I’m a skilled cartographer and GIS professional with expertise in mapping, spatial analysis, and information visualization using various software, including ArcGIS, QGIS, AutoCAD, ACAD, and OpenStreetMap. I create informative maps, conduct network analysis, and perform connectivity studies to drive insights and inform decision-making, leveraging my skills in GIS mapping, spatial analysis, and cartography to deliver high-quality solutions and contribute to projects that require spatial analysis, mapping, and data visualization.

Cartographers in Uganda’s National Water and Sewerage Corporation would play a vital role in water resource management by creating maps of water infrastructure, such as pipes and treatment plants, and mapping water sources like rivers and lakes. They would also identify areas prone to flooding, monitor water quality, and inform infrastructure planning using geospatial data. By providing accurate spatial data, cartographers would enhance planning, efficiency, and decision-making, working closely with engineers, hydrologists, and environmental scientists to ensure effective water resource management and infrastructure development.

Streetcars Rule

I’m trying to make a map of a streetcar line that I think ought to be built.

Little did I know when I first started my job in Antarctica that I’d become obsessed with editing OpenStreetMap during my empty hours at work. While I made an account back in 2019, that was simply to add a missing sidewalk from my mission in India that bothered me. Last month, I was playing around with some maps, seeing how different engines would interpret a cycle route I frequently took back home, and I noticed the trail was laid out with a bit of jank. I decided I had an account and the fix would be easy, so I went ahead and did it. I then saw the sidewalk options, and started playing with infilling the sidewalks around the route.

That was a mistake.

I have since spent hours adding sidewalks everywhere I’ve been. As I learned the tools and improved my methods, I started looking at other options. Street lamps, lowered curbs with tactile paving, and power poles were next. I started looking into other ways to contribute and installed Street Complete on my phone. I saw my office trailer wasn’t listed on the map at McMurdo, so I used OSMTracker for Android to map it out (Turns out, my phones GPS combined with the poor signal so far south makes things a bit more challenging). I then started using it to map all the infrastructure I could reach. I spent 2 hours on one of my few 2-day weekends down here out in -10F weather mapping out the power poles and lines connecting them.

Needless to say, this has become a bit of an obsession, but I suppose if I’m going to have that, I can at least use it to do some good in the world, no matter how small. Now if you’ll excuse me, I’ve got some suburban sprawl to map out. Those sidewalks aren’t going to add themselves!

Today, I had a good time at the national office and Mapathon center of Unique Mappers Network-the OpenStreetMap Nigeria Community NGO (https://www.openstreetmap.org/#map=18/4.899962/6.

Today 12th May 2025, I got to the place i’m suppose to do my IT, [INDUSTRIAL TRAINING], As at 10am in the morning when asked to come. I met 2 other people David and Angle, they welcomed me while i waited for the National Coordinator DR VICTOR .N. SUNDAY of unique mapper. After was, the National Coordinator DR Victor sunday came in, with out wasting much time, another person enter named chika i guess so, so he introduced OpenStreetMap to all of us that were there together. He said a lot of things about the OpenStreetMap, As what we use in carrying out mapping and it’s also free, like a volunteer thing. It was exciting to have DR Victor Sunday, the coordinator teach and talk about the OpenStreetMap, Me been introduce to OpenStreetMap, its not my first time but i was able to get a clear picture of what an OpenStreetMap was all about, which it was intresting, Now i can say i know how to map a building. yoooo!!! With everything that went on, everyone had to practice for themselves on learning how to do the mapping there self, which was cool and right now we are done with the classes on mapping as at 1:56PM, Everyone is expected to sign up with OpenStreetMap and map out at least 10 buildings showing you have learnt something for the day, hmmm its really a lot today though, i’m happy to have come here today and i’m ready for it. This is my passion, This is my dream,for the next six [6] months i will be here, i hope to achieve a lot, and thats it.

Secure everyday maps

The State of the Map Call for Proposals deadline is approaching fast, and I know that feeling - staring at a blank page, wondering if your OSM experience is conference-worthy.

