Scope of this page
This pages is intended to users and developers who want to test a GRASS installation (test protocol). As side effect, you can also showcase GRASS 6 using these commands.

Requirements
- GRASS 6 installation (source code and binaries download)
- Educational data set: OSGeo Educational data set North Carolina: data and description.
Extract the NC sample data set for GRASS:
mkdir $HOME/grassdata tar xvfz nc_spm_07_2007_dec20.tar.gz
Start of the program
GRASS 6 is started either from the menu (if installed therein) or from command line. In all cases, select mapset "user1".
# show available options grass63 --help
Expected result: the help text should be shown.
# start with old Tcl/Tk based graphical user interface (d.m) grass63 -oldtcltk # start with current Tcl/Tk based graphical user interface (g.gis) grass63 -tcltk # start with wxPython based graphical user interface grass63 -wxpython
Expected result: the selected graphical user interface should come up.
# start with text based interface grass63 -text
Expected result: the text user interface should come up.
Re-launch of GUI from command line
# start with old Tcl/Tk based graphical user interface (d.m) g.gui oldtcltk # start with current Tcl/Tk based graphical user interface (g.gis) g.gui tcltk # start with wxPython based graphical user interface g.gui wxpython
Expected result: the selected graphical user interface should come up.
Using gis.m graphical user interface
- Click in GIS manager on "Add raster" button,
- click on word "raster" which appears in the canvas,
- select "Raster name" button, select map "elevation",
- click "ok", map name should appear in canvas,
- click on "world map" button: should open GRASS map display
- and show elevation map.
- Try to zoom, to create a profile etc.
Expected result: it should just work.
Using wxPython graphical user interface
- Click in Layer manager on "Add raster map" button,
- select raster map "elevation" in properties dialog and click "ok",
- right mouse click in layer tree and choose from contextual menu "Zoom to selected map", map should appear in canvas.
- Try to zoom, to create a profile etc.
Expected result: it should just work.
Display various maps in GRASS monitor (not native winGRASS)
g.region rast=elevation d.mon x0 d.rast elevation d.vect roadsmajor
Expected result: GRASS monitor should open and show the selected maps
d.his i=elevation_shade h=elevation d.vect roadsmajor # set barscale position per mouse click into map: d.barscale -mt
3D visualiztion with NVIZ
# raster map and 2D vector lines map nviz elevation vect=roadsmajor
# raster map and 2D vector lines map and 3D vector points nviz elevation vect=roadsmajor points=precip_30ynormals_3d
Tests: navigate with the puck, interrogate map etc. (ADD MORE)
Expected result: should not crash at all but show maps as expected
Simple raster analysis
- TDB
Simple vector analysis
- TBD
Using QGIS' GRASS toolbox
- TBD
