Talk presented at the 2016 State of the Map conference in Brussels, given by Antoine Riche (Carto'Cité) and Adrien Pavie (developer of OpenLevelUp and iD-indoor). Through this talk we highlight usages where indoor mapping is useful. We then describe the techniques used to produce OpenStreetMap data for the interior of Paris railway stations, on behalf of SNCF Transilien. Finally we share what we see coming next regarding this new dimension for OpenStreetMap data.

TOOLS

11. 11Usages Tools Prospects
Phase 1 : architect plans
Steps :
●
Convert DWG &
PDF to images
●
Georeference
with QGIS
●
Produce tiles with
GDAL
(up to zoom 23)

12. 12Usages Tools Prospects
Mapping from architect plans
Precise mapping
(~ 10 cm accuracy)
Not so easy :
●
which way up ?
●
what levels ?

CONCLUSION

29. Looking around
Converge with
other projects :
● share practices
● share tools
● share new tags
● share icons

30. Going forward…
● Topology : share nodes across levels ?
● Routing : help engines with linear footways ?
● Geocoding : get to level and room ?
● QA tools : need specific rules ?

31. Thank you for
your attention !
