                               MAGELLAN ATLAS PROGRAM
                                 September 24, 1992
                             ==========================

     An updated version of the Magellan Atlas program has been released by the
Magellan project.  This program was designed to be used with the Magellan
CDROMs.  This program will do the following:

         o find the latitude/longitude of named features on Venus
         o given a latitude/longitude, find the mosaics which lie atop
	   that point and the Magellan CDROMs on which they are found.
         o the atlas now includes CDROMs up through 69
         o the named feature descriptions includes a short description
	   of the meaning (origin) of the name, and adds the diameter and
           crater type information listing in Schaber's "JGR - Planets"
           article of August 25, 1992.  Diameters for some coronae are also
           listed.
         o find all the named features (numbering 824) which lie in (or on) a
           specific mosaic has been added, in order to help those who wish to
           work with a specific CD-ROM or mosaic.  (This should be helpful
           to teachers, who may have only a limited set of CD-ROMs.)

     There is both an IBM PC and Macintosh version of the Magellan Atlas
program.  The programs are available using anonymous ftp at:

        ftp:      ames.arc.nasa.gov (128.102.18.3)
        user:     anonymous
        cd:       pub/SPACE/SOFTWARE
        files:    magellan.zip (IBM PC version -> PKZIP)
                  magellan.sit (Macintosh version -> STUFFIT, MacBinary format)
                  magellan-sit.hqx (Macintosh version -> BINEX -> STUFFIT)

     Also, the database files used by the Magellan Atlas program are available.
A description of each field is included at the beginning of each file.
The underlying databases include the center latitude/longitude given in
Schaber's article also, but they are not displayed by the atlas program to
avoid confusion.  The database files are available at:

        ftp:      ames.arc.nasa.gov (128.102.18.3)
        user:     anonymous
        cd:       pub/SPACE/MAGELLAN
        files:    names.txt (ASCII)
                  midr.txt  (ASCII)
                  mgn-dbf.zip (2 DBase files -> PKZIP)
