Hello,
I tried out (Windows 7 home premium) the test protocol at
http://trac.osgeo.org/grass/wiki/HowToTestGrass6
and it mostly seems to work fine – please have a look below.
Kind regards,
Luigi
Requirements
• GRASS 6 installation: 6.4.0svn r37101 (2009-5-10) OSGeo4W version
• Educational data set: OSGeo Educational data set North Carolina: http://grass.osgeo.org/sampledata/nc_spm_latest.tar.gz
Start of the program
• Starts fine from menu icons (TclTk, Text, wxPython)
• grass64 --help (or -h or -help) only starts up grass the same way it was started last time (-text, -tcltk, -wxpython); it does not show the help of the command (OSGeo4W shell).
• grass64 -tcltk works OK.
• grass64 -wxpython works OK.
• Please, note that grass64 -version outputs the usual text plus an error message – see below:

Re-launch of GUI from command line
Works OK from GRASS in text mode.
Using gis.m TclTk graphical user interface
To add a raster map, click in GIS manager on “Add raster layer” button,
• Click on word “raster1” which appears in the canvas to enable in the lower part the raster map tool (should already be there) OK
• In “Display raster maps”, select “Base map” button, explode “PERMANENT” mapset, and select map “elevation” (click ok or use double click on map name) No way to explode “PERMANENT” mapset
No way to go futher…
• To add a vector map, click on the “Add vector layer” button OK
• Click on word “vector1” which appears in the canvas to enable in the lower part the vector map tool (should already be there) OK
• In “Display vector maps”, select “Vector map” button, explode “PERMANENT” mapset, and select map “roadsmajor” (click ok or use double click on map name) No way to explode “PERMANENT” mapset
No way to go furhter…
Using wxPython graphical user interface
Basic map display
• Click in Layer manager on “Add raster map” button,
• select raster map “elevation@PERMANENT” 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. Profiling on the elevation raster is OK but after closing the profiling window, there is no way to display anything else except the elevation map itself. If a new vector layer is added to the tree, it does not get displayed and the elevation map stays on even after removal and refresh.
Expected result: it should just work.
Digitizing
Does not work in Windows.
Extrude 2D vector to 3D vector
Extruded vector urbanarea with 500m elevation and works OK.
Display 3D house in NVIZ
NVIZ outputs the error window below
Display various maps in classical GRASS monitor
Does not work in Windows.
3D visualization with NVIZ
The command nviz elevation vect=roadsmajor crashes nviz.
Simple raster analysis
Raster algebra
Works fine – maps checked via wxPython GUI since no d.* command is available.
Raster statistics
r.univar ndvi works OK.
Simple vector analysis
Extracting from vector maps
I have done the following and works OK:
v.extract input=streets_wake@PERMANENT output=streets_wake_large where=CLASSNAME = ‘USHWY’
1107 categories loaded from table <streets_wake>
Extracting features…
Building topology for vector map <streets_wake_large>…
Registering primitives…
10001107 primitives registered
6166 vertices registered
Building areas…
0 areas built
0 isles built
Attaching islands…
Attaching centroids…
Number of nodes: 1097
Number of primitives: 1107
Number of points: 0
Number of lines: 1107
Number of boundaries: 0
Number of centroids: 0
Number of areas: 0
Number of isles: 0
Writing attributes…
v.extract complete.SQL support
Not entirely clear to me why the proposed command should test SQL support when schools_wake has attributes stored in a DBF table. However, same functionality implemented via the wxPython GUI works OK.
Vector statistics
Results as expected – works OK.
Transfer raster slope to vector segments
Not sure what I was supposed to do – I have done the following:
v.split input=streets_wake_large@user1 output=streets_wake_large_split length=1000
Building topology for vector map <streets_wake_large_split>…
Registering primitives…
10001164 primitives registered
6280 vertices registered
Building areas…
0 areas built
0 isles built
Attaching islands…
Attaching centroids…
Number of nodes: 1154
Number of primitives: 1164
Number of points: 0
Number of lines: 1164
Number of boundaries: 0
Number of centroids: 0
Number of areas: 0
Number of isles: 0
For v.to.db I just did the following:
v.to.db -p map=streets_wake_large_split@user1 type=line option=count
Reading features…

Skipped this because the North Caroline streets have a lot more classes
