In May 2023, I discovered the existence of two websites : “The Skyscraper Center” and “Skyscraper Page”, presenting skyscrapers from all over the world and especially… skyscrapers from Pyongyang!

I took this opportunity to enrich several free projects on which I’m active: Wikidata with the creation of the elements in the first instance, combined with images from Wikimedia Commons in the second instance, to place them and link them with the OpenStreetMap data in the final instance!

Creating the skyscrapers in Wikidata

Wikidata is a database that can be very useful for the OSM project. In my case, it was very useful for tracking each skyscraper.

And it’s very well suited to adding all the skyscrapers that existed in The Skyscraper Center and Skyscraper Page for Pyongyang city.

Wikidata has a number of “properties” (PXXX) which can be used to provide a whole range of information:

• where each building is located (P625)
• when they were built (P571)
• their height (P2048)
• the number of floors (P1101), etc…

TLDR: No.

Very long version: Maybe

I was inspired by Feye Andal recent post, so I’m telling my experience and providing a workflow to those who face the same problem.

Background

Recently I was looking to buy an affordable 360 camera to capture street-level imagery and obtain the processed elements that Mapillary provides (traffic signs and other points, via AI). I wanted it to use on my PhD research and of course, contribute to the OSM community and map data. The main recommendation is the now a bit old GoPro Max 360. The product is solid, and very easy to connect to Mapillary.

This is my first OSM contribution: THPRD in cooperation with Arbor Lakes HOA, LLC and Finley Woods/Noyes Development have created a new Waterhouse Trail segment with easement over Finley Woods and Arbor Lakes property. I added the new trail segment to the map after recording a GPX on my phone walking the trail. I hope I did it right!

Personal notes about potential mapping of the Palenque archeological site from archeological GIS data.

Source

Edwin L. Barnhart. 2001. The Palenque Mapping Project, 1998 - 2000 Final Report

Questions

• Permission to use the data, no licence specified -> get in touch with author
• What to map in OSM? Only visitable areas? Major buildings (ie. Templo Escondido)? Waterways? All site (lots of buildings, does it belong to OSM)? A staged approach is necessary
• Is there any local community / interest groups to get in touch with?
• The data looks like it’s of good quality but dates from 2001. Any updated dataset?
• 3D mapping of certain buildings?
• Source for naming? Limited on-the-ground names, multiple naming schemes (the source paper claims to be overcoming this in a sensible way, is it still up to date, accepted by the archeology community?) English translation for certain objects
• Any prior work in OSM for this site or similar archeological site?

Problems

• Data in DWF format, how to import in JOSM

TODO

• Review OSM data import guidelines
• Add onsite map pictures (seems to be from the same data source)

Maplibre and Protomaps are a match made in heaven! Together they are democratizing vector maps! There’s no better time to get involved than now; let me set the scene first.

Maplibre SDK with Protomaps vector tiles, map at an angle with a video source playing drone footage video overlayed; data attribution (c) OpenStreetMaps and contributors

Maplibre is the open source map SDK forked from mapbox-gl-js when Mapbox changed their license and moved away from open source in 2020. Maplibre packages up around seven years of state of the art map renderer development and is best in class in terms of map rendering and styling vector tiles.

Protomaps is a relatively new project and it’s fundamentally changing how vector maps are distributed. Protomaps can package up the whole world into a single .pmtiles files of around 100 GB. Static hosting this single file gets us global vector tiles! Magic!

AUTOMATIZAÇÃO DO PROCESSO DE IMPORTAÇÃO E CONFLAÇÃO MASSIVA NO OPENSTREETMAP

O Baceliño, con preciosas vistas do outro lado do pobo, parte do barrio do Coutiño (ollo a estes nomes e ó cerca que están, como sinalei na foto anterior, e canto diminutivo utilizado). Nesta zona situou o PXOM do concello de Cortegada unha “casa grande”. Por desgraza, denomínana como “do Cazapedo”, cando tan topónimo inda se atopa a uns cantos metros de distancia. Mal menor sería dicirlle “do Coutiño”.

Así queda descrita na ficha patrimonial: “Edificio de planta rectangular de grandes dimensións, muros portantes de perpiaños/cachotería de granito á vista, dúas alturas e cuberta a catro augas con cubrición de tella plana. En contraposición a fachada posterior, lisa e sen vans na planta terrea, na principal destaca a presenza dun corredor e nas laterais balcóns voados con varandas de ferro”.

