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.

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
