MENTZ GmbH/Modellierungsvorschläge Indoor

The points below should provide support for indoor modeling in OpenStreetMap. The topics are presenting a collection of information, which was taken from OSM-Wiki. The aim is to reflect the guidelines for modeling real features. We are thankful for any annotations and comments: MENTZ Kontakt

Footways

This abstract describes all details, how pedestrians can reach public transport. For providing pedestrian routing in OSM, it is necessary that footways are connected from the street to the platform. Accessible (barrier-free) routing should be enabled by the consideration of adding elevators, ramps or escalators.

Horizontal pedestrian structures/ Footways

Footways

Footways inside buildings are tagged with highway=footway, level=* and indoor=yes. If they are illustrated in areas (halls, corridors), the tag indoor=corridor should be used.

Key	Value	Description	Example
highway	pedestrian	For pedestrian area
indoor	corridor	Indicating, that the area should present a corridor (or hall)
area	yes	bei Flächen obligatorisch
level	integer	Indicating, on which level the corridor is located
description	description	More detailed description for the corridor

Vertical pedestrian structures/ Steps, elevators & ramps

Vertical structures are divided in chamber-shaped elements (elevators) and in structures, where a predefined slope is given (steps, escalators, ramps). The sloping line is used in OSM for steps, escalators & ramps and shows the footway with the biggest slope.

Steps

Steps are tagged with highway=steps. If they are inside a staircase, the tag levelpart=step_platform + steps + indoor + area=yes should be applied.

Key	Value	Description	Modeling	Image
highway	steps
incline=*	up/down	Indicating, if steps are going up or down (in drawing direction)
	* %	Accurate allegation of the slope. A negative value means that the steps are going down (in drawing direction)
level	integer	Indicating, which levels or floors are connected by the steps. The ending points of the steps get level tags. If the steps are connecting level 1 and 2, then the ending points are tagged with level=1 on one hand and with level=2 on the other hand. The step border gets the tag of the lower ending point
indoor	yes/no	Indicating, if the steps are located inside a building

The minimum gap for modeling two steps next to each other is 2,00 meters between the two sloping lines.

Escalators

Escalators get the same tags as steps. Furthermore the tag conveying=* is added.

Key	Value	Description	Image
highway	steps	rowspan=9 |
conveying=*	forward	The escalator is carrying the pedestrian into the drawing direction
	backward	The escalator is carrying the pedestrian against the drawing direction
	reversible	The direction of the escalator is reversible
	yes	Generalization of the three other values. Can be applied if the direction is unknown
incline=*	up/down	Indicating, if the steps are going up or down (in drawing direction)
	* %	Accurate allegation of the slope. If the steps are going down (in drawing direction) a negative value will be applied
level	integer	Indicating, which levels or floors are connected by the steps. The ending points of the steps get level tags. If the steps are connecting level 1 and 2, then the ending points are tagged with level=1 on one the end and with level=2 on the other end. The step border gets the tag of the lower ending point
indoor	yes/no	Indicating, if the steps are located inside a building

The minimum gap for modeling two escalators next to each other is 2,00 meters between the two sloping lines. If escalators are next to steps, the sloping line minimum distance shouldn't be below 1,80 meters.

Elevators

An elevator consists of a point and a of basic area. The area gets a level-tag, which includes all floors, where elevator-chambers are existing (levels are separated by semicolon, e.g.: 0;1;2;3;4;...). To proceed a well working pedestrian routing, all elevator points should be connected with the footways on every floor where the elevator is moving.

Elevator areas

The elevator areas are containing the following characteristics:

Key	Value	Description	Image
building:part	elevator	Indicating, that an elevator is part of a building construction
area	yes	This tag is needed to identify areas
level	integer	Floor of the elevator area
indoor	yes/no	Indicating, if the elevator is located inside a building.

Elevator points

The elevator points are containing the following characteristics:

Key	Value	Description	Modeling
highway	elevator
indoor	yes/no	Indicating, if the elevator is located inside a building
level	integer	All levels with an elevator-chamber are separated by semicolons
wheelchair	yes/no	Indicating, if the elevator is wheelchair accessible
these characteristics can be added
bicycle	yes/no	Possibility of taking a bicycle into the elevator
operator	Operator	Name of the operator
operator_id	Number	Reference number of the operator
description	Description	More detailed description of the elevator. Name of station & description «from» floor & description «to» floor & number of elevator. Example "Zürich Löwenstrasse, Platform 31/32 after Passage Sihlquai, Lift 122"
ref	Number	Number/description written on the outside and inside of the elevator, which can be used to identify the manufacturer of the elevator, e.g. in an emergency.

