Tools for multispectral visualization

I am working with Dr James Ferwerda in developing Web-based tools for simultaneous visualization and analysis of mutispectral images. The images show a 'quad viewer' that enables visualizing four multispectral bands simultaneously, a multispectral window that provides a drag and place window to analyze a section in a different spectral band and a spectral highlighter that displays a different spectral band at finger strokes.
