Hi I am still working on creating a percent shrub cover map using GRASS
and R and have a question regarding resampling. I have
shrub/non-shrub/cloud maps at 1m resolution and I want to resample those
to 30m pixels using the following logic.
The value of each output 30m pixel will be the
The Wiki page advises red/green glasses for viewing the images,
but I have the sneaking suspicion that the method shown actually
produces a red/cyan image, so red/cyan glasses would be better!
Could anyone confirm this? I don't have the right glasses to check
at the moment!
Cheers,

Ben,
I just checked the example anaglyph in the wiki with red/cyan glasses
(very old ones, from Spirit/Opportunity landing..) and it works fine.
cheers

Hi Glym,
Thanks for the reply. I have tryed on two ways, both not work for me (under
windows vista).
1) start msys; start grass without -mx ; and try to start python from inside
grass sesssion. The python keep stoped (no error message, but stay with only
python words on the console)
2) start
oops I typed grass -mx on email instead of grass -wx. Sorry.

Hi Glym,
But if you go to a DOS windows (using cmd)
type python (it starts python 2.6)
and try import sys, it works fine on text/DOS mode?
By the way, the pythopath was included as windows environment variable.
Any suggestion?

Hi everyone,
I'm trying to reclass a floating point raster (continuous values from
0 to 1) using a txt file with the following rules:
0 thru 0.2 = 1
0.2 thru 0.8 = 2
0.8 thru 1 = 3
But the GRASS shell replies
0.70 rounded up to 0
0.70 rounded up to 0
1.30 rounded up to 1
1.30

My current idea is to play with the bounding box
(extend) definitions when
defining the projection of the location and then
import-/reimport.
IS there a option in GRASS to shift a raster by a vector (x, y)?
I found such a tool in the ArcMap Toolbox.

Timmie

Hi Milton,
This is a common error I have come across, and shouldn't be a problem
with your Python installation. It is just a question of getting
PYTHONPATH and possibly

Nikos:
I tested... tested... tested... (almost all tests below) and I just
can't understand WHY i.pca does NOT perform data centering when using
MODIS data (raw, rescaled at 0~255 or 0~254).
The attached html file (exported from Tomboy note-taker) is (I suppose)
easier to read :-)

Sure: use r.region with relative coordinates
Some things are so simple :-)

You will find reading imagery/i.pca/main.c interesting and not hard.

:-). I tried once but there are many programming variables which do not
make sense on first sight. And this takes time... :-p
OK, it's sure not TOO hard. It takes time but if you stick on it you can

what do i have to do exactly to update?

sudo make clean

make install (again?)
Yes. However, note that the installation
sudo make distclean
there is no reason to run as root for anything but make install.