The direction of the entrance and exit is defined by the footway which is leading to the elevator. The footway (highway=footway), which is leading to the elevator points, contains of a level=*-tag and if necessary also a indoor=*-tag.

Incline elevator

Incline elevators are enabling more mobilities for features in comparison to the usual elevators. They are for example proceeding wheelchair accessible entrances to the stations, closing hillside situations, providing connections to bridge piers or implementing particular architecture.

Inside the two elevator areas, which are located on the beginning and on the end of the elevator route, the elevator points and standard tags are added. The points are connected with a line, containing the tag (highway=elevator).

Ramp

If a ramp is located next to steps, the tag ramp=yes will be added to the stairs.

For a single ramp, the following tags are used:

Key	Value	Description	Image
highway	footway
ramp	yes/no	The footway has an inclination
incline=*	up/down	Indicating, if the ramp direction is going up or down (in drawing direction)
	* %	Accurate allegation of the slope. A negative value means that the ramp is going down (in drawing direction)
level	Integer	Indicating, which levels or floors are connected by the ramp. The ending points of the ramp get level tags
indoor	yes/no	Indicating, if the ramp is located inside a building

Guideposts for pedestrians inside buildings

The following abstract deals with the creation of tagging-suggestions about the topic "guideposts inside railway stations". The suggested tagging does not present the official course of action. We are thankful for any annotations and comments: MENTZ Kontakt Eifler

The aim of this method is to simplify the indoor routing with the aid of guideposts.

In intermodal routes, often electric information desks are proceeding support. But mostly people are left on their own while navigating throughout complicated railway station constructions. In this case, only simple and comprehensible guideposts could help. To have an idea about which signs to follow, the OSM-Data should proceed the necessary information in future.

Guideposts are captured with relations type=destination_sign. These relations are enabling to describe guideposts at the beginning and at the end of crosses in OSM. Examples, how these relations could be used for indoor paths: destination=* or destination:symbol=* destination:url=*.

It's important to only implement signs, which are crucially needed for finding the destination. Furthermore the data must be complete. The relations are only showing the direction, but not the destination. So if a curve doesn't appear and the passenger is still following the direction of the sign before, the possibility of getting into the wrong way could be the case.

To edit signposts pleasantly, there is a special style in JOSM to get the relation-members shown.

Members of relations

Relations are basic elements in OSM. Points can be used as data-elements, which are taken into the relation list. Each data-element gets a role and a description about which function is being taken in the relation. These are the most common roles:

OSM-Element	Role	Quantity	Description
+ level=* +guidepost	sign	1	The location of the guidepost. It can be connected to a footway, but this is depending on the location itself
	from	one or more	Connected to the footway. The location is placed on the position, from where the sign can be seen
	to	one or more	Connected to the footway. It is placed, where the passenger gets after passing the sign before

The edge has to be divided on every point, where a sign is placed. In the relation, a point can only have one role, e.g. the sign cannot present "to" and "from" in the same relation. It is possible to have more "to" and "from" roles in a relation, but only one sign is used.

Attributes

There is a difference between texts and symbols, thereby the relations look different as well. The examples of each attribute (Text/ Symbol) are listed further below. Following tags are used:

Key	Value	Description
type	destination_sign	"compulsory"
destination	*	"compulsory" Direction of the sign. It is enough to take the direction allegation of the sign
bicycle	yes/no	Indicating, if bicycles are allowed
foot	yes/no	"compulsory" Indicating, if pedestrians are allowed
destination:url		"compulsory at the symbol" Guidepost image link = https://wiki.openstreetmap.org/w/images/thumb/a/a6/Tram-Logo.svg/240px-Tram-Logo.svg.png Please consider the file format (PNG).
destination:symbol=*	*	Verbal written pictograms, which are used for the routing. Describes the destination with the help of colors or operator
note=*	*	In this tag an act can be added. For example mentioning the tram means, that the relation list will show "tram". These would facilitate the editing in JOSM

Symbols

Railway station

"The long version of the following abstract can be opened here: [1] "

The railway station is marked as a point in the middle of the station (not on the track). If it's divided in more independent stations, every single station gets its own point (e.g. Berlin Zoologischer Garten und S Zoologischer Garten). In case of stations which are "internal parts" of other stations the connection will be created with Site (Relation) (e.g. Köln Hansaring is a station part of Köln Hauptbahnhof).

