Greetings
I have a labeled/classified image like this (hoje this displayed correctly
):
1 1 1 1 1 1 3
2 2 2 1 1 1 3
2 2 1 1 1 1 3
2 1 4 4 4 4 4
4 4 4 4 4 4 4
When I convert this to vector (areas) the pixel with value 1 in row 4 is
considered a different "area" from the one with all ones but it sh
hELLO all
Regarding the use of r.stats -1 input=image | sort | uniq
I have sent a message saying that this works just fine but...
I have only tested in WinGRASS 6.4.RC6). When I tried in Linux
(GRASS6.4.0RC6) I got this error:

hello
I am starting remote sensing based on ecw file.
I built a sub Goup, "Supervised" and I run i.class
i.class group=1325_13 sub=supervised map=1325_13.red outsig=outsig1
I am interested digitizes areas, I save them, and I go out of module. He
said that the data are recorded.
As I want to use
Greetings
I have a raster (FCELL ) that has a minimum value of 0.1312103122 and If I
try to have an image with just those values
r.mapcalc "minim= if(image==0.1312103122,10,0)" I get an all Zero image.
Then I opened the minim metadata and i see that in comments I have:
if(clustered.1 == 0.13121031,

please try a later snapshot or a fresh-svn-c
Hi
Since I saw today a message from Helmut, stating that 19-07 Snapshot is to
be updated, I decided to install an earlier version (from June).
While I was installing GRASS i got a lot of :

The data is stored in binary floating point, and 0.1312103122 isn't
exactly representable in that format. The closest representable value
is 0.0010cb7fe (hex) = 0.13121031224727630615234375 (decimal).
