Abstract
As remote-sensing specialists, we all use images and
visualizations as the life-blood of our work. We receive data in the
form of images, we use software to manipulate images, we cross-reference
among images, and we use images to communicate our findings. And yet,
how well do we understand the cognitive and perceptual issues which make
our images more or less effective? These cognitive issues become all the
more important when we try to use images to convey essential concepts to
the general public, and when we promote the use of images in education.
Such cognitive and perceptual issues are the focus of “Visualizing
Earth”, an educational research project National Science
Foundation, Advanced Technology program. Applications “Visualizing
Earth” combines the expertise of educators, remote-sensing
scientists and cognitive psychologists, to explore cognitive issues
which are central to more effective use of remote-sensed images and
visualization software tools in education. In this paper, two of the
principal investigators, a scientist and an educator, share their
initial findings in relation to their efforts to use images in education
and public information
