The great problem in create a new map is that there is a database with rules of integrity. If the table sugarcane is linked to other table by primary/foreign keys i can’t simply delete it and put the new table in your place. This is my problem. I have to mantain the table sugarcane and keep updating it, when necessary.

Thanks…that was it.

I had not mentally made the association between layer and table.

Hello,

I’m a new WinGRASS user and have had issues converting ASTER bands into
composite raster scenes. I can import the first raster (r.in.gdal) just
fine, and r.composite successfully creates the new raster map. However,
when I import subsequent scenes and run r.composite, only a slice of the
new raster scene is displayed. I can display all imported scenes as 421
layer stacks, but they won’t display (completely) as rasters. Any thoughts?

Tom

Hi Otto,

have you find out, what the problem could be? I am still willing to use
grass with qgis, but -as written- qgis terminates when loading a raster
file from a grass project. I tried an older qgis version, but the error
is the same:

qgis: symbol lookup error: /usr/lib/gdalplugins/gdal_GRASS.so: undefined
symbol: G_no_gisinit

I’m afraid I made something wrong with my openSUSE 11.1 64bit…

Sorry for being so impatient,
achim

Hi,

thanks for answering and sorry for taking so long…

Im running suse 11.1 and I was installing both qgis and grass from the
following repositories:
http://teodori.org/repos/grass/openSuSE11.1/
and
http://download.opensuse.org/repositories/Application:/Geo/openSUSE_11.1/

As said deinstalling the old and reinstalling of the packages via yast
does not help. Now I’m using only grass, but I would really like to use
the comfortable qgis in future too.

Hi Achim!

It’s not clear to me which geo-repository you mean. Could you
please be
more specific?

First:

  • Which operating system do you use?
  • Which exact commands did you use to install grass 6.4 and which to
    install grass 6.3?
  • Why do you need both, version 6.3 and 6.4?

Now partially answering:

  • You are not “forced” to compile grass by yourself. There are
    binaries
    ready-to-(install)use.
  • Of course you can clean old libraries. If you installed grass from
    ubuntu’s repository for example, it should be easy to clean
    everything
    by just removing it (preferably with “sudo apt-get purge grass”).

BTW, Jachym Cepicky’s repository [1] is AFAIK always more up-to-date
than ubuntu’s repositories.

Kind regards, Nikos

I haven’t had the time to look at it yet. I will test as soon as possible, but
it will probably take some more days. I am very busy at the moment - sorry.

Hi Vincent,
I’ve tried the following command:

v.patch -ae input=sugarcane,sugarcane_update output=sugarcane --o

it returns:
ERROR: Output vector map is used as input

I’m using the -e and -a flags and overwriting the old vector layer, but the
message is the same.

I’m doing anything wrong?

Both vector maps have exactly the same columns and there aren’t identical
attributes:

Cat (integer)
Cane_id(Integer)

thanks,
Thyberio

If you are sure category values don’t overlap, then you can use the -a
flag. But in this case I would NOT give both arguments -a and -e;
i.e. given that the sugarcane map already has a related table, the
features from sugarcane_update will populate the table with new rows (it
is the reason why cat numbers, which tag geometrical features, should be
distinct from previous rows in the sugarcane table)…
Else you can try to create a new map :
v.patch -e in=sugarcane,sugarcane_update out=merge,

If you suspect duplicate objets (e.g. adjacent areas boundaries), don’t
forget to run v.clean with the tool rmdupl.

Vincent.

Having a look at the man page of the v.patch command, I was surprised by
a semantic ambiguity : saying v.patch “Create[s] a new vector map layer
by combining other vector map layers” sounds quite odd, shouldn’t we
say :“Create a new vector map by combining other vector maps”, given
that only layer 1 is supported ? well, maybe there is no confusion and
I misunderstand something ?

In the current french translation of wxpython GUI, there are several
confusions between these notions of maps and layers*, which IMHO should
be clearly distinguished if we want to show a coherent vector data
model.

Bye,
VB

  • I know I should keep working on translation files, but for the moment
    I’m really over-loaded.
