Metro Mapping Proposal (and what's wrong with proposals) 6 months ago

Damn, I saw the voting only because of WeeklyOSM. I hope you won't abandon it because although was "rejected" by the wiki users, it's useful and used/usable by some applications. Thanks!

RFC: wikidata->osm lookup table about 1 year ago

The list could be generated from WMF side, I suggested it for example in

Surfacing Wikidata objects with coordinates to match them with OSM about 1 year ago

Here's the code if someone is interested to replicate in another country.

Surfacing Wikidata objects with coordinates to match them with OSM about 1 year ago

I use the Merge gadget (turned on from, remember to merge in the lowest number.

As for the merged items, they should disappear after the next wikidata dump release perhaps, we'll look into it and update the query.. now supports internationalization, geolocation in browser about 1 year ago

Thank you! I could try to propose the other changes from my fork (the version at as pull requests if needed. Mainly: accessibility data à la Wheelmap and payment options

100 € for multiple social accounts in OSM over 1 year ago

Would it be worth to use Bountysource?

State of the Map : Some BoF sessions over 1 year ago

Here are all the (top 200) trees in a radius of 300 km around Praha (Czech Republic)

SELECT ?item ?itemLabel ?location WHERE { ?item wdt:P31 wd:Q10884 . ?item wdt:P625 ?coords . wd:Q1085 wdt:P625 ?centerLoc . SERVICE wikibase:around { ?item wdt:P625 ?location . bd:serviceParam wikibase:center ?centerLoc . bd:serviceParam wikibase:radius "300" . bd:serviceParam wikibase:distance ?dist. } SERVICE wikibase:label { bd:serviceParam wikibase:language "en" } } LIMIT 200

Fast explaination: "wd:" is the prefix of an object (URI in Linked Data terminology) Qxxx is an object id Pxxx is a property id (proposed and defined through a process) Each value could be another object or a string ?variable is a variable (like $x in PHP) which could be used in the SELECT (acting as a column in the result table) or in the WHERE (the 'filters') WHERE is where you put the filters: the data model is made of triples (subject predicate object) and this is reflected in the query syntax. each filter is terminated by a dot and subject or object can be both variables.

To use wikidata query service you need a basic understanding of SQL (for how querying works), RDF (for the logic behind the system) and Wikidata to search for properties and objects...

We could see if there's enough interest to start some sort of discussion / user group :-)

New Telenav tool: Fix missing and wrong one-way streets over 2 years ago

Nice, I fixed some streets already!

Doing some highway/routing QA with Mapbox's Distance API over 2 years ago

I wrote a tool to bruteforce routes with OSRM (before distance matrix was implemented), but I didn't succeed in using it as a QA tool because of the amount of data required - for a country. Instead I did use it at regional scale to compute matrices between points.

Valhalla could be cool to try for this kind of tests

1.6 Gigapixel image - OSM Point of Interest density map of Europe over 3 years ago

Beautiful! Thanks for this visualization.

Does it render? almost 4 years ago

Yes, it originally did that with Mapnik vs Carto.. The code in itself it's extensible, it only needs a json with the handled tags.. (as I didn't find a way to automatically search tags easily in the sql queries, we could only consider Filter entries for example).

Does it render? almost 4 years ago

Thanks jongleur :-)

I added some phrases in the output which point to Wiki and TagInfo for the user to gather more info... Some tag wiki pages used to have a description of the result, didn't them?

I mapped 100 countries in 100 days about 4 years ago

@AndiG88 Dunno, it would be like to post on Twitter/Instagram a map? :)

@wille: thanks!

Creating a map with markers imported from OpenStreetMap over 4 years ago

Also Overpass Turbo can export to via a gist :-)

What is the OpenStreetMap convention? Do we tag addresses on buildings or on separate nodes? over 4 years ago

In Italy there are also two cities (Genoa and Florence) where there's distinction between addresses for buildings (black addresses) and for commercial activities (red addresses)!

I map on a node not to overcomplicate mapping... And I don't like the interpolation, but that's a personal taste :-)

OpenStreetMap and the Public Domain over 4 years ago

I think this could be solved by updating the contributor terms to provide exception to your "I want my data back!" section in case of government or ngo for example... In these "public service" cases perhaps less bureaucracy is better...

SASA bus stops import over 4 years ago

Potrebbe essere una attività per OSMit nel caso.. :)

Appena arrivato over 4 years ago

Ciao, gli autori di iD stanno lavorando con gli sviluppatori di Firefox per migliorare le prestazioni, le versioni in sviluppo dovrebbero progressivamente migliorare... :)

Benvenuto! Se hai bisogno non esitare a contattare altri mappatori.

North Korea is strange almost 5 years ago

@Paul: the map it's a wiki :3

@Popolon: awesome!

I wonder if on a micro-mapping level we shoud map each letter :D

North Korea is strange almost 5 years ago

Cool, thanks! I supposed was some sort of message from the Leader :-)
