How to map a building - osiris-indoor/sample-maps GitHub Wiki
We are using the Simple Indoor Tagging proposal with some modifications (explained later)
Draft specification: http://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging
Example of indoor tagging: Aachen University
The first step is to download an area containing our building in JOSM. If not exist, we mustdraw the shell of the building. Then, every room, corridor or facility has to be represented in the model.
- We need an image of each level
- Then we use PicLayer plugin in JOSM to draw everything
- Transform the image to match the building in OSM
- After resizing and rotating we can draw over the image
building=*
min_level=*
max_level=*
non_existent_levels=*
|
Example:
building:levels=5
building=university max_level=3 min_level=-1 name=Lehrstuhl für Prozessleittechnik ref:RWTH=1381 roof:shape=flat university=institute website=http://www.plt.rwth-aachen.de/ wheelchair:description:de=Rollstuhlgerechte Toilette im Keller vorhanden wheelchair:description:en=toilet in the basement wheelchair=yes |

Indoor elements
indoor= [room|corridor|area|wall]
name=*
level=*
ref=*
Doors
door=[yes|hinged|sliding...]
Level=*
Building entrance
Entrance= [yes|main|...]
door=[yes|hinged|sliding...]
Level=*
|
indoor=room
level=3 ref=332 |
|
|
door=hinged
level=3 |
|
Stairs:
stairs=*
indoor=[room|area]
level=*
name=*
Elevators:
indoor=elevator
level=*
name=*
|
highway=elevator
indoor=room level=-1-3 |
|
- All elements on the same level get a level tag or are optionally member of a level relation.
- Optional level-outline (indoor=level)
- Multi-level features and repeated features
- level=* Examples: level=1;2, level=-1-5, level=-4--2
- repeat_on=*
Our server cannot make use of this point of the proposal yet, it is required to repeat these objects during the mapping task, using one level value for each.
After finishing the map edition, it is time to upload the data to the indoor server. The OSM file is processed by some batch scripts, the data is converted to GeoJSON and stored in MongoDB
