[GRASS-user] Switching locations on-the-fly

[Bartolomei.Chris]

are you using the gui or in a bash shell?

In the gui, go to Settings, GRASS working environment, Change location and mapset

That will change it all on the fly. You can do this in a batch script as well but it's a little tricky - your .bash_history changes with changed locations and you need to reset your GISDBASE, MAPSET, and LOCATION internal GRASS variables, etc. Let me know if you want those steps and I'll dig them out of an old script I have.

Subject: [GRASS-user] Switching locations on-the-fly

   I need to import a lot of data each having one of several projections. It
is quicker for me to create a new location for each one, import it, then
re-project it to the base location and a layer-specific mapset. This
involves invoking grass, creating a new location, importing the .shp or
.gdb, shutting down grass, restarting grass in the base location,
re-projecting the new layer, then removing the (temporary) importing
location.

   Is there a way to switch locations within a running grass instance,
equivalent to creating/switching mapsets within a location?

Rich
