DESCRIPTION

The Arc/Info MOSS export files are an ASCII format file readable by the
US Department of the Interior's MOSS public domain GIS. The file
contains points, lines, or closed polygon loops, and a 30-character
attribute field, called the "subject" value. The Arc/Info
coverages are converted into the MOSS files using the
"ARCMOSS" utility in the data conversion utility subsystem.
This module has a file browser, for selecting the ASCII input MOSS file,
which is scanned for markers. The markers are converted into AVS
geometry for use by the AVS geometry viewer.
Each marker is shown as a sphere, with radius controlled by the dial.
The marker does not have a color defined in this module, such that
it can be interactively altered in the viewer, and saved with
a network file.