Key	Value	Description
Note: Disused or abandoned railway stations can be captured with disused: and abandoned:. For example: disused:railway=station.
railway	station	Railway station, an operating station which has at least one switch where trains can start, end, cross, overtake or turn. This tag is added to all stations having access to public transport. These are mostly stations for passengers but also stations which are consisting of goods traffic.
	halt	Stops; are similar to stations, with the difference that there are no switches. There are difficulties to differ stations and stops, if the location is a divergence, crossover or a connection. In Germany these combinations are called "Haltestelle", but the components are captured separately.
	tram_stop	A stop for trams.
subway	yes	Subway station.
public_transport	station	Railway station, tagging stations for passengers with public-transport-schema. Stations, where only goods traffic is available are not captured with this tag.
name	station name	Station name, like it's captured on the signs. (don't do it!) should be considered.
railway:ref	station abbreviation	Station abbreviation; the code of a railway station. In Germany, Rill 100-abbreviations are used (e.g. KN for Neuss Hbf). If there is an abbreviation of a station from a railway company, an additional tag railway:ref:(Bahngesellschaft)=* can be added.
uic_ref	station number	UIC number of the railway station, international reference of stations worldwide.
uic_name	station name	UIC-Name; a valid international UIC name is given to the stop position.
railway:station_category	railway station category	Station categories in Germany: see here.
operator	operator	Operator of the railway station.
network	network name	Network or passenger transport executive, of which the railway station is a part of.
operating_times	same syntax as opening_hours=*	Times, when the station is under construction site and not available for public transport.

Railway station building

Railway station buildings are modeled as an area with the tag building=train_station.

Key	Value	Description
building	train_station
building:part	yes
level=*	integer	Number of floors
name	Name	Name of the station
operator	Name	Operator of the station
wheelchair	yes/no	Indicating, if the station is wheelchair accessible

Platform

Passengers are waiting for public transport on platforms. These platforms are tagged with public_transport=platform and can be created as points, lines or areas. Areas are recommended, when the platform is identified as an area (light traffic platforms and large bus stations). Generally, there is always a drive-in possibility nearby.

Key	Value	Comment	Image
public_transport=*	platform
tram	yes/no	Platform for trams
bus	yes/no	Platform for buses
train	yes/no	Platform for trains
subway	yes/no	Platform for subways
level	integer	Level or floor number of the platform
ref		The number of the rail track. If there are more rail tracks on a platform, the semicolon seperation will be needed. For example: ref=1;2
shelter=*	yes/no	Indicating, if the platform has a shelter
height=*		Height of the platform edge. Measured from the rail tracks
area	yes	Indicating an area
name	platform name	If the platform has an own name, it's captured with this tag. Rail track numbers are captured with ref=*.
description	Description of the platform	for example: "Odeonsplatz U3 U6 Bahnsteig"
wheelchair	yes/no/limited	Indicating, if the platform is wheelchair accessible
wheelchair:maxwidth=*	integer	Suggestion. Width of the smallest part of the platform. Important for wheelchair users. The value is indicated in meters.

indoor	yes	Is the platform located in an indoor area or in the underground?
covered=*		Indicating, if the platform is located underground
tactile_paving=*		Does the platform have supporting patterns for blind persons?

If a platform is having an edge, for example an access in the middle of the platform, a line for the surrounding outline and another line for the steps will be added. Both lines are part of a relation (type=multipolygon). The outline gets the role "outer" and the line of the steps (inside the outline) gets the role "inner". The tags from the previous table will be applied and added into the relations between the routes and stations, because the relation is now representing a platform.
For example: S-Bahnhof München-Pasing

Underground areas

Intermediate floors on huge railway stations

There are stations, where the platforms can only be reached by intermediate floors. These can be captured as areas. Intermediate floors often consist of shops and benches as well as of ways, which are leading deeper underground.
