Comment (by hamish):
but I'm not sure about the example at the end of the old report.
that's another thin-area one which was fixed by the v.buffer2 replacement.
taking a hint from RT# 2765 I tried v.build.polylines on rstrct_areas and
reran the test. interestingly the buffer comes out completely empty! (ah
that is because cats are *completely* lost from centroids in that
process!?.
moving the centroids of the 2 small NW polygons into their respective
middles with v.digit didn't help. after assigning centroids in the
v.build.polylines output map it still breaks but a bit differently. this
time the big area looks ok.
we can simplify it back to a single 4 sided rectangle:
{{{
v.extract in=rstrct_areas out=rstrct_areas_cat4 list=4
v.buffer in=rstrct_areas_cat4 out=rstrct_areas_cat4_buf1000 dist=1000
}}}
which is:
{{{

that NW corner fails even with distance=20, which makes me posture that it
is an acute angle thing and not to do with the centroid.

ah..., moving the begin/end corner to the SW makes the SW corner buffer

Also interesting bit - I DON'T have such folder as C:\OSGeo4W
Setting this as a blocker because it's impossible to change bogous
GISDBASE value as WXGUI startup screen fails to come up and provide
GISDBASE choice option. Only solution is to start GRASS CLI or rm any
.grass* files. Both options are not beginner-friendly.

There is an bug in tcl used in current wingrass packages that prevents tcl
usage with non-latin filenames. In version 8.5.8.1 directories work fine
(couldn't find exact entry in tcl bugzilla, still I got a hint in #tcl
that there where fixes regarding encodings on Windows).
Test with:
{{{
mkdir āšņļ
wish
puts [file isdirectory [tk_chooseDirectory]]
}}}
Wiht current Wingrass included tcl/tk it returns 0 for āšņļ directory,
with 8.5.8.1 from ActiveState it returns 1, as it should be.
Tested failure with WinGRASS-6.4.SVN-r41363 on Windows Vista region set to
Latvia.

Hi Helena, Thanks for catching the ball here! Unfortunately I won't have time to mentor for GRASS this year, so I have only briefly looked at the ideas page. Perhaps the unfinished ideas from previous years could be moved to the 2010 page? Also what do you people think of a project to make vectors so that they don't have to be all loaded into memory, would that be too big of a task? Perhaps this has already been fixed in GRASS 7 (I know I haven't followed up too closely with the progress).

[GRASS-dev] Help test GRASS on the OSGeo LiveDVD
Hi there, FYI GRASS 6.4.0rc5 has been included on the new Live DVD/virtual machine/USB stick put out by OSGeo, along with NC and Spearfish sample data and some getting started docs. (and about 30 other free geo projects to try) The LiveDVD will be handed out to hundreds of people at various conferences over the few next months. I don't have the bandwidth to download the entire thing from where I am and it goes off to the printers very soon, so if anyone is interested and able to check it out and test that all is working as expected it would really help out. It's sort of a bad look if our app doesn't work correctly! version 3.0rc4 (or newer) at: http://download.osgeo.org/livedvd/ See the main help icon on the desktop for getting started info such as location of the sample data. thanks, Hamish ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
