On November 21, 2021. I completed three intense and joyful days of virtual attendance to the State of Map Africa Conference 2021. First and foremost, I would like to express my heartfelt gratitude to the organisers for thinking outside the box and planning this successful event despite the world being stressed by the COVID-19 pandemic. Thank you to all of the organisers, volunteers, presenters, and attendees for making the event a success.

Three days for the whole virtual conference was plenty in terms of internet data; my deepest gratitude goes to the conference organisers and sponsors for awarding me and other scholarship recipients to attend. For many of us, the data scholarship was a game-changer, as internet costs are still extremely costly and unaffordable in many African countries.

Apart from bringing together GIS experts from around the world, the conference served as an important learning opportunity for all of us with an interest in GIS who, despite not being experts, have found careers using GIS and OSM tools, which we use daily to solve the most pressing social problems, particularly humanitarians issues.

This year’s conference was unique in that it included a wide range of topics and industries from which presentations were given, allowing for cross-pollination among participants from a learning perspective to collaboratively solve human problems. Furthermore, the conference was extremely beneficial to new mappers like me, as I learned about and was taught how to utilise other OSM tools that are effective in mapping through various presentations. Claire’s demonstration of Street Complete, Map Roulett, and OSMOSE was like exposing a new baby to the sun for the first time! I just finished filling Waoo!

Alongside other participants from the University of Lagos, I attended day 1 of a series of 3-hour training organized by the UN Mappers in conjunction with Key to the city YouthMappers. Severin Menard anchored the session and in the session, he gave an introduction to the OSM platform, expatiated on how the UN is making use of OSM data in her peacekeeping missions, how people can get involved and contribute to the OSM platform, HOT Task Manager, contributions of the UN Mappers over the years, mapping using ID Editor, Quality and use of OSM data, etc I really enjoyed the training session, and I am looking forward to day two tomorrow.

There are lots of ways to turn OSM editing/updating into game/quest like activities. One of them is the app “Street Complete” which is great for use “on the go”. Should be great on a bicycle perhaps.

Other notes: MapwithAI is working with OSM to quickly turn imagery into editable features. Unfortunately in a place like HD this will probably result in lots of false roads, as I found with Google Maps in Hubli - ending up next to the airport wall. https://mapwith.ai/#13/-7.95604/31.59543/0/55

Are there local mapping groups in the Hubli Dharwad area?

China mappers complain about there are many students mapping around Zhongnan University, which seems assigned by school teachers, but lack of QA process after students had done their mapping tasks. These kinds of issues are faced by the community someday, whatever the community decides to fix it, or just remove the low-quality stuff, it is all OK. And in an extreme case, the community could ask the Data Working Group for help, by banning accounts that keep editing and adding low-quality data, getting some precious time for the community members to fix the data.

As a Taiwanese mapper, Taiwan experience of dealing with school assigned tasks from teachers, leaving changeset comments are quite useless, few will response to the comments. Directly fixing the error or low-quality data is faster, and reseach where do these change come from? If you do not want to spend your time of fixing error or improving the data quality, then just delete the stuff is OK. If the damage so big and no response from the mapper, can’t be handle by community, then the Data Working Group can step in and no further damage.

Recenlty most serve incident in Taiwan is Micron editing group. They use HOT Task Manager to draw buildings in Changhua and Yunlin. They drew so many problem buildings, that can’t be handle by the community, so the HOT ask Data Working Group to step in and delete all the buildings by Micron editng group.

Another incidents like editing group from shcool of Changhua, which one could not trace which school they belong to. And another incident like some mappers adding psychological medical clinic, which using coordinate geocoding by Google Maps, there is a data license issue.

Action for Economic Reforms (AER) is a Philippine non-government organization engaged in research and advocacy. It conducts policy analysis and advocacy on macroeconomic reforms, universal health care, industrial policy, freedom of information, among others, and key issues of the day.

Coalescing Organizations towards Locally Led Actions to Boost Development (COLLABDev) is a partnership initiative of AER and the United States Agency for International Development (USAID) to promote human-centered, data-driven development in the Philippines. One of the main components of the COLLABDev project is to promote the development of existing open geospatial communities and data, especially in the 14 sites from the six provinces covered.

