The Remote Sensing Resources project, produced by the Remote Sensing & Geographic Information Systems Facility at the Center for Biodiversity Conservation, develops learning materials focussed on practical aspects of accessing, visualizing, and processing remotely sensed data (typically satellite imagery). Whirl-i-Gig developed a series of "Interactive Tools" illustrating basic concepts like color mixing, scale, satellite sensor band sensitivity and near-Gaussian sensor response. All of the interactives were designed to be viewed in a web browser on the Internet or delivered on a CD-ROM or DVD for classroom use.
