Hi Markus,
My responses are inline.
I would prefer to get this fixed instead of not cleaning during
import. Can you provide sample data for testing?
Why spend time *fixing* this, unless you intend to eliminate the -c flag
altogether? It's not broken as far as I'm concerned. Mentally I view
Hamish et al,
I'm well aware of how to set an alias, but I appreciate the suggestion.
Thank you.
I think there is a misunderstanding here. If you would all please go back
to the original question (which was posed by someone other than I), you
will see that it asks for clarification regarding
By the way, it seems that the official stance is that it is preferred to
allow the automatic cleaning of non-topological data sets when they are
imported. However, I do want to point out that I have seen many, many
instances where this auto-cleaning actually causes problems, rather than
fixes
Hi All,
Does anyone know if there has been work done to implement the
Visvalingham-Whyatt line simplification algorithm in GRASS? I've been
using MapShaper's online implementation of this, but suspect it would work
a bit faster in GRASS.
Thanks,
Roger

Deleted it, but I still can't edit GRASS layers via QGis. I can toggle
edit mode, but the layer disappears from the QGis display and all of the
GRASS data types are unchecked in the Symbology tab of the GRASS Edit
window. Could it be some sort of mapset owner mismatch? I think I'd get
an error
This seems new in 6.4.2, and the included documentation doesn't reflect the
addition of this parameter. Is this intended functionality, or some sort
of error?

I realize this might be more of a QGis question than a GRASS one, but
perhaps the same problem has affected someone here. In QGis when I click
on the Edit GRASS Vector Layer button, I no longer can see the GRASS
layer and do any editing operations to it. The Symbology pane of the

I find this thread interesting. In my experience overlaying both raster
(orthophoto) and vector data in Google Earth with KML, EPSG:4326 has worked
with no problems whatsoever. So far as I know, GE does not apply a vertical
datum, it simply drapes the 2D data over its internal terrain model.
Hi Markus,
That's good to know. Can you tell me the bug number? I'd like to review
the details of it.
Thanks,
Roger

Hello GRASS Community,
I'm having a problem that I'm hoping you can help me find the source of.

B) that my data has some sort of topological problem which I'm unaware of,
or C) that there is a bug in v.generalize. The

Hi All,
I'm having trouble finding the solution to this in the GRASS Book,
what I've found so far creates a new data set as the result of an
intersection. What I would like to do instead is update the value of
an attribute based on whether the feature in that vector layer
intersects with those
of centroids: 2723
Number of areas: 2723
Number of isles: 2721

Hi All,
I would like to use an elevation mask to reclass certain areas in a
raster, while leaving the values outside the mask alone. Below are my
attempts so far. Unfortunately, when I export output raster, the
reclass appears to have been applied to entire raster. Is there a way
to do this
Figured it out. Used the following r.mapcalc expression:
r.mapcalc new_hillshade=if(europe_dem 100, 180, europe_hillshade)
I think I might be in love!

Hi Bob,
Just starting to use GRASS myself, so this certainly isn't an expert
opinion. You can reproject the data using ogr2ogr without having to
bring it into GRASS at all.
The best resource I have found so far for GRASS is the book by Neteler
and Mitasova, Open Source GIS, a GRASS GIS Approach.

Hi,

Tried the v.extract route - it didn't help. The little segments came
along. So I decided to look at the original data and pull one the
polygons from it, to see if I could spot anything strange about it. I
did find something, maybe, maybe one of the experts here can explain
it.
Here is what
is in:
/usr/local/grass-6.4.0RC4/scripts/d.redraw/d.redraw
I'm going through all of these now, and removing the dir and leaving
the script. Somewhat tedious, but the scripts appear to work.

I've noticed that a few tools in my GRASS 6.4 appear to be missing, or