On October 8, 2021, the University of Science and Technology of Southern Philippines (USTP) as one of the partner State Universities and Colleges (SUCs) in Mindanao, signed the Memorandum of Agreement (MOA) to assist Local Government Units (LGUs) in the drive to use data to craft policies and to implement projects and programs of the COLLABDev Project.

State of the Map - Eastvale

  1. Roads - Currently they are mapped and seem to be fairly accurate
  2. Buildings and Businesses - Currently building and businesses are mostly mapped
  3. Residential Housing - Eastvale is lacking addresses, residential housing areas

Currently I’m dedicating my time to add address and residential housing to OSM as Eastvale is heavily lacking basic navigation

27 New Houses and Addresses Mapped!

A few weeks ago I was told by a Lorry driving friend that a new Truck only service station had opened nearby. I was quite surprised as Lorry driving infrastructure is normally not the best in the UK, and I was quite surprised to see a brand new facility.

Based on dash-cam footage they showed me and Bing aerial images, I attempted to get as much information as possible.

Whilst writing my previous post on Welsh Heaths I discovered that a hill on the Llŷn Peninsula shown as heath in the Phase 1 survey has no landcover mapping on OSM. I walked up Myndydd Rhiw in 2008, just before I started contributing to OSM – so I failed to take enough photos. The weather was not very good that day so I’d opted for a car journey to visit locations on Llŷn rather than brave the rain in Snowdonia. Rhiw was the only place which wasn’t chosen because of personal associations: not only had we holidayed there several times during my childhood, but my great-grandmother’s family come from Llŷn,

Today I am completing two years as an OpenStreetMap contributor so to celebrate I will make a brief retrospective about this last year. 2021 was not an easy year for the Brazilians with the negligence of the government we reached the mark of 600k dead by Covid-19, besides the return of hunger and high inflation but as Belquior would say I can consider myself lucky, editing in OSM gave me strength to endure many things, mapping this year was like a therapy. This year I also had the opportunity to meet incredible projects and people!

Statics

Some numbers:

  • 22,503 edits
  • 170,425 buildings mapped
  • 15.202 Km of roads mapped
  • 9.926 Points of interest mapped
  • 4,323 Km of rivers mapped

What happened to Mapeia.Space?

It is a complicated story, first we had to change after DAMN totally changed the way we work and as Hot TM seemed to have matured in the performance issue so we decided to switch to Tasking Manager what happened is that we had to start from scratch again… we had a problem with our hosting at the same time I received the invitation to use HOT Tasking Manager (Thanks Wille and Vitor George for this opportunity) since then there were 7 published projects. Then there was no reason to maintain an own instance of Tasking Manager so the mapeia.space was closed although I tried to create an organization around Mapeia to promote mapping which also didn’t work but in the end it ended up giving as a fruit of research on the use of online maps.

I’m undertaking a bit of a project in Burnie, a city in the state of Tasmania in Australia, and thought that I should leave a more public note about what I’m doing and the reasoning behind it. Don’t expect anything particularly entertaining from this entry. The short version: a recent import of official suburb boundary data can be used to accurately offset aerial imagery, which can in turn be used to consistently align existing mapped items across the city.


While there are other mappers in the area, and I was most active in OSM mapping several years back, I’m responsible for a decent amount of data in the Burnie area. My process was pretty straightforward: drive to a new area, survey on foot, record GPS traces as I went. Back home I would upload the address data and anything else that needed updating and trace buildings from imagery. The best-quality imagery at the time was Bing, which was fairly average resolution and not always well-aligned, so I’d align the map to my GPS traces or publicly uploaded ones, depending on subjective recording quality. While this was in good faith, it meant that each little area I’d surveyed tended to have slightly different offsets, with no way for me to tell if any were correct. It’s minor, but many of the buildings I traced are also poorly outlined, though the older imagery probably limited how well I could do at the time.

Having resumed OSM mapping recently (after moving house - what better motivation than having a new neighbourhood to explore?) nobody had done much to improve this issue. Not surprising; it’s not the most populated area, things were good enough for routing purposes, and there was plenty that still wasn’t mapped at all. But it bothered me, and I noticed a new feature that made it much easier to resolve.

