Dear all,
I am working with a raster with very large integers. That are stored as 64 bit
floats (imported from a GTiff). I wish to extract part of these values with an
integer division. The first approach was:
r.mapcalc 'short_ints = int(long_ints)/100'
However, this results in something
Hi Job,
looks like something is going wrong creating the attribute table for the
interpolation points vector. This is made with v.db.connect at the time of the
"Linking attribute table to layer 1" message. Which back-end are you using? The
SQLite default? I would ask you to verify whether
Hi Anna,
I was away last week and missed both sessions. Will you make a recording
available at some point?
Thank you.

Hi Vero,
in alternative you can use the WCS. A simple tool like wget is enough to query
the server:

Dear all,
I am trying to transform a polygon layer to lines with a command like:
v.to.lines input=country_borders output=country_borders_lines --overwrite
This command fails because GRASS tries to create a temporary table whose column
names are SQL keywords:
DBMI-PostgreSQL driver error:

Hi Markus,
I tried compiling GRASS with the -ftrapv flag, but it was failing (can't
remember now why). I was also supposed to create a replicating procedure, but
other things came up in the meantime. However, it looks like for rasters larger
than a certain size none of the modules depending on

Dear Anna,
thank you for the reply, indeed once I added the column parameter the module
completed successfully. The manual includes the following on this parameter:

I have been trying to use v.surf.idw the past few days without success.

Hi Maris,
thank you for the details. I can try compiling with the flag you suggest, but I
need a bit more time. Will let you know if I succeed.

Hi Stefan, thank you for the reply.
The outputs you request are below. v.rast.stats takes about 8 GB of RAM before
failing, only 1/4 of what is available in the workstation. I also tried
increasing the memory parameter but it never goes above 8 GB and fails all the
same.
Let me know if there
Thank you all for various replies. Some reactions:
1. The workstation has 32 GB of RAM and 12 CPU. What is the expected RAM
requirements for v.rast.stats?
2. v.to.rast also fails, see below.
3. What would be the way to check the health of the vector? The table in
Postgres at least is fully

Dear all,
I am getting the error "Unable to seek" with v.stats.error. There is not much
information that could point the cause, just a warning saying that some data
base files are not found. I checked the database connection and everything
looks in order (see below). Any hints on what may be

the label field was created by r.to.vect, I am not sure of its purpose. For
this particular record it contains an empty string (see below).
