GRASS GIS is an extremely powerful application for manipulating and modelling large raster datasets such as Landsat 8 tiff bands. As GRASS users we are aware the application does not implement 'on-the-fly-projections' to ease the pain when adding data in a different projection in the way QGIS does.

NAME g.gisenv - Outputs the user's current GRASS variable settings. (GRASS File Management Program) SYNOPSIS g.gisenv g.gisenv [variable_name] DESCRIPTION When a user runs GRASS, certain variables are set specifying the GRASS data base, location, mapset, peripheral device drivers, etc., being used in the current GRASS session. The output from g.gisenv when invoked without arguments is directly usable by Bash.

Replying to marisn: adding just a u' ' would not introduce problems elsewhere :( Backporting r64834 could help in some cases but an overhaul of any string processing in wxgui is required with strict rules (that need to be created).. it's already done in r65462. Helmut, could you please test current 7.0.1svn if it still works (1)? GRASS LOCATION metadata are read into a list in R; helper function getLocationProj returns an spproj-compliant PROJ.4 string of projection information. The helper function gmeta2grd creates a GridTopology object from the current GRASS mapset region definitions. The new use_sf() and use_sp() functions permit the user to use "sf" and "stars" classes for raster and vector objects in R; use will Is there a way to run that "d.mon wx0" command more directly? I would like to run it under GDB but it seems like it's a separate process that gets started.

I can think of the following possibilities to try as this issue can be specific to installation: Try to see if the virtual raster is the issue. Use a real raster file (not a virtual raster) instead.

Last year (2013) I “enjoyed” a brain CT scan in order to identify a post-surgery issue – luckily nothing found. Being in Italy, like all patients I received a CD-ROM with the scan data on it: so, something to play with!

Usage: g.gisenv set="VARIABLE=VALUE" It looks unusual with two equals signs, but g.gisenv serves dual duty for getting and setting GRASS variables. If the user just specifies a variable name, it defaults to get mode. For example: g.gisenv GRASS_GUI text List of selected (GRASS related) environment variables

If run without arguments, g.gisenv lists all of the user's current GRASS variable settings.