Welcoming new mappers

TLDR: It’s now super easy to welcome new mappers in your country or region. Just post an issue at the Welcome tool repository, and we’ll set you up. New mappers will be listed and in a few clicks you can check their work and welcome them with a localized welcome message. You can share the workload, as it will be clear who is and who hasn’t been contacted. Try it out at https://welcome.osm.be/ (don’t forget to connect your OSM account). Instructions on how to request your region available here.

About the tool

Back when we started doing real life meetings in Belgium, one of the first frustrations was how hard it was to get in touch with mappers. How do you let mappers know there’s a group of locals who are eager to get to know them? And how do we offer a helping hand to new mappers?

Of course, the first thing you think about is automating, plugging in to the global OSM software. But that software evolves slowly and you’d have to come up with a solution that works worldwide from the start.

So we decided to go for a simple solution: Belgian mapper M!dgard built a simple tool in PHP around Pascal Neis’s RSS feed of new mappers. M!dgard never stopped hating the ugly coding, but it did do the job for several years - with Jakka doing most of the welcoming work.

Don’t expect welcoming new mappers to be very rewarding. Most new mappers are never going to stick around, so just a few percent will ever answer you. Statistically speaking, there doesn’t seem to be an impact on mapper retention either. But we always felt that it does help people to find their way in the documentation and in the communication channels. Not in the least, we used the tool to monitor the edits of new mappers. That helped us spot errors as well as occasional vandalism.

Hello all,

I recently picked up mapping with the river modernization folks, and one of the first things I wanted to do was to speed up the rate at which I could modernize rivers.

When I was in 5th Grade, I bought a PlayStation 3 from a friend that I used to have sleepovers and play on together for 100 USD. it came with 2 controllers and I’ve since used them to play games, mostly on my computer.

Recently, I stumbled upon this program, that recognized my controller and let me map keybinds to it. I toyed around with it and ended up making a basic configuration to speed up my most common key combinations.

My initial control scheme

To complete any given riverbank with no other tags on the to-do list, I would simply press O, then move the right joystick up and to the left to add the desired tags natural=water and water=river, then to the right to mark the object complete.

If I ever messed up any part of the process, I could simply move the left joystick down and to the left to undo the change.

I asked myself, how to map the new built SPAR (Supermarket), which is mostly overgrown. Below is the concept picture of the building: concept of a supermarket It pretty much looks like this in reallife and you can (can’t) see, that there is a field, respectively a meadow on the roof. Mapping the building as “underground” wouldn’t make much sense to me, but “overground” does neither. Maybe I should just map the Supermarked as a single point (like it is right now, temporarily)?

What would you suggest?

Simple uBlox F9P howto

I got a question about specific usage of the F9P from zero to hero, so, here’s some summary from the beginning.

It is simple and almost hassle-free.

I got my board from uBlox directly but I guess it works the same with all the F9P boards. The board came with an external antenna (if you don’t have that you definitely have to find a good one, makes a lot of difference), and an USB-B cable for power.

As for the hardware, you need:

  • power source; I am using a 10 Ah powerbank which is enough for 10+ hours (probably even more)
  • a box, to put the board into, and preferably stable within, either by screws or some foamy stuff. The connectors are said to be sensitive, so try to find a way to relieve any stress on them.
  • for the external antenna you should find a way to keep it at the top seeing the satellites. My antenna has a strong magnet and I got a metal plate so I usually put the antenna outside of the top of my backpack sticking to the metal plate inside.
  • You need a mobile phone with bluetooth. Preferably Android, since I can’t help with iAmrich models. (Theoretically you could use a laptop but, uh.)

The board does not really need any setup, but there are freely available windows® programs turning the internal knobs. Since the board came with Bluetooth enabled I didn’t need to fiddle with settings (but I’m a fiddly type, so I have, but you don’t have to).

For the phone you need an app which can

  • connect to the board by bluetooth
  • able to retrieve an NTRIP stream from the network (about that later)
  • can send the stream to the board
  • can retrieve the NMEA log from the board
  • and preferably can provide mock locations for the phone.

There are two free apps available at the moment I am aware of:
