Re: [mapserver-users] GRIB files - gdal_translate
gdal_translate to extract particular bands from a grib file as a geotiff (or all the bands). For instance, the following would extract band 3 (total precipitation): gdal_translate -b 3 T126L28.grb total_precip.tif Converting the data on-the-fly to an image is the right way to work? Having MapServer access the grib file on the fly rather than depending on pre-translated extracts will reduce data duplication and may help avoid confusion about what is up to date. However, it is possible that there will be a performance penalty for extracting directly from GRIB. If so, it may not be significant enough to matter to you. What are the problems with Apache if I do not do so? I don't see how either approach relates to Apache. It is a data management and possibly performance issue with MapServer.

[mapserver-users] GRIB files
Hi all, I'm trying to work with GRIB files in MapServer but it's not working. I know that when we work with images we need to classify the output using [pixel] as a CLASSITEM and make classes for each value but how is it for GRIB files? I have several levels an variables in it. How do I classify them? Does anybody explain me?
