2023 in review

Now that 2023 has come to an end, it is an appropriate time to take a look back and see what has happened within the MapComplete-sphere.

2023 also marked the year that I (pietervdvn) received a grant by NlNet, meaning that I could spend a ton of time on improving MapComplete - and with success.

Looking back, a humongous amount of work happened. I’m giving a quick recap here.

User survey and other statistics

I’ve started the year with orienting myself. I ran a user survey (part 1, 2 and 3) and analyzed how mapcomplete was used. For example, there are some interesting statistics about the number of pictures created and about the reviews that were made

Lots of improvements

Most of the work of course went to programming MapComplete, which underwent a few big changes (notably the UI-framework and Mapping-library) and received numerous small improvements.

A quick recap:

Svelte (Q1)

The first big change of the year was switching to an actual frontend framework. MapComplete was written in a hand-rolled framework, which wasn’t very performant. And while I really loved it, using Svelte made the frontend more approachable for other programmers, more maintainable and faster.

Svelte was chosen partly because it works and has a large ecosystem, but also because it turns out to be conceptually similar to the previous, handrolled framework. Even better: the old framework is so similar, that they can be used together! With a few tweaks and adaptions, they were made compatible.

The big advantage of this compatibility is that it becomes possible to gently migrate. Instead of porting everything at once, component per component can be switched when the time is right. As such, there are still a few components around written in the old framework, but they are slowly getting replaced.

A bit more than a year ago I built the first version of Overpass Ultra. It was an experiment in making an Overpass client similar to overpass turbo but powered by MapLibre GL JS in order take advantage of its excellent support for large GeoJSON sources and vector styling capabilities.

Today, I’m excited to announce version 2 of Overpass Ultra which features a number of improvements over the first version, including the following:

• A new URL: overpass-ultra.us
• Configuration of the style & Overpass API server via YAML Frontmatter
• Simplified styling of the results with a partial MapLibre style
• Customization of the detail popups
• lz-string compressed queries in share URLs
• The ability to share the result as an interactive map without the “IDE” UI (not just hidden like in v1)
• A handy menu with MapLibre styles that work with Overpass Ultra

Here’s a screenshot demonstrating a styled query:

In preparation for an upcoming video, I fell into another rabbit hole, this time about village pounds/ animal pounds, whatever you want to call them. I won’t go into the tagging scheme which I came up with, but which is recorded on the wiki.

It was fairly easy in England and Wales, where plenty of photographs on Wikimedia with coordinates were provided. The coordinates weren’t always 100% correct, but the well preserved structures are easy to spot on aerial imagery. Historic England and Cadw combined also have hundreds in their databases which I only consulted to get the reference numbers, not to import locations! ~~~ The old Pound in Blundeston, Evelyn Simak / The old Pound in Blundeston ~~~

The situation in the Republic of Ireland is very different, very possibly also for historic reasons which I might go into in the video, but not here. I found 4 recorded as pre-1700 monuments and one as a post-1700 monument. I could find not a single photograph on Wikimedia.

Una delle cose che ci ha ricordato recentemente Steve Coast, il fondatore di OpenStreetMap, è che il nostro database è carente di indirizzi rispetto ad altre mappe commerciali.

Pertanto ho pensato di fare una presentazione dove spiego come funziona la numerazione civica in Italia. Illustro poi come si inserisce un indirizzo in OSM con alcuni esempi. Analizzo quali sono gli errori più comuni che si commettono e infine mostro diverse modalità di rilevamento e alcuni strumenti per il controllo della qualità dei numeri civici.

La trovate sul canale YouTube OpenStreetMap Piemonte, dove sono presenti anche altri video sul nostro progetto di mappatura preferito :-)

Dzień dobry.

29 grudnia 2023 roku na stronie Geoportalu pojawiła się informacja o aktualizacji ortofotomapy w Zwoleniu i kilku innych miastach. Jestem tym uaktualnieniem niezwykle uradowany, gdyż pozwala mi to dodać dane, których dokładność byłaby wcześniej wątpliwa, jak na przykład miejsca parkingowe, a będzie to możliwe dzięki zwiększeniu rozdzielczości zdjęć.

Problemem nowej ortofotomapy jest pora wykonania zdjęć — okres letni. Utrudni mi to mapowanie zadrzewionych okolic, gdyż korony drzew zasłaniają podłoże. W związku z tym będę zmuszony korzystać z archiwalnego podkładu (warstwa “Geoportal 2: Ortofotomapa czasowa (zdjęcie lotnicze) WMS” z filtrem ustawionym na 1 października 2022 roku) w tych miejscach.

