mapping [France] Mapping missing streets

Background As a part of on-going work to improve the quality of OpenStreetMap Mapbox SDKs collect anonymous data and device location to continuously update data. Link to the OSM Wiki page. More information about telemetry is here.

We are now looking at mapping missing roads across of France the big cities. There may be more to come.

What we are going to map?

It will be different types of motorable roads (highway=* ) according to OSM Wiki. Mostly will map only geometry without names and ref (excluding cases where we prolonging existing road), and not going to map different types of restrictions only in cases where it's obvious and easy to confirm by ground truth sources.

How do we confirm it’s an actual street? Location data is used to identify possible new streets, hiking trails, and bike paths. We then confirm its existence with street level images (as Mapillary or Bing Streetside) and satellite imagery, and only then do we map the road.

What does telemetry data look like? More examples here

Example of using telemetry :

Example of mapping:

Here you can see a telemetry represented as bundle of ways (in blue color). Below screen OSM without a mapped road but we can clarify it with the satellite image and map it.

Contact person: We welcome feedback, suggestions, and insights from local mappers. If you have questions about this work, or a specific edit by our team, please reach out to Vlada at [email protected] or post a comment in a changeset.

A unique hashtag We will use the hashtag #mbx_missingstr_fr

Goal of the activity To improve map quality by adding roads.

Timeframe We are going to start in the first two weeks in June.

Any non-standard tools and data sources used, and their usage conditions We used some internal tools for processing driver’s feedback and collecting telemetry. And for OSM edits we use only OSM iD and ground truth sources (Bing, Esri, Maxar satellite imagery and street level sources such as Mapilary ).

Hi @vladaboitsik thanks for having sent the information on [OSM-talk-fr], normally the missing roads in France are known from Bano (comparing French land registry Cadastre to OSM data: https://bano.openstreetmap.fr/fantoir/index.html#insee=ref:INSEE&tab=0 indicates the missing highways with numbered houses and https://bano.openstreetmap.fr/fantoir/index.html#insee=ref:INSEE&tab=0 - Libellé BAN is the probable correct spelling of the street. ref:INSEE is the French ID of the commune. https://bano.openstreetmap.fr/fantoir/index.html#insee=ref:INSEE&tab=2 is the same for ways without numbered houses.

Another source for missing streets (and a way to get names but here the way types and possibly names are shortened).
