SAS/SPECTRAVIEW Software User's Guide

What is SAS/SPECTRAVIEW Software?

SAS/SPECTRAVIEW software is an interactive visualization product for viewing, exploring, and analyzing data as graphic images. The software reads a SAS data set, then based on your requests, creates two- and three-dimensional graphic images that represent the data. You can then visually explore both surface and interior views of the data to identify and analyze trends and relationships represented by the data.

SAS/SPECTRAVIEW Interface Displaying Images shows four different images created by SAS/SPECTRAVIEW from a data set containing data about sulfate concentrations in the air. The image in the Volume window (top right window) displays intersecting cutting planes, which produce slices of data perpendicular to each axis. The other three windows show two- and three-dimensional surface views of the data at the position of the cutting planes.

The software's capabilities apply well to a variety of applications, including oil exploration, environmental sciences, chemical analysis, pharmaceutical studies, financial analysis, and medical imaging.

For example, medical professionals might perform a CT scan of a patient's hand to determine the severity of a fracture. Then, using various SAS/SPECTRAVIEW tools, data from the scan can be explored from several angles, resulting in more information than static two-dimensional images. Multidimensional Medical Image shows a SAS/SPECTRAVIEW image of a hand created by requesting a cutting plane, which slices perpendicular along its axis. By probing the image, the software displays a density reading at a specific location.
