Fast Auroral SnapshoT Explorer (FAST) Data ArchiveEntry ID: FAST
Abstract: This project provides a common semantic framework for various Earth science initiatives. The semantic web is a transformation of the existing web that will enable software programs, applications, and agents to find meaning and understanding on web pages. SWEET developed these capabilities in the context of finding and using Earth science data and information.
The ontologies within ... the Semantic Web for Earth and Environmental Terminology (SWEET) provide an upper-level ontology for Earth system science. The SWEET ontologies include several thousand terms, spanning a broad extent of Earth system science and related concepts (such as data characteristics) using the OWL language. The ontologies can be downloaded from http://sweet.jpl.nasa.gov/sweet . To support such a large collection and adhere to the guiding principles, the concepts are divided, where possible, into orthogonal dimensions or facets in support of reductionism.
SWEET ontologies are written in the OWL ontology language. OWL is an XML language being adopted as a standard by the W3C. SWEET ontologies can be viewed using Internet Explorer 5 (or later) or Netscape 7. More specialized OWL-specific tools are available such as SWOOP or Protege. SWEET 2.0 is highly modular with nearly 100 ontologies organized by subject.

Quality Vis5D development has ceased at SSEC, but continues as the Vis5d+ Project on
SourceForge. This was initiated by Steven Johnson of MIT and now includes Jim
Edwards, the NCAR visualization team and others. We will continue to serve our
older versions of Vis5D but recommend Vis5d+.
Use Constraints System Requirements
Vis5D 5.1, the most recent version, works with the following systems:
* Silicon Graphics workstations with IRIX 5.x or later. Multiple CPUs are
used when present.
* IBM RS/6000 workstations with AIX 3 or later. OpenGL-based 3-D hardware
* Sun workstations with SunOS 5.x or later.
* HP workstations ... with HP-UX A.09.01 or later. PEX-based 3-D hardware is
* DEC Alpha workstations with OSF/1 V1.3 or later.
* IBM PC compatibles with Linux v1.2 or later. 90MHz Pentium or faster CPU
* Windows NT running on Intel.
* OS/2 running on Intel.
* At least 32 MB of RAM is recommended in all cases.
* At least 8-bit color is needed, 24-bit color is recommended.
* On systems without 3-D hardware rendering is done in software with the
Mesa library. 3-D graphics hardware is highly recommended.
The size of your memory determines the size of data set you can visualize. You
should have two bytes of memory for each point in your data set in order to
have maximum interactivity. However, you can visualize larger data sets with
