German version

Initial Situation

In the forum, a user reports that a road on Crete is not being displayed completely. It quickly becomes clear that the German style is being used for rendering.

Openstreetmap.de operates two tile servers. On both of them, the tiles are faulty. It would be quite a coincidence if this were a hardware issue or a specific data import problem. Therefore, it is very likely that the cause lies within the German style itself.

The only difference between the two road segments is that the visible part contains one additional tag, namely maxspeed:

First Attempt

In the first attempt, I added a tag, namely the surface surface, to the missing segment and forced the German server to re-render the tiles. As a result, the previously missing part of the road appeared. This brought me one step closer, but it is not a solution yet.

Second Attempt

The German style is based on the standard openstreetmap-carto style, which is used on openstreetmap.org for OpenStreetMap maps. It adopts the basic rendering but selectively modifies certain elements to make them more readable for Germans.

I was curious whether the missing road segments were also absent in the original style. Therefore, I rendered them using that style. For this, I used render_single_tile.py and retrieved the necessary information by right-clicking on the corresponding tile at https://tile.openstreetmap.de.

First, I rendered with the German style, where – as expected – the road section was missing:

render_single_tile.py --zxy 17 74577 51762 --stylefile openstreetmap-carto-de/osm-de.xml --outputfile site/rendersinglefile/1.png

Then with the original style, where the rendered tile was also incomplete:

render_single_tile.py --zxy 17 74577 51762 --stylefile openstreetmap-carto/mapnik.xml --outputfile site/rendersinglefile/3.png

From my understanding, this made it clear that the error already occurs when importing the OSM data into the database.

Sziasztok!

Az élet sodor, gyakran mint egy hurrikán. Ugyan kevés olyan időm akad, amikor OSM-el tudok picit foglalkozni, gyakran fut át a fejemen, hogy ezt-azt megnézek a térképen a környezetemből és majd javítom, szerkesztem, ha eltér. Nyilván ettől sokkal kevesebbszer érek oda, de azért párszor már összejött.

Továbbra is érdekel és fogok is szerkeszteni.

Néha még a JOSM-ot is frissítgetem az aktuális verzióra, akkor is, ha közben mégis az ID-n egyszerűbb és gyorsabb valamit igazgatni. A kis dolgoknál ez így is marad, de ha nagyobb varázslat szükséges, a JOSM is jó, látom, ha nem is sűrűn, de még mostanában is frissítették.

Az OSM továbbra is kedvenc koncepció a szememben és örülök, hogy jó ideje stabil és fejlődik.

Üdv, V.

It was another beautiful, sunny day in Orange. I’m toying with the idea of conjuring up some sort of regular Saturday mapping activity, solely so I can use the word “Mapurday”, even though I’ve mapped at least one thing every day for the last five days. I’m sure that will slow down a bit once I re-balance the other parts of my life (although I did add a bench in Riverside last night while waiting for a friend to arrive; it doesn’t take much to contribute!). I’m not sure if it will be just for myself, or I want to try to get other local mappers involved.

It was a productive day! My goal was to add more fire hydrants along Palmyra, and to catch one I had somehow missed along Almond. I can’t say it’s representative, but so far, the manufacturers have all been one of:

  • Rich Valve Co. (or Rich Manufacturing Company; I’ve seen both and other variations in newspaper clippings)
  • M. Greenberg’s Sons
  • Long Beach Iron Works
  • Clow (Valve Company)

There’s also one Van Deventer, which firehydrants.org says could be a company, but it could also just be a fire hydrant produced under license. I plan to do a little newspaper digging to see if I can learn more.

Orange Street Barbershop

I added the Orange Street Barbershop to the map. I’ve been correcting several missing or otherwise out-of-date business POIs in addition to my quixotic hydrant mapping quest. The previous salon for 120 S Orange St was long since closed, so I updated it for the new business. I also noticed that the entire building was marked as the salon (now barbershop). I switched this to an individual node because the Orange Street Barbershop is technically suite B; there’s a suite A with doors set a bit back into a covered part of the building, but they don’t seem to be for anything useful.

根据wiki的中文词条解释。在补充村庄名字时,请不要在居民区要素上(landuse=residential)直接写名字(name),而是另外加一个place=village(行政村或较大村落)/place=hamlet(自然村)的标签后,在该标签上再加村庄名称。住宅小区则可以直接在居民区要素上加上该小区的名字。 另外,为了规范与整洁,请在补充行政村名字时加上村字。比如王各庄村、杨官寨村,而不要标注成王各庄、杨官寨。感谢。

Quand on essaie de regarder Panoramax en dehors des agglomérations et des routes, dans la plupart des régions c’est le grand désert.

Pourtant, pour les randonneurs par exemple, ce serait bien de pouvoir utiliser Panoramax comme le StreetView des sentiers. Quand on veut planifier une sortie dans un endroit qu’on ne connait pas, on aimerait bien avoir un aperçu de quelques chemins pour voir ce qui parait intéressant, ce qui semble facile ou difficile… Malheureusement, à part un petit nombre de passionnés, peu de contributeurs se baladent, à pied ou à vélo avec une caméra 360° en prenant une vue tous les quelques mètres. La couverture des chemins dans une région donnée avance donc très lentement, ou la plupart du temps pas du tout.

