OpenStreetMap
I have just an idea popping up that I want to share. In the city I live, there is a yearly big event. I think OSM is particulary suited to let the organisers display the map of the event (walking paths, small shops, parking) on OSM.
This would enable them to communicate effectively, to the partners, and to the general public using OSM.

There are a lot of tools that let you overlay your custom dataset over OSM map. They can be helpful to display paths for events effectively without mapping them on OSM.
Some resources- https://help.openstreetmap.org/questions/6102/can-i-add-a-custom-layer https://www.mapbox.com/help/adding-custom-layers/

Thank you for the links. I have now read a bit about temporary changes on OSM, and I am still forming my opinion about this. I believe the immense power of OSM is to respond rapidly to changes. Temporary changes should therefore as much as reasonable be reflected on OSM, imho.

@masticator The problem is that a full history of changes made in OSM is kept. Such modifications will be stored forever.
Another “limitation” of OSM is that data consumers can be out-of-date (e.g. OSMAnd) until a manual update. That means that some users will not have the event mapped on their phone, while users having downloaded the map while the event is present in OSM will keep it that way until the next update.
So in my opinion, only long or medium-term modifications should be mapped (>2 months minimum)

OSM is for things that are more permanent. This is a useful problem where maps are important for these temporary events. What I would recommend is mapping all that can be mapped in OSM the permanent structures the event location facilities, buildings, permanent gates or fences / parking. Then you can use that as the base map to make the map of the temporary event. The good thing about that is that there is less work you have to do the next year as the base map data is still there and you never have to start from scratch. You can share your custom event .osm file with others and it can be opened in tools that can display it. KDE’s Marble globe can load .OSM files, you also can render your own tiles and serve them up just for the event using the OSM stack and a modified theme.

Thanks for raising the issue.
If these things are permanent .. then by all means add them to OSM
If they are ‘cyclic’ .. say open/used every summer for example .. then it may be possible to map them using the open_hours tag to specify when they are usable.
If they only ‘pop up’ once then it is a one time map .. best to keep that out of OSM. By all means use OSM as the basis, no problem there .. a simple copyright notice for a paper map and your done.

Thank you all for your clear suggestions! It is clear for me what the purpose of OSM can be in the case of temporary events.

you may look at the map to CCCamp 2015th. http://campmap.mazdermind.de
