you might want to run "g.region res=1 -a" to cleanse those resolutions.

that is ridiculously large. that map would take something like 13,500 GB
to store on your hard drive..

set the resolution so that the map is closer to 5000 x 5000 or whatever
is appropriate for your input map.

that's what DEFAULT_WIND gets set to if you didn't set up the default
bounds when you created the region. if you created the location
automatically it skips asking you. it's harmless, ignore it for now.

-s sets from the current region settings, shown with g.region -p.

from PERM:
g.region rast=map at some_mapset
  or
g.region saved_region at some_mapset
g.region -s
