Introduzione

In questi ultimi anni e in concomitanza dell’anno degli Etruschi si è riscoperta questa strada etrusco-romana: lungo il suo ipotetico percorso da Ponte Milvio (Roma) a Roselle (Grosseto) si è assistito al fiorire di numerose iniziative, ad es. sono nati gruppi e associazioni (molti presenti sul www) e proposti progetti per la sua valorizzazione storico-turistico-ambientale; nonostante ciò di fatto ancora manca sul terreno un tracciato escursionistico che colleghi i siti archeologici certi della Via Clodia.

Molte iniziative hanno indicato percorsi che dal punto di vista storico ed archeologico non hanno alcuna attendibilità: spesso si è confuso uno o più diverticoli romani con la Clodia, oppure, è bastata la presenza di resti etrusco-romani per affermare che “qui passava la Clodia”; tra i casi più manifesti vi è quello del percorso 105 segnato dal CAI Viterbo “Via Clodia”¹.

Il tracciato da me proposto su OSM, Relazione Antica Via Clodia (7990604)², è un iniziale e fattivo contributo frutto di conoscenze personali, per il tratto Roma-Tuscania, e dello studio di numerose fonti quali le relazioni e gli studi archeologici.

Recently there have been well-reasoned calls to give users blunt feedback when they have strayed. It came to my attention that the wiki has no built-in feature for this social interaction, only the reverse. I have implemented a user script that allows you to chide another user for an edit. For example, I stridently disapprove of this edit from a year ago:

The OSM Help Desk of the Open Mapping Hub Asia-Pacific is slowly and steadily continuing while we discuss different matters with different people every week, both online and offline, when scheduling and connectivity doesn’t allow us to meet online. And I am also personally enjoying these discussions since I am too, refreshing or expanding my knowledge on some topics along the way. So please keep the appointments coming via this online form.

Discussion Topics:

• ”I am part of an organization and we want to be advanced OSM contributors.”

There are lots of entry points to get to know about Openstreetmap: Wiki being the main one and LearnOSM another very good resource for this purpose.

But if you’re also aiming to gain expertise and become trainers in your community, or planning high-impact mapping projects and activities and want to build capacity on those, please let HOTOSM or the Open Mapping Hubs in Asia-Pacific, Eastern and Southern Africa, Northern and Western Africa or Latin America to learn how they could help you achieve these goals.

• ”I would like to learn how to map properly. Especially on Tasking Manager.”

Again, the Tasking Manager section of LearnOSM is going to provide almost everything you need to know on how to properly contribute to OSM using Tasking Manager.

Additionally, please feel free to use and distribute this little cheat-sheet we’ve recently put together at the Hub. Squeezed in and packed up knowledge for you, bragging rights for us :)

Heute festgestellt, dass ich schon seit über 10 Jahren in OSM aktiv bin. Und es macht noch immer Spaß und gibt immer noch viel zu tun. Aktuell laufen Ergänzungen, Komplettierung und Aktualisierung der Bestandsdaten mit StreetComplete am Handy.

Die Bedienung ist kinderleicht - kann ich empfehlen.

  Hello Mappers
                   I caused a few routing errors when I first started mapping because I didn't check that the final node of a path I had mapped was connected to another path, track or road. I didn't know about routing then. Seeing an image of a dotted path at a road looked to be an obvious connection. But when using a routing engine routing would fail.
     Since I started to use routing engines more. I have discovered more faults. They are often caused by tagging omissions.  Unless a way allows the mode of transport that you have selected the routing engines will not use that  way ( path track or road).   Some mappers in England know that a Bridleway is a legal right of way for foot, cycles and horses and  they assume routers will use these ways, But they don't.  For any rights of way we need to add foot=yes for footpaths.  Bridleways  need all three tags,  foot =yes, cycle=yes, and horse=yes, to get routing engines to work as expected.   Potlatch and iD editors have these  tags built-in but you will have to select  each one of them.   When we edit the map the database is changed instantly,  the drawn map will maybe need a refresh to renew the display however. (ctrl  F5  on my Win PC)   We would hope we could quickly test the routing after our mapping or correction, but we cannot. OSRM and GraphHopper only update their copy of the map data every few days.  For this reason we will have to check a few days later.  see this please https://help.openstreetmap.org/questions/83945/foot-routing-failing-bridleway-alone-doesnt-let-it-work-it-needs-footyes
                                                                                                                                              Happy Mapping and Routing
                                             Andy                                                                                                                                            

Introduction

Lorsque l’on arpente le terrain, il n’est pas rare de devoir justifier sa présence un peu trop scrutatrice. C’est l’occasion d’expliquer et de faire connaître le projet.

L’association OpenStreetMap France avait élaboré un dépliant de communication très clair et joliment présenté (voir ici) mais qui a l’inconvénient de prendre beaucoup de place pour que l’on se promène toujours avec.