Pour remédier à cela, l’application Baba offre une solution parallèle pour accélérer les choses. Lors d’une sortie ordinaire, pas forcément dédiée, on peut caractériser les sentiers en cours de route avec quelque dizaines de photos et envoyer les résultats sur Panoramax soit au fur et à mesure, soit le soir en rentrant.

Bien sûr, cette méthode “artisanale” n’est pas parfaite, un utilisateur aura toujours envie de savoir ce qui se passe entre deux points de prise de vue ou sur le côté comme avec une vue 360° mais ça a le mérite d’exister et de pouvoir être pratiqué par un plus grand nombre de contributeurs. Cela n’empêche pas d’autres contributeurs de repasser un jour derrière avec une technique plus complète.

J’ai commencé à mettre en pratique cette idée dans ma région.
Voir par exemple ce sentier comme point d’entrée, puis explorer la carte pour voir ce qu’il y a autour.

Quelques idées de base

Au fur et à mesure des aller-retours entre les prises de vue et les résultats sur les visionneuses, j’ai essayé de dégager quelques trucs utiles pour améliorer les résultats.

Když přemýšlím o mapách budoucnosti, nevidím jen další technické vylepšení zobrazování terénu. Vidím především změnu v tom, jak si společnost uvědomuje prostor a jak skrze něj řídí svůj život. Mapy postupně přestanou být pouhým popisem povrchu. Stanou se další nervovou soustavou civilizace.

Dnes máme mnoho typů map, které pokrývají téměř vše co nás napadne. Infrastruktura, příroda, vlastnické vztahy, doprava, služby, počasí. Přesto stále cítím, že jsme na začátku. Reálný svět je dynamický a v pohybu. Mapy se této dynamice teprve učí stačit. Čím více bude naše civilizace žít v komplexitě a proměnlivosti, tím více budeme potřebovat mapy, které tuto živost zachytí.

Představuji si mapy s mnoha vrstvami, které proudí v reálném čase. Data o energiích v budovách. Signály o nasycení veřejného prostoru životem. Místa kde se rodí napětí i místa kde vzniká spolupráce. A také vrstvy, které nebudou mít pevnou interpretaci. Emoce, nálady, očekávání. Nějaké ostrůvky pocitových map už tu máme. Budou mapy, které připustí nejasnost jako přiznanou informaci. Mapa už nebude jen obrazem toho co je. Bude také předpovědí toho, co při dobré definici podmínek může být.

To vyžaduje mnohem víc, než nové technologie. Vyžaduje kulturu důvěry. Transparentnost původu dat. Pravdivou informaci o tom, kdo o mapovaném prostoru rozhoduje a proč. Když se mapa stane podkladem pro rozhodování, musí být otevřená kontrole. Musí být srozumitelná těm, kteří ji potřebují číst. Musí ctít práva tvůrců i práva lidí, kteří jsou v ní zaneseni svými domovy nebo svými pohyby.

About a week ago, vandals began defacing the map in South Korea. Over the course of that week, I rolled back hundreds of changes, and with the help of the site’s moderators, I banned over 50 malicious accounts.

In fact, the problem arose not even a week ago, but about a month ago. Back then, South Korean media reported that one account had allegedly leaked the locations of all the country’s military bases to the public on Openstreetmap. (link)

Even then, this false media claim struck me as disgusting, but it didn’t cause any major problems. Almost simultaneously, another Korean media report about Openstreetmap appeared: allegedly, an error in the domestic mapping services NaverMap and KakaoMap displaying a river in North Korea was linked to Openstreetmap’s activities: (link)

A cidade de Uberlândia Minas Gerais cresceu muito ultimamente em relação à 11 anos atrás.

Nesses meses estou atualizando o mapa da cidade com novos condomínios, estradas, e etc.

Utilizei dados do mapa da prefeitura para atualizar nomes oficiais de ruas, avenidas, bairros e chácaras. O centro da cidade foi atualizado e corrigido principalmente nos bairros Fundinho, Centro e Nossa Senhora Aparecida. Córregos e o Rio Uberabinha estão corrigidos, os Setores da cidade foram corrigidos e nas próximas atualizações será mais corrigido e o mais detalhado possível!

Att, ricaestevao

Sometimes some maps are more satisfying than others. What I did on “Cho-do” (“초도”) — Cho island — is definitely one of them!

Cho-do in North Korea is one of the largest islands in the country, and today we can proudly say that it is fully mapped on OpenStreetMap!

In this diary, I explain the small steps I had to take to achieve what I consider to be — among the various places I have mapped — the most complete area !

See it directly on OpenStreetMap!

IMG 1 - CHODO ISLAND MAP NORTH KOREA

Why an island?

I have been able to map various locations in North Korea (and a few other places), but there are few areas that are as well-defined as islands — which are not too large either — to map completely.

The idea of doing an island came to me from a contributor, @Lyokoï, who plans to map at least one island in every country/territory in the world. I love the idea, but if I were to take on this kind of project, it would be to map all the islands of North Korea 🤭!
