Suite à l’import des batiments et adresses en Belgique, j’avais comparé, dans un article précédent, le nombre d’adresses par communes entre OSM et la source de référence en Wallonie, le PICC, en septembre 2022.

Quelques mois plus tard, une mise à jour des principales figures.

En Wallonie, 1,097,519 adresses sont répertoriés dans OSM, contre 1,634,840 dans ICAR (67.1%). On était à 64.4 % en septembre 2022.

Voici une carte choroplète, montrant, pour chaque commune, le degré de complétion des adresses dans OSM par rapport à ICAR. Les limites de provinces sont soulignées par un trait plus gras.

According https://www.thedrive.com/the-war-zone/25728/chinas-new-york-city-sized-earthquake-warning-system-sounds-more-like-way-to-talk-to-subs there is a huge secret ELF-antenna in China called WEM. The exact location is so far unknown, but by the fact, that it looks like an overhead powerline which forms according https://www.newsweek.com/china-giant-antenna-navy-submarine-new-york-city-secret-location-1276332 a cross shape, so it will be able to be mapped by satellite pictures.

Last weekend, I had the opportunity to accompany a friend to an archaeological survey on Ballygawley Lough in Co. Sligo. He’s a metal detectorists who detects on archaeological sites - with a license. Metal detecting is highly restricted in Ireland. There were three divers - one of them had worked on Banshees of Inisheer and Vikings! (At least two of them do diving for movies regularly.) One of the divers doubled as metal detectorist as well, but he also had a sonar device on his canoe. When I had a peak at the screen, I discovered that it was using OpenStreetMap! With attribution! It’s the Lowrance Elite ti2, if anyone is interested. I can’t find any mention of OSM on their website.

There are two crannógs on the lake which was part of why I went with them. I had never seen one in real life, mapped a lot and discovered a few, but never actually seen one. I was offered the spare canoe, but I chickened out when it came to actually paddling over there.

Der Ablauf ist sehr ähnlich geblieben, ich schildere aber nochmal alles, den vorherigen Eintrag muss man also nicht gelesen haben.

Interessante Layer
Straßenbäume, Anlagenbäume

Sind zwei separate Datensätze, sind aber identisch aufgebaut. Leider fehlen teils Bäume, teils an der falschen Stelle, teils um eine Nummer versetzt, oder kombinierte Fehler. Teils fehlen neue Pflanzungen, oder gefällte sind noch zu sehen. Leider haben die neuen kleinen Bäumchen scheinbar nie eine Nummer, das dauert wohl einfach immer.

Straßenbefahrung 2014

Ich habe mich auf die Bäume und anderes Straßenmobiliar konzentriert. Es gibt im “Straßenbefahrung 2014” Layer mehrere interessante WMF, aus denen ich Daten ziehen kann, um diese vor Ort zu prüfen.

I’ve been invited to go to Jordan to consult on a new OSM project involving Jordan’s Royal Scientific Society, the local Youthmappers chapter in Amman, and the Princess Sumaya University, coordinated/commissioned by the UNESCO research chair, Science Communicator Iain Stewart.

The location is Asraq (think Lawrence of Arabia, and ancient Petra; the area sometimes called the ‘Cradle of Civilisation’. Over the centuries, the area has been settled and travelled by many people - from silk-road traders to Moses’s biblical journey, incoming 11th century Druze, to modern syrian refugees.

The wetlands have different cultural significance and inspire/necessitate different cultural practices for many ethnicities, and the now desert has gone through climatic and human-influenced changes which exemplify one of Jordan - and the planet’s - biggest challenges: water supply.

As with so many Disaster Risk environemnts, the problem is compound in nature: climate change has turned once fertile wetlands into desert, whilst Jordan’s excellent record of refugee hosting has meant massive population growth. Result: decreased supply and increased demand for water supply.

I’m looking forward to working with diverse local voices to understand how OpenStreetMap might present some solutions, and am expecting a fascinating mix attitude, behaviour and shared-interest around Water Resource mapping and with Community Asset mapping.

Sharing from my post on https://blog.georeactor.com

Belgium’s Baarle-Hertog and the Dutch Baarle-Nassau overlap in one town riddled with border crossings and enclaves. Let’s take a look at OpenStreetMap:

Map of Baarle-Hertog/Nassau full of border lines
Wow, it looks complicated!

Legend depicts Baarle as a Kafkaesque theme park where buildings swap countries and laws are fluid. Sample anecdote:

There was a time when according to Dutch laws restaurants had to close earlier. For some restaurants on the border it meant that the clients simply had to change their tables to the Belgian side.

I likely learned about this town from the Google Sightseeing Blog a long time ago. As a maps nerd, I knew that I had to see it for myself one day.

Getting there

In April 2023, I took a train from Brussels to Antwerp, checked out the award-winning Port Authority Building, then another train onward to Turnhout, then a bus to Baarle-Hertog.

