The CDF staff has recently developed a WWW CDF home page that is accessible from both the NSSDC and the GSFC home pages. The CDF home page provides informational services such as a CDF Tech Brief, a Frequently Asked Questions (FAQ) list, and the status of the most recent operational version of the software. The home page also provides access to the CDF User Support office via an automated mailing system and to the anonymous ftp accounts from which the software and documentation can be copied. The CDF home page is available from http://nssdc.gsfc.nasa.gov/cdf/cdf_home.html.
We have created a new mailing list for electronic discussions among programmers and users of CDF, both to encourage the CDF user community to share knowledge and experience and to reduce duplication of effort. To subscribe to this mailing list, please send an E-mail message to firstname.lastname@example.org with the body of the message as "SUBSCRIBE cdf-users".
The CDF staff has created a WWW interface to IDL for generating graphic images on the fly from user selections of data and plot options. The URL for the demo is http://bolero.gsfc.nasa.gov/idl/idl_web.html. In the near future, we plan to create WWW-based data analysis tools and information systems that will allow anyone to view NSSDC's data graphically and in real-time.
Members of the CDF staff have been working with members of the Space Physics Data Facility (SPDF) in a joint effort to develop a generic IDL/CDF-based scientific visualization tool called CDF Plot. SPDF staff is leading the effort and plans to release a beta version of the software early next year.