Hello all, to start with, Ive always been interested in open software and collaborative projects. I actually made an OSM account way back in 2012, as you can see on the HDYC website. I cant really remember why I made it to be honest.

Mapping the days

We know OpenStreetMap is one of the most powerful and collaborative geospatial databases in the world. It relies on contributions from everyday users, developers, humanitarian workers, and mapping enthusiasts to keep data accurate and up to date.
But like any open data project, OSM faces issues. And understanding the types of issues we encounter is essential to maintaining map quality. One simple and effective way to think about OSM data problems is, to divide them into two broad categories:

1. Existing Issues: Errors in the Map

These are problems that exist within the current OSM data. The features are already mapped, but something about them is incorrect, inconsistent, or outdated.

Common examples:

• Incorrect tags: A residential road tagged as a motorway.
• Geometry errors: Buildings that are misaligned, roads that don’t connect properly, or rivers overlapping with buildings.
• Outdated features: A shop that closed years ago but still shows up on the map.
• Inconsistencies: Using different tags for the same type of feature in nearby areas (amenity=school vs. building=school).

2. Non-Existing Issues: Missing from the Map

These are features or data that should be on the map but are completely absent. The problem here is not about fixing what’s wrong, it’s about recognizing what’s not there at all.

Common examples:

• Unmapped buildings visible in satellite imagery.
• New roads or paths that haven’t been digitized.
• Missing POIs like schools, hospitals, or shops.
• Lack of metadata such as opening hours, accessibility info, or addresses.

---

Why This Distinction Matters

Thinking in terms of “existing” vs. “non-existing” issues helps:

• Prioritize tasks: Fixing vs. adding require different skills and time.
• Guide new mappers: Beginners can focus on adding missing data, while experienced users fix complex issues.
• Organize mapping campaigns: Humanitarian or local efforts can be tailored to the type of issue in a region.
• Improve data validation: Tools like OSMCha, or Osmose focus on identifying existing issues, while others like MapSwipe or HOT Tasking Manager target missing data.

It was a beautiful day for a hike, so I set out early at 8am sharp. I headed back to Ely, trekked some of the trails in Plymouth Great Wood, cut through the park in St Fagans, passed through Western Cemetery, then over to the iron-age hillfort in Ca…

Mapping & Hiking: how to collect open data while having fun

How complete are addresses in OpenStreetMap in Belgium? After several status these previous years (see September 2022, in May 2023, and in May 2024, November 24), I finally adapt the process to analyse addresses completeness for all Belgium!

Cartographie OSM des dommages du bâti à Mayotte après Chido

OpenStreetMap Indonesia, in partnership with TomTom, organised a Community Mapping Party at GoWork Plaza Indonesia in Jakarta on Saturday, 26 April 2025.

I have added a pin for my house, which is at 38150 N Vista Dr in Livonia! From here, I have encountered tons of wildlife, including fish, and generally been treated pretty well. There are parks nearby, riparian zones, old-growth forests, modern civilization including a hotel with swimming pool, and plenty of transportation opportunities. You can even walk here. There’s water, a lawn, and interesting people here. My basement is the coolest!

This blog post is part of a series of blog posts about the new OSM file format OMA. This is the last post. At the end of the article youll find links to the other blog entries.

Hello, I have completed work for the first part of the project. Central Wilson and the length of Fish Creek road have reached a point where roads, driveways, structures, and water features have been thoroughly digitized. Check it out and let me know what you think! :) I am sure there are some things I’ve overlooked and maybe some mistakes in these areas. However, given that they are seeing a fair amount of development, I will likely be returning to them soon to update and double check for possible mistakes. I do have a question for you all out there, more experienced than me. I have come to despise the existing residential-landuse areas in Wilson. They are a mess and seem to be quite outdated. I would be more than willing to fix or make new ones, but I don’t know if there is a specific way to go about that kind of thing. Do they need to be based on any administrative boundaries or are they a more arbitrary area? As for what’s next in the project, I am moving east to the Stilson area to fill in completely missing neighborhoods, improve roads, add water features, etc. I will give the next update once completed.