L’antico toponimo chiamato: “Sa Pedra de Vanda”nelle vicinanze di Arcu Procili de Monte Melas, nei pressi delle localita’ “Sa Scandula” “Baccu Eranu” “Baccu Eraneddu” “Monti Arbu” “Pedra Bianca” Baccu S’Acua Callenti” ecc. ecc. NB il suo vero nome è: “Sa Pedra de Vanda”. Attualmente viene conosciuta con il nome ( La Sfinge - La Mitra - o Su Cappeddu de su Papa o de Monzegniori). Ma tra noi che conosciamo questi luoghi da piu’ 60 anni continuiamo a chiamarla con l’antico toponimo “ SA PEDRA DE VANDA”. C’è da dire che anche noi ogni tanto usiamo questi toponimi per evitare di fare sbagliare l’itinerario alle nuove generazioni, e visitatori che frequentano questi luoghi. Dimostrazione pratica come la toponomastica è in continua evoluzione.

amenity=hitching_post
Short and easy, 214 uses.

tourism=trail_riding_rest
Well, it may contain one or more hitching posts. 1 use. That’ll be the person who wrote it up for the wiki and linked it about for good visibility. Ooh, and it’s rendered on the trail riding map. Perhaps it was made because other resting places are possible, so this becomes a unifying tag to look for if you are looking for a place to rest your horse? Much like a tourism=trail_riding_station seems to be a unifying tag to put on all the different things you can overnight your horse in? (1339 uses for that one, it’s doing a better job. Oh, except that I looked at how it was actually being used and some of it was for staging locations where overnighting would be illegal. So not all correct uses. And I can definitely see where the confusion comes from.) Although if these things are meant to be a unifying device, used in addition to the more specific tags, it probably ought to say that on the wiki page. Is that even how tags are meant to be used? I certainly see the utility.

amenity=animal_hitch
animal_hitch=ring/rail/post
horse=yes
er…
mule=yes
donkey=yes
llama=yes
Perhaps you should just be assuming your zebra/donkey cross or whatever other exotic bit of stock you’ve got =yes? Except if you’re in big horn sheep country, it very well might be that goat=no.
104 uses for all animals, but it isn’t popular enough to get combination details. For the type tag, there are 83 rings and 7 rails, but no posts at all. Nope, the people don’t want it for hitching posts. Well, except for the sorts who get particular about the post being horizontal between two other posts, AKA a rail. Or particular about there being a ring on the post, but the example dog_hitch (not kidding) is also a ring.
Oh, there’s also 2 uses of amenity=horse_hitch.

OSM 위키문서에서 ‘길’ 갈래 가운데 주요길 갈래에는 motorway, trunk, primary, secondary, tertiary, unclassified, residential 같은 여러 값이 있습니다.(unclassified는 한국에는 해당하지 않음)
이 가운데 ‘motorway’는 ‘고속도로’, ‘trunk’는 ‘고속화도로’로 또렷하게 갈래지을 수 있겠습니다.(‘고속화도로’는 주요도로 가운데 계층적 성격에서는 살짤 벗어나기는 하지만 그 특성이 또렷하고 독립적이기에 계층적 갈래에 넣어도 문제가 없다고 봅니다.)
나머지는 우리나라 실정에서 갈래짓는 기준에 따라 조금씩 다르게 볼 수 있어 꼭맞게 떨어지도록 갈래짓기는 쉽지 않은 것 같습니다.
그럼에도 한국의 실정에만 맞게 새로 키 값을 만들기도 그렇고, 이왕이면 있는 공통 키 값에 가장 비슷하게 맞물리게 하고자, 여러 길의 속성들을 살펴 볼까 합니다.

먼저, 우리나라 길[도로] 체계부터 알아야 할텐데, ‘관리 주체에 따라’, ‘기능에 따라’ 혹은 ‘사용형태나 규모에 따라, 여러가지로 나눌 수가 있습니다.
“도로법”에 따르면 관리 주체에 따르면, 일부를 제외한 대부분의 노선은 공기업 한국도로공사가 국토교통부로부터 위탁받아 건설, 유지 및 관리를 하고 있는 ‘고속국도’(고속도로), 각 지방자치단체에 있는 지방국토관리청에서 관리하는 ‘일반 국도’, 특별시장·광역시장이 관리하는 ‘특별시도·광역시도’, 그 밖에 시장·도지사가 관리하는 ‘지방도’, 시장·군수·구청장이 관리하는 기타 군,시도 그리고 역시 시장·도지사가 관리하는 국가지원지방도(국지도)가 있습니다.
그렇다면 크게는 ‘고속국도’, ‘일반 국도‘그리고 광역 지자체장이 관리하는 ‘특별시도·광역시도’와 ‘지방도’를 묶어서 ‘지방도’, 시장·군수·구청장이 관리하는 ‘시도·군도·구도’ 정도로 뭉뚱그려 나눌 수 있지 않을까 싶습니다.
그 밖에도 차선 수나 넓이에 따라 나누기도 하고, 기능에 따라 ‘주도로’, ‘간선도로’, ‘집산도로’, 규모에 따라 ‘광로’, ‘대로’, ‘중로’, ‘소로’처럼 나누기도 하나 그 나눔이 그리 또렷하지는 않은 것 같습니다.

OSM의 계층적 분류에 따라 ‘고속국도’(고속도로)는 ‘highway=motorway’로, ‘일반 국도’는 ‘highway=primary’, ‘지방도’는 ‘highway=secondary’, 그 밖의 ‘시도·군도·구도’는 ‘highway=tertiary’로 나눌 수도 있을 것 같은데, 개념 상으로는 구분이 뚜렷하고 별 문제가 없으나, 일반 사람은 쉽게 알기 어려운 정보가 들어 있어, 이와 함께 좀더 알기 쉬운 기준과 함께 정리를 해 볼까 합니다.

먼저, 여러 분류 기준 가운데 가장 확실하고 ‘그나마’ 또렷한 기준은 ‘관리 주체’를 기준으로 한 분류겠으나 판단하기가 까다롭거나 어렵기 때문에, 국토지리정보원에서 제작한 지도를 기본으로 하고 있는 국토부 ‘브이월드‘나 상업지도 가운데 일부는 색깔로서 비교적 또렷하게 구분을 해 주고 있어 참고를 하기가 좋습니다.
