Derrold Holcomb has been developing image processing software for 30 years. For most of that time, efforts were focused on advanced or experimental sensors. Currently, that category includes radar and hyperspectral imaging. Software development has always been viewed as a marriage between two components; a scientific understanding of the imaging phenomenology and a customer-based understanding of applications. A love of the Earth, informed by an M.S. in Geology and the unique perspective of remote sensing, has led to travels in over 100 countries. The travel focus has been on remote areas and varied cultures. Current study interests include history, historical travel and, increasingly, art.
