Greetings
Thanks Markus and Milton for your help But...
Imagine that I'm running a GRASS Script with Module, and all GRASS
functions. How can I integrate it in there? I mean, the user selects a
raster and How can i use that input to run a Script that calls R? That is my
question. Because I can

Hi all, I am not sure I understand well the operation of v.split.
Keeping in mind the Florida coastline problem mentioned elsewhere in this

Question is, what happens to the attributes? No new attribute
Dear all,
FYI, there are 14 submitted abstracts that contains GRASS as a keyword.

I would like to know if anyone as tried to integrate or build an interface

tool has a lot of segmentation tools and classifiers that can be used in
QGIS. I wanted to know if it's possible to integrate/use in (or
Hi again,
New question. I downloaded the USGS seamless maps for lakes and ponds and
can't get them to fill. I thought I might be dealing with broken polygons. I
ran the file through v.build and v.clean. When I still couldn't get them to
fill, I looked at them in v.digit. It appeared that
I often do something similar taking a random point-sample of a given
raster using v.out.ascii and r.what. r.what is nice because you can
string together multiple rasters that you want to sample from. Say
multiple time-steps in a timeseries of rasters etc.
What I tend to do is something like:

converted to pointers when passing them into functions, but it isn't
possible to do the reverse

Hi all,
sorry for a little bit OOT message.
I would like to encourage you to publish a paper concerning
GFOSS-related stuff in our young journal called Geoinformatics FCE CTU
[1]. This year we are planning to release 5th volume of the journal.
If you are interested please send me a short
It would be very good to have OTB linked to GRASS!
I'm using it, and it is very powerfull, but very dificult too...

I've been reading about scripting and programming in GRASS, since I believe
the solution probably
involves writing some code based on r.cost.
But of course, any help is welcomed.
Try GRASS 7 r41926, r.cost got a new raster output option with the nearest
start point.
Indeed it is... I'll try it and report some results soon.
Thank you.

For a scientific database holding observed and measured values there are
two non-numeric (NAN) legitimate entries: 1 and 'below detection limits.'
Is anyone aware of a standard way of expressing these?
The problem is that the column needs to be of a numeric type because the

Dylan,
NULL means unknown, and 'less than 1' or 'below detection limits' means it

Adam,
Actually, it does.
Instead it means, can't be represented as a valid number.
One can have NULL in a text column, too, when the value is not known.
Another option is to use
