MultiSpec is a processing system for interactively analyzing Earth observational multispectral image data such as that produced by the Landsat series of Earth satellites and hyperspectral image data from current and future airborne and spaceborne systems such as AVIRIS.

The primary objective of MultiSpec is as an aid to export the results of our research into devising good methods for analyzing such hyperspectral image data. It has also found significant use in other applications such as multiband medical imagery and in K-12 and university level educational activities. There are currently in excess of several thousand known, registered users.

MultiSpec satisfies the following design goals:The implementation should be on a readily available computer platform which has adequate processing power, but is financially within the reach of any Earth science researcher (i.e., computer platforms < $2000).

The system should be easy to learn and easy to use, even for the infrequent user, using the most modern of software environments.The system should provide for easy import of data in a variety of formats, and easy export of results, both in tabular and in thematic map form.

Water Tank Functions 1.0 brings a comprehensive, user friendly math and science program. Middle school practice for interpreting line graphs and using functions. Students set the initial level; time delay; and flow rate of an on-screen water tank so that it's water level over time matches that shown on an adjacent line graph.

NSF Information is a small and very useful widget that keeps you updated with the latest RSS feeds from the National Science Foundation.

In a convenient tabbed interface, the widget automatically updates itself with breaking NSF news, funding opportunities, scientific discoveries, and publications as theyre released.
