I opened the tif file I've extracted form it in QGIS and it looked like
the same thing, a line. What do I need to do to manipulate this as a
tiled/blocked data so? I want both things: make mapserver renders direct
from the GRIB file and either create GeoTiff files from them using

Hi Frank, tks for the answer.
CTL is an ASCII file that follows Grib files (at least here) and informs
the metadata of the Grib file. If anyone consider helping me my data
is available by ftp in ftp1.cptec.inpe.br inside bdados folder, as my
map file is.
I access them with

Hi people,
I used gdal_translate in the GRIB file I want to show with mapserver,
but there still is something wrong. The following is a partial output
from it:
Driver: GRIB/GRIdded Binary (.grb)

Hi there!
There is nothing wrong with your block X and Y size (161x1). It indicates that your data is not
tiled/blocked, so it is most likely to be read row by row. If the image looks strange is not because
of that. You have 98 rows in 0.02 degrees, so if it looks like a line, I wouldn't be
Hi, tks for the answers.
According to my gdainfo output file attached, can anyone tell me what
element could be a CLASSITEM?
I can see my grib using Grads but what tool do I use to translate

Converting the data on-the-fly to an image is the right way to work?

Roberto,
In MapServer you always classify rasters based on the item [pixel] but
you do not need to explicitly state a classitem.
This is a