The relationship between municipalities and populated places in the United States is often not obvious, especially in New England due to the naming of their local governments. Naming them towns has blurred the distinction of populated places and municipal governments, when in reality, a clear distinction can be made between the two.

First, let’s look at the things almost everyone should agree with. Nodes tagged with a “place” tag can be referred to as “populated places”, or named concentrations of people. The GNIS definition of a populated place says it best: “Place or area with clustered or scattered buildings and a permanent human population (city, settlement, town, village). A populated place is usually not incorporated and by definition has no legal boundaries. However, a populated place may [correspond with a] “civil” [entity], the legal boundaries of which may or may not coincide with the perceived populated place. Distinct from Census [places] and Civil [entities].” In other words, nodes with a place tag refer to a human settlement, NOT to a municipality. They are the places one might see on a green direction sign while on the road. The exception to this is if the municipal boundary corresponds to the extent of the populated place, which is the norm in most states.

However, in New England, town boundaries are usually formed out of straight lines and rivers, not with the intention of delineating the boundary of a populated place. Therefore, even if a town shares a name with a populated place within its borders, the populated place will not always fill the entire municipality, leaving room for other populated places to fill the rural areas. Some municipalities even lack a populated place with the same name as it. This leads to there being no 1:1 correspondence between municipalities and populated places in New England.

Before we explore some real-world examples, I would like to categorize each scenario. The possible cases for a municipality are: 1. A municipal boundary corresponds directly to a populated place’s boundary (most common in urbanized areas); 2. A municipality contains a populated place with the same name, but that place is not coterminous with the municipality; 3. A municipality does not contain a populated place with the same name. 4. A populated place is not within a municipality of the same name.

An example of scenario 1 is Nashua, New Hampshire. Nashua is the second-most populous city in New Hampshire, and it has grown to fill the entirety of its city limits, houses filling every corner of the city. Another example of scenario 1 is Woonsocket, Rhode Island, an important city of the state. Unlike many municipalities in New England, Woonsocket’s boundaries appear to have been drawn around the physical limits of the populated place. In the case of Nashua and Woonsocket, they should be tagged as place=city due to their regional significance; however, smaller category 1 places should be tagged as such. Any other populated place within the municipality should be a place=suburb/quarter/neighborhood.

An example of scenario 2 is the Town of Voluntown, Connecticut. Voluntown does happen to correspond to a populated place located in the west of the Town. However, it makes up only a small section of the municipality. Another example of scenario 2 is Lincoln, Vermont. The populated place of Lincoln is tiny and centered around a Methodist church near the geographical center of the town. The populated place of Lincoln is also represented by a census-designated place of the same name. Much of the town is rural wilderness, putting it soundly in category 2. Each populated place within the town should be tagged as place=town/village/hamlet, depending on the significance and available amenities.

An example of scenario 3 is Griswold, Connecticut. There are a few populated places within the Town of Griswold, including Glasgo, Hopeville, and Pachaug, but none are actually called Griswold. Their town hall is located within the Borough of Jewett City, a category 1 place. Griswold should not receive a place node since there are no populated places known as Griswold. The municipal boundary shall suffice.

One example of scenario 4 is Shelburne Falls, Massachusetts. Shelburne Falls is a village within the Town of Shelburne. Shelburne Falls is unique in that it is much larger than the Town’s center. However, this does not distinguish it from other category 4 populated places. It should still be tagged as place=village (due to its size), not as a suburb or a neighborhood. It is a distinct community from the tiny hamlet of Shelburne. Another example is Shin Pond, Maine, located in the Town of Mount Chase. Shin Pond, a community distinct from the Mount Chase populated place, should be mapped as a place=village or place=hamlet.

In summary, not every New England town corresponds 1:1 with a populated place. Just like other states, the populated places of New England are not dispersed perfectly evenly; some variation can be seen. Therefore, we should conform our tagging schemes to how our communities developed naturally, not by how they are governed. And most of all, we should not fabricate populated places on the map.

Is there anyone here? Lol

Would be cool to take a state on and edit for the next 10-20 years. This project is cool. I love the idea of a free map for everyone and anyone to edit.
