The topowebb imagery is already predefined in JOSM. You simply open the
imagery menu in JOSM when panning over Sweden. There are also other useful
imagery predefined in JOSM and in iD, including the entire road network
from Trafikverket.

The Swedish mappers on this list may want to consider asking Lantmäteriet
for permission to use their orthophoto wms service for tracing. It is
available here for JOSM (after getting the permission):
https://kso.etjanster.lantmateriet.se/karta/ortofoto/wms/v1.2?LAYERS=orto050,orto025&FORMAT=image/png&TRANSPARENT=TRUE&STYLES=default,default&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&SRS={proj}&BBOX={bbox}&WIDTH={width}&HEIGHT={height}
(You need to select projection 3006 in JOSM first.)

We recently received permission to use the national orthophotos in Norway
for OSM, and national othophoto services are also available for OSM in
Finland and Denmark, so Sweden is the only Nordic country without
othophotos available for OSM. As in Sweden, the Norwegian orthophotos are
not open data, but is was nonetheless possible to get an explicit
permission for OSM. We discussed the case directly with Kartverket, our
Lantmäteriet equivalent, and then submitted this formal request:
https://drive.google.com/open?id=1ALN523MHK66Q1yPg7ttVJ30mQhXzVNWM.

You may also want to ask for permission to use the Swedish digital terrain
model. It is very useful for mapping tracks and paths which are hard to
discover in orthophotos due to the forest. The shaded relief representation
of the model is available here for JOSM (after getting the permission):
https://kso.etjanster.lantmateriet.se/karta/hojdmodell/wms/v1?LAYERS=terrangskuggning&FORMAT=image/png&TRANSPARENT=TRUE&STYLES=default&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&SRS={proj}&BBOX={bbox}&WIDTH={width}&HEIGHT={height}
(You need to select projection 3006 in JOSM first.)

In the meantime, this wms service may help identifying the areas with fires
in JOSM:
https://firms.modaps.eosdis.nasa.gov/wms/?FORMAT=image/PNG&VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=fires_modis_7,fires_viirs_7&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
<https://firms.modaps.eosdis.nasa.gov/wms/?FORMAT=image/PNG&VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&LAYERS=fires_viirs_7,fires_terra_7&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}>
This service displays 7 days MODIS and VIIRS data, updated every hour.
