Mapping Party goal

Map of the interior 

of the Politecnico di Torino

to improve

the existing new POLITO map,

available in the POLITO student APP

Mapping Party goal

Data collection phase

Autonomous collection of the data during this week

Use the printed floor plans 

of the Classrooms I and T 

of the Politecnico di Torino

to note:

• indoor element positions and attributes
• outdoor point elements

Data collection phase

Autonomous collection of the data during this week

Classrooms I -> GROUPS 2, 4, 5
Classrooms T  ->  GROUPS 1, 3

BOTH GROUND FLOOR &
-1 FLOOR

Data upload phase

During meeting of the 11 November we will upload all your data together

We will use OsmInEdit editor, a specific web editor focused on indoor mapping

ID Editor indeed missing of:

• function to filter data by level
• Simple Indoor Tagging presets
• indoor specific validation rules

Why OpenStreetMap?

Data created by

public institutions:

• rare updates
• sometimes with fees

Why OpenStreetMap?

Data created by

private companies:

• regular updates
• high costs

Why OpenStreetMap?

Data created by

private companies:

• restricted usages

Why OpenStreetMap?

Maps,

and the geographic data on which they are based,

are always only a
representation
of the real world

By René Magritte(1898-1967) - Image taken from a University of Alabama site, "Approaches to Modernism": [1], Fair use (Old-50), https://en.wikipedia.org/w/index.php?curid=555365

Why OpenStreetMap?

Relying on a single (and private)

map source

means being dependent 

on what the map owner

decides to display or not

Why OpenStreetMap?

A collaborative map allows

for a "debated/concerted" view

that is the result of different voices

Mapping is a community activity!

The community

Who uses OpenStreetMap

Universities and Research Institutions
World Bank, UN, MSF, Red Cross
Many national, regional and municipal institutions
National Fire Brigade
Civil Protection Department
ISTAT, Revenue Agency, Carabinieri

Who uses OpenStreetMap

What can be mapped

Transport infrastructures

What can be mapped

Adding

details

and

specifying  characteristics

What can be mapped

Verifiable data

Another mapper

should be able to go to the same place

and collect the same data

("verify" the data entered)

What cannot be mapped

Private information
Historical elements no longer present
Non-stable or temporary elements
Data obtained from proprietary sources

Mapping styles

Armchair mapping or remote mapping

tracing information by

photointerpretation of the satellite imagery

On field survey

using a GPS to record positions

using smartphone apps (OsmAnd, MapSwipe, StreetComplete...)

 using Field Papers to print a map of an area, draw on it and add notes, and load the paper back into OSM editors

OpenStreetMap data model

A geographical entity

is modelled by specifying

its geometry

and its attributes

OSM Geometries

NODE

RELATION

WAY

Defined by latitude, longitude and ID

Ordered sequence of nodes

Ordered sequence of nodes where the first and last node are the same

Describe how different elements are

related to compose complex elements

+ TAG

CLOSED WAY

Why mapping indoor

Mapping the distribution of the interior spaces allows to:

• enable indoor navigation inside the Politecnico di Torino
• reuse the data for simulations on emergency planning and optimization of flow
• support the building maintenance and BIM (Building Information Model)

OSM indoor mapping

OSM Simple Indoor Tagging schema

It allows to model indoor spaces

of public buildings:

• enabling indoor navigation/routing
• enabling floor plans and 3D maps visualization

OSM indoor mapping

OSM indoor mapping

OSM indoor mapping

building=yes

min_level=-1

max_level=1

OSM indoor mapping

Indoor elements

must be tagged with a

level=* tag

This indicates the floor level on which the element is located

OSM indoor mapping

amenity=pharmacy

level=1

shop=supermarket

level=0

amenity=parking

level=-1

OSM indoor mapping

Indoor elements can be modelled as

individual nodes (POIs)

adding the tag 

level=*

and the tag 

indoor=yes

OSM indoor mapping

Indoor elements can be modelled

 as areas (closed ways or multi-polygons)

The individual areas share the same nodes 

where they share a wall in real world

OSM indoor mapping

The value of the indoor key specifies the basic indoor element

indoor=room > indicates a conventional room with walls

The purpose of the room can be described by room=*

OSM indoor mapping

The value of the indoor key specifies the basic indoor element

indoor=area > indicates an area without walls

OSM indoor mapping

The value of the indoor key specifies the basic indoor element

indoor=corridor > an enclosed walkway area that connects rooms 

OSM indoor mapping

Connections between rooms are mapped with door nodes

A door node is shared between the rooms which the door connects

indoor=door

door=yes

level=*

wheelchair=yes/no

access=yes/private

Doors which are entrances to or exits from the building are additionally tagged as entrance=*

OsmInEdit

OsmInEdit (OpenStreetMap Indoor Editor)

is a web editor focused on indoor mapping

It offers indoor-dedicated functionalities

• Browse through all buildings and levels
• Import images building plans and custom TMS as background imagery

• Simple editing of indoor data: ​add or edit every single object in a particular level of a building with the support of dedicated presets: room, corridors, doors, furniture... and all common features (amenities, shops, offices...)

OsmInEdit

Add the Tile Map Service of the Politecnico floor plans as background in OsmInEdit