Z początku myślałem, że uaktualniona ortofotomapa jest niegeoreferencyjna, gdyż ulice, których geometrię korygowałem, były przesunięte względem znaków poziomych — linii, które były punktem odniesienia. Po porównaniu z jeszcze starszymi zdjęciami (“Ortofotomapa czasowa…” z filtrem ustawionym na 1 listopada 2020 roku) okazało się, że to te aktualne w październiku 2022 roku były przesunięte. Współczynnik przesunięcia wyznaczyłem na (0.40; 0.05). Mimo wszystko proszę Was o opinię w tej sprawie.

Wszelkie zmiany, które będą możliwe dzięki nowej ortofotomapie, a w szczególności korekty geometrii, będę oznaczał hasztagiem #NoweOrtoZwoleń.

Z wyrazami szacunku

Nouvelle semaine sur OSM, nouvel update.

Une semaine un peu plus calme où j’ai un peu délaissé le micromapping (encore que…) pour revenir sur des choses un peu plus “importantes” comme de la correction de bâtiments et de zones diverses.

Au niveau des vidéos, c’est au 2/3 ce que l’on a cette semaine avec :

Ce mappeur OpenStreetMap se décide à modifier quelque chose dans le Bois de la Neuville - Version live de ce changeset qui est venu de cette note que je me suis finalement décidé à corriger

Améliorons Flémalle (sur OpenStreetMap) - Épisode 5 (Petit tour à Ivoz-Ramet) - Version live de ce changeset où j’ajoute quelques sentiers, modifie divers bâtiments et une rue mappée bizarrement sur Ivoz-Ramet

Améliorons Seraing (sur OpenStreetMap) - Épisode 25 (Le Zoning Industriel de la LD) - Version live de ce changeset où je modifie le parc industriel de la LD qui était gigantesque par rapport à sa véritable taille

Voilà pour cette semaine! C’était plus pépère ce coup-ci, et on verra bien ce que la semaine qui vient nous réservera.

A+

Аральское море – последнее большое черное пятно на нашей карте.

Еще раз подчеркну, что несомненное достоинства генерализованной карты в том, что на ней видно все объекты, выражающиеся в масштабе карты, а не только некоторые, как в osm-carto ).

Сейчас Аральское Море обозначено как natural=dry_lake.

Вопрос, чтобы нам с ним сделать (снова наполнить водой не предлагать) ?

Just stopping by on my way home this rainy morning and noting to myself to come back and set aside an afternoon to update “H-Town.”

• H-Town Market

I have noticed that ÖPNVKarte is not being updated since August 22 2023. Does anybody have any info about why it is not being updated

I recently had the privilege of attending the State of the Map Africa 2023 conference in Yaoundé, Cameroon. The event, focused on “Open Mapping as a Support Tool for Local Development in Africa,” provided a platform for diverse perspectives and insightful discussions over three engaging days. Representing YouthMappers from Tanzania and GeoTE-Tanzania, I actively participated in various sessions, sharing experiences and insights on harnessing open mapping for community betterment.

Mapping Trees for Climate Change Resilience. In my first session, I delved into the critical role of open mapping tools like OpenDataKit in mapping trees for climate change resilience. The discussion highlighted practical approaches to leverage these tools, emphasizing the importance of mapping initiatives in building climate-resilient communities. The power of collaborative mapping became evident as we explored strategies to enhance environmental sustainability through open mapping.

Gender Inclusion in OSM Africa. The second session focused on gender inclusion within the OpenStreetMap (OSM) community in Africa. In a lively panel discussion, we explored avenues to improve gender representation and participation. It was inspiring to share ideas with fellow panelists and conference participants, brainstorming on practical steps to foster a more inclusive OSM environment for everyone.

Building Sustainable Open Mapping Communities Across Africa. The final panel discussion, led by Mr. Innocent Maholi from OpenMap Development Tanzania, delved into the theme of building sustainable open mapping communities across Africa. Joined by panelists Ezekiel Kiariro, Nathalie Sidibe, and Severin Menard, we exchanged insights on strategies to create enduring mapping communities. Our discourse covered topics ranging from community engagement to resource mobilization, leaving us with a roadmap for nurturing vibrant and sustainable mapping ecosystems.

I hope poking fun a little is acceptable. :) Happy mapping, all!
