The document discusses a pilot project by DB AG and Akaparis GmbH to map railway stations indoor spaces using OpenStreetMap (OSM). The goals are to improve navigation for customers and utilize digital mapping. Phase A maps 4 stations in Germany to prove the concept. It develops an OSM data model and extensions for railway features. A web client visualizes the indoor maps. Phase B will focus on mapping elevators across stations to gain more experience. The results show OSM can effectively map multi-level indoor spaces like stairwells and stations. The organizers invite others to join and help expand coverage to more stations.

3. 1.1. Introduction
Deutsche Bahn Infrastructure

4. 1.2. Introduction
DB mindbox Berlin: Innovating Railway Infrastructure
 New Open Data portal,
http://data.deutschebahn.com/, Start in
November 2015
 Upcoming API for the operating status of
elevators as a 1st approach
 Friday, December 11th + 12th at Berlin-
Jannowitzbrücke
 Register for free at:
https://www.mindboxberlin.com/index.php/3rdhackathon.html

5. 2. Motivation, Goals and Challenges
 Questions:
– How can we improve navigation through stations for our customers
(e.g. handicapped people, elder people, young families etc.)?
– How can digitalization help us to achieve this goal?
 Goals
– Better information stream between operator and customer within railway stations, e.g. change of
platform or wagon order.
 Challenges:
– Lots of DB Data, but in different context and not combinable (e.g. CAD, Images, Inspire)
– Several DB Maps, but not usable for purpose (e.g. zoom level)
– Lots of Data in OSM with strength on outdoor objects and / or no standard for objects in indoor areas
an design relations (e.g. Lift, stairways etc.)
– 5.600 train stations with a lot of change inside !!!
– Semi-public space, therefore suitable for OSM
– Interfaces and legal questions
 Motivation for cooperation with Akaparis and presentation today:
– Proof of Concept: can OSM help to solve the problem (e.g. map a station indoor and show levels an
information in a specific context

6. 3. Phase A:
OSM Pilot to run a prove of concept

7. 3.1. State-of-the-art:
OSM and Railway stations
Railway stations are mapped
already with existing tags
Similar to general buildings,
indoor is missing
Railway station specific features
are not introduced yet, e.g.
platform sections
with four railway stations, Berlin
Ostbahnhof, Berlin Südkreuz,
Dresden Hbf and Berlin
Jannowitzbrücke

8. 3.2. ORSM Data Model
 OSM Indoor Modeling concepts and extensions
– Based on Simple Indoor Tagging,
http://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging
– stairwells and parts refined and extended
– doors refined and extended
 Railway Station extensions
– Service Points, Service Centers, Lounge, platform sections
 Take (OSM tool) visualization into account
 Documentation
– http://www.openrailwaystationmap.org/0.1.1/datamodel/OpenRailwayStatio
nMapTags.docx
 Composition of existing and extended features into a practical set to ease
the usage
– JOSM Preset
– Download http://www.openrailwaystationmap.org/0.1.1/datamodel/ORSM-
Pilot-datamodel.xml
 Integration into OSM environment (wiki) as next step

9. 3.2.1 JOSM Preset ORSM

10. 3.2.2 Documentation
 Collection of description, definition and
pictures
 To be moved into OSM wiki

11. 3.2.3. Example Stairwell
Enhanced concept for Level connection, e.g. Stairs, Elevators
indoor=corridor
level=0
well=lightwell
level=0;1
stairwell=yes
level=0;1
public_transport=platform
railway=platform
level=1
highway=steps
width=2
level=0;0.5
highway=steps
width=2
level=0.5;1
highway=footway
highway=footway
level=0
highway=footway oder path
level=0
highway=steps
conveying=yes
width=2
level=0;1
Type:closedway
stairwell=flight_of_stairs
level=0.5;1
Type:closedway
stairwell=flight_of_stairs
level=0;1
Type:closedway
stairwell=flight_of_stairs
level=0;0.5

12. 3.3. Data Visualization with OSM
Leaflet concepts and MapCSS with special efforts for area styling
for stairs (which requires already data model definitions); working
style for JSOM (see below)
Current clients on single OSM file basis, future on overpassAPI basis
Indoor requirements:
Higher zoom levels are
required, current max
is about 19/20, zoom
level 21-23 will be
required
Currently DB Style,
later generic style

13. 3.4. Tools
Although some mobile OSM tools, like Vespucci or OSMTracker exist, missing
GPS turns to current paper based solutions, (fieldpapers.org is an option, but
would require higher zoom levels), Tango will help!?!?
Intention: Capturing with Laser Distance Measurement Device, e.g. Aldi and
Bosch, low cost, 40-80 EUR
Editing with JOSM and plugin “Measurement”

14. 3.5.1. Web Client and Service
• Leafletjs extension with additional e.g. osmtojosm libs
• Current: publication of pilot data
• new work stream on OSM worldwide data flow
• Icon Zoom Clustering

19. Next steps:
Phase B

20. 4. Phase B: Gain quantity experiences by a selected feature:
elevator
Lift as first good feature /
object to join the outside with
the inside OSM-world
2.200 Lifts
Published on open data portal
Enhancement for lift operating
status: missing georeferences
for about 900 lifts (due to
permanent change)
Cooperation with OSM
community an Open
knowledge foundation to
georeference them

22. 5. Conclusion
DB OSM Pilot proof of concept: successful
Strong visualization of levels with indoor and railway station specific
objects
–Stairwell with stairs, escalators and elevators of multiple levels
–Doors
Good solution for re-use in other buildings, e.g. hospitals
Cooperation with OSM Community to expand and to maintain is
necessary and welcomed
Work in progress – invitation to join up
Need to set up sub-community for Railway stations, e.g. other
countries?!
