# ristosds(1)

convert several RIS8 images to one 3D SDS

## 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
```
