Processing of Very High Spatial Resolution Multispectral Airborne Imagery for Mapping Applications. ^*FISHER, ROB , RUBY, JEFF and ANDERSON, JOHN , ¹ U.S. Army Corps of Engineers, Alexandria, VA, USA

ABSTRACT- Very high spatial resolution multispectral imagery (pixel areas < 1 m²) has the potential to become a powerful tool for multiple remote sensing applications. Land use/land cover mapping, agricultural monitoring, and invasive species detection are but a few applications that would benefit from increased spatial resolution. However, the relatively small footprint from airborne systems requires that a large number of frames be collected to cover a typical study area. This volume of frames introduces geometric and radiometric challenges that must be overcome for this data to be practical for most real-world problems. This paper describes a distributed processing methodology in which a large number of individual multispectral frames can be efficiently orthorectified and radiometrically normalized. Examples from several geographical locations across the country will be shown. Geometric and radiometric statistics will be presented. Scalability, application to other sensors, and future direction will also be discussed.

KEY WORDS: scalability, remote sensing