O código do elemento é o 6-15, a localización en plano é EX-03 e a clasificación do solo denomínase Solo de Núcleo Rural Histórico.

A Canliña. Unha zona pequena e alta situada entre A Tella e O Coutiño, cunha casa grande como referencia, lindante con terreos de escasa lonxitude e dispostos en sucalcos, con muros realizados en pedra e escaleiras integradas neles.

Ei van unhas liñas de José R. Veiga Formigo, que alí vivíu:

“Mis recuerdos son de la infancia y adolescencia. Era la casa de mis abuelos maternos y de las reuniones familiares inolvidables. Su situación es antes de llegar a Fonte da tella, a mano izquierda en un alto. Desde su balcón yo me sentaba a leer las aventuras del Capitán Trueno, y más adelante, y con otra edad, Los Gozos y las Sombras etc..”

This diary is a collaboration between Ibrahim and Nombuso.

As part of the open humanitarian mapping community working group mentorship programme, all mentees were asked to produce a legacy project. As Nombuso wanted to work on data that would benefit women and girls in Eswatini and Ibrahim wanted to improve his technical skills, we decided to collaborate on one joint project.

Choosing eSwatini health data as the focus of our project.

We know that good quality health data is an asset for women and girls (to be able to find where there are services, when facilities are open and how far they might be away). So we decided to investigate how well OpenStreetMap provided information on these services for map users. First, we tried to download and consolidate all of the health data in OSM (amenity=hospital, clinic and doctors).

Open Geospatial Data for Disaster Recovery/Response

Fiji is a small island developing state and has been and continues to be severely affected by the obvious impacts of climate change, i.e. increase in sea level causing coastal erosion, water shortages due to salt water intrusion and the more apparent impact of the increased occurrence of extreme weather events such as tropical cyclones, storms, floods, droughts etc. Having personally experienced some of the worst tropical cyclones that has ever made landfall in Fiji, the project has been developed in light of the after effects of these extreme events. It takes time, resources and finance to begin rebuilding after a tropical cyclone hits and many are ill-prepared for this recovery process. For years, many Fijian communities have been all too aware of and much too dependent on the disaster relief packages they receive post disaster occurrence from the Fijian government, FRCS, NGOs and even international aids. However, it should be made known that there are alternative forms of assistance available for individuals, businesses etc. in regards to disaster relief/rehabilitation packages. The aim of this legacy project was to map and update points of interests entailing locations and relevant information relating to financial institutions/bodies that offer or have in the past offered disaster recovery/relief packages to members of Fijian communities within the Northern and Central divisions.

Area of study

Palestra no Latinoware 2023

Tive grande satisfação em ministrar palestra sobre Geocodificação com OpenStreetMap no XX Congresso Latino-americano de Software Livre e Tecnologias Abertas - Latinoware, no dia 18 de outubro de 2023. O evento é promovido há 20 anos pela Itaipu Binacional e pelo Parque Tecnológico de Itaipu -PTI (Foz do Iguaçu, Paraná, Brasil).

Três estratégias para geocodificar com Nominatim/OSM

Na palestra, apresentei os aspectos relacionados à geocodificação com dados do OpenStreetMap e três estratégias que podem ser utilizadas para esse fim:

1. Script Python com biblioteca Geopandas + Nominatim
2. PostgreSQL (com PostGIS), pgAdmin4 + Nominatim
3. QGIS e Plugin MMQGIS

地理實察-1

I made it an obligation to participate in this years edition of the SOTM Nigeria. I must say, it was worth it; because the various topics presented during this year’s conference opened up my mind to new possibilities in the world of GIS. I am also immensely grateful to the sponsors of this event for affording me the opportunity to be awarded a travel grant. Thank you SOTM Nigeria, see you in Lagos in 2024!

Over the last few months, I’ve been filling out the houses and buildings in southwest London because I’m bored and have taken a strange fixation on improving the map in this way.

I have noted a few things over the last few months, particularly how the addresses to flats and rows of townhouses are managed. when marking out an area for a building of flats it only lets me put one address in, when flats typically have multiple addresses attached to the same physical building.

Not a major drawback at the moment but this is the main reason im not filling addresses in as there are typicaly more than one address attached to each building. Im not a coder here but this is my mild wednesday musing put on paper.
