You need to run db.connect to select a database backend to use
first. (There is no VAR file in the mapset yet)

see the help page for details, I usually just cut and paste out of the
examples. v.db.addtable can probably do this automatically.

Hi,
After hacking together some R + r.mapcalc code, I started to wonder about how
hard it would be to add distance-weighting to r.neighbors... Specifically,
the focal distance-weighted mean difference. An example of what I was trying
to accomplish can be found here:

hopefully fixed ready for testing in 6.5svn r42988 (v.edit).
devs:
maybe do this for 'v.in.ascii -e' and 'v.digit -n' too?
or move this into Vect_open_new() ? ...

Hi,
I have a MODIS land cover image that contains NULL values according to r.univar:
-

total null and non-null cells: 41884
total null cells: 17145

So, I tried to fill it with r.fillnulls and I get the following:

I am curious to know what the problem with r.surf.contour was. Usually
it does a great job as long as you take a moment to work around the
integer and NULL/0 issues.
Sorry that I quitted this discussion so silently, but I had to drop
Apart from the region resolution, it's land cover classes, r.fillnulls
will produce nonsense data: floating point. Rather use r.neighbors
with a modal filter, patch the original with the filtered map, that
would replace NULLs with the most common surrounding land cover type.

need to do anything else. Just create Vector by doing this. So, my

Does anyone know how I can find out if there are actually

I recently viewed OpenJump application written in JAVA which is also a

For your task the use of lists and the split tool may help.
The different lines have are seperated by a '\n' (which is interpreted as a
new line). After splitting the string into a line list you can make a loop

Okay, I turned it off by putting # in front of it. Now the line looks like

I'm trying to view attribute data for a vector file in the sample North
Carolina data using the GUI.
My steps:
In the GIS Manager,
1. Click the Add Vector Layer button in the toolbar
2. Click the Show attribute data in the settings pane below.
The Output window shows the following error:

Hi Dylan and everybody
I'm come back. I have past this week on R for uderstand what you do in

Now it's great for R but... I don't understand how make a loop in grass
in the web site we can read
for x in `seq 1 5`
do v.extract --o in=bclust
(apologies for interfering...)

about 40 FOSS geo projects are participating in all.
It would be great if folks could read through the 1-page overview
