes, and a few notable features:

Well, let me share my experiences at “State of the Map 2024” in Nairobi at the University of Nairobi which I must say was like the coolest place ever for a bunch of map nerds like us to meet.


Since the beginning of June, I have been working on researching and locating the holy wells of County Kilkenny. I have more or less identified about 213 of them which are described in sources going back at least 90 years (Schools Collection etc).


The State of the Map (SotM) 2024 in Nairobi started with the most exciting YouthMappers pre-event at American Spaces. It was clear that the conference was going to be full of inspiration and action.

Last weekend was nothing short of magical. I had the incredible opportunity to attend my first ever global State of the Map conference in Nairobi, Kenya.



It’s really a difficult task penning down experiences that even I could not express physically, but all the same I will walk you through the mapping horizons – my journey through the incredible State of the Map Nairobi.


What an incredible three days at State of the Map Africa 2024 in Nairobi! From 6th to 8th September, I had the privilege of connecting with brilliant minds and diving deep into the latest trends shaping the Open Geospatial world. The conference offered a rare behind-the-scenes look at the incredible work of the OpenStreetMap Foundation and the passionate global community driving it forward.

The sessions were nothing short of insightful. From learning about JOSM and Open Route Service to exploring the latest web version of MapSwipe, there was so much to take in. Hearing from various OSM communities across the world was particularly inspiring, with MapKibera’s presentation standing out. Their work in promoting OSM to tackle different challenges in Kenya was truly remarkable—an inspiring example of how open mapping can drive real-world change.

A special thank you to HOTOSM for granting me a scholarship to attend my first-ever SoTM Global conference. This opportunity has been unforgettable, and I’m incredibly grateful for it. And of course, a huge shoutout to the organizers for putting together such an incredible three-day event. The social events were a fantastic bonus, providing even more opportunities for networking and exchanging ideas.

As this chapter closes, all I can say is Asante sana! I can’t wait to see everyone again next year in Manila for #SoTM2025!


We can improve user experience by providing verified, detailed and relevant information to OpenStreetMap. Let’s make OpenStreetMap a little bit better every day!


Now that I’ve taken a day off after the 14-hour bus trip from Nairobi to Dar es Salaam, I can finally sit and share my thoughts on State of the Map – the first time the global conference was held in Africa!!



This is a bit of an experiment on how to use this Diary thing!


9 September 2024
  • I just moved to Brooks, Alberta from Calgary.
  • After glancing at the ResultMaps page it seems like I might be the only active contributor in the area of Brooks/Newell County so that’s partly scary and partly exciting, as there’s still a lot of work to be done.
  • My first order of business will probably be figuring out why half the roads in town use an abbreviated “W” or “E” suffix as opposed to using the full word spelled out. I’ll have to work on standardizing that, although I’ll have to do some sleuthing to figure out the correct format for those.
  • I’m sure there will also be a lot of work to be done in terms of speed limits, sidewalks, stop signs, and other features that could be useful for navigation software.
  • Perhaps I’ll come back and do some editing in Calgary from time to time as well, particularly in the Taza Park area which continues to make steady construction progress.
  • I’m a busy man but love contributing to osm and hope to make some progress over the next couple of years. Thanks for reading my first diary entry~~!
