in the new BaseCamp version I noticed a new switch in the “avoid”-settings:
[x] Datum und Zeit von Sperrungen
(Date and Time of closed roads)
Does this mean that the Garmin img-file format supports temporary closed roads?
If yes, has this been decoded so that it can be implemented in mkgmap ?
Don’t know really. Maybe in the NT maps (that Mkgmap cannot make)…
Almost certainly not.