La carte de visite a un format idéal pour rester dans le portefeuille en attendant qu’elle soit utile. J’en ai trouvé plusieurs versions sur le wiki :

Hello Mappers I do a lot of walking in the English countryside. Sometimes I plan routes and find these two “engines” very useful.  GraphHopper https://www.graphhopper.com/    and OSRM https://openrouteservice.org/  These two routing engines are on the main map page and use openstreetmap data. Try them out, click on the bent arrow and select a couple of points, select mode of travel. for example  osm.org/directions?engine=graphhopper_foot&route=52.3099%2C-0.3175%3B52.2873%2C-0.3173 move the point a little and you have osm.org/directions?engine=graphhopper_foot&route=52.3100%2C-0.3158%3B52.2873%2C-0.3173 You now have a route, a distance and elevation trace of almost the whole circuit  of Grafham Water Reservoir.    Sometimes two points will generate an odd route. My next diary entry will cover some of the problems and how to fix them.                                Happy Mapping and Route Planning Andy

Quand j’ai commencé à cartographier sur Openstreetmap, je me souviens avoir été confronté à pas mal de questions : que ce soit sur la prise en main de l’éditeur en ligne (iD), sur les codes et bonnes pratiques à respecter, sans oublier le cadre légal des sources de données utilisables.

Avant de me lancer, je m’étais assez bien documenté. En fait, je me suis d’abord intéressé au projet : sa philosophie, son fonctionnement et sa communauté, c’est ce qui m’a motivé à participer. Ensuite, afin de respecter au mieux le travail déjà accompli et d’apporter des modifications correctes,  j’ai appris pas mal de choses. Je suis passé par plusieurs sources : le guide du débutant, LearnOsm, des vidéos, le forum etc.

Malgré cette approche, on se rend vite compte que si on veut contribuer du mieux possible, plus on avance, plus on se pose de questions.

En monitorant l’activité de nouveaux venus ou de lycéens de SNT, je me suis rendu compte que, de manière générale, ce sont toujours les mêmes erreurs qui reviennent. À partir de là, l’idée d’établir des règles d’or m’est venue. Pour donner un côté un peu décalé, j’ai imaginé reprendre les 10 commandements à la sauce OSM.

Cependant, si c’est rigolo entre contributeurs avertis, ce n’est pas forcément parlant pour des novices. Il fallait un support plus pédagogique et agréable à découvrir qui puissent servir à la fois à des contributeurs isolés comme à un groupe lors d’une cartopartie par exemple.

I’ve fixed some of the limitations of my note viewer that were discussed at the end of this diary post.

1. Now you can use this tool as a more general interface to /api/0.6/notes/search OSM API requests. Providing a username is no longer required, and it’s possible to do comment text searches and limit the results to date ranges.
2. Search queries are encoded in URLs. That opens some additional possibilities.
3. Earlier you could accidentally load too much data that would slow down your browser too much. There weren’t an obvious way out of this situation because the tool always tried to restore the results of the last request. Now it shouldn’t be a problem - just open the page without the query in the URL (without everything after #). Or press the (x) button on the top.
4. You can open several different requests in different windows at the same time. There’s still one problem left: opening the same request in different windows is not guaranteed to work.
5. Since queries are stored in URLs you can share links to them. Also you can generate links without typing stuff into the search form. For example, you can use OSM Smart Menu browser plugin to switch to user’s notes as shown by this tool from any webpage that the plugin associates with the user. You need to add this URL template in OSM Smart Menu settings: https://antonkhorev.github.io/osm-note-viewer/#mode=search&display_name={osm_user_name}

The OSM community in Ireland is engaged in another multi-year mapping project, to map all the buildings in Ireland.

By March 2022, there were over 2,000,000 buildings. Which caused someone to ask “What was the 2,000,000th building?”. So who added #2,000,000? 🥁 drumroll…

The 2,000,000th Building was added by Boggedy on 1st March 2022, and is in An Bhealtaine Íochtarach, Gort a’ Choirce, Co. Dhún na nGall! Technical OSM details: It’s way 1,036,394,489, added in changeset 117,996,721.

Here’s other milestones:

Installation

If you want to calculate this data yourself:

• Download the latest full OSM history file from Geofabrik for Ireland (ireland-and-northern-ireland-internal.osh.pbf currently 381 MB).
• Create a local PostgreSQL database.
• Install the latest version of osm-tag-csv-history (technically ≥ v0.5).
• Download the code from Github amandasaurus/osm-two-million-buildings-in-ireland
• Run ./calculate.sh. results.csv has the output.

Seguramente sea diminutivo de “escada”, escalera. En la parte superior hay una serie de escalones en la piedra granítica, o bien levemente trabajados y desgastados por el uso, tras aprovechar la propia estructura natural de las piedras.

A Escadiña es un sendero estrecho con dos ramales unidos: puedes subir desde la Poza da Lama o desde el fondo del camino de A Pena do Campo. Ambos empatan en el punto central y suben hasta una zona del barrio de A Torre, con buenas vistas de la contorna y varios hórreos (canastros, les decimos) en diferentes estados de conservación.

In the U.S. mapper community, we often joke about how tagging dictates by out-of-staters or people from overseas amount to saying, “Fix your state!” We’re such contrarians over here, probably because we live in such a messy place. In fact, my home state of Ohio exists primarily to give mapmakers heartburn and keep data consumers up at night, especially when it comes to boundaries. At least in this state, making assumptions about boundaries is almost as bad as making assumptions about names.

Administrative boundaries in an ideal world

OSM represents administrative areas as boundary relations that geographically encompass other boundary relations with higher admin_level=* values. In the early days before boundary relations became well-established, some mappers used to represent boundaries as multipolygon relations. The inner and outer relation roles stem from this usage. Data consumers often use similar code and tools to process both boundaries and multipolygons because so many well-known boundaries follow all the same topological rules.

The illustration that accompanies the wiki documentation for the admin_level=* key suggests a simple hierarchy of administrative areas, in which a larger area completely contains a smaller area and so on:
