RISTOSDS(1) General Commands Manual RISTOSDS(1)NAME
ristosds - convert several RIS8 images to one 3D SDS
SYNOPSIS
ristosds input-file-1, input-file-2... [-o output-file]
DESCRIPTION
ristosds creates a single HDF file consisting of a three-dimensional Scientific Data Set (SDS) from a set of HDF files containing one or
more raster images. All images in the input HDF files must have the same dimensions. If a palette is to be included with the images, it
should be in the first HDF input file. Only one palette can be associated with the images; any additional palette data encountered by the
utility after the first palette has been processed will be ignored.
OPTIONS -o outfile
Write the output to outfile.
EXAMPLES
The contents of a directory consists of 20 files named "storm001.hdf", "storm002.hdf". ... "storm020.hdf". Each file contains a single RIS8
with a 100 x 200 raster image. A file that combines these 20 raster images into a 32-bit floating-point SDS with the dimensions 100 x 200 x
20 can be created with the following ristosds command:
ristosds storm*.hdf -o storm.hdf

r8tohdf - convert 8-bit raster images to HDF format
SYNOPSIS
r8tohdf [number-of-rows number-of-columns] output-filename [-p palette-filename] [-c] [-r] [-i] raw-raster-image-filename-1, raw-raster-
image-filename-2, ...
DESCRIPTION
r8tohdf converts a set of raw raster images to the HDF RIS8 format and writes them to a file.
OPTIONS -p pallette-file
Specify the name of the palette file.
-c Run length coding. Compress the output data using run-length encoding.
-i IMCOMP Compression. Compress the output data using the IMCOMP method.
-r No Compression. Apply no compression to the output data. (the default).
EXAMPLES
A file named "rawras" contains a 256 x 512-byte raw raster image, and its palette is stored in a file name "mypal". To convert the informa-
tion in these files to an RIS8 without compression and store the RIS8 in a file named "ras.hdf", enter the following r8tohdf command:
r8tohdf 256 512 ras.hdf -p mypal rawras
A 800 x 1000-byte raw raster image is stored in a file named "bigpic". This data must be converted to a RIS8 without a palette, compress-
ing it using run-length encoding, then stored in a file named "bigpic.hdf". The following command will do this:
r8tohdf 800 1000 bigpic.hdf -c bigpic
A 300 x 400 raw raster image is contained in each of the files named "pic1", "pic2", and "pic3". To convert all three files to RIS8s, com-
press them using the IMCOMP method, and store them in a file named "pic.hdf", enter
r8tohdf 300 400 pic.hdf -i pic1 pic2 pic3
Different types of raster image data are to be stored in a file named "ras.hdf". The image data in the file "rawras1" will be stored with-
out a palette. The image data sets from the file named "rawras2" are to be stored with a palette extracted from a file named "mypal". The
images from the "rawras1" and "rawras2" files are to be compressed using run-length encoding, and the image in the "rawras3" file is not to
be compressed. The size of all images are 256 x 512 bytes. The following command is used to do this:
r8tohdf 256 512 ras.hdf -c rawras1 -p mypal rawras2 -r rawras3
