This investigation focuses on the potential use of astronaut acquired photography for the validation of current, land cover maps. More specifically, this study is directed at assessing the potential for the use of astronaut acquired photography to document and validate land cover change. Space Shuttle, astronaut acquired photography is employed to test the potential utility of data that may be acquired by astronauts employing the Window Observational Rack Facility (WORF) on International Space Station (ISS). The majority of astronaut acquired photography has been obtained under conditions similar to ISS operations in terms of both spectral as well as spatial resolution. Validation of land cover maps utilizing this type of imagery is being accomplished through a process of comparison among three different land cover classification legends created from the Eros Data Center (EDC) Land Characteristics Database. Our study area is a subregional scale portion of an Advanced Very High Resolution Radiometer (AVHRR) based global Land Characteristics Database. The goal of this research is to attempt to establish: 1. which legend derived for this area provides the highest overall accuracy for the land cover classes present: 2. which legend is best validated using astronaut acquired photography; and 3. which classes of these legends best lend themselves to validation with astronaut acquired photography. Preliminary results indicate that astronaut acquired photography can be employed to validate land cover maps and that results achieved using this imagery corresponds well to those achieved utilizing Landsat data. .
