This is just a heads up: I've asked the "Bundesamt für Umwelt" BAFU if we can have access to their "Rapid Mapping" imagery for the disaster areas which would be useful to at least block/remove infrastructure that has been permanently damaged and divert people using OSM based apps away from the affected areas.
See https://community.openstreetmap.org/t/misox-rapid-mapping-daten-fur-osm-nutz...
Unluckily they haven't responded yet, so if anybody from the affected cantons / areas wants to coordinate adding some additional pressure on them, please get in contact with me.

PS: I have this niggling memory that a long time back we already tried to get access to their imagery in a similar situation but that they refused, does anybody remember?
